Virtual Console Broken with Nvidia since Kernel 6.0

[terroreek]

Hi All,

Not sure if anyone else is having this issue since upgrading to any of the 6.0 kernels with nvidia cards.  With the 6.0 kernels when I switch to TTY3.  I just have a frozen black screen, I see that getty starts fine, and so does gnome but I just dont have a usable virtual console.  If I boot into the last 5.19 kernel virtual console works fine. 

I don't have this issue on my laptop with an intel gpu so I am assuming this has to do with the nvidia driver and linux 6.0 kernel.

TTY3 means "Strg-Alt-F3" ?

# uname -r
6.0.7-1-siduction-amd64

nvidia470

No problem here.

Two of my systems are KDE/plasma with Nvidia graphics -- I see no performance issues, including tty consoles.  Here's one:

Ok thats weird, I am am have the same driver here the output from my system.  The only thing I can think of is I am running at 3840x2160 at 120Hz and connected to my display via HDMI.

In your /etc/defaul/grub file, have you specified a GFX_Mode line?

[terroreek]

I tried setting it to, GRUB_GFXMODE=1280x1024, which I got from the grub command line.
I will try the other settings.  I also tried passing nomodeset as a command line option as well.

[dibl]

I see your monitor supports higher resolutions than I have. My /etc/default/grub file has this line:

Code: [Select]

GRUB_GFXMODE=1600x1024x24
Have you used the "vbeinfo" command in grub to verify your monitor's capability?

With the 6.0 kernels when I switch to TTY3.  I just have a frozen black screen...

May be a very stupid question:

Is this limited to TTY3? Or does it apply to TTY2/4/5/6 , too?

Yeah when I tried vbeinfo from the grub command line I got an error saying it can't find the command vbeinfo, I did use videoinfo and thats where I saw the capabilities.

The options presented to me were 800x600x32, 1024x768x32, and 1280x1024x32.

GNU GRUB

Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. ESC at any time exit

That's what I get

It affects all of them, If switch to tty3, I can login, and enter in commands I just cannot see anything.  The screen is frozen, to the last text, before, I am assuming the getty service started.  What I mean is if I CTRL + ALT + F3, blindly put in my username and password and then say issue the command reboot, the system will reboot but I dont see anything on the screen until the system reboots and I am presented with my motherboard splash screen.  System works fine, I just can't upgrade my system without booting back to Kernel 5.19.

Just an FYI this issue appears to be either the nvidia driver not having a frame buffer with a kernel change.  I opened a ticket in the nvidia forum and it looks like there a patch submitted but it hasn't been merged yet. 

https://forums.developer.nvidia.com/t/framebuffer-output-stops-since-linux-kernel-6/244467/4

The patch in question; https://patchwork.freedesktop.org/patch/517921/?series=112679

This apparently happens if you have multiple output devices and it look like my 1070 with vfio-pci driver (used to pass the video card to a vm) is triggering this bug.
