[Bug 2070313] Re: gnome-shell has high cpu usage and causes significant lag
The lag is occurring once again with MUTTER_DEBUG_KMS_THREAD_TYPE set to `user`, ``` kevin@kevinbuntu:~$ echo $MUTTER_DEBUG_KMS_THREAD_TYPE user ``` I've attached the output of `journalctl -b0` again. It was resolved by putting the computer into standby then resuming. ** Attachment added: "journal.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2070313/+attachment/5799417/+files/journal.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2070313 Title: gnome-shell has high cpu usage and causes significant lag To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2070313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Please try adding MUTTER_DEBUG_KMS_THREAD_TYPE=user to /etc/environment and reboot. That will disable the new highly optimized cursor movement code that was introduced in 23.10.

[Bug 2070313] Re: gnome-shell has high cpu usage and causes significant lag
It's currently maxing out the first CPU core on my laptop. Putting it to sleep solved the problem. While gnome-shell was maxing out the CPU core, I captured the output of journalctl. Hopefully there's nothing too sensitive in there. :-) I had also disabled the extensions previously: ``` kevin@kevinbuntu:~$ gnome-extensions list --disabled d...@rastersoft.com apps-m...@gnome-shell-extensions.gcampax.github.com auto-move-wind...@gnome-shell-extensions.gcampax.github.com drive-m...@gnome-shell-extensions.gcampax.github.com launch-new-insta...@gnome-shell-extensions.gcampax.github.com light-st...@gnome-shell-extensions.gcampax.github.com native-window-placem...@gnome-shell-extensions.gcampax.github.com places-m...@gnome-shell-extensions.gcampax.github.com screenshot-window-si...@gnome-shell-extensions.gcampax.github.com user-th...@gnome-shell-extensions.gcampax.github.com window-l...@gnome-shell-extensions.gcampax.github.com windowsnaviga...@gnome-shell-extensions.gcampax.github.com workspace-indica...@gnome-shell-extensions.gcampax.github.com kevin@kevinbuntu:~$ gnome-extensions list --enabled tiling-assist...@ubuntu.com ubuntu-appindicat...@ubuntu.com ubuntu-d...@ubuntu.com ``` ** Attachment added: "journal.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2070313/+attachment/5795503/+files/journal.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2070313 Title: gnome-shell has high cpu usage and causes significant lag To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2070313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 2070313] Re: gnome-shell has high cpu usage and causes significant lag
Thanks. It's interesting that sleep-resume fixed it. Next time the problem starts happening, please run: journalctl -b0 > journal.txt and attach the resulting text file here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2070313 Title: gnome-shell has high cpu usage and causes significant lag To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2070313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2070313] Re: gnome-shell has high cpu usage and causes significant lag
Thanks for the reply. I noticed today that at just under 6 hours of uptime, the mouse became quite laggy and gnome-shell was consuming an entire CPU again. I had also removed my extensions (they had already been disabled). I tried locking the computer with Super+L but that did not change anything even after the screens went to standby. However, putting the entire computer to sleep (Power menu -> Sleep) did indeed fix it. Is there another issue on here about this problem that I can track instead of this one? re: 23.10 EOL. I'll be upgrading to 24.04.1 once it is released later this year. I'm excited to see the changes! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2070313 Title: gnome-shell has high cpu usage and causes significant lag To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2070313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2070313] Re: gnome-shell has high cpu usage and causes significant lag
Thanks for the bug report. The only similar issue I'm aware of is that sometimes the cursor can become laggy but that is also fixed by putting the screen to sleep (Super+L) and waking it up again. That issue is so rare that I haven't seen it in months. If that doesn't work around your issue adequately then the next thing to try is to remove all local extensions: cd ~/.local/share/gnome-shell/ rm -rf extensions and then log in again. Please also note that Ubuntu 23.10 reaches end of life next month and we recommend 24.04 instead. https://wiki.ubuntu.com/Releases ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2070313 Title: gnome-shell has high cpu usage and causes significant lag To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2070313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
