[TriLUG] text damage using Intel video

 From what I could tell, it looks like the problem is in some special area of graphics memory where the font bitmaps are stored.  I could open up a gnome-terminal on the EeePC, and every instance of a particular letter would be distorted.  I could resize the font and the letters would look OK.  Resize it back and the letters are messed up again.

To me, it seemed as if some driver was overwriting some area of memory and the font area happened the be poor victim who lived next door in RAM.

I don't know enough about graphics drivers and the whole X11 stack to know whether this makes sense or not.  But it seems plausible and compatible with my observations.
