I would be a little careful. Take a look at this site, it is a
collection of information about the fglrx driver for Linux:


That is a link to the main page for Ubuntu, so choose the link there
for your version (although there are _tons_ of other information at that
site as well). From what I remember, I think the recommended procedure
is to get out of X, remove and purge the fglrx driver and related
components, install radeon, and reboot. I *think* - it's been a while
since I did this.

A backup first sounds like a very good idea, and make sure you can
restore from it if things turn ugly :)

But before you do anything, take a good, long look at the above site,
it is the best resource I have found related to AMD graphics on Linux.
There might even be a solution for your original problem there, I'm
sorry I didn't think of this before, but I just remembered it.

"Descendants" of Debian are generally quite good at upgrades, I have
found, but there are always corner cases that might not have been
caught during testing. Messing with drivers can cause problems, so it's
good to hear that you make backups. Many people don't, and then get in
a terrible state when things go bad. :)

You are most welcome, and feel free to ask if there is anything you
need to know :)
