OpenGL apps produce black screen on ATI X1300 using binary drivers
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 220.127.116.11 and xorg 6.9.0 on slackware 11.
any ideas would be greatly appreciated.
