no,
there's a bug in the proprietary ATI driver, that affects older cards
the bug dumps stupid refresh rates down the card to the monitor, and results in "out of range" messages on your monitor
I *think* you can fix it just by reconfiguring xorg
Code:
sudo dpkg-reconfigure xserver-xorg
unfortunately, being in the AMD proprietary driver, no-one but AMD can fix it, and they don't seem to bothered by it...
as for losing all your stuff,
plonk your /home on a separate partition
doing this, you can reinstall Ubuntu (or any distro) and not lose anything
all your files, settings, email, etc. are stored in /home/username
so if it's on a separate partition, you can wipe and reinstall your OS, and your stuff is untouched
