Hello! I have installed openSUSE-Tumbleweed kde plasma Wayland, I checked hdr on and apply, movies look great, I use an nvidia RTX 2060. The problem is that after reboot I login and then the screen is black, ctrl+alt+F1-12 does not work.
Can this situation be resolved or do I have to reinstall and then make a certain setting so that I don’t have this problem when I restart with HDR?
Thanks in advance for your replies.
Log out (or reboot if you prefer). Then, at login screen, choose “X11 + KDE Plasma” instead of Wayland.
Any difference??
EDIT: might read thru this:
Yes “X11 + KDE Plasma” works, but I want to use Wayland. Hdr works only with Wayland.
Can you please choose kde plasma Wayland, select hdr, apply and reboot, to see if the problem is only at my end?
Thank you!
Sorry … no need for us to test it - we gave up using Wayland long ago because of numerous issues … not worth it for our four machines - very problematic for us.
It seems very few folks have positive results with it.
Good luck!
Please provide input/output from the following:
rpm -qa | egrep -i 'nvidia|veau|open-driver' | sort
inxi -GSaz
If necessary, and it works, use an X11 session instead of Wayland to run inxi. rpm can be run from a vtty. If X11 doesn’t work either, try an IceWM session.

Is behavior the same when you boot previous kernel?
Yes, I used an older kernel. I hoped the new kernel update would solve the problem, but no, the same black screen.
It looks like I’ll have to reinstall it and open hdr only when I watch a movie. I’m almost sure at some point I’ll forget to turn off the hdr and I have to reinstall Tumbleweed once again 
. I hope that future updates will solve this problem so we can enjoy hdr on linux, movies and games.
I am grateful to everyone who made an effort to assist me. Have a good day, everyone!

Possibly you need to change some settings in TV menu.
Turn on TV before OS boot.
IMHO libvdpau_nouveau is not needed.
So it seems the problem with the black screen after reboot with HDR on kde plasma wayland is 100% a Nvidia GPU driver issue.
Now, yesterday I reinstall Tumbleweed (clean install) and the hdr option is no longer present. 
Is there anything I can do, or is this the end of the line?
You can manually enable hdr using: kscreen-doctor.
You need to run:
kscreen-doctor output.[OUTPUT_NAME].hdr.enable
Run the command below to get the output name:
kscreen-doctor --outputs
Now hdr works even if you don’t see it in the display settings. only that the last drive 550.120 makes very saturated colors, the people from nvidia know about the problem and are working on a solution. Let’s hope it resolves quickly.
