Hello there ...
I've downloaded a package with bleeding-edge from DRI site, compiled and
managed to get my direct rendering enabled. The problem is that when I run
sample programs such as gears, bounce or gloss they only works in direct
rendering mode for a while only say about a minute or less. After that the
program stops. If I run those programs again only the tranparent window frame
appears. This thing happens even if I restart the X window. The onlu solution
is that I have to reboot the machine. By the way my card is S3 trio 3d/2x
