hello,

i have a new ibook g4 and 3d-support is working. For example tuxracer is working quite nice. But when i activate a opengl-screensaver in the kde controll-center, the screensaver flickers.
glxinfo says that direct rendering is enabled. I have tried the ati and the radeon driver in the xorg.conf, with no success.

here is my xorg.conf:

since 3d is working, it has to be a problem with opengl under ppc ??? (i think)
maybe someone has a solution for me ???

I have this problem on an IBM Thinkpad T41, but only when I'm using KDE or trying to hack my log in screen.

I was hoping to see some help in this thread, but you might check to see if they work in other window managers for you....


Lot's o' luck

[edit]

this:

Option "EnablePageFlip" "On"

also caused me some GL glitchiness with my radeon 7500 mobility...
Probably not the same with your card though?

now i have upgraded to kde 3.4.2 and xorg to 6.8.2-r2.
Now the flickering is gone, but i miss the matrix opengl-screensaver !!!

I have installed kscreensaver and kdeartwork-kscreensaver (both 3.4.2).
But i don`t find the matrix one .....
