You need to goto Mandrake Control Center and check for errors. Reboot first. Go here Control Center, like start in windoze, then Configuration/Mandrake Control Center.
When that comes up click 'System' Then 'Logdrake'. Put a x above the calender. That way it will only show todays error. Put fail in the 'matching' box. Put a x for messages, syslog and usr then click search.
Look for errors especially agpgart. If you see something that looks wrong post it here. We'll see if it needs fixing.
I had a error for a long time and didn't know it. It caused some problems that I couldn't figure out till I lucked up on that. Random stuff. Really bad. Crashes 'x'.
You're 99% there.
How the how to do? I'm rewriting it but just curious.
