Console suspend/resume without X or nvidia.ko
Suspend/Resume works fairly well on my laptop with X. However I'm wondering when I'm not at X, or not running X at all, or even when nvidia.ko is not even loaded.
Currently at the console, vesafb or not, when it resumes the display stays off, even though everything else works. I know with X, we should not use vbetool and the like to do tricky stuff during suspend/resume. But what about without X and nvidia.ko? Would it be an issue for the laptop/bios/acpi, and nothing to do with the nvidia display card?
Re: Console suspend/resume without X or nvidia.ko
After quite a lot of testing with both vbetool and different s2ram options, and acpi_sleep options, with my laptop (ASUS W7J) I still couldn't find a way to wake up the console/vesafb display (no nvidia driver and no X) after a suspend/resume.
Considering the nvidia driver and X are able to do something to wake the display on resume, is there any chance that it could expose this function somehow? Perhaps something like a /proc or /sys value to the nvidia kernel module to reset/wakeup the display?
Additionally, without nvidia kernel driver loaded or X running, after a suspend and resume, I tried to wake the display up by starting X (I can't see the screen but I could still ssh in over network). However X fails to start, and I a NVRM: RmInitAdapter failed! error in the dmesg. Does that sound right at all?
