I have a Dell Vostro 3350 with AMD video card. I've installed ubuntu 12.04 and the latest driver from amd.com (12.3).
Starting with discrete (
) it works fine with default Gnome (I think this is what you are referring as unity 3d), but my laptop gets warm really quick and the fan is really loud. (Though I get a good FPS in fgl_glxgears). When I switch to integrated (
), if I start default Gnome it hangs up after login (no unity 3d), but with Gnome 2D option it starts, but flickers heavily (the cursor, the windows etc, it is really annoying).
I would prefer that AMD would be turn off (only integrated) by default and sometimes when I would need some 3D accel, I would turn it on, but integrated would have the primary usage.
Is anybody experiencing this aswell? I can provide any output I can get from commands you need.
Thanks for any guidance!
When I switch I get this in console:
I am using 64-bit version of Ubuntu 12.04. Maybe this is the one of the problems?
