what can I do to stop this? are there some kind of write permissions set because I'm having trouble with ATi's linux drivers too, I did an alien on the rpm and that went fine, but doing a dpkg --install wasn't so successful, let me try it again and post the error:

Code:
root@risingedge:~# dpkg --install fglrx-4-3-0_8.10.19-2_i386.deb
