hello slitaz-lovers,

trying to run google earth it crashes with following code:
Xlib: extension "GLX" missing on display ":0.0". Google Earth has caught signal 11.
xorg and xorg-xf86-video-ati are installed (grafics card ati X1300).

what does "extension GLX" mean? is it a problem of xorg-xf86-video-ati driver or do I have to adjust something in xorg.conf?
