Public bug reported:
If I connect a secondary monitor to my HP 2730p via VGA, the screen
resolution gets detected correctly as being 1920x1080. However, the
actual output sent to the monitor is 1650x1050. So a 1920x1080 picture
is somehow sent with 1650x1050, rendering it completely unreadable. It
looks like an extreme tearing effect.
This occurs after booting when the console output switches to the actual
screen resolution, but before X starts. Running X, the screen can be set
up to 1650x1050, but the tty console output is still scattered,
regardless of the X resolution. fbset also does not change the
resolution.
I could reproduce this behaviour with a Maverick live CD, but on Karmic
everything is fine, still.
