I'm desperately in need of help with figuring out how get my AMD ATI Radeon HD 7650s graphics to work on my HP ProBook 4540s laptop. I have tried a few distributions ( ubuntu 12.04 LTS, ubuntu 12.10, Mint Maya, Mint Nadia and none of them works.
It says "Uknown" when i check the system information and some programs that needs it activated rejecting to load due to the graphic card not installed properly.
this is what i did.
sudo chmod +x /home/username/Downloads/amd-driver-installer-12.6-legacy-x86.x86_64.run
sudo sh /home/username/Downloads/amd-driver-installer-12.6-legacy-x86.x86_64.run
sudo aticonfig --initial
