Running 10.04 with an ATI HD3400 (fglrx / proprietary drivers) on a Toshiba Satelite m300 laptop. My primary issue is that laptop suspend does not work... sometimes.
On initial boot, suspend works. I can resume from suspend after that. With initial boot, suspend will work on battery, on AC, or while going to suspend and disconnecting AC.
After resuming from suspend, I can usually suspend again, but rarely can I suspend a 3rd or 4th time.
When a suspend fails, what occurs is that the screen turns black but it is still backlit. I cannot switch to any VT and the laptop is hardlocked.
What I would like to know is how to further diagnose suspend problems or maybe someone has a solution?
Thanks for your help!
