Comment 12 for bug 108327

Too bad about the Proview, but let me see if I understand the remaining issues properly:

a. When booting the LiveCD, it detects your onboard video card and configures xorg.conf to use it instead of the added radeon card. (This sounds sort of like Bug #75316, except the opposite, or like bug 103223)
b. It is picking "vesa" for your onboard intel video card instead of "i810" or "intel" as it should
c. After manually fixing it to use the Radeon with the open source 'radeon' driver, it works correctly, except that there is a garbage screen that appears after the boot screen but before the login screen.

Bug c. may actually be in the splash screen rather than in xorg. Can you verify this by modifying your /boot/grub/menu.lst and removing the 'splash' option? If this makes the problem go away, then that bug is in usplash.
