Binary package hint: xorg
Booting up the latest 10.04 daily live-cd, the VGA output is unusable. It looks like an incorrect frequency, and the screen size is wrong (it's too narrow for the resolution). The wavering/out-of-phase-ness is so bad that it's impossible to read. This happens on both the X console and X11, and goes away when I use the internal laptop LCD instead (LVDS). If I use both screens in a mirror or extend mode, the same problems occur. So, this led me to believe that the problem might be with Kernel Mode Setting (KMS).
I added the options:
"radeon.modeset=0 vga=771"
to the livecd and, voila, no more corruption. Everything works again, and I can use my big LCD via VGA!
I've attached as much information as I can; I can also show a video of the corruption. I had Ubuntu 8.10 on my computer previously; it's a Dell Inspiron 6400 with Mobility X1400 graphics from ati. I'm using the April 13th Daily LiveCD here, but the corruption was evident at least with the latest Beta livecd.
Let me know if I can give any more information!
