How to turn on networking from rescue boot

[vendor]

So...  I did a "sudo dnf upgrade" and things seemed to do well.  
However, when I rebooted, it hangs on bootup with the statment "Holding 
until bootup processes complete" or something like that -- I'm doing 
this from memory.  I tried with a couple of older kernels, but they also 
hung.


I assume that this is some transient thing associated with the upgrade.  
Over the years, I've had glitches appear on an upgrade and disappear on 
the next upgrade.  Accordingly, I'd like to boot into rescue mode and 
see if I can upgrade again.


However, I've forgotten how to turn on wifi networking from rescue mode.

Can anybody point me to a tutorial?

Thanks,

billo

Well, that solved it.  It installed without a hitch.  I *think* what 
happened was that the installer saw some residual F25 partitions (I must 
not have deleted the F25 /boot/efi partition), and was trying to install 
as a triple-boot F25/F26/Win10 rather than dual boot F26/Win10.  It was 
respecting the stuff that was already in the EFI/fedora directory in the 
/dev/sda1 system EFI partition.  But, of course, the F25 partitions were 
*mostly* gone, so it crumped on boot when it tried to defaut to a F25 
boot up.  When I used gparted to delete everything linux-y and deleted 
the fedora directory in the /dev/sda1 EFI directory, it installed 
without complaint.


I think my big error was not making sure that *everything* F25-related 
was gone.

Hello,

The more "interesting" way (if you want to learn how it works?) would 
be

to boot from an external media, mount the newly installed F26 and
`chroot` into it. From this point, you should be able to restore grub :

* this page from archwiki explains how to install grub on a UEFI system
: https://wiki.archlinux.org/index.php/GRUB#UEFI_systems

* /!\ You may want to run `os-prober` in order to check if the windows
installation is properly detected.

* the "proper" EFI partition is most likely /dev/sda1

Timothée



Yeah, it sees it.



%sudo os-prober
/dev/sda1@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot 
Manager:Windows:efi


... and I can boot into Windows from the same menu that has the old F25 
kernels listed.


I think I'll just delete all the linux partitions, and delete the 
"fedora" directory of the EFI directory on /dev/sda1 and try again.  
What's the worst that can happen?

Just to be clear.  This is a new installation on a machine that used to 
have F25, not an upgrade.  The old /home directory is destroyed, etc.


Thus, it's no big deal for me to delete partitions 6-9 and start over.  
I'm not trying to save data, I just don't want to make the Windows

Oh oh. I screwed up my F26 installation. Help keep me from destroying everything....

[vendor]

So, I decided to do a clean installation of F26 over my F25 
installation.  My old configuration was:


Dual boot HP laptop: Win 10, F25.

F25 had an encrypted /home partition, a separate /swap partition (I know 
I don't have to have one, but I'm old), and an unencrypted / partition 
where, I thought, /boot/efi lived.


I do the installation using the GUI from "Install to Hard Drive" on the 
USB live distro ((KDE spin), and choose "delete everything associated 
with only F25."  I am required to create a /boot/efi partition by the 
GUI.  So I do (I vaguely remembered that F25 was happy using the system 
uefi partition, but I don't remember).


I install, and everything seems to go well.

Then I reboot, and my old F25 boot options come up (i.e. a list of F25 
kernels and the Win 10 bootloader).  Of course, it can no longer find 
the F25 kernel.  The Win 10 boots up fine.


So... I'm figuring I mis-configured where to put the boot directory, and 
somehow it's finding the old one (which may well be in the system uefi 
partition -- I don't remember).


The last time I had a problem with this, I ended up trying to move 
directories by hand, and wrote over the Windows boot loader, which 
caused me no end of headaches.  I don't want to make that mistake again.


Here's what's on my hard drive:

sda1: "EFI system partition", containing BOOTSECT.BAK   EFI

If I have to re-install from the USB, what mistake did I make and how to 
I not do it again?

I vaguely remember something like that happening to me in the past, 
where I had some piece of Microsoft software that I was using, and then 
about a month in it started demanding a product key.


It may be that Microsoft has simply decided not to enforce this.  I keep 
hearing rumors that they want Windows 10 to be used as widely as 
possible, and are considering making it free.  Who knows...


I guess I'll find out, eventually.

Virtual software on Fedora is free of charge.  For simple programs you
should not need a stand alone system.  If, however, you do need a full
system then there are plenty of refirbs for cheap.

Cool!  I just downloaded and installed it.  It installed without a hitch 
with Virtualbox, though Microsoft insisted I create an account -- which 
I've never done before.   I didn't know that Win 10 was free from 
Microsoft.


It's funny, I started using Linux back 20 years ago or so.  Back then, 
you always had to have a copy of Windows on your box because there was 
always *something* that wouldn't work or run or whatever.  Over the 
years, I've slowly used Windows less and less, and this last time I 
installed, I didn't bother making my machine dual boot -- I never "have" 
to go to Windows, except for font issues in presentations and such for 
compatibility at meetings.  My brother-in-law was having problems with 
his laptop the other day and asked me to help him.


It was running Windows 10.  I turned it on and could hardly recognize 
it.  I didn't know where anything was.  It took me over two hours of 
reading tutorials and doing searches to make enough sense of things and 
get him going (after all, tasks are tasks no matter what your OS is...) 
.  And even then I still don't know how to do a number of system things 
that I used to be able to do as late as Windows 7.  I told myself I 
really ought to get a book on Windows 10 administration and get on the 
ball, but my eyes just glazed over.  I thought systemd was adding too 
much complexity and too many layers of BS.  It's got nothing on 
Microsoft.  Windows 10 seems pretty opaque to me.


But there it is, sitting in a window.  Thanks for the link.

A non-registered OS will simply not draw updates and not nerf the

I went on ebay and looked at win 7 distros for sale.  It seemed to come 
in two flavors, one flavor came with a busted disk drive for about $40 
and another without a busted disk drive for about $100. Both kinds said 
they came with appropriate certificates, etc.  I wasn't sure if both 
could be thrown on a Virtualbox disk.  I use Virtualbox for an old win 
XP distro I have for previewing LibreOffice presentations on PowerPoint 
to make sure fonts are OK. Unfortunately the e-transcript sofware 
requires Win 7 and above.


I've had that virtual disk for years -- I just keep copying it over when 
I install new versions of Fedora or Debian. I'm sure it's not secure, 
but I only use it for about 10 minutes at a time, and not when connected 
to the intenet.  It's been so long since I've used Windows for anything 
other than basic wordprocessing at work, I don't have a clue what will 
and will not install on a virtual disk.  Do you know if those OEM $39 
distros will actually work in Virtualbox?  I really don't want to pay a 
hundred bucks for a distro I use once every two or three years.

Nope.  Yeah, I saw that site.  It's not readable in vim, kate, more,
less, etc.  Kate complains of unrecogizable encoding.  Gedit
complains of invalid characters.  I was kind of hoping to be able to
look at in Linux, and not move to Windows and Notepad++.


I apologize for besmirching your search skills.  :-)

If Tom's suggestion doesn't work, it is probably in exe format.  If you
can contact whoever sent it to you, you could ask them to send it as a
text file instead of a ptx exe file.  If they created it, they must
have the commercial product that would allow that.

If you can't get it in a text format, then it is probably going to need
that windows tool to read it.  As a long shot you could try unzip on it
to see if the encoding is just a compression step.

Alpine question

[vendor]

I don't know if this is a fedora question or not, but I'm hoping it's an 
OS-level config issue.

I have a laptop that runs Fedora 24, and a virtual machine with CentOS that I 
use as my mailserver.  I'm an old fogey who doesn't like all this multimedia 
mail stuff, so I still use pine/alpine and text emails.

The problem is this.  When I ssh to my virtual machine from my laptop and run 
pine, it will work for a few minutes and then hang. If I close the terminal 
(which kills pine) and ssh in again, it works again -- for a few minutes.  Then 
it hangs.

I don't *think* it's a pine/alpine issue itself. If I come in using shellinabox 
and open pine using a browser terminal, it doesn't happen.  If I use some other 
client, e.g. roundcube, it doesn't happen.

If I just ssh in and do other stuff, it doesn't hang.

Finally, it only happens at work.  My workplace has a very restricted wired network and a 
very open wireless network.  We are supposed to "work" on the wired network and 
attach our cellphones and private laptops to the wireless network, which solves a lot of 
social engineering type security issues. If you want to do streaming media, or download 
cute stuff, don't use the work box -- use your own.  So, the problem occurs on this 
wireless system.  It doesn't seem to happen when I connect from my wireless at home.

Any pointers?  It's very frustrating...

Thank you.


If you mean simply to create an animation like that, and not some
integrated-into-the-desktop thing, then the default answer in the open
source linux world is almost alwasy "Blender."

See, for instance, https://www.youtube.com/watch?v=IiSMEbNIPtc

Here's the Blender site:

https://www.blender.org/

You can either download it an run it from your home directory or install
it using dnf.  I usually do the former because I like having the very
latest version and there's often a teensy delay in upgrading it in the
repositories.  Not much of one, but I'm a Blender junkie.

Be aware that Blender is like most high-powered modeling animation
packages -- it has a nontrivial learning curve.  The up side is that
once you've done the work for that learning curve, you can do all sorts
of cool stuff with much less marginal effort.

I use Blender for forensic animations.  For a simple rotating body with
an arrow through it, it took me about two hours to get it work right.
However, from that point on, each *different* similar animation only
took about 5 minutes.

And, for Star Wars, obligatory hat tip to:

How to get NetworkManager to accept my spoofed mac address without using the gui?

[vendor]

So, I'm sitting in a hotel in North Carolina that has two levels of wireless -- 
free and paid.  I tried the free, and it's too slow.  So, I decided to pay.

But I can't.  The system has mapped my mac address to the free sign up, and 
there's nothing I can do to get it to change.

No problem, I tell myself.  Back in the day, I used to spoof my mac address all 
the time.  I'll just change my mac address, reconnect, and hook up using that.

Now, back when I used to do that a lot, I was running Fedora 19, and it was 
easy:

It was just...


%service NetworkManager stop
%macchanger -a wlo1
%service NetworkManager start

... and voila!


However, this time in Fedora 24, that doesn't work.

Also, think about LightZone.  They require registration, even though it's open

of editing.  It's also in Java, so you don't pull in a lot of Gnome and KDE

Do you mean Gwenview rather than Genview?  I've been following this thread a little, and there's no 
"genview" or "Genview" available when I poke around using dnf, at least with my 
repositories.  Doing a quick search on the intertubes reveals a couple of "Genview" programs, 
neither of which seem to apply here.

If you mean Gwenview, I'm getting the impression the OP wants more integrated 
editing capabilities, i.e. he wants the lightable capabilities of Digikam 
combined with the editing of ShowFoto, but in a lightweight program that 
doesn't drag in all the dependencies of Gnome of KDE.

Gwenview doesn't really have the immediate editing things, and I get the 
impression he wants a more traditional directory-tree-in-a-sidebar kind of 
interface.

But I could be wrong...

Hi,

I found a refurbished Lexmark laser printer online. Unfortunately,

Does anyone know if those drivers would work on Fedora 23 an onward?

Since I have a *very* old Fedora distribution, Fedora 13, the printer
would be supported.

However, I would not want to buy the printer then not have it work

Does anyone know how to determine if the Lexmark drivers would work on
the current Fedora distributions, 23 and 24?

Well, it looks like there's a linux driver claiming support for Fedora 23.

Once upon a time, Ed Greshko  said:
No, it isn't specifically a Gmail issue, it is an issue from the

Yahoo publishes DMARC policies that say messages from a Yahoo domain in
the From: header should only come from the Yahoo servers.  Gmail (and
other sites) recognize and follow those policies.  When a Yahoo user
sends email to a mailing list, and the list server resends the message,
it doesn't come from a Yahoo server, so sites that follow DMARC policies
reject the message.

The correct solution is for the mailing list software to be changed to
rewrite From: addresses.  Newer versions of Mailman support this.  The
address rewriting is annoying, but is the only true solution to being in
between sites that publish and honor DMARC policies.



Yeah, this was a big issue on another mailinglist I belong to (NAME-L at Emory 
U).  We had a bunch of people who simply disappeared from the list for a couple 
of months.  Then they all reappeared with obviously re-written addresses.

That meant that none of them could get backchannel responses by just choosing "reply" 
because Emory didn't decode the addresses for response in a reply.  Since that list is associated 
with an organization that keeps a list of public email addresses of members, the workaround was to 
have to look up the address if you wanted to respond individually.  But that doesn't happen much.  
All in all, it turned out to be a blessing in disguise because a lot of people were in the habit 
hitting "reply all" and posters would get two responses -- one to the mailinglist and one 
personally.  And it turned out that most of the people who were either offenders *or* victims of 
the double mails were mostly Yahoo/Gmail folk.  Win. win.

I think it's a local configuration problem. I was in this same
environment a year ago and this worked with the same hardware (well,
it was a different building so different physical APs but the people
managing it are the same).



Yow.  I wasn't expecting that.

Well, this weekend, I'll plug in a little Chinese usb wifi adapter that 
exhibited the same kind of behavior you described, at least when I played with 
it with Fedora 22.  I have four cheap usb adapters, all of which are *supposed* 
to have the same chips.  Yayy ebay.  Two of them do the same sort of thing you 
write about -- run fine for 20-30 mins and then crump.  One of them only does 
it when it's talking to a Cisco router.  Two of them work great.

I'll see what wireshark has to say.  Maybe what I find on my toys might help.

No change.

Intel NUC is getting 98kbps downloads of the exact same file from the same AP 
as the Mac, but the Mac is at 1200kbps. And today, even an 'nmcli c down'
and 'nmcli c up' cycle does not improve the NUC.

Hi,

I have a super annoying problem that is not Fedora specific, but it's
been driving me nuts for a few weeks. Any idea for a more appropriate
forum to post this in is as useful as an idea what's going on or next

[snip]



I think this is a problem that comes up with Linksys routers in general, not just the 
WRT600N.  It used to happen to me with an older Linksys device, and I went through the 
"try changing the MTU, try changing the firmware, try resetting to factory..." 
etc.

All that stuff.  Sometimes it would work for awhile, and sometimes it wouldn't. 
 If you go to the Linksys forums, it always seems to boil down to bad firmware 
-- whether ma nufacturere or dd-wrt for any number of models of products from 
this brand.

The only thing I ever found that seemed to work for one person (it didn't work 
for me), was to shield cables or move the router away from the cable modem.  
The claim was that it was electrical noise:

http://www.speedguide.net/articles/router-speed-drop-solved-1885

Other explanations I have seen include:

1) You are dropping a lot of packets because of noise and the router 
automatically drops down to lower bandwidth when that happens (my old DSL 
router did this all the time back in the day because I had a noisy phone line)

2) You are in an area where there is congestion on a particular channel (e.g. 
you live in an apartment and all your neighbors are simultaneously downloading 
porn and playing World of Warcraft 24 hours a day)

And, I have to admit, when I looked at my router, it did follow a pattern of 
dropping increasing numbers of packets before it crumped.

But mostly it was just Linksys/Cisco consumer product issues.

See:

That's not true. It varies device by device. Some new devices have
excellent drivers. Always check http://linuxwireless.org/.

Gavin,

Many drivers have debug mode, which will output to the kernel logger
(`journalctl -k` or `dmesg`). It varies by driver, and you'll have to
poke around in /sys to find it, and probably write 1 to a file.
Additionally, putting wpa supplicant in debug mode `-dd` option to
`/usr/lib/systemd/system/wpa_supplicant.service` might get you more
information.



Well, yes and no.  Sure, if you know what chipset you are looking at, etc. you 
can look it up.  But...

1) That list isn't 100%.  I have bought a few adapters after looking them up 
that were supposed to work and didn't.

2) I'm one of those guys that tends to collect computer detritus.  I'm the guy who 
"just happens" to have the HDMI to micro-HDMI adapter in his backpack when 
someone can't hook up their laptop for a PowerPoint presentation.  Just because.  Oh, you 
want a parallel printer cable?  A Zip drive?   I just happen to have one here somewhere...

Folk like me seem to come in two flavors, I've observed.  It's like buying power 
lawnmowers.  I have friends who buy these $1000 push lawnmowers and say "It's worth 
it!  These things will last 30 years if you take care of them," and they carefully 
do all the maintenance things you are supposed to do -- only use ethanol-free gas, keep 
them sparkly clean, sharpen the blades so you could shave by sticking your face in the 
rotors, etc.  Then there's folk like me, who go to Walmart and buy the cheapest damn 
piece of shit that works for $100 bucks.  Then I use it until it fails (usually 1-2 
years) and then go out and buy another.

Which way is better?  It depends on how good $100 lawnmowers are in 2045.  
Because I'll be in Walmart buying a new one, and my friend won't.

Same thing is true with computers.  Some folk go out and buy the $5000 laptops 
because, you know, they are the best and you can keep them for 10 years (I 
actually fell for that in the late 1970s when a selling point for the first 
8-bit personal computers was that the motherboards used gold solder so the 
computer would last 20 years.  I paid an extra so I could get an Exidy 
Sorcerer, I think it was, with a custom motherboard.)  I stopped doing that in 
1980.  Other folk (like me) make a point of buying last year's laptops for $500 
(and preferably a demo from Staples for $300), and get a new one every year.

And the same thing's true for these kinds of accessories.  There are these guys and gals 
who go out and buy the $300 usb wifi adapters and the $200 cables and stuff because, you 
know, that's the "good stuff."  And there's people like me who go on Ebay and 
buy 10 cheap things that are borderline disposable with the idea that if one of them 
works, you're ahead.

And when you do it the second way, you don't always know what chipset you are 
getting.  God only knows what they shove in those little toys they make with 
child slave labor in those sweatshops in Guangzhow and sell for $1.99 with free 
shipping.   However, you do know that if they were selling the same thing last 
year, it's probably old enough so that the current linux drivers support it.  
And if you buy 5 different kinds, at least two will work.

Speaking as a fedora user, this has happened to me a number of times over the 
years.  I've posted to this and other forums each time and get the same kind of 
responses of tweaking this or that (particularly the MTU).

And... every time, it either didn't work or worked poorly.  I am convinced it 
was the driver.

What I ended up doing was go out and buy a slightly-out-of-date external usb 
wifi adapter.  It has to be an older one -- not a brand new one or you run into 
the same problem of having a too-new adapter.

Then, I use the thing for a couple of months (or until the next version comes 
out), and viola!  It's magically working again.

The laptop I'm using is a case in point.  I bought it in the early days of 
Fedora 22.  Nothing I tried would make the damn thing go for more than about 5 
minutes.  In installed Mint, and it didn't work.  I installed Manjaro, and it 
didn't work.

So, I plugged in my three-year-old usb wifi adapter and chugged along with that 
until Fedora 23 came out.  And, voila, it worked perfectly.

Things aren't nearly as bad as they were 20 years ago, when you had to go out and buy an 
obsolete machine or else spend a month trying to make the hardware work.  But 
occasionally, the drivers are still not quite "there" yet on brand new boxes.

You might try accessing the CUPS daemon via

I have been doing that.
But as far as I can see, CUPS does not offer any way of seeing toner level.

I use fail2ban and you can configure custom filters to snag log entries of

This is a little off-topic for fedora, but since you mentioned it I have

I just installed it on my F23 virtual machine (755 MByte download, 579

I watched a friend get his box hacked four seconds after establishing a

Did you mean "hacked" or "attacked?"  It seems to me that if there are 
successful intrusions by scripted attacks within four seconds of installation of a linux distro, 
it's either the wrong distro or it's wrongly installed -- with or without selinux enabled.

The problem I see with selinux is that it is so user-unfriendly.  These kinds 
of things always seem easy and straightforward to someone who knows it well.  
That's the nature of skill, regardless of the kind of skill it is.

It reminds me of when I was a medical student many years ago, going through my 
Pathology laboratory.  We were studying inflammation and looking at white blood 
cells under the microscope.

I looked through the scope and all I saw were little dots.  It made no sense to 
me.  And I said so.  I could see the resident getting more and more frustrated 
with me as he kept telling me over and over again how to tell the difference 
between the various inflammatory cells -- it so trivially obvious and I was 
such a moron.

Then, four years later, I was the resident physician in pathology and I was assigned the 
second year pathology lab.  The student was looking through the microscope and couldn't 
tell the difference between a polymorphonuclear leukocyte and a plasma cell -- two cells 
that look *totally* different.  I remember getting more and more frustrated with the 
student as I told her over and over again how to tell the difference.  But she just 
couldn't see it!  I thought to myself "What a moron."

That's what four years of staring through a microscope 18 hours a day buys you.

That's what I think of when I read these discussions.  If someone is struggling 
with something like this, they may seem like morons, but it is usually someting 
*other* than simple supidity or laziness that is the reason.  It's because the 
barrier to doing it is greater than the perceived benefit.

Yes, selinux is a great tool, particularly for large multiuser systems that 
serve a lot of things.  But the very thing that makes it a great tool for these 
systems makes it very complex and intrusive, particularly on one- or two-user 
systems that serve personal things.  Do we really need a lot of user-level 
permission tweaking when every user on the machine is an administrator?

The selinux protections at the process level are obviously beneficial, but that's often where the 
barriers are the highest.  Selinux provides exquisite protections at the process level for servers. 
 Personally, that's where the most frightening attacks on my boxes have come from in recent years. 
But, selinux frequently takes a server that "just works" and turns it into one that 
"just doesn't work."  Then, you have to figure out whether the misconfiguration is from 
the server or from selinux, and how to tweak both so that one will let the other do its thing.  
And, no, the answers are not always obvious.

There is a truism that I remember being told about computer security a long, 
long time ago that usability and technical security are inversely related.  At 
some point, when you increase the technical security enough, you will have made 
the system unusable to the point that your users will simply start going around 
it simply to get their work done.

I remember bringing some data to a federal military installation once on a flash drive. 
The military had recently put in a policy that flash drives were not allowed, and they 
had some sort of enterprise-level monitoring software that watched the usb ports on every 
machine in the network.  I gave the flash drive to the agent and said "Look, here's 
my results.  I don't know how you are going to look at them, but this is what I've 
got."  The agent powered down his computer, unplugged his computer from the network, 
booted it up again, put in the flash drive, downloaded the data, pulled out the flash 
drive, powered down the computer, plugged it back into the network, and powered it up 
again.  He said that everybody did it all the time -- because the security policies had 
made it impossible for them to do their work otherwise.

The combination of security that ignores users and users that ignore security 
gives you a system that has neither security nor usability.  And simply calling 
users morons will not solve this.

I think a lot of stuff in linux is approaching this complexity/usability 
tipping point, not just in security.  System admin tools, filesystems, logging, 
desktops, etc. have become the playthings of people who like being the chosen 
few who have mastery over

Just out of curiosity, what mail client do you use?  For umpteen zillion years, 
I have been an old-fashioned pine/alpine user, and I'm very happy with it.  But 
the text/ssh thing is getting less and less sufficient.

I normally ssh to a virtual machine I have rented as my mail and web server, 
and read mail in a terminal.  I'm very happy with this, mostly because there's 
little chance I'll accidentally download something bad.  It's hard to pervert 
ascii text.  And, mostly, I don't need to see whatever cute graphics and 
banners people add to their emails -- at least the ones I get.

But... I'm having to deal with images and attachments more and more that I *do* 
want to see.  In order to view the attachment and all I have is pine, I have to 
download it on to the Chicago machine, then sftp it to my laptop, and then open 
it manually.  I have in the past set up vnc to so everything on the server, but 
I'm just not enthusiastic about opening attachments or using a browser on my 
server.  If I open an attachment, I want to do it on my laptop.

So, I set up roundcube on the server, and that allows me to retrieve 
attachments more easily.  I'm reasonably happy with that.

But I've been thinking about setting up a "real" client.  I tried Kmail, and it 
"kinda" worked, but it's hassle factor seemed a bit high.  I have about 15 specialty mail 
addresses (e.g. one each for different professional organizations, addresses for family members, a 
couple of throwaways for shopping, etc), and it seemed that *one* of them always had a glitch in 
KMail.

and since I keep the important data files on a seperate partition the live usb

reinstall. Back up in usually <30 minutes; minus the eye candy.




I didn't used to to that but it has saved my bacon a couple of times, 
especially now that hobbyists like me end up playing around with EFI partitions 
and such.  It's getting all very non-intuitive.

I went out and bought one of those 10-pack 16-gig flash drive packs for 40 
bucks, and a little flash-drive zip-up pouch, and keep a distro on each one -- 
gparted, fedora, manjaro, kali, mint, and tails, and a couple for data through 
a second usb port.

As much as I hear (and say) that "linux is linux," it turns out that, for me, 
different distros are better for different software.  Fedora 23, for instance, is more R 
(the statistical package) friendly than Linux Mint, at least when I try to use it.

One of my colleagues had a cow when he had problems accessing a file on his 
Windows box.  He asked me for help, thinking I would do some sort of Windows 
magic.   Instead, I just booted it up in linux and copied the files.

Which, as a complete off topic thing, I didn't understand.  He was running 
Windows 10, which I *thought* was encrypted by default.  But when I booted the 
box up in Manjaro, everything was sitting right there.  I didn't think it would 
work but I didn't want to spend an hour clicking buttons in Windows, so I tried 
it on a lark.

I'm having the same problem with F23, only with an HP PhotoSmart on

Fedora 23 KDE spin -- Widgets falling through to wrong Activity?

[vendor]

I just installed the Fedora23 KDE spin in a new laptop (HP envy).  It has 
gone great except for a couple of small glitches.  This glitch has to do 
with Activies.


When I create a Widget in an activity, it sometimes disappears when I 
move it, and ends up in a different Activity.  I looked in my

Fedora 23 KDE spin -- no desktop cube?

[vendor]

I just bought me a new laptop (HP envy) and installed Fedora 23 dual boot 
with Win 8.1.  Everything works great, but there are a couple of things 
about the KDE installation that cause me a bit of a disappointment.


1) There's no desktop cube animation option.  Is that a design/deployment 
decision, or is it an installation problem?  Obviously, losing a bit of 
eye-candy is not the end of the world, but I'm a bit dissapointed.


The other is an Activity thing that I'll ask about in a second post, so as 
not to mix topics.


Thanks for any information -- a Google search didn't supply anything.

Some more information.  I noticed that on the compositor settings I can 
only use "XRender".  Every time I try to change it to something else, it 
moves back.  If I set KWIN_COMPOSITE to Q for Wayland (F 23 uses Wayland, 
right?), then I'm allowed to choose OpenGL as the renderer, and it doesn't 
go away.  Then... Desktop Cube Animation option appears -- but just 
doesn't work.  If I set KWIN_COMPOSITE to O, it refuses to accept OpenGL.

If it was me, I'd start with playing with the system settings in my 
windowing system.  I'm a KDE guy. so I go to System Settings -> Input 
Devices -> Mouse and make sure that everything is set right. I'm sure 
GNOME has the same sort of thing.


If you want to go deeper, then you can use

lsusb -- make sure the mouse is there (though it is if only the right 
mouse button isn't working, but what the hell)


If you want to capture usb packets themselves, then wireshark is the way 
to go.  See: https://wiki.wireshark.org/CaptureSetup/USB


But I gotta say, if it's just one button that's not working and the system 
settings thing doesn't fix it, I'd be thinking hardware issues, and I'd 
just spend the five  bucks for a mouse that works.

Re: why do we use systemd?

Unfortunately, the metric for clear explanation is not number of pages.

Have you looked at the manual pages?  I know of no other project that
has the breadth and depth of documentation that systemd has.  Your
statement is, on its face, incorrect.

Re: [OT] Microsoft Bashing

[vendor]

The best article I've ever read on the change at Microsoft was a memoir by 
Joel Spolsky (the Joel on Software blog) written in 2006.  He wrote 
about having to pitch a project to Bill Gates, and how important it was 
that Gates had a technical background.  See:

Hello all,

I was sitting in a dentist's waiting room and I came across this article

I know we all love to hate Microsoft, but after reading this I *almost*
felt sorry for them. I guess many of you know all this, but I found it
quite interesting reading.

Good ammunition for all you Microsoft bashers...

Re: Fedora 18, future isn't too good as it seems :-

[vendor]

Personally, I think the problem is the obsession with regular upgrades to 
new versions on a rigid schedule whether an upgrade is warranted or not, 
not the fact that they're failing in that obsession.  If I have Fedora 17 
installed and things haven't changed so much, then just upgrade the 
existing version.  I'd be just as happy if Fedora 18 didn't come out 
unless the move from 17 to 18 meant some huge functional change -- and 
then I'd be plenty happy if the good folk doing it waited until all the 
bugs were ironed out.  This isn't a commercial system where faux version 
upgrades are necessary to keep up the revenue stream.

Hello,


I'm seeing that Fedora 18 has been delayed 5 times already, and this post
from Michael isn't looking too good either:

Distro like Ubuntu and Suse almost never fails there shipping date, what 
do

you think about Fedora's consecutive delays? Doesn't it hurt it's adoption
rate to end users?




Doesn't really matter from that point of view, Fedora does two
releases a year, one being behind schedule is going to put new
adopters off? They'll just go to the website and get the most recent
version, or off a magazine dvd.

The slippage is a bit worrying, but for other reasons. The discussion
going on seems to be that the process for delaying release doesn't
quite match the reality of what needs to happen. It'll get there, I'd
much rather stuff worked when it was released.

I would think it would better to be a part of the solution than part of the 
problem. We all have something to complain about but how many of us will 
actually get involved with the solution of the problem at hand. It will be 
released when it is ready.

Re: Fedora 18, future isn't too good as it seems :-

Yes, I mean the second.  I appreciate the ability to go in and type yum 
update all the time for all the great bug fixes and such.  It's the 
have-to-do-a-full-version thing on a rigid schedule I don't think is necessary.

Actually regular upgrades are part of Fedora's raison d'être. There's
always a new package or new API that someone wants, or a fix for some
issue. If you want an RPM system that doesn't do regular updates then
go and try RHEL/CentOS/Scientific Linux. I'm not saying 'go away we
don't want you here' I'm saying if that's what someone needs then
those are teh projects that address that.

If what you mean though is the 'rigid schedule' bit, then yes that
seems to be part of the problem. And the move to F18 does mean a big
functional change in the installer, which is what the issue is. It
seems that the work on the installer was inevitably going to take more
time than available in the release cycle, which means the release
needs to slip. No big deal as others have said, but there's no scope
to slip the release by enough time to get it done, so it's been
happening by increments instead, hence the FEDORA RELEASE DELAYED FOR
FIFTH TIME!!! headline. That's not an ideal way of working and it
looks like they are now trying to sort this out. I'm probably
massively oversimplifying here.

Re: No Music or Movies Play in F17 - Missing Gstreamer?....

[vendor]

My solution is completely empirical -- having had it work a few times in 
the past.  Whenever I have had problems with codecs and such, I install 
mplayer and ffmpeg and all the files yum drags in with it.  That seems to 
fix the problem about 90% of the time...

Try installing these. You may have to install repository files for rpmfusion 
which you can easily get from the net from their site.

lame-mp3x gstreamer-plugins-bad-free-extras gstreamer-plugins-ugly  mpg123 
mpg123-plugins-extras 
mpg123-plugins-jackmpg123-plugins-pulseaudio mpg321 gstreamer-plugins-bad-free-extras gstreamer-plugins-fc gstreamer-ffmpeg  gstreamer-plugins-ugly gstreamer-plugins-bad-free gstreamer-plug
ins-bad gstreamer-plugins-bad-nonfree gstreamer-plugins-good gstreamer-plugins-entrans

Some of the packs  mentioned may already be installed. Yum will simply skip 
them. Some I may have posted more than once, so excuse that.

These are meta packs which pull in lots of decoders, plugins etc.

DVDAuthorWizard DVDRipOMatic

You can also install these packs for multimedia.

mozilla-vlc  vlc-plugin-jack vlc-extras vlc ffmpeg2dirac ffmpeg2theora 
dirac mp3gain 
libtunepimp-extras-freeworld 

Install flash-plugin from adobe.

Some packs may be redundant but they are small  also don't hurt anyone.

Newbie question abt network install

[vendor]

Sorry if this is the wrong forum -- if it is, please direct me to the 
right one.


I rent a virtual personal server in another city that runs Fedora 16.  I 
want to upgrade it to 17.  I did the yum-based preupgrade and such, but am 
stuck.  The instructions I read said to reboot and then choose upgrade at 
the boot screen.


Since this is a network machine that has no boot screen, I need to tell 
the box to upgrade in some other way.


Is there a way to to a yum upgrade over the network without seeing a boot 
screen?


Thanks!

Re: Newbie question abt network install

I did -- he said that it was my responsibility to upgrade the virtual 
machine.  The service they would provide would only be a reinstall of the 
image of Fedora 16.  The bottom line is that I'm give a virtual box and 5 
static ips, and all maintenance is my responsibility.

Since you rent this, it's not yours to upgrade.  Consult the owner of the 
machine!
