Put a script in /etc/xdg/autostart or ~/.config/autostart to

serial port woes

2021-01-15 Thread Dr. Michael J. Chudobiak

  
  
Hi all,
If I install the moserial rpm from the repos, I can communicate
  with a serial device on /dev/ttyS0 just fine.
However, if I remove the rpm, and compile it from source, the
  program launches and connects to /dev/ttyS0 (as reported by lsof),
  but data transmission doesn't happen.
What could possibly explain the difference between the rpm
  version and the locally compiled version? Same code, but maybe
  different build flags? What would affect the serial port?

I can communicate with the remote device using minicom or tio
  (using their rpms).

selinux is disabled.

problem with personal default printers?

2019-09-11 Thread Dr. Michael J. Chudobiak

  
  
My F30 systems have recently developed problems... some programs
  use the "system-wide default printer", instead of the "personal
  default printer", as set in "Print Settings".
Thunderbird and Firefox and LibreOffice have all started
  (incorrectly) using the system-wide default as the default
  printer, ignoring the personal override.

gedit and gimp correctly use the "personal" default printer.
I'm not seeing this in bug reports anywhere... Anyone else run
  into this?
All my printers are accessed through a single cups server.

Re: Puppet in Fedora 22 working?

2015-07-06 Thread Dr. Michael J. Chudobiak

I was away from my installation for 6 months. I came back and upgraded
to Fedora 22 (as Fedora 20/21 was giving me problems with FreeSWITCH and
other things). After doing so I find that Puppet does not work. It
doesn't seem to find any of the hiera (yaml and json backends) defined
nodes get their catalog (they get one, but without the classes they
should have) at all.

Has anyone seen this? Any suggestions on how to go about remedying the
problem?


Probably this:

I have puppet working on F22 after making the hacks noted in the bug 
comments.

Installing the nscd caching name server seems to cut the delays

gnome-shell: slow logins?

2015-03-10 Thread Dr. Michael J. Chudobiak
I have a variety of F21 users, some with remote home folders (on 
gluster) and some with local home folders (on desktop SSDs).


Some users experience login delays on 30-60 seconds after entering their 
username/passwd in gdm (the "last login" time is shown, so it is not an 
authentication delay). The gnome-shell background does not appear during 
that delay.


What causes these delays? How can I debug it? I tried masking the colord 
daemon, and moving the tracker files out of /etc/xdg/autostart/, but it 
didn't help.


Logouts can be painfully slow too.

Some systems are super-quick to load, so it's baffling...

Any ideas?

onboard NIC not working after upgrade

2015-01-08 Thread Dr. Michael J. Chudobiak

Hi,

My onboard intel ethernet NIC (em1, e1000e driver) in my HP DC7800 no 
longer works after the upgrade to F21. It worked fine before. Inserting 
a PCI NIC (p3p1, e1000 driver) restores network functionality.


The link lights for the onboard NIC are on during the bios bootup, but 
go dark very early during the linux boot.


I don't really see anything interesting in the logs (I've grepped for 
e1000 below. Any suggestions? lshw says the onboard nic is "DISABLED". 
Why? ethtool says there is no link.

Re: So acrobat is dead for linux - long live evince?

2014-12-17 Thread Dr. Michael J. Chudobiak

MasterPdfEditor is horribly slow to display my pdfs, which contain matplotlib
pdfs with thousands of data points.  evince is very fast at this.



evince chokes on PDF files with heavy bitmap-image content, like dense 
city GIS maps. (Probably due to poorly-implemented scaling internally; 
gtk routines don't do scaling well.) okular handles them fine.


You have to pick-and-choose linux PDF readers depending on the 
application, unfortunately.

IIUC, GNOME overrides the system-wide locale settings with it own
values, by default it's en_US.utf-8; there are two bits that affect the

the value of the gsettings key 'org.gnome.system.locale region' (note
that the same value is set for LC_NUMERIC, LC_TIME, LC_MONETARY,
LC_PAPER, LC_MEASUREMENT).

You can change the default for all users using the following steps:
- Create
/usr/share/glib-2.0/schemas/org.gnome.system.locale.gschema.override and
put this in it:
[org.gnome.system.locale]
region='en_DK.utf8'

- As root execute:

Check the AuthorizedKeysFile setting in /etc/ssh/sshd_config, on both

.ssh/authorized_keys

and one might be using

Re: what's the point of filing bugs against Fedora?

I filed a bug (1040518) against the Mate desktop, and was told to ask
upstream for help because they can help me.  I don't understand this.  I
installed Mate from the Fedora DVD and I therefore expect the Fedora
engineers to act as buffer between me and upstream.  It should be their
responsibility to work with the Mate engineers, not mine.


FOSS bug triaging is a slow, time-consuming process that relies on 
interested VOLUNTEERS.


Someone has triaged your bug report, and advised you of the best place 
to obtain support from the actual developers. Take the advice and report 
the bug where the developers are most likely to see your report and respond.


It is not always clear where the best place to report a particular bug 
is. Luckily, someone has taken the time to tell you.


The fedora bugzilla is generally best for packaging issues (e.g., 
missing dependencies, version X of foo broke version Y of bar). Upstream 
bugzillas are better for reports of program flaws.




I've done tech support for Linux for many years.  Do you know how long I
would have lasted if I told one of my customers


You aren't a Fedora customer. You are a Fedora user.

Re: Why some say "rpm hell"

Well I just heard a couple of guys saying "rpm hell".

Now a days, when rpm works very well, still does it lag behind apt in
some ways...?


yum didn't always exist. yum handles the dependencies between packages. 
Before that, a lot of prayer was involved if you mixed rpm packages from 
different sources.

Thunderbird unread message count

2013-10-16 Thread Dr. Michael J. Chudobiak
Has anyone else had problems with Thunderbird showing incorrect 
unread-message counts on IMAP folders since the last TB update (in the 
past week or so)?


I don't see any bugs reported on it in the Fedora bugzilla.

I'm using dovecot as the IMAP server.

Deleting the TB *.msf files on the client, and the dovecot* index files 
on the server, did not help.

need help printing UPS shipping labels

2013-08-14 Thread Dr. Michael J. Chudobiak
Does anyone here successfully print UPS shipping labels from the UPS 
online shipping tool?


I find that when I try this with Firefox, epiphany, or Chrome on F19, 
the barcode-containing section of the label is generated as a 728x416 image.


If I use Firefox or IE on Windows, the same label is generated as a 
1400x800 image.


The UPS scanners won't recognize the barcodes in the smaller images, so 
I have to print from Windows.


Any ideas? Is this some odd javascript default-image size setting that 
differs with OS?

Re: F17: How to set up VPN for Android?

2013-03-26 Thread Dr. Michael J. Chudobiak

I use ssh tunnels to forward Android imap (port 143), smtp (port 25),
and http proxying (port 3128) to my Fedora server, using this app:


What do you use as a proxy on the Fedora server? glype? squid?

On the android you configure a proxy for each browser? Or does SPT just
send all port 80 requests to the server?

Any details on the config would be very helpful.


Install the SPT app & forward local ports 1043, 1125, and 3128 to remote 
143 (imap), 25 (smtp), 3128 (squid proxy).


In my case, SPT Forwards = 
"L1043=192.168.0.2:143,L1125=192.168.0.2:25,L3128=192.168.0.2:3128"


Here, 192.168.0.2 is the internal address of my server (not its external 
IP).


The forwarded local ports need to be > 1024, IIRC.

You point the email client at localhost for the SMTP/IMAP, using the 
special local forwarding ports 1043 and 1125.


For web use, I use Firefox, and in about:config set:

network.proxy.type = 2
network.proxy.autoconfig_url = http://www.avtechpulse.com/proxy/avtech.pac

That *.pac file says:

function FindProxyForURL(url, host) {
if (shExpMatch(host, "*.domain.avtechpulse.com"))
{
return "PROXY 127.0.0.1:3128";
}

return "DIRECT";
}

That means squid serves the private intranet pages from the private 
squid server, and firefox accesses all other pages in the normal manner 
(not through squid).


Firefox is the only browser that handles this proxy trickery well.

Sounds complicated, but works like a charm.

I use ssh tunnels to forward Android imap (port 143), smtp (port 25),

The main gotcha is that each tablet needs its own dedicated ssh port, so 
that the office NAT/firewall/router can keep track of ssh sessions 
correctly. But that is easy to implement, for a handful of devices.


It works quite well for my needs.

upgrading with preupgrade-cli --vnc

2012-05-30 Thread Dr. Michael J. Chudobiak

Hi all,

What grub2 secret sauce do I need to upgrade remote servers to F17 using 
vnc?


This is the first step, clearly:

preupgrade-cli --vnc=apassword --ip=192.168.0.240 
--gateway=192.168.0.128 --netmask=255.255.255.0 --dns=192.168.0.2 
"Fedora 17 (Beefy Miracle)"


However, this installs the upgrade boot menu item as a non-default item. 
In other words, by default it will boot back into F16 without doing the 
upgrade.


What's the correct way of forcing the upgrade choice in the grub2 menu 
to be the default, so I don't need a local user at the console?


I edited /etc/default/grub, setting grub2_default to "0", and ran:

grub2-mkconfig -o /boot/grub2/grub.cfg

but that wiped out the upgrade choice entirely. Not sure why.

I don't think the preupgrade-cli docs have caught up with grub2.

The thread contains an extensive troubleshooting discussion of how to get
rc.local functionality working.  There are quite a few things to check and the
thread covers most of them.


The OP had a typo. He was using "rc.local.service" instead of 
"rc-local.service". Fixing that fixed his problem.

It should be "rc-local.service", not "rc.local.service". Like this:

[root@xena ~]# systemctl -a | grep rc-local
rc-local.service  loaded active   running

Yes, or provide separate openvpn-server.service and

Re: Fedora disimprovements: am I alone?

2012-03-23 Thread Dr. Michael J. Chudobiak

How they were started does not seem to have much to do with chkconfig.


The init system used a series of hard-coded numbers in the init scripts 
to judge which services were to be started in which sequence, which was 
a horrible mess.


You had to make sure the service X's priority of 37 was in between 
service Y'x priority of 18 and service Z's priority of 56.


With systemd, you just say things like:

After=syslog.target network.target auditd.service
and/or
Before=poweroff.service reboot.service halt.service

Which is MUCH more concise and easy to understand. The computer figures 
it all out, instead of the user having to juggle priority levels.


Also, all init scripts with priorities > 37 would all have to wait for 
the "service X" to finish. This is not so with systemd. The service 
files specify the minimum dependencies. If service Z does not require 
service X, it can go ahead, even if service X gets delayed.


See?

The CLI syntax is different, but the difference is negligible once you

However, the *.service file syntax is much, MUCH simpler than the old

An old-style postgrey init script:
http://lists.puremagic.com/pipermail/greylist-users/2006-May/001208.html

A new-style postgrey service file:
http://bugzilla.redhat.com/show_bug.cgi?id=714430#c10

There is way less wonky bash scripting in the new service file, because 
it is mostly declarations, rather than code. As an added bonus, the old 
postgrey init script never worked properly for me (it did not kill 
cleanly, no idea why), but the new systemd service file works great.


For example, if you declare the name of the pid file in the service 
file, systemd automatically knows to use that pid when stopping the 
service. It's brilliant.

I'd agree that the systemctl syntax is clumsier. But on my machines,
the boot time has reduced dramatically.


I still haven't discovered the equivalent of "chkconfig openvpn on"
under the new dispensation.


openvpn has special issues with systemd, but once you know the magic 
recipe, it works fine. See:

https://bugzilla.redhat.com/show_bug.cgi?id=744244

If your openvpn config file is /etc/openvpn/client.conf, do:


ln -s /lib/systemd/system/openvpn\@.service \
   /etc/systemd/system/openvpn\@client.service

systemctl daemon-reload

systemctl start openvpn@client.service

systemctl status openvpn@client.service


Replace "client" with "server" in each command if the computer is the 
openvpn server.

Never mind. I've figured out that the Galaxy Nexus does in fact have a

The default MTP mode seems to be totally broken under linux.

For other Galaxy Nexus users: after plugging in the USB cable, "swoosh"

importing photos from Galaxy Nexus Android phone?

2012-03-12 Thread Dr. Michael J. Chudobiak

Hi all,

Has anyone found a successful, reliable recipe for importing photos from 
a Galaxy Nexus Android phone?


I find that F16 does not do anything with the phone when it is plugged 
into the USB port. The kernel recognizes it, and gphoto2 can access it, 
but nothing happens automatically.


I can force gvfs to mount the phone using:

gvfs-mount "gphoto2://[usb:001,003]/"
(using the usb address shown by lsusb)

With it mounted, gThumb sees the device (it relies on gvfs), and it can 
import the photos.


Other cameras work OK, so the gvfs/gphoto2 subsystem is working.

My bug report: https://bugzilla.gnome.org/show_bug.cgi?id=671906

Any clues?

/etc/passwd is world-readable, and contains the basic account info (id,

/etc/shadow is root-only-readable, and contains the password info.

They are separate to improve security.

They are not backups. Those are the main files for local authentication.

I'm wondering if it was pushed into Fedora too soon. Of course, Fedora's
a test-bed for new things, but I'm not sure systemd was ready for such a
wide-spread beta test. If anybody happens to have a link to an
explanation of what's so much better about systemd I'd be glad to follow
it and learn, but it's not urgent enough for me to go hunting and
weeding out all of the blind leads.


http://0pointer.de/blog/projects/why.html summarizes it pretty well.

I found the old style of unit scripts to be a pain in the ass. I'm not 
sure why people think it was so great.


And "systemd-analyze plot > plot.svg; eog plot.svg" is the best tool ever...

   but this must be redone whenever a new update comes along.


That's been an issue for a long time, well before F16 - are you using nfsv3?

I think open/libre-office work directly with nfsv4 (could be wrong).

However, I found nfsv4 to be unusable as a home-folder-server in F16 - 
it was a huge source of instability. gluster is problematic too in F16. 
I've settled on moosefs as a file server. It works extremely well with

Does your /etc/default/grub file have "nomodeset" in it?

Yes, that's what I meant. Unfortunately, it seems your system needs 
"nomodeset" to boot - I guess the installer detected that and put it 
there on purpose. (On my systems, it was put there, but it wasn't 
actually needed.)

If you want the main gnome-shell mode, you need:

1) A better video driver.
or
2) A different video card.
or
3) Wait for F17, which is supposed to run gnome-shell on a wider range 
of video cards - but the performance might be poor.

Check your /etc/default/grub file, and make sure that "nomodeset" is not 
in it. I found this was in some of my /etc/default/grub files, because I 
had selected a basic text upgrade mode when running anaconda. This made 
the upgrades run faster, but it disabled the fancy graphics modes than 
gnome-shell needs.

If it is there, try removing the "nomodeset" clause and regenerate your 
grub files by running:

grub2-mkconfig -o /boot/grub2/grub.cfg

enabling gnome-shell extensions system-wide?

2011-11-14 Thread Dr. Michael J. Chudobiak
It seems that gnome-shell extensions are not enabled by default in 
gnome-shell 3.2, even if you install the appropriate rpm.

Is there a command-line method of enabling all installed extensions for 
all users?

It's a bit cumbersome to run gsettings commands for every user on every 
system, or similarly use gnome-tweak-tool. A system-wide switch would be 
helpful.

It's simple; it works. I was following various recipes collected from 
the web.

Also, I had a problem starting the management service (which provides 
the CLI functionality), so I couldn't use the CLI tools. I don't recall 
the exact problem now.

I guess you can configure things "statically" from the config files, or 
"dynamically" from the CLI. I like the config file approach, personally.

A usable fork of gnome2 will NEVER happen. People who think it will have 
no idea of the size of the gnome project and related gtk-based projects. 
Are they going to set up new source code repos? A new bugzilla? New 
translation teams? A new release team? A new set of core developers 
actually adding new code? Will other gtk-based projects (like my serial 
terminal program, moserial) release gtk2 and gtk3 variants?

However, gnome-shell is heavily customizable through extensions. If 
people want a gnome2-ish experience, they would be better off writing 
extensions to mimic the gnome2 experience. Some already exist, of course.

I personally like gnome-shell. I can only conclude that people who don't 
are bad people. People who kill kittens. Shame on you!

glusterfs and nfs mix nicely - you can use the native glusterfs client 
(I do), or you can use an nfs client to access the glusterfs server.

You can export a folder using both an nfs server and a glusterfs server 
at the same time, which is nice for a gradual migration.

I use glusterfs over openvpn + cable modem, and it seems much more 
responsive than nfs ever was (judged using "ls -l"). But I haven't 
benchmarked it objectively.

I'm not sure about that...

Anyway... it sure solved a lot of stability problems for me. glusterfs

I found NFSv4 to be completely unusable on my F14 systems. I could never 
figure out where the problem was. It was unusable on my F14 clients when 
I had a F13 server, and once I upgraded the server to F14, my F13 
clients became unusable...

In desperation, I had to move to glusterfs, which fixed all my problems:

http://www.mail-archive.com/users@lists.fedoraproject.org/msg40298.html

I've been very happy with it since the forced migration! It has a lot 
fewer oddities than NFS, and it handles sqlite/firefox file-locking just 
fine, unlike some (all?) NFS variants.

Well, the developers did say they liked the idea, but they didn't have

I've run into similar frustrations, but I've had good experiences hiring 
coders on www.vworker.com to develop patches for not-that-much 
money-wise. (An example: 5 years ago, I wanted gThumb to be able to 
print the full path and filename under a printed photo. $200 got me the 
patch I needed, and I submitted it for inclusion in gThumb. It was 
accepted. Another $200 got a redeye-removal tool into gThumb.)

If you don't want to use DNS, you can share /etc/hosts using NIS. Look 
in /etc/nsswitch.conf. I don't think it is any simpler than using DNS, 
however. You need to set up ypbind/ypserv... however, if you are using 
NIS to authenticate users already, then it is trivial.

keychain/ssh-agent problems

2011-09-19 Thread Dr. Michael J. Chudobiak
Hi all,

I've been using keychain and ssh-agent for years, but it somehow has 
become flaky on F15.

I have this in .bash_profile:

keychain ~/.ssh/id_dsa
. ~/.keychain/${HOSTNAME}-sh


Normally this works fine, except when ssh-agent randomly seems to die, 
like this:


[root@server2 ~]# su - webmaster

KeyChain 2.6.8; http://www.gentoo.org/proj/en/keychain/
Copyright 2002-2004 Gentoo Foundation; Distributed under the GPL

  * Found existing ssh-agent (13894)
  * Found existing gpg-agent (13921)
  * Adding 1 ssh key(s)...
Could not open a connection to your authentication agent.
  * Error: Problem adding; giving up

[webmaster@server2 ~]$ kill 13894


Logging in again (to re-run keychain) works OK after that.

Any ideas what the issue might be?

Fedora 15: a NFSv4 to glusterfs migration HOW-TO

2011-08-25 Thread Dr. Michael J. Chudobiak
As detailed in another thread, we upgraded a few test machines on our 
LAN to Fedora 15 (with gnome-shell and firefox), with user folders 
served from a NFSv4 server (F14 originally, then F15).

It just didn't work. The F15 desktops would freeze frequently. And 
worse, this would freeze ALL desktops on the LAN intermittently, as the 
NFS server struggled with client flakiness.

When it did work, Firefox would lose authenticated logins randomly, 
presumably due to corruption of its cookies.sqlite file. sqlite and NFS 
seems to be a nightmare, for both NFSv3 and NFSv4.

Moving from a NFSv4 server to a glusterfs server solved all of these 
problems, and sped up boot times significantly too. glusterfs looks 
intimidating at first, because of all its fancy replicating features and 
what-not, but it turns out to be trivially easy to set up a simple 
server than will replace 95% of the NFS installations out there.

Luckily, you can easily point both the NFS daemon and the glusterfs 
daemon at the same export folder, so you can migrate clients slowly over 
time.

This HOW-TO is intended to document the process. There are other similar 
HOW-TOs out there, but they are all a little out-of-date or don't show 
how to enable locking correctly, which is critical for Firefox.

In this example, we export the server's /fileserver folder, and mount it 
on /fileserver on the clients. In my server, /fileserver was already 
being served by the NFSv4 server, which is fine.


1. On the server:
- yum install glusterfs-server


2. On each client:
- yum install glusterfs-fuse
- mkdir /etc/glusterfs/
- mkdir /fileserver


3. On the server, edit the volume configuration file
(/etc/glusterfs/glusterfsd.vol) so that it looks like this:

volume raw
   type storage/posix
   option directory /fileserver
end-volume

volume brick
   type features/posix-locks
   subvolumes raw
end-volume

volume server
   type protocol/server
   option transport-type tcp
   subvolumes brick
   option auth.addr.brick.allow *
end-volume


The first stanza selects the basic folder to export.

The second stanza adds file locking to it. This is required to support 
Firefox, and some other applications.

The third stanza authorizes everyone to access this file-locked export 
over the network.

There is also a /etc/glusterfs/glusterfsd.vol file on the system, for 
configuring the management interface. For this simple installation it 
does not need to be modified.


4. Restart the server services:
- service glusterd restart
- service glusterfsd restart

I believe the first service is a management service, and the second is 
the actual file-export service.



5. On the client, create the /etc/glusterfs/glusterfs.vol configuration 
file, which should look like this:

volume client
   type protocol/client
   option transport-type tcp
   option remote-host 192.168.0.3  # use YOUR server IP here
   option remote-subvolume brick
end-volume



6. On the client, add this line to the end of /etc/rc.d/rc.local:

mount -t glusterfs /etc/glusterfs/glusterfs.vol /fileserver


7. On the client, reboot, and check /var/log/messages for errors. On one 
machine, we had an selinux problem that was flagged in the logs. We had 
to manually create the logging file using:

touch /var/log/glusterfs/fileserver.log; reboot


8. On the client, see if you can access the files in /fileserver. If 
not, read the /var/log/glusterfs/* files on both the client and the server.

At this point, everything should work!



Weird things and gotchas:

A. You need the file-locking option to make Firefox work properly.

B. LibreOffice wouldn't start on one system, until we did:
rm ~/.libreoffice
rm ~/.openoffice.org

C. selinux prevented the creation of log files on one client, which 
prevented the filesystem from mouting. The manual fix noted above fixed 
that.

D. This HOWTO mounts the glusterfs from /etc/rc.d/rc.local, which is the 
last step in the boot process. In theory, you can mount it from 
/etc/fstab or using autofs. However, we found that autofs mounting just 
didn't work - not sure why. fstab mounting didn't work either - I 
suspect it occurred too early in the boot process. /etc needs to be up 
and running so glusterfs can read the config file, and I don't think the 
current init/systemd files handle this correctly. There are some Debian 
bug reports about this that you can google.


I hope this is useful to someone, and that we can finally drive a stake 
through the heart of NFS...

OK, gnome-shell + firefox + nfsv4 = JUST DOESN'T WORK.

I switched to glusterfs, and with a few tweaks, it rocks! (Tweaks = need 
"features/posix-locks" in glusterfsd configs, and do the client mounts 
in /etc/rc.d/rc.local, and not in /etc/fstab.)

My firefox freezes are gone. Firefox has stopped losing my authenticated 
sessions (cookies.sqlite). The system boots much faster.

I hope this helps others in a similar situation!

I have "no_root_squash" on the nfsv4 server, so it isn't that bug... but 
thanks for the pointer anyway.

gnome-shell + nfsv4 = problems?!

2011-08-22 Thread Dr. Michael J. Chudobiak
Hi all,

I've been testing F15/gnome-shell on my desktop, and it works great... 
except when I install it on a second user's desktop, everything slows to 
a crawl, sometimes freezing the shells altogether. I can tell when 
another gnome-shell system is in use, because mine freezes!

All users have nfsv4-mounted home folders on an F15 server. The systems 
are acting like network problems are happening. If I Ctrl+F2 to a text 
console, the local system is responsive, but directory listings of 
remote folders are sluggish.

I don't see useful info in the logs.

However, ifconfig DOES show dropped RX packets on both systems, as well 
as the server. All systems use the e1000e driver.

The systems are connected through a variety of switches, so I don't 
think it is a switch issue. The F14 systems seem to work OK.

Anybody heard of something similar?

- Mike

I have a couple of F15 desktops running Windows XP guests. I start them 
using root cron:

@reboot sleep 30; /usr/bin/qemu-kvm -hda 
/var/lib/libvirt/images/MikeWindows.img -usbdevice tablet -m 2048 -k 
en-us -vga qxl -spice port=5930,disable-ticketing &

I found this was simpler than relying on virt-manager, especially when 
you want to move images to new machines.

Spice is a dramatic improvement over the older vnc-based methods. I love 
it...

Luckily, gnome-shell works with most video cards, so you don't have to 
rewrite the linux desktop.

However, if you have more than a few desktops to maintain, it's usually 
worthwhile have spare video cards (and spare network cards) around. 
Fedora has the cutting-edge drivers. "Cutting edge" isn't the same as 
"works every time"...

Maybe try another video card (one that uses a different driver).

I haven't experienced ANY crashes of gnome-shell, on 3 test desktops, so 
a stable system is possible.

You can still minimize apps - right-click on the title bar, and click 
"minimize". (Or use the tweak tool to re-enable the buttons.)

However, I use the mouse-swoosh to switch between active windows. It is 
quite workable, for me, and after a while it seems quite natural. I 
don't find that it takes any more effort than gnome2-style minimizing 
and panel-clicking - less, actually.

But, use whatever works for you!

You can also right-click on the title bar, and minimize is the first 
choice. It's "almost" as easy as a dedicated button, once you're aware 
of it.

I originally thought omitting the minimize button was crazy, but after 
using gnome3 for a month or so, I don't miss it at all. gnome3 has a 
different way of doing things; give it time. If you can "swoosh" into 
the activities area to rapidly select a different window, having a 
minimize button doesn't really make sense (or at least, it is redundant 
- and gnome has always opted for simplification over extra flexibility).

I also originally hated the default fonts, but I like them now - but I 
had to enable "Large Text" in the Accessibility button at the top.

I'm not sure about the task-switching method, though. I'm having a hard 
time using the alt+tab / alt+backtick combo naturally. I think it could 
be improved.

My 2 cents.

I see text corruption in gnome-shell too, sometimes. I'm not aware of a

Wait. Maybe for an hour, or overnight if you can.

I gave up on some upgrades, before I realized that the blinking-cursor 
screen does disappear after ~ 5 minutes (for me), and the upgrade 
continues just fine. Others have reported longer delays.

I've done 2 desktop upgrades. One worked fine. One had the problems you 
described (frequent freezes), so I had to downgrade it back to F14.

Three server upgrades have gone well, but they don't have gnome3, of course.

Not very helpful, but another data point anyway...

I don't know how to do that at the command line, but you could try using 
moserial instead.

Linux isn't Unix. It sounds like you'd be happier running, er, Unix - or 
a BSD - rather than a Linux distro that is considered to be the most 
cutting-edge one available.

Management? Who's that? FOSS "management" mostly falls to the 
developers, since they're doing the work.

But regardless who you choose to identify as management, you'll probably 
find that they've been very supportive of systemd, mostly because it 
solves lots of real-world problems in an elegant way. Sure, there have 
been glitches (and squabbles about timing - systemd punted from F14), 
but again, this is a running-with-scissors distro.

Personally, I'm hugely impressed with the sped-up boot and shutdown 
times, and the detailed reporting (did something fail?) provided by 
systemctl.

Fedora is lucky to have flame-proof developers like LP who aren't afraid 
to try something new...
