This question already has an answer here:

I've just installed Ubuntu 12.10 64" ready to play some steam games.

The install went fine I did all the updates etc, however I need to install the proprietary AMD drivers (ATi HD5750) for any decent performance, so I go to the software sources and tick the driver listed.

When I reboot I get my desktop picture and mouse but no Unity whatsoever, I can right click the desktop etc but I have no side launcher or top bar.

I've had to re-install totally twice now to try and fix it but still the same each time.

Any help will as always be much appreciated.

Cheers

This question was marked as an exact duplicate of an existing question.

This is known bug. Kernel supplied with 12.10 install disc won't work with AMD driver.

You can probably run terminal Ctrl-Alt-T

  • Remove and purge AMD driver. After restart you will work with Mesa driver. instructions here

  • Update ubuntu to the latest kernel. (Perhaps you already have latest version as you did updates)

  • Install latest ATI driver downloaded from AMD website.

  • (important - this is where most people fail ) Before reboot do sudo aticonfig --initial -f

I installed the AMD driver in my fresh installation of Ubuntu 12.10 following this guide, so there is no bug. – Lucio Apr 28 '13 at 22:13
