I had a heating problem lately after I've been using the xorg driver for the Intel APU (Integrated graphics card) so I upgraded to fglrx proprietary driver.
But then I faced another problem, whenver I wake up my laptop after being suspended, it freezes. In rare cases I can move the mouse a little bit but it's just for 2-3 seconds, and it freezes again. I have to hard-reset it then.
My graphics card is Radeon HD 7730m. How can I fix this ?
