After that, I tried turning off the desktop effects, but that was even
worse in its own way because while the menu scrambling wasn't as
prominent, when I went to shut things down the background went away and
something from out of an old cache was displayed.
Something similar is happening here, when the shutdown menu shows, the
background is "scrambled" (colored noise), but it's a completely different
card (an acer aspire 722 with a radeon hd6250) with a completely different
driver (catalyst driver downloaded from amd, the one from the repositories
didn't work).
I didn't touch desktop effects at all, so I cannot say if they are enabled or
not.
Maybe the root cause of the problem is similar.
nonfree radeon-firmware package is installed, and either the initrds have been
regenerated since (via "bootloader-config --action rebuild-initrds" as root)
or you've done a kernel update since?
No kernel updates, I just let harddrake install the propietary module
and it didn't work (it didn't recognize the card and fell back to vesa).
I then downloaded the catalyst driver from amd and used its installer
(which probably messed up the system but it seems to work, though it
doesn't come back after a suspend).
According to this page
http://bernaerts.dyndns.org/linux/202-ubuntu-acer-ao722
the free driver should also work (and should have no problem with
suspend/resume), but it needs mesa 7.11 while mageia has 7.10.
