Hi all,

Initially, my slackware used to crash, the monitor will go into standby and no other responses from anything, keyboard/ctrl+alt+del whenever I was in X for too long or left it on for > 15mins, usually when the screensaver comes on. I have since reinstalled and no more probs have appeared. However, recently, it has started again, although crashing coz of another reason. Whenever i'm testing out some of my programs, it usually crashes during execution (even if I don't get segmentation faults). I've never had this happened before even when I did allow memory leaks (I'm assuming that's wat's causing it), it just seems to crash after 20 or so executions of the program i'm writing. I'm doing OpenGL programming using the GLX library. Any ideas why its happening? And how to solve it? Thanks in advance!!

You haven't gotten an answer yet, and I am not sure that I can solve your problem either. But, you might be able to run linux inside linux using user-mode linux, and that could protect your system from these crashes. Take a look at:

http://user-mode-linux.sourceforge.net/

I have noticed since I went to the most recent nvidia drivers that X was quitting whenever certain screensavers came on. If you are using nvidia drivers maybe try an older version.

This kind of Crash can also happen if:
you compile and install video card drivers to enable 3D acceleration and
then re-compile a new kernel without re-installing the video driver again.
Anytime you install a new kernel source and/or kernel modules, you need to
re-compile the video driver. I have forgotten to do this once or twice
and when a 3D screensaver activates X crashes because the video driver was not re-installed.............

I think that's wat cause my system to crash, recompiling the kernel without recompiling the nvidia drivers. But now everything is "out-of-the-box" stuff except the driver, so I might try downgrading my drivers.

Running linux inside linux huh? Never heard of that before, sounds interesting though, might give it a shot. Thanks for your replies!
