I have a little problem with the proprietary ATI driver for Ubuntu 12.04 LTS. I tried installing it both using the additional drivers as well as a manual installation both times I ended up in low graphics mode! I managed to get back into the Ubuntu GUI by removing the fglrx packages and resetting the xorg.conf but quite frankly I would really like to know the issue for this problem!
Some informations towards my HW:
Asper Aspire 3820TG
Intel Core i5-480M
AMD Radeon HD 6550M
Thanks a lot in advance and best regards!
