OpenGL apps produce black screen on ATI X1300 using binary drivers
 

hello all,

i'm a bit confused as to why whenever i run glxgears, fgl_glxgears or any other opengl app, all i get is a window where the image would normally be, filled entirely with black. glxinfo etc reports that i'm using direct rendering, and all the vendor strings say "ATI". i'm using kernel 2.6.18.1 and xorg 6.9.0 on slackware 11.

any ideas would be greatly appreciated.

I had the exact same problem on FC3 under the 2.6.14.3 kernel. I've got a Nvidia based GFX card though. My problem was that I needed certain permissions set in the /dev folder to get OpenGL to work at all. These /dev nodes were

/dev/nvidia0
/dev/nvidia1
.
.
.
up to /dev/nvidia7

and then a /dev node called

nvidiactl had to be set to

a+rw

before any OpenGL app would work. I don't know what you'll need to change (since you have an ATI based card) - maybe /dev/ati0 and its associated /dev nodes???
