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:
- FGLRX propietary graphics driver for ATI/AMD (post-release updates)
- FGLRX propietary graphics driver for ATI/AMD
My computer is a Toshiba Satellite L850-150.
I hope you can help me.
