I am using HP ProBook 4520s and have ATI Mobility Radeon whose graphics card doesn't support Ubuntu. Infact, it produces more heat and consumes a lot of battery which causes system usually hangs.
I read somewhere that disabling my discrete graphics card can solve problem. I am not a gamer but a web application developer, hence I think those HD graphics are not neccessary for me. Integrated graphics will be enough for me.
I tried disabling it from BIOS but didn't see any option there to disable it. So can someone please help me to disable discrete graphics card either from BIOS or Ubuntu? It will help my system running smoothly!
Thanks..
I tried the driver from hp site but that didn't work, actually hp recommends and provide driver for opensuse. – Hafiz – 2012-09-03T12:50:32.227
HP wont go and provide drivers for every linux distro out there... Try the radeondriver from here:https://help.ubuntu.com/community/RadeonDriver or the fglrx drivers provided in answer

wel...you should not award the bounty if your problem is not solved... have you tried the 2 drivers mentioned above? – tumchaaditya – 2012-09-10T03:31:42.710
I tried but didn't solved the problem, seems like problem is not of driver but GPU seems to need to power in to work properly (I found this from one of above links) and if this is so then I don't think if there will be other solution. If I always plugin my system then there is no problem. – Hafiz – 2012-09-10T06:49:55.707
