Screen resolution "failed to get size of gamma for output default"

English Hardware
#1

I just installed Leap 15.5 on my computers. Two of these use the same monitor (alternatively), a BenQ SW2700. On one of the two computers, everything went fine: screen resolution I use is 2560x1440, and refresh rate is 60Hz. But the other computer (that worked all right before I installed 15.5), does not recognize the monitor: it says “default” and gives only a 1680x1050 resolution and a 77Hz refresh rate. For the same monitor!!!
I give the messages of both computers (xrandr and inxi) here. First the BAD one (not recognized):

I am working in KDE Plasma, cannot find kscreen-doctor or such programs. How do I force the “BAD” computer to recognize the monitor that the other recognizes without problem, in the same software configuration?
I am thankful for your help!

I try to correct my use of the Blockquote here …
I just installed Leap 15.5 on my computers. Two of these use the same monitor (alternatively), a BenQ SW2700. On one of the two computers, everything went fine: screen resolution I use is 2560x1440, and refresh rate is 60Hz. But the other computer (that worked all right before I installed 15.5), does not recognize the monitor: it says “default” and gives only a 1680x1050 resolution and a 77Hz refresh rate. For the same monitor!!!
I give the messages of both computers (xrandr and inxi) here. First the BAD ones (not recognized):

I am working in KDE Plasma, cannot find kscreen-doctor or such programs. How do I force the “BAD” computer to recognize the monitor that the other recognizes without problem, in the same software configuration?
I am thankful for your help!

#3

The failing one, with NVidia, shows a driver problem in inxi output. The nouveau kernel module isn’t included in kernel-default. The Turing needs kernel-default-extra to get it, or NVidia’s proprietary drivers.

grep /dev/dri/card /var/log/Xorg.0.log*

Run the above command from Konsole on both computers. I expect you’ll find they differ, though they shouldn’t. Likely the Turing will return something like:

(EE) open /dev/dri/card0: No such file or directory
#4

Well, I have to thank you thoroughly! I installed nVidia’s proprietary drivers through Yast repositories and then “zypper inr”. After rebooting, everything was fine again. It’s good that there is a community to help each other …

#5

Now that the monitor is recognized and the screen works, here are the better results thanks to the nVidia drivers, for xrandr and inxi-SGa:

But again, THANKS so much for your help!

It seems that you try to show us copied/pasted terminal text. Can you please use the </> button around them?

#7

I will use the / symbol here instead of the ” symbol I used in my previous messages.
