OpenGL apps hangs system

[AtZeuS]

Hi everyone!

I going out of my mind over this one: Every time I start an OpenGL program it runs fine for about 5 second and then there are hangs whichs duration increases over time. After I kill the OpenGL app the whole xserver has become really slow, i.e. it's updating the screen one line at a time. I'm using nvidia-glx on 2.6.15-26-amd64-k8. Here's my xorg.conf but I don't think that's the problem (it's pretty standard). I commented the wacom lines to see if that was the problem.

# /etc/X11/xorg.conf (xorg X Window System server configuration file)

Any help is really apreciated!

Re: OpenGL apps hangs system

you might need to add this line to each device section:
Option "AllowGLXWithComposite" "true"
or disable compositing and see if that fixes the problem

Re: OpenGL apps hangs system

Thanks but that doesn't make any kind of difference. I tried that and I tried running Opengl apps with a clean xorg.conf generated by nvidia-xconfig but the system still hangs on opengl apps. Apparently the problem is not my xorg.conf. Any more ideas?

Re: OpenGL apps hangs system

via the control centre click display
then click at the bottom administer mode

then click for the monitor & graphics change
view the options available and then set them to your required hardware ...

Re: OpenGL apps hangs system

That also doesn't make a difference

However I did see that it reports only 256 KB of video memory! And I have a Asus GeForce 6800GT 256MB DDR3... Maybe that's the problem. Anyone know how to fix this or another way to solve the problem? Thnx

Re: OpenGL apps hangs system

you can specify video ram in your device section(s) by adding this:

Section "Device"
Identifier "Geforce I"
Driver "nvidia"
BusID "PCI:1:0:0"
Screen 0
Option "RenderAccel" "true"
[b]VideoRam 262144[/b]

This option (the mem is specified in kb) is usually not needed, and I do not know how dual cards/ dual head cards affect this at all.

Re: OpenGL apps hangs system

Thanks, but apparently that wasn't the problem either. I noticed games in windows also have hiccups/crashes so maybe it isn't linux related at all

However I still can't figure out what's wrong, I haven't always had this problem, it worked fine a while ago (also on linux). I've flashed my bios and reset the bios settings! What more can I do! Any help is really appreated as this is getting really fustrating

EDIT: I've found out that Xorg eats up 100% of the cpu on the hang/hiccups.... Please help
