Hi people,

I just installed Ubuntu 12.04 on my Dell 15r Inspiron n7520 with hybrid graphic cards system Radeon HD 7700M on board. Everything works great on Intel's graphic, but on Radeon the movement is choppy and laggy (for example dragging windows or youtube videos on any browser). I am using drivers from the website (tried 13.4, now I am using 13.8) http://support.amd.com/us/gpudownloa...eon_linux.aspx but, without satisfied results. The laptop is dedicated for Ubuntu 11.04 (or 11.10?) so the sollution should be somewhere in the space, but I havent found yet.

My question is: If you are using the same laptop or at least the same graphic card, what AMD driver you use from list of previous drivers? http://support.amd.com/us/gpudownloa...eon_linux.aspx

Ofcourse if you have idea for other sollution, I will be thankfull.
Thanks in advance
