[opensuse-factory] NVIDIA/Leap 15.0: Console (VT) not working with external display
Hello all,

I have a laptop with openSUSE Leap 15.0 and an external monitor running nicely
- if I
use X.

But I cannot use the virtual terminals on the external display.

If I switch to a virtual terminal/console (e.g. by pressing STRG-ALT-F1), my
displays nothing and goes into powersave.

On the laptop display I get a virtual terminal (crappy resolution, but that's
really an issue).

Since I couldn't get the external display working with the default nouveau, I
the proprietary drivers. I'm now running these RPMs:

user@box:~> rpm -qa nvidia-*

My Graphics adapter is an "nVidia GM107GLM [Quadro M1200 Mobile]".

If I understand correctly, I need a framebuffer device in order to use a virtual
console. And an FB device seems to exist:

user@box:~> ll /dev/fb0*
crw-rw---- 1 root video 29, 0 25. Mai 08:47 /dev/fb0

box:~ # fbtest && echo YES

I'm unsure though whether the configuration is correct:

box:~ # cat /sys/class/graphics/fb0/mode
box:~ # cat /sys/class/graphics/fb0/modes
box:~ # cat /sys/module/nvidia_drm/parameters/modeset

Writing anything to 'mode' doesn't work:

box:~ # echo U:1280x720p-30 > /sys/class/graphics/fb0/mode
-bash: echo: write error: Invalid argument

In /etc/default/grub I have

GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/system/swap splash=verbose"

I already tried appending 'nomodeset' to GRUB_CMDLINE_LINUX_DEFAULT in

GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/system/swap splash=verbose nomodeset"

which didn't work. Switching to


doesn't seem make to a difference either.

I'd appreciate any hints on how to getting my virtual consoles to work on the
external display.

Somewhat related:

How do I switch back to nouveau? Simply uninstall the NVIDIA RPMs? Or is there
option/configuration to be set?

Thanks and regards -- Till
