The nvidia driver knows a lot more than nv. It can tweak both X and the
kernel to do things, it is much easier for nvidia to support s2ram.
Yes, I understand that. But I prefer to use free software.
With linux's acpi_sleep=s3_bios, I execute s2ram -f. At resume, the
computer works, but the screen is black, pressing CapsLock does not
change the LED.
Here's what the upstream dev thinks about this:
< bgoglin> aaronp: what's the status of s2ram with nv? should work?
buggy and might be fixed? wontfix?
< aaronp> My understanding was that it works as long as the system POSTs
the GPU on resume.
< ajax> which only works if the BIOS is there to be POSTed.
< aaronp> right
You might want to try passing -p (or maybe -s) to s2ram in case it
helps. Try switching to VT console before suspend too.
But there is nothing more to expect from xserver-xorg-video-nv.
Thank you for help, I'll try very soon and keep you informed.
