Bug description:
i have laptop (Vendor:MSI / Model:Katana GF76 11UC) with two graphics
card (onboard intel+nvidia rtx3050)
I didn't like how intel (i915) works (flickering problem has not yet
been overcome) so I decided to try using nvidia only.
I spent a long time dealing with the "xorg" settings in order to run "x" on
nvidia only:
* disable the i915 driver with kernel settings: `modprobe.blacklist=i915
i915.modeset=0`
* rename /usr/share/X11/xorg.conf.d/20-intel.conf to *.bak
* then modify /usr/share/X11/xorg.conf.d/10-nvidia.conf (set Identifier
"Card0" )
after starting startx on the screen, the image freezes when switching to tty2
and back to tty1, the server does not render anything, and if you open `top` in
tty2, you can see:

```
Thus, I stated that the X's started up and are working, but the image is not
displayed.
if return
modprobe i915.modeset=1
/usr/share/X11/xorg.conf.d/20-intel.conf
/usr/share/X11/xorg.conf.d/10-nvidia.conf
- otherwise the output always goes through only intel (i915)
nvidia not uses even if use `prime-select nvidia` - this option ignoring
