OpenGL screen saver problems


I have Mandrake 9.1, and a NVidia GeForce4 ti4200 based video card. After installing linux, I noticed that the screen savers that came with it that use OpenGL (the ones with (GL) next to their title) were running very slow. This was with the default drivers that came with linux. It was obvious that they didn't support acceleration.

So I downloaded the latest linux drivers from NVidia's site, and installed them. The screen savers worked perfectly after that.

Then, the other day, I noticed that all the (GL) screen savers stopped working completely. When they are used, they merely display a black screen. In the KDE Control Center, I can't access the "Setup" for any of them, and the preview is all black.

It seems to me that its a problem with OpenGL in general. I haven't tried any GL-based programs yet, to see if they are affected, because I'm not sure which one's are GL-based.

Any suggestions? It did work at one point...

execute from a command prompt 'glxgears'.
the program glxgears is a little proggie that just puts three gears on the screen and makes them spin... all the while printing out its framerate every 5 seconds... let it run for a while... maybe 30 sec and see what kind of output you get. If you're still getting accelleration you should probably get about 1200 fps... otherwise it might report more like 3 or 400.

another way to determine is to execute 'glxinfo'... this will tell you if acceleration has been turned on or not.

P.S. if the output goes by too fast execute 'glxinfo | less'... this will page the results for you.

You posted this same question 30 minutes prior. Why did you do that? This is double posting and is against the rules.

I'm very sorry, I don't know how that happened. I honestly did not do that on purpose!
