I've just installed Ubuntu 13.04 but i wasn't happy with the standard graphic driver Ubuntu came with on my laptop, although the graphic was smooth, the movies played on full screen were "framing" visibly and the laptop had problems recognizing other monitors via docking station. I decided to install proper AMD drivers from: http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx
I just typed
./drivername.run and went through the graphical install process, restarted and got this:
The system is running in low-graphic mode. Your screen, graphic card, and input device settings could not be detected correctly. You will need to configure them yourself
I tried to recover to the original setting but I didn't see Unity anymore. I reinstalled Ubuntu and followed step by step what's described here: How do I get AMD/Intel Hybrid Graphics drivers to work?
Unfortunately, I got exactly the same result: the same error message after the restart. I tried to do something with it so I restored my previous config (as Ubuntu proposed) but again I never saw my Unity anymore. After the login, I can only see the desktop with icons but no bars, no nothing... useless... I cannot even get to the terminal.
I desperately need some help and I have gone through so many forums and threads, but haven't found a reasonable solution. Does anyone have any ideas?
