Weird "static" after X loads
I'm running Mandrake 9.2 with the NVidia-supplied drivers (NVIDIA-Linux-x86-1.0-4496-pkg2.run) on a Dell Inspiron 5150 (GeforceFX Go5200). As far as I can tell, the drivers are working perfectly except for some weird "static". I only get this static after running glxgears or after a few minutes of normal (non-3d) activity. WinXP is fine. Even if I quit X the console is staticy. The only way to "fix" it is to reboot into XP, then back into Mandrake.
Has anyone seen this before? I hope this is fixable, as I specifically bought an NVidia-powered laptop so I could run Linux.
