OK, I'm on my third install of Ubuntu 12.10 in three days AMD A6-4400M APU with Radeon HD Graphics laptop and I cannot get the graphics working.

The default driver has terrible tearing and when I pull up 3-D games the tearing is worse (but at least they come up). When I try the proprietary drivers from Ubuntu the tearing is still there but now 3-D stuff does not work (I don't remember the error message now but I think it was something about GLX).

When I tried the drivers from ATI then X would not start or when I finally managed to get it to start (don't remember how) all the same problems were there and 3-D did not work. Installing the beta driver from ATI caused the entire system to break -- could not login or switch consoles, anything, had to reinstall from scratch.

So, before doing all the same things again hoping something will work this time does anyone have some advice that will make it all work properly? Should I be using Ubuntu 12.04 instead? Any other Debian-based distro perhaps?

And did you removed the drivers before installing other drivers?. Also which Radeon HD GPU do you have?. –  Uri Herrera Jan 10 '13 at 19:50
    
It has the AMD Radeon™ HD 7420G GPU. As far as I can tell I removed the previous drivers before trying the others. As of right now I have a clean Ubuntu 12.10 install so I'm looking for how to go from here. –  bfootdav Jan 10 '13 at 20:05
    
You can try directly Installing the non beta Catalyst drivers, without using the ones that come with Ubuntu first. Also, when you get errors or the like add them exactly as they appear to your question it makes it easier to know what's wrong. –  Uri Herrera Jan 10 '13 at 20:06
    
OK, I installed the Catalyst driver directly and rebooted. X came up but when I try to run a 3-D game (neverputt in this instance but it's been the same for other games in previous installations) I get the following: X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode failed request: 153 (GLX) Minor opcode failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 13 Current serial number in output stream: 13 Also, thanks for your help. –  bfootdav Jan 10 '13 at 20:44
