gnome-session logs out with Fatal IO error 11

[Thomas Mayer]

My desktop just froze and I could not press any keys.

When I tried CTRL+ALT+F1 I got logged out from my gnome session and the graphical (!) login window appeared.

There's some messages in my syslog, e.g. gdk-warning gnome-session fatal io error 11 (resource temporarily unavailable) on x server

Plus, the syslog indicates that dbus service has gone ("Unable to contact D-Bus").

Thomas Mayer, to clarify, after the log out, are there any crash files in /var/crash?

[Thomas Mayer (thomas303)]

@penalvch no, /var/crash is empty:

/var/crash$ ls -la

Thomas Mayer, to see if this is already resolved, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[Thomas Mayer (thomas303)]

Generally, the frozen desktop was very very rare/seldom. I'd have to work weeks with the cdimage to reproduce this issue.

In the meantime I don't experience frozen desktops in Ubuntu 14.04.4 any more. Maybe it's already fixed even in 14.04.4. Maybe I see it again in a month or so.

For the moment, I don't have any fatal errors in my syslog:

cat /var/log/syslog|grep -i fatal
<empty>

cat /var/log/syslog.1|grep -i fatal
<empty>

Maybe I can reproduce this issue again in the near future. If I remember correctly, it happened from time to time when working with a Java aplication (PhpStorm/OpenJDK) which produces a significant load from time to time (4 threads at 100%). I'll do similar stuff in the next weeks, maybe I hit the problem again.

Did you have a look at https://bugs.freedesktop.org/show_bug.cgi?id=92505 ?

Maybe you can see if the patch made it into ubuntu in the meantime?

They also state that "Original issue was fixed by updating to video-intel git master". Maybe the corresponding patches made it into ubuntu in the meantime.
