random logout
« on: April 13, 2012, 12:43:56 PM »
Recently my box has started to logout from a session and put me back to the login screen.  This seems to happen if I am running two separate instances.  One has general stuff that I'm following and the other has a streaming internet flow.

I think it's a software problem because the machine seems to perform well otherwise.  However, I'm open to the possibility that it may be hardware related.  The machine is a few years old.

Any help in troubleshooting will be appreciated.

KDE

Only the 2 instances of chromium or firefox (or a mix of chromium and firefox).

Yes, I am running compiz.

Same instance of either browser.

the problem could be created by compiz trying to work for both sessions

supposedly the one sleeping shouldn't give problems but it does, at least last time i tried to do what you are doing

try to run the sessions without compiz, just using kwin or no effect to see if the problem doesn't happen

You can toggle KDE effects by pressing [ALT]-[SHIFT]-[F12].

getting logged out to the logging screen usually means X has crashed and you have your system to have you sent to log in screen when X crashes.

Info on the video card you have, video driver you are using and kernel version will be useful here.

Also a log of your x session will also be useful.

The log of the last session should be at /var/log/Xorg.0.log.old

you must be access the log with root's privileges

O.K.  I'm thinking that the problem is with Chromium.  I am running the same setup using Firefox and so far, no problems.  The machine has been freezing up as well.  Only way to escape is to reboot.  Thank goodness for journaled file systems.

I'll check back in if there is anything new to report.  But, keep your eye peeled for problems with the newest Chromium.

I used to have this same problem.
At first I thought it may have been my video card, but it turned out to be my RAM.

Run Memtest and see if you get any errors (you should see a Memory test option in Grub).

In my case I simply had to change the RAM timings and all was good.

I hope this helps.
