I've just installed 12.04 LTS on my laptop and I'm having some problems with the screen.

Whenever I change from a window to another, the screen seems like it had stripes; but after two or three seconds, it works in a normal way.

The same thing happens when I'm writing on the keyboard happens, so I can't see if I'm writing right or not.

I've tried to install the additional controllers that appear on the system configuration menu, but when I click on the activate, after a minute or so appears a message saying:

We are sorry, the installation of the driver failed:
Check  the log to see the details:/var/log/jockey.log.

There are two additional controllers:

  1. FGLRX propietary graphics driver for ATI/AMD (post-release updates)
  2. FGLRX propietary graphics driver for ATI/AMD

My computer is a Toshiba Satellite L850-150.

I hope you can help me.

Install the 2nd driver, as I believe the post release updates aren't supported anymore. If that doesn't work, manually install them:

sudo apt-get remove --purge fglrx fglrx-amdcccle

sudo apt-get remove --purge fglrx-updates fglrx-amdcccle-upadtes

Restart. Then:

sudo apt-get update

sudo apt-get install fglrx* fglrx-amdcccle fglrx-dev

sudo aticonfig --initial

Restart, and the drivers should be installed.

Double check:


...And if it outputs something like:

display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 6300M Series
OpenGL version string: 4.2.11733 Compatibility Profile Context

thank you! this solved the problem, but just when I'm using batery, when I remove it, and plug only the charger, it doesn,t work. What should I do? – David Aug 25 '12 at 10:45
Sorry, I have no idea what could be causing that. You can always download the latest drivers from AMDs homepage, though I haven't tried this before, remove the drivers you installed before through the commands in my previous answer, then run sudo sh [driver].run replacing [driver] with the name of the driver. – Marco Scannadinari Aug 26 '12 at 11:15
