I've installed ubuntu 11.10 (64-bit) on my HP Pavilion dm4-3002ea (http://h40059.www4.hp.com/uk/homelap...erience=direct) . All work ok except the laptop fan always been on and hot air comming out of it. I believe this to be due to the graphics card.
This laptop has a Radeon graphics card (HD 7470M). But on Preferences => System Info I see the driver been used to be "Intel® Sandybridge Mobile"
When activating the "ATI/AMD FGLRX driver" using the "Additional drivers", the fan stops working and no more hot air comes out of it but the system falls back to compatibility mode, i.e. gnome 3 is in "Fallback" mode.
I've tried downloading and installing the amd/ati drivers from their web site but it just rendered ubuntu unusable and I had to reinstall.
Any ideas how to make it work without overheatting?
