Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

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 fglrx and lsmod | grep radeon give no output.
  • fglrxinfo results in a BadRequest error. amdcccle runs, but also generates a flood of BadRequest errors in the terminal.
  • lspci -nnk | grep VGA -A3 indicates 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.
  • modprobe fglrx returns FATAL: Module fglrx not found. but sudo apt-get install fglrx informs 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.

Solved! Log in, and when Unity refuses to load, follow these steps:

  1. Press Ctrl+Alt+T to open up the terminal.
  2. Run sudo apt-get update, type your password, then hit enter.
  3. Run sudo apt-get upgrade
  4. Install any packages that report that they weren't installed. You can do this by running sudo apt-get install PACKAGENAME
  5. Repeat steps 2 and 3 until no packages are installed by step 3 and no packages report that they weren't installed.
  6. Run sudo reboot

And you're done! fglrx should work as intended.
