Machine locks on reboot from suspend
I have a Dell Precision 5820 Xeon with nVidia GeForce GT 1030 graphics for video and a Quadro 4000 that I was playing with for GPU algorithms. I have a fresh (fully updated) install of Fedora 39 with the nouveau driver. When I resume from suspend, no video shows. I can still ssh to the machine, though. If I issue 'sudo shutdown -r now' from an ssh session, the machine freezes. I can still ping, but I can't ssh (connection refused errors). The only way I can regain control of the machine is to power down by holding down the button on the front of the machine and start from cold. The proprietary nVidia driver doesn't exhibit the same problem. In addition to the above, this machine has a problem where on boot, it doesn't show the menu with kernels to select from. It displays "booting in insecure mode", then goes directly to booting with the latest kernel. I haven't changed any grub options since the install and I don't have this problem on any other machine I use. I can get the menu with ESC, but I can't figure out why it doesn't display by default. By now, I do have two kernels installed. Any thoughts on a solution? For the first problem, I'm not sure what component to report on in Bugzilla.

Remote desktop on headless server?
Hi, all- I would like to set up a workstation in a network closet with no monitor or keyboard attached and run a (GNOME shell) desktop session from another machine on the local network. What's the best way to do that in Fedora 38, and is there a good source of documentation someplace? The GNOME desktop sharing facility requires that the connection be to an active session logged in on the console. Googling hasn't been much help for recent distros.

F35 install doesn't find existing Windows installation
I have a Lenovo Yoga X1 (2nd generation), on which I was happily running a dual boot of the original Windows 10 installation that came with the machine and Fedora 34, which I had upgraded through a few versions of Fedora. This time, I decided to do a fresh install of Fedora 35 (to try out BTRFS), but when the installation finished, there was no option to boot Windows. The Windows data partition, Microsoft reserved partition, and recovery partitions are all still in place. I attempted to use grub- customizer to add a chainloader entry pointing to the Windows, but it displays "Error building boot sequence. Check parameters!" Gparted shows the Windows partition and the EFI partitio both have bootable and esp flags set. Thanks in advance!

Since I sent this, the behavior has been consistent: auto-rotation doesn't work in Wayland and the rotation lock icon in the system menu doesn't appear.

Wacom Bamboo Ink?
Has anyone used a Bamboo Ink or Ink Plus stylus with Fedora? Fedora 31, up to date. Lenovo Yoga X1 second generation. Trying to use a Bamboo Ink Plus stylus. I can pair it via Bluetooth, but I can't get it to connect after pairing. When I attempt to connect, the Bluetooth connection dialog window spinner runs for several seconds, then indicates the connection is off. Any advice about things to install to support this device would be much appreciated. If the Ink Plus can't be made to work, I can downgrade to the Ink. If anyone has a better suggestion for a full-sized stylus, I'd welcome that too. The built-in Yoga stylus works fine, but it's not comfortable for significant pen work.

IIRC, for GNOME, Wayland is the default and firefox-wayland is the default. You can install and run firefox-x11 even when running Wayland, but someone else might be able to say whether the reverse is true. For other desktops, firefox-x11 is the default and if running Wayland, you can install firefox-wayland. As I've been using it, firefox-wayland appears to have a pretty severe memory leak, at least when many tabs are open--eventually, it starts to spill into swap space. Restarting Firefox mostly clears the problem, for a while. I haven't tested much with firefox-x11, though. Also, when I first started running F31, firefox-wayland used a bunch of processor even when I wasn't doing anything. That seems to have settled down, though. Not sure if it's just some tab I closed or what, but that was a behavior change from the version in F30. > > I am confused -- Matthew Saltzman School of Mathematical and Statistical Sciences Clemson University mjs AT clemson DOT edu ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org

Eclipse and Fedora 30 upgrade issue
Is there a workaround for the issue where the Fedora 30 upgrade decides that all of Eclipse is not compatible with Fedora 30 and removes the complete collection of Eclipse packages?

Redshift and Dropbox not quite working after F24-F25 upgrade
I have two GNOME workstations upgraded from F24 to F25. Before the upgrade, Dropbox and Redshift were accessible from the little slide-out task bar at the lower left of the screen. Now, on one I see Dropbox but not Redshift and on the other, I don't have the slide-out drawer at all. According to GNOME Tweak-Tool, both apps are listed on the startup panel. So far, everything else seems to have gone smoothly. How to debug?

You can think of moving the window over the page (the way we are mostly

Sorry, missed seeing Ed Greshko's response. I guess that, unfortunately, GNOME Shell no longer supports setting those in Mouse Settings or Tweak Tool, or even anywhere in dconf.

OK, thanks. I checked and the current settings are the ones I want (and presumably set at some point in the past): scroll-method is 'edge- scrolling' and tap-to-click is true, but that's not how the touchpad is behaving. In dconf-editor, there's a comment next to the scroll-method setting that says "No schema found". Also, the lines for scroll-method and tap- to-click are in bold-face type. I guess that means they are not at their default values. Also, there is a setting for edge-scrolling- enabled, and it is set to true.

Fedora 24 touchpad customization
It seems that some of the touchpad customization options that were available previously have been removed in Fedora 24. In particular, two-finger scrolling is enabled by default, but edge scrolling is not available. Also, tap-to-click is disabled by default. Neither the Mouse Settings app nor Tweak-Tool have options to change those settings. Is there a manual way to set those options with dconf-editor or some other tool?

nVidia Optimus support status
Apparently, the latest release of Bumblebee has dropped support for the nouveau driver. Installing the latest primus package from the bumblebee repo requires removing bumblebee-nouveau and installing bumblebee- nvidia. I haven't seen an announcement to that effect, but there is a bug report at the Bumblebee repo suggesting that that's the direction they are going. Is there a good, up to date summary of the state of Optimus support for Linux and Fedora, both open-source and proprietary? Anyone have in- depth experience with Dell (Latitude E6430) implementation and a recommendation for the best way to proceed?

Note that it worked for a time before failing, so the API key should have been good. Set the URL protocol to https and it worked with my API key.

openweather GNOME plugin and forecast.io
My issue is the reverse of the thread about openweathermap.org. Openweathermap.org is working fine for me in the OpenWeather GNOME plugin, but if I switch to forecast.io, nothing loads. This used to work fine a couple of months ago, but now it fails on multiple machines. I have API keys for both sources and I can log into both from a browser. I find the forecast.io reports more accurate than openweathermap.org, so I'd prefer to switch, if I could get it working again. Any suggestions or related experiences?

USB drive renamed during F21-F22 upgrade
It looks as though when I upgraded from F21 Server to F22 Server using fedup, the identifier for my USB attached drive in /dev/disk/by-id changed. As a result, the entry in /etc/fstab that mounted that drive failed at boot with no apparent warning. Files intended to be written to that drive went to / instead and filled the root partition. I don't recall why that disk was mounted by id in the first place, but I also don't understand why its id would change and how I should have handled that during the upgrade. Any thoughts, enlightenment, etc., appreciated. Also, what's the right way to set up automounting on a server that doesn't run a desktop environment? -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Not sure why it doesn't work in ssl.mod or how I was supposed to figure it out, but at least now it's working.

Displayport/HDMI sound output channels reversed
I have a Dell Latitude E6410 (running up-to-date F20 and the nvidia display driver) with a displayport alternate video output. I use a displayport-HDMI converter to run videos to a TV screen. When I configure sound to play through the displayport/HDMI output, the left and right channels are reversed. Running the sound setup tool, I test the speakers and the left speaker test plays through the right speaker and vice versa. Anybody else seen this? Is there a setting that can be changed someplace? Or is this a bug? Or both?

This will change the value of the pixel in question. Let's say that this process involves 500 high-level instructions. 3) Move to the next pixel. Do the same thing. If you have a 12-megapixel image (say, 11,760,000 pixels), that's 5,880,000,000 instructions. That 500 instruction block is impossible to parallelize well. However, each pixel is independent, so you can parallelize the work on each pixel easily. I remember back in the 80s implementing this on a microVAX GPX II. It took about 3 hours to do a 512x512 greyscale image by brute force. Then Henry Fuchs et al. developed the PixelPlanes machine, and Austin et al. implemented it on that -- it took about 4 seconds. Even today on my laptop with an i7, a brute-force contrast-limited adaptive histogram equalization on a 10 megapixel image takes a go get a cup of coffe time period. There are, of course, short cuts such as the Pizer-Cromartie algorithm, but they introduce interpolation artifacts. Sure, that's a good example of something that could benefit from parallel processing. But you still have to be careful. For instance, suppose you do have two different processors working on adjacent pixels in parallel. At some point, one of the pixels will be modified first. Depending on exactly when that happens, it can affect the final value of the second pixel, depending on whether the original or modified value of the first pixel is fetched when calculating the second. If done blindly, without any locking, this creates a race condition that will cause the final value of the two pixels to be indeterminate. That is to say, run the same code multiple times, and you might not get the exact same image out of it. There are certainly tools that would make it easy to distribute the same calculation over all the pixels of the image to multiple processors. But those tools will not magically provide the locking you would need to prevent one of the neighboring pixels from being modified while the value of one pixel is being calculated. And the locking code can be tricky, which is why it can't be completely automated. For instance, it would be easy to lock all the neighbor pixels while calculating the value of one pixel. But that would cause the calculation the neighboring pixels to be delayed, thus losing some of the benefit of parallelization. In practice, that example would probably be handled by using a temporary array to hold the output image so that the input image is never modified until the calculation is completely finished, then copying it back into place. But if your code doesn't already do that, it would have to be modified to do it that way. Another trivial example to illustrate the point. There are, in fact, tools that can analyze code and point out constructs that might prevent parallelization, or suggest places that could benefit from parallelization, but use of those tools is not 100% automatic and the ones that are used here are (I believe) proprietary and not cheap. I don't know if there are similar open source tools, but in any case, these tools provide suggestions, but they don't change the code for you. It is unlikely that any significant calculation could be parallelized with zero work. For our users, the investment of time in parallelizing code usually pays off, because this will help their big simulations run much faster, thus saving them time in the long run. We actually have a User Services section which employs people who specialize in helping users write and modify code to maximize performance on our massively parallel supercomputing system. --Greg Rendering (AFAIK) doesn't really require the tight interconnection and coordination of processes that generally characterizes HPC. You can parallelize trivially by treating each frame as a single job--the work per frame is small compared to the whole job, and each frame is independent of the others, so you'll get near perfect speedup that way. We usually call this type of load (lots of relatively small, independent tasks) high-throughput computing (HTC). One HTC tool is HTCondor (Fedora 20 RPM currently condor-8.1.1-0.3.fc20.x86_64.rpm, more info at http://research.cs.wisc.edu/htcondor/). HTCondor manages the submission of large numbers of independent tasks to distributed computers and the collection of results.

Now it seems to depend (and vary from one machine to the other). How do these get decided nowadays? Is there a generic way to get to the correct interface to use in programming?

After all they do not have something similar to SSID to serve as identifier. Open the Network Settings app, select the Wired connection, and click Add Profile. The Identity setting allows you to give the profile a custom name and select a Firewall Zone (among other settings). The IPv4 and IPv6 settings let you select DHCP or Manual, select a DNS server and set routes.

GNOME Shell and password prompts
What app is it now that prompts for passwords when Evolution decides it needs one reentered?

I couldn't find the man page for setfacl but I'll dig around the net and see if I can find it. Just spotted this, so apologies if I've missed some other context, but to pick up on something you said here: It's very unsual to have two owners for a file or directory. It might be possible on some filesystems, but not normal Linux FS. I think you might be misinterpreting the ls -l output of something like (on this RHEL machine), $ls /var/lib/mlocate/ -lhd drwxr-x---. 2 root slocate 4.0K Jun 20 03:26 /var/lib/mlocate/ Where the second name indicates group, not a second owner. Group members are subject to the group permisions, here slocate doesn't have write access to this directory. As a normal user not in the group I don't have read or write access. In the meantime, I'm assuming simply taking ownership of the directory shouldn't open any security holes, right? Well, weakening permissions always has some security implications, but as Harald said it's actually having the web server with write permission that is the thing to avoid. A separate group able to write to the www directory is the right way to do this, if only one user needs it then ownership instead is equivalent. A nice solution to this problem is described in the Red Hat documentation for user private groups, which is how Fedora manages user groups anyway. We have the Web server as a member of a group of users that owns the html directory, along with other users who need to maintain it. Properly implemented, this seems to work well.

I have a Fedora 18 machine on which I use gnome-shell as a desktop. After the last set of updates, I tried to restart. The machine froze during shutdown and I had to reset it from the front panel. Since then, I can't get gnome-shell to start. The greeter runs, but when I log in, I just get the background screen. My keyboard remaps take hold (I swap ctrl and caps-lock to get a Sun keyboard feel), but I don't see any panels. When I tried to troubleshoot that problem, I discovered that /var/log/messages* and some other files were empty. It turns out that syslogd was dead. I've found that it simply doesn't start on boot, but it starts fine when I start it by hand. dmesg and boot.log appear normal AFAICT, though there is nothing in them related to syslog. I've tried googling for solutions, but I haven't find a good set of search terms to target. Can anyone suggest how to start troubleshooting either of these problems?

One further piece of information--logging in as another user works fine, so it's something that happened to my account.

I ran 'systemctl reenable rsyslog' and it appears to work fine now. But I don't know what might have caused the failure.

GRUB2 works more like LILO than like old GRUB, in that there is a configuration file to edit and an installation procedure to get the boot process to use the updated configuration. The file to edit is /etc/default/grub. The installation command is grub2-mkconfig -o /boot/grub2/grub.cfg That command runs some scripts that create /boot/grub2/grub.cfg, which--as you've discovered--you should never edit. /etc/default/grub is a set of shell variable definitions. The one you want to edit is GRUB_CMDLINE_LINUX, which contains a template for the kernel command line arguments. Once this is fixed, the kernel update process should work correctly. If have trouble figuring out what to fix, post the contents of your /etc/default/grub here. If you are annoyed by the missing font file error message when grub2 starts, add the line LANG=C to the top of that file. sean You miss the point. /etc/default/grub was never changed, and CMDLINE is the same as always: GRUB_CMDLINE_LINUX=rd.md=0 rd.lvm=0 rd.dm=0 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rd.luks=0 LANG=en_US.UTF-8 Sorry, the point wasn't clear, as you only referenced editing grub.cfg. Nonetheless, grub2 is putting all the upgrade stuff in the command line. That's the error. The scripts that are run by grub2-mkconfig reside in /etc/grub.d. Is there anything in that directory related to running the update? Fedup apparently involves some systemd services. Are some enabled that should be turned off? sean -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Re: Installing texlive under Fedora 17.

I'm a bit late to this party, but Jindrich Novy's Fedora TeXLive repo for F17 works well. This has been integrated into F18 as the default LaTeX subsystem. The older TeXLive packaging system (the default in F17) didn't work very well at all, which I guess has been your experience. Contra the purists here, my advice would be to wipe all traces of TeXLive--either RPMs or native install--and install this one. http://fedoraproject.org/wiki/Features/TeXLive#TeX_Live_2012_2 -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Last time I had a machine running CentOS (6.2 iirc) I had managed to get a big yellow arrow to show the mouse cursor. It was wonderful. Now I have machines running Fedora (17 18) and Puppy (5.0) -- and even with eyes on two panels I have an awful time spotting the mouse cursor. Can anyone tell me a way to get my arrow back?? Not sure how to change arrows, but if you're using gnome-shell, you can install gnome-tweak-tool and under the mouse settings, you can set the cursor to highlight with a ripple effect when you press the control key. It's nice when the mouse is in a corner or the cursor is a vertical bar, and maybe helpful in your case as well. -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

It is kind of scary interrupting an update, but after about half an hour of no progress, I decided that there was no other way. Do this in a superuser shell instead. It works and gives better feedback: yum update See https://bugzilla.redhat.com/show_bug.cgi?id=922697 PS. I consider software: check for updates less convenient than the pre-F18 sofware updates. I commented on this previously. The Software program in Gnome does not do an yum update for me. It behaves just as you report in F18. Does it work for anyone? It usually works for me, but seems to hang sometimes. I think it's when there is the pop-up dialog for additional packages or deleted packages. When it happens, the progress bar disappears and the updater appears to hang. Killing it and running yum by hand has always worked in that case. -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

It was recommended to mv the files (and/or folders) to be deleted into a tmp directory. I'm planning to try that in my future code, we'll see how things go. Try to be more careful, especially when there is an asterisk involved. And I keep in mind about '..', so no deleting '.*' and how yoill you remove all hidden files of a folder? rm -rf .??* This would miss files with only one character after the dot in the name, like .a, but those can be handled explicitly with less trouble than recovering from mistakenly deleting the contents of the parent directory. this is safe since a very long time [root@testserver:/tmp]$ LANG=c; /usr/bin/rm -rf .* /usr/bin/rm: cannot remove directory: '.' /usr/bin/rm: cannot remove directory: '..'
