I just acquire a Compaq Desktop (CQ2000 / cq2025). It's not a real desktop, as the internal hardware is much more akin to a laptop, but I digress.
At any rate it contains an AMD Radeon 6320 onboard video card.
Immediately following the install of debian whhezy/sid ... I noticed the video went haywire (just lines, but I could guess the mouse was moving as a solid block/cursor).
Since I had installed it as an SSH server, I simply logged in, su-ed to root and did the following :
i) apt-get clean, apt-get autoclean, apt-get update, apt-get upgrade, apt-get install make, apt-get install bison, apt-get install linux-headers-22.214.171.124-amd64.
ii) from my other functional unit, I downloaded the driver listed here : http://support.amd.com/us/gpudownload/l ... ng=English
iii) ftp-ed it over to the compaq.
iv) changed the properties by typing : chmod ugo+x amd-driver-installer-12-4-x86.x86_64.run
v) ran it straight (as-is) CQ2000:# ./amd-driver-installer-12-4-x86.x86_64.run
vi) I chose all the default options
-> it actually seemed to hand since I had ssh-ed with the -X option, but nonentheless, upon reboot I had a functional display.
Some of the apt-gets might be trivial, but it's my tried/true recipe.
Hope it helps anyone out there panicking because they don't have any video ...
Live long and prosper.
