I installed deepin 20.6 recently and my laptop has RTX 3060 graphics card. However, I am unable to resolve the issues with a secondary monitor display. At first I was only seeing display on laptop screen but after creating xconfig using a command that Nvidia provided I can see the display on the extended monitor but now the main laptop screen is black.
Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
Please delete /etc/X11/xorg.conf, then follow this:

I followed the procedure. It duplicates the laptop screen to the extended monitor and I am unable to change the resolution of the extended monitor. Moreover, half the extended monitor shows black screen.
Please create a new nvidia-bug-report.log in the current state.

Don’t exactly know why this is happening, might be that your kernel/firmware/mesa is too old for the 11th gen intel gpu. Is is possible to upgrade that?
Also, please post the output of
sudo cat /sys/module/nvidia_drm/parameters/modeset
I don’t think the update is possible, everything is on its latest version.

That’s bad. You could try using the liquorix kernel for deepin and then update the firmware manually.
So I was able to fix the issues without the need to do all those steps. Deepin driver manager software resolved the issue.
