I recently defenestrated this laptop and I'm having some issues with the graphics.
I'm seeing some pretty nasty screen tearing on this thing. I didn't notice any while the machine had windows 8 (a brief amount of time, admittedly) which leads me to suspect some kind of driver issue.
Googling led me to some tearing issues from ATI drivers and the new version of X but since most posts are a bit dated I don't know if that is what is happening to me.
The machine is a g6-2211nr model with an AMD A4-4300 APU and it's running 12.10.
The computer details dialog is showing "Driver: Unknown"
I installed the proprietary drivers. Upon reboot I reached the login screen and it looks flawless. However, after accessing my account, I can only see the desktop background and the mouse pointer. Nothing else.
I successfully reset everything. I'm back in but the screen tearing is back. I checked to see if the tearing appears during the login screen with this "working" configuration that uses the opensource drivers and no, tere is no tearing during the login screen no matter how hard I try to bring it about.
Here is the output of lshw -c video right now:

Aside from a fix, isn't there a way to just turn off hardware acceleration altogether? Just CPU render the whole thing?
