I have followed instructions for every option listed here (uninstalling in between attempts, of course), but each one results in Unity not loading; no sidebar, no desktop icons, and no window borders. Moreover, it's incredibly buggy, with programs like Firefox often crashing after a few moments of use.
Here's a list of some things I think may be relevant:
lsmod | grep fglrxand
lsmod | grep radeongive no output.
fglrxinforesults in a BadRequest error.
amdcccleruns, but also generates a flood of BadRequest errors in the terminal.
lspci -nnk | grep VGA -A3indicates that the system is using radeon instead of fglrx, and fglrx is not even listed as a usable kernel module.
- My /etc/X11/xorg.conf file is here.
FATAL: Module fglrx not found.but
sudo apt-get install fglrxinforms me that I have the latest version of fglrx installed.
- fglrx ran fine on Ubuntu 12.10 (32-bit), but installing Ubuntu 12.10 (64-bit) clean and then immediately installing fglrx results in the problems I am experiencing.
- I am using a Radeon HD 7770.
Some have told me to simply uninstall fglrx and use Ubuntu that way, but Ubuntu is...quite unusable without it. I get about 5 FPS average (with a 7770!) using the default drivers, and compiz runs at 100% CPU.
