[TriLUG] text damage using Intel video

[David Both]

Is this video on the CPU chip or is it on the motherboard or a video adapter?

I have had some trouble with the Intel on-chip video, and sometimes the 
on-motherboard video as well.

I usually use nVidia graphics adapters for my main workstations. I have not had 
any problems with the nVidia cards. For servers and other systems, the Intel 
motherboard video usually works well enough to get the system installed and then 
the rest is SSH access.
