One more dump for this issue: (ran for near 10 minutes): pid 4154 is
still CPU eater gnome-shell process
sudo strace -c -p 4154
strace: Process 4154 attached
^Cstrace: Process 4154 detached

The question would be - why recvmsg failed in 130460 times (out of 154109 total
calls)
that looks weird!

Title:
Gnome shell easts 100% of the C
Thanks!
I'm thinking about upgrading to 24.04 LTS
but the last upgrade (20 -> 22) was very painful... (my disk is encrypted and
smth went wrong so it took me 2-3 days to recover...
the funny thing is that I never hit that nasty 100% CPU issue in the older
Ubuntus

20 is a reasonably low numbered file descriptor so it might be the X11
connection (it's a Xorg session).
Makes me wonder how many CPU issues have been fixed since 22.04...

Right now I can only recommend upgrading to Ubuntu 24.04 as soon as is
convenient.

I don have Xwayland process (I guess I switched to X11 as teamviewer
insisted on that)

hmm after executing this -
gnome-extensions disable ubuntu-d...@ubuntu.com
my Ubuntu left panel with icons is GONE! :)
that's very unfortunate :)

Yes! it still running

Is the Xwayland process also taking up a lot of CPU? (some load trackers
will show you the combined usage of a process and its children, Xwayland
is a child of gnome-shell)
If so, that would be bug 2043517

If process 4154 is still running then what kind of descriptors are 6 and
20?

Are you sure it's a gnome-shell process using all the CPU? If so then
next please run:
gnome-extensions list --enabled
and then try:
gnome-extensions disable
for each, to see if any of those are causing the bug.

one more idea -
I tried to look under the hood of the gnome-shell process and I see lot of

is it kind of expected?
eg:
sudo strace -p 4154
strace: Process 4154 attached
poll([{fd=20, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=20,
revents=POLLIN|POLLOUT}])

Thanks!
executing:
1. ls ~/.local/share/gnome-shell/
application_state
contents of the file:
$ cat ~/.local/share/gnome-shell/application_state
2. left for some minutes
1. Check that ~/.local/share/gnome-shell/ still has no 'extensions'
subdirectory.
2. Check to see if the high CPU correlates with any repeating log
messages:
journalctl -f

Hi @vanvugt!
Thanks for fast reply
some stats:
so I've got just 2 ext in the above dir:
$ ls
application_state gnome-overrides-migrated
removed those 2 and lets see if the issue will be reproducible again (it
happens in 5-6 days, not instantly...)
PS
gnome-overrides-migrated
file is of 0 si
Thanks for the bug report. Please start by deleting any local
extensions:
cd ~/.local/share/gnome-shell/
rm -rf extensions
and then log in again. Does the problem still occur after that?
