Don`t take me wrong, but have you tried to use a # monitor video card? I think I experienced something similar a few weeks ago after I made my first Linux install:) using a S3 agp card. After reinstalling several times and making sure I was not doing nothing wrong, I decided to try another video card (NVidia 16 mg) and since then everything has been running smoothly...I found that only some versions of the x server support hardware acceleration and not all the video cards support this feature, so this could be your starting point. I hope that helps Joao --- Peter Silva <peter@xxxxxxxxxxxxxxxxxxxx> wrote: > > I hope someone can point me in the direction of some > help.
