["Ville M. Vainio" <vivainio@xxxxxxxxx>]

I'm commenting to explain my solution for the posteriority:

- It seems that watching a video from tv-out in Windows (dual boot)
screwed up my monitor ( acer al2216w ). I started getting the "bad edid
checksum" errors from X.

- The problem appeared simultaneously on Ubuntu 9.04 and Debian "Lenny"
(yes, I have 3 operating systems on my hard drive).

- I solved it by "rebooting" my monitor - that is I unplugged it for a
while, and reconnected it. This should definitely be tried before any
other tweaks.

- Even without monitor reboot, the windows drivers worked fine; it was
the Ubuntu drivers that required it.
