Xorg segmentation fault


HI,

I am using Slackware 13.1 and recently Xorg server
caused segmentation fault under KDE 4.4.3 twice. Here are listings from
Xorg.log files

Code:

I hope it maybe usefull for someone. I tried the Bugzilla to find if these problems are known, but honestly I don't understand much what
is the Bugzilla all about. Is it for developers?

segmentation fault == stack overflow (if the programmer isnīt sure what to echo) (sometimes)
K-4-Desktop seems to need huge resources (ram ?)
I also had got the hint that permission denied is uttered by seg fault.
What does tty /dev/tty1 at runlevel 2 3 (promt/nox-terminal) say when login (root,password/sudo/su root) startx ?

How to reproduce this problem? Does it happen randomly?

I used KDE 4.4.3 earlier without such problems. Sometimes dolphin crashed.
But Xorg the first time crashed today about 30 sec after KDE started.
The second restart also caused this error. The third restart of KDE
made X Server deaf for keyboard and mouse - I restarted the system remotely form the other computer (to avoid hard reset).

At this moment I am using fluxbox. I will try KDE again later.


I have P4 processor with 1GB RAM, nvidia fx 5500 card. I suppose it is
enough for KDE 4.4.x. But maybe I am wrong.

I am not sure I understand well your question. I started KDE with xinit
(the system is in runlevel 3). After the crash I saw only a full list of
messages from KDE: about nepomukservices and unregistering the keys.

Seem like KDE complains that client (guess Xorg client) was killed and tries to make a clean up. Next time I copy the screen into a file or will run KDE under twm (there will be a heluva lot messages).
