In this case after resume I don't get any display at all. Screens continues totally black. Without the patch, the screen resumes for a moment and then switches to black. Just tried with acpicof -s 3, will try with hw.acpi.reset_video (just to try). I've checked /var/log/messages, and I don't see anything strange. I can see acpi: suspend at 20090324 21:30:41 and then some logs about the resume process. Nothing related to vga, all about wlan, usb, firewire and such, Is there anything I can test ? Greets,
