Description Daniel Wolstenholme 2005-10-06 02:28:35 UTC

KDE intermittently and randomly logs me out (or more accurately, it probably 
crashes, bringing me back to the kdm login screen very quickly).  I have 1GB 
of RAM, and another GB of swap space; I don't appear to be running out of 
memory, judging by my on-screen meters (KDE System Monitor applet).  Usually, 
when I run out of memory because of Konqueror's memory leaks, some important 
process gets killed, such as kwin, requiring me to Ctrl-Alt-F1 and login to 
kill the remaining processes and re-login.  This is very different; it's too 
convenient and clean in that everything just vanishes and I'm suddenly 
returned to the kdm login screen as if I had just turned on the computer.

we need logfiles. ~/.xsession-errors /var/log/messages - dmesg output

dmesg output

Ok, let me know if you need any more files.

Comment 5 Stephan Kulow 2005-10-06 07:27:13 UTC

nothing in there indicates any crash. Are these log files after such a crash? 
If so, I guess we need /var/log/Xorg.*.log

Xorg.0.log.old file - shows crash

This one seems to show the crash at the end, while the non-old one doesn't, but
I'll upload them both anyway just in case.

/var/log/warn file

This shows the crash as well.
I've trimmed it down to just today's messages

/var/log/messages file

This shows the crash as well.  Might be helpful.

Comment 11 Daniel Wolstenholme 2005-10-08 03:13:40 UTC

Ok, I've uploaded a bunch of files from my /var/log directory, showing the 
crash.  I've trimmed a couple of them to just today's output so they wouldn't 
be so huge.

Comment 12 Stephan Kulow 2005-10-08 07:23:44 UTC

the interesting one is Xorg.log - the X server is crashing

Comment 13 Stefan Dirsch 2005-10-08 07:29:00 UTC

Please attach the results of "nvidia-bug-report.sh".

nvidia-bug-report.log file

Ok, here it is.  Do you think this is an Nvidia-specific problem?  Should I
send this over to them?

Comment 15 Stefan Dirsch 2005-10-08 08:18:43 UTC

Thanks. Yes, I think so. I've added Andy to Cc. Maybe he has a hint. For now I 
would recommend to uninstall the nvidia driver. 
 
  nvidia-installer --uninstall

Comment 16 Stefan Dirsch 2005-10-08 08:37:09 UTC

Settting to NORMAL. Probably we can't help here (nvidia driver issue). The nv 
driver should work for you reliable.

Comment 17 andy ritger 2005-10-08 19:16:04 UTC

What is the approximate frequency of this, Daniel?  (eg: once a week or so?)

Here are a few experiments to try:
- does this reproduce if you disable Xinerama?
- does this reproduce if you use TwinView rather than multiple X
  screens on one GPU with Xinerama enabled?
- does this reproduce if you disable GLX (don't load the glx module)?

Thanks,
- Andy

Comment 18 Stefan Dirsch 2005-11-10 15:45:02 UTC

Daniel, could you help here?

Comment 19 Daniel Wolstenholme 2005-11-10 15:51:11 UTC

Sorry, I've been pretty busy lately.  However, in the meantime I've also upgraded to SUSE 10.0 (the release one) from RC1 which this bug was reported against, and I haven't had this happen any more.

Comment 20 Stefan Dirsch 2005-11-10 15:56:02 UTC

Ok. Then let's simply close this one as FIXED.
