I have very strange problem. After suspending to ram notebook doesn't wakes up, only leds and fan switches on, no HDD activity and display stays off(without backlights-completly off). If I press numlock- led doesn't switches, all buttons are not warkable. I have installed uswsusp and tryed to use s2ram, but result is exactly similar. I tryed to remove fglrx, but useless. I have HP Pavilion dv6 2055er with Ubuntu 12.04 on board and: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV710 [Mobility Radeon HD 4500/5100 Series] How can I solve this problem?
