I appear to have the same issue here with a freshly installed 12.10 on a
brand-new HP g6-2245sg. When resuming after suspend, the display stays
dark, while the rest of the box seems to do the resume properly. The fan
starts, the status LEDs go on etc, I can even log on per ssh. So
everything seems to work except of the display.

> WORKAROUND: Change the system time from RTC to UTC.

This doesn't work for me, or I didn't understand what I should have done
here. I changed the system clock in the BIOS so that it should reflect
UTC. I'm in CET so UTC is my time - 1 hour. Is there anything else I
should have done?
