GDM Goes Blank - Clutter warnings in the log

freelook · 2014-08-25 02:07:02

I and 3 other users use gnome3 with gdm on my desktop. Switching between them works at first, meaning when I click "Switch User" to go back to gdm, I see the list of users.

Eventually, this stops working though. It's unpredictable but by about the 5th time switching users, all I see is the gray gdm background. Everything usually seems to be clickable in this state. Clicking the upper right corner still brings up the menu, and I can click users if I can remember where they were on the screen, and I can enter in the password blindly, hit enter and get to a desktop. I'm not sure what is causing this. Can anyone please help me fix it?

Here is my video card (I'm running the nvidia driver):
01:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 650 Ti] (rev a1)

My system is up-to-date. I just did a pacman -Syu today.

Here is what the log says right at the point where the first click of "Switch User" fails and brings me to the gray screen:

And interspersed with that are the following 2 lines, that repeat about 800 times:

I'd appreciate any help with this issue. And please let me know if there is any more information needed.

I'm having a similar error but with critical errors not warnings, and my desktop freezes sometimes (gnome 3.12), everytime is happening more often.

i don't know where this error is coming from, I'm not using clutter or anything similar

Is it safe to uninstall it?

Thank you.

I think if you're using Gnome, then you're using clutter. Clutter "draws" the "windows" for Gnome.

Koven · 2014-08-25 15:04:15

Yes I see there's no way to uninstall clutter.

I'm trying this

https://bugzilla.redhat.com/show_bug.cgi?id=1069299

But I've gaot this error

koven@koven ~ % cat /etc/sysctl.d/99-sysctl.conf              
notify.max_user_watches=100000
koven@koven ~ % cat /proc/sys/fs/inotify/max_user_watches
8192

When I run this command Iget another error

koven@koven ~ % sudo sysctl -p /etc/sysctl.d/99-sysctl.conf
sysctl: cannot stat /proc/sys/notify/max_user_watches: No such file or directory

I don't understand why it asks for /proc/sys/notify/max_user_watches if the file is /proc/sys/fs/inotify/max_user_watches.

Please let me know what I'm doing wrong.

thank you!

All of this has nothing to do with my question. I think my thread has been hijacked :-(

I found the answer to my question though so I'll post it here. Apparently there is a bug with GDM that was reported in May:

https://bugzilla.gnome.org/show_bug.cgi?id=730360

No workarounds, just a broken system. :-(

Should I mark this as solved, since I know what the problem is, even though there is nothing I can do?
