Re: Blank screen on resume
I've used suspend-to-ram very reliably on an old i386 system, but as for this thinkpad yesterday was the first time I could get it to suspend at all ( didn'r really bother that much earlier ).
The two times I tried the machine did come back up so entering reboot <enter> cleanly rebooted the machine.
I did the tests from the console ( without X running at all ) and i added
kldunload nvidia to /etc/rc.suspend and kldload nvidia to /etc/rc.resume. The unloading was necessary to get the laptop to suspend at all, with the nvidia-driver loaded i got/get: acpi0: device_suspend failed.
I could boot fbsd with verbose logging turned on and post the results if that would be of any use.
