auto-cpufreq locks up on Fedora/Gnome

[fonnesbeck]

I'm getting frequent lockups when running on Fedora 40 and Gnome 46. Seems to happen occasionally after wake from sleep (or at least that is when I notice it).

Have you tried?

• Searching through existing/closed issues to see if your bug has already been already submitted? Yes, did not find anything relevant
• If installation failed with auto-cpufreq-installer,have you tried installing auto-cpufreq using Snap package? I am on Fedora, so I don't use snaps
• Have you tried configuring auto-cpufreq? No, not familar with this and not sure what I would configure
• Have you tried suggestions in troubleshooting section? Did not see anything relevant to this issue

@shadeyg56 now that it's brought up I also experience this on Ubuntu. Can you reproduce?

@fonnesbeck silverlining is that only GUI component freezes, daemon continues running in background. You can verify by running auto-cpufreq -stats in Terminal next time this happens.

In meantime since template issue was ignored and wasn't filled out, making this issue invalid for project developers or I to act on.

Hence, please properly filled out requested fields.

Reference:

Fill out informtion requested in this template, without doing so issue will be ignored & closed!

Apologies, added template fields to report.

I'm unable to reproduce this on NixOS. I installed and tested on GNOME as well, on both X11 and Wayland. The GNOME version on Nix is currently 45.5 so maybe its a GNOME 46 issue? Does this issue occur on any other desktop environments?

No, I had this problem with previous GNOME version (wayland)s, since the release of v2.0 that introduced GUI component, I just never bothered reporting it.

Until we had logging for auto-cpufreq-gtk, which I just ran in terminal to see if it'll return anything once it freezes, only thing we can do is what I suggested in 677 to try catching what happens excatly.

Only output I got from auto-cpufreq-gtk after running it in terminal after suspend is: Killed. Please note, this will only happen if you leave it running after extended period of time.

Hi Guys,
I also experience GUI freeze on Cinnamon 6.0.4 (default in Ubuntu 24.04.1 LTS), which usually starts every time after a few minutes of GUI restart.
E.g. "Governor override" horizontal buttons stop working and cores usage is frozen.
After restart GUI usually works for about a minute or so.

grep auto-cpufreq-gtk /var/log/syslog
gives nothing.

Let me suggest to add an option to GUI to generate verbose log, so that we could share it here to help developers.
GUI shows autocpufreq v2.4.0, python 3.12.13.
