NVIDIA devs: any ETA on FBDEV (console mode setting) implementation?

That’s really really sad because recent NVIDIA drivers have become incompatible with Vesa FB :-( Whenever I try to shutdown or reboot my PC, my console blanks/goes black when the X server exits. That also means I cannot change runlevel from 5 to 1(or 3), because the screen will go totally black.

Here’s my kernel boot options:

vga=0x34c video=vesafb:mtrr:3,ywrap

Pre 37x.xx drivers ran just fine with it, everything new doesn’t. I know NVIDIA has never guaranteed that any text console mode, other than plain 80x25, will work but it worked up until half a year ago.

Hmm, that does sound strange. I saw your post about this in the other thread – I’ll reply there.

However I’m curious: most modern PCs run UEFI and UEFI is driven by UefiFB which must work with NVIDIA drivers, yet VesaFB doesn’t any longer.

The UEFI GOP driver always puts the screen into a mode that nvidia-modeset should be able to restore natively, and uefifb never changes it. So it should always use the new console restore path.

vesafb sets modes that, depending on the configuration, may or may not be compatible with the new console restore code, so the driver will either try to restore it natively or fall back to using the VBIOS to do the modeset. That’s why we don’t officially support non-text mode on legacy boot systems.
