I've been struggling with this a while. I have an older Acer Aspire 5810T with a AMD ATI Mobility Radeon HD 4330 inside it. I've disabled the switchable option and am now only running the HD4330 card, but I'm having trouble with the driver.
I'm running XUbuntu 12.04.5 and I've installed the legacy catalyst 13.1 driver which I manually downloaded from the AMD/ATIs website.
All good so far, it installs fine, except it says "loki_setup (null)". Don't really know what that means but dont think it matters very much.
All right, so I have the AMD Catalyst center installed and I can start games like Dota 2 which I couldn't before (Although the performance is way worse than when I used to run Windows 7. Really not playable honestly) - but now suddenly a Proprietary Driver shows up in the Additional Drivers app. Note that before installing the Legacy 13.1 thingy there was nothing there. Further it says that it's not enabled, so I try to enable it. That seemingly works, and it asks me to reboot - which I do. Now when I fire up Additional Drivers again, its gone. I can't remember exactly, but the name was something like
FGLRX ATI/AMD ...
Also I can't start the AMD catalyst control centre anymore, and I get the error:
There was a problem initializing Catalyst Control Center Linux edition. It could be caused by the following.
No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for you AMD hardware, or configure using aticonfig.
Now if I try to run aticonfig, it says:
aticonfig: No supported adapters detected
So. Is this something I should be worried about? Should I have enabled the driver in the Additional Drivers app at all, or is the driver already enabled when I install with the legacy .run file?
EDIT: Also, now when I try to start Steam I get:
When I check lshw I get this:
