If you are using a NVIDIA GPU built-in laptop please try the following
method.
Execute `prime-select query`.
If the output is not `nvidia`, execute `prime-select nvidia` and restart it.
Please execute `lshw -C display`.
■ *-display UNCLAIMED If is a device of `vendor: Intel Corporation`
If `nomodeset` or `i915.modeset=0` is included in GRUB_CMDLINE_LINUX_DEFAULT or
GRUB_CMDLINE_LINUX in `/etc/default/grub`, delete it, run update-grub and
restart it.
■ *-display UNCLAIMED If is a device of `vendor: NVIDIA Corporation`
If `nomodeset` or `nvidia-drm.modeset=0` is included in
GRUB_CMDLINE_LINUX_DEFAULT or GRUB_CMDLINE_LINUX in `/etc/default/grub`, delete
it, run update-grub and restart it.
If `inxi` is not installed, please run `apt-get install -y inxi`.
Please execute `inxi -G`.
If `drivers: nvidia` is displayed, you need to add the following to
`/etc/X11/xorg.conf`.
```
Section "Device"
Identifier "intel"
Driver "modesetting"
Option "AccelMethod" "None"
EndSection
```
If `drivers: modesetting,nvidia` is displayed, please delete or comment out
`Monitor "Monitor 0"` from `Section "Screen"` including `Device "nvidia"`.
```
Section "Screen"
Identifier "intel"
Device "intel"
Monitor "Monitor 0"
EndSection
Section "Screen"
Identifier "nvidia"
Device "nvidia"
# Monitor "Monitor 0"
DefaultDepth 24
Option "AllowEmptyInitialConfiguration" "on"
Option "IgnoreDisplayDevices" "CRT"
Option "ConstrainCursor" "off"
SubSection "Display"
Depth 24
Modes "nvidia-auto-select"
EndSubSection
EndSection
```
Then restart it or execute `service gdm3 restart`.
that's all.
This problem is caused by the fact that nvidia-xconfig generated
/etc/X11/xorg.conf does not include the loading of the modesetting driver, and
the monitor output is connected to the nvidia device.
(I am not familiar with X11 so I do not know if that is correct)
Perhaps the smallest /etc/X11/xorg.conf that solves this problem is:
(BusID varies depending on the environment)
