I am using opensuse 12.1 (64 bit) on my system (i7, 16GB ram Nvidia 240GTS).
My x-server randomly restarts, without giving me an error or backtrace.
This usually happens when I am using matlab to plot 3d figures, or comsol to plot 3d figures and sometimes on chrome while broswing. For some reason I am suspecting nvidia. But I couldn’t find anything on the log files.
So the latest Long Lived nVIDIA driver is up to version 295.59 while I see you are using 295.49 so have you considered doing an upgrade? I will say that normally, the word server is not used when it is being used to directly load and run graphic applications. In any event, a newer video driver might be helpful to try. Other things you can do include a complete cleaning of the PC for any unit that has not been cleaned in a year or so. This mainly is done by blowing all dust out of the PC and its heat sinks and a resetting of every plug, cable, adapter card and such inside the case or just blowing out dust in a Laptop computer. One could try a newer kernel version, clear up to version 3.4.4 for instance. I have bash scripts that can help in the video and kernel upgrade department if you need them.
Yes, defective RAM can do this. Normally though I recommend the PC cleaning described before and the reseating of memory modules before I would suggest they be replaced. If the PC does work long enough to install a newer Video driver it might be worth a try. You must remove the nVIDIA repository and uncheck the nVIDIA driver loaded in YaST before you would proceed. I normally install the driver the hard way following these guides. Make sure all files are in place and downloaded before you would do anything using YaST. Make sure to read through all documentation as well.

There seems to be some confusion here. marios geo mentioned his
‘x-server’. I take this to mean his X server. The X server is an
application that controls graphic displays. It forms the basis of almost
all Linux displays.

There seems to be some more confusion here, or possibly some off-forum
conversation. I have seen no suggestion that the system is locking up at
all, let alone locking up rapidly.
marios geo said that his x-server was crashing when running particular
graphical applications. So this appears to be an application level
problem that does not affect the system’s integrity. (the applications’
problems may still be caused by system-level defects in hardware or
drivers, of course). But as long as marios does not try to
simultaneously run matlab whilst installing an updated driver, I see no
reason to expect difficulty. If there is difficulty, then the obvious
step is to switch the system to runlevel 3 and perform the update using
As well as updating the nvidia driver, it may also be worth trying the
open-source nouveau driver. That would help isolate problems and might
provide a workaround.
