I plugged openSuse into a TV with an HDMI cable, the connection happened but it just shows an empty screen
When I try to switch between virtual desktops it appears quickly but immediately returns to the empty screen
What should I do to see the normal screen?
You’re not able to move the mouse pointer into the space it provided from any direction? Empty meaning what, black? white? green?

Try how?

Provide more information, while the TV is connected and has “appeared”:
sudo inxi -U
inxi -GSayz
xrandr | egrep 'onnect|creen|\*' | grep -v disconn | sort -r
cat /var/log/Xorg.0.log | susepaste
Copy and paste here, using code tags around your paste ( # ] above the input window), the input and output from the last 3 commands above. The first just updates inxi to a less broken newer version, so that transaction’s output is not relevant to solving your problem.
As far as I know, you first have to look at your video driver(s). The Intel video driver does not work (well) for hdmi connection and so it is better to use the nvidia proprietary driver or the amd driver.
Yes, I can move the mouse pointer to the given space from any direction. But only when I swipe past the right side of my PC All In One screen
Empty meaning what, black? white? green?
Sorry, the correct thing is that it is only showing a part of the normal screen. Maybe 15% of the original screen. Taskbar and my icons don’t appear because they are elsewhere. II noticed that when activating one of the desktops, a window appears that does not even appear on my All In One PC monitor Another fact: When I turn on the HDMI on an external monitor screen, the PC screen turns off, but when I turn on the HDMI on the TV the PC screen does not turn off
Try how?
I can switch desktops by typing “Ctrl + F1” or F2, F3 or more

I did not get it
Here’s what I could do:

If inxi isn’t installed, install it sudo zypper in inxi, then run the two inxi commands.
Follow the inxi command result

After I have run inxi, the TV screen is showing the contents of the desktops, but with a very large size.
When I click on the window icon to display in full screen, the window appears complete
But my icons and the taskbar are still not showing.
What can I do ?
If the TV has multiple HDMI inputs, and one of them is labeled differently from the others, please use the uniquely labeled one for connection to the laptop.
This is the only instance I can remember ever seeing where a laptop display was not enumerated as Monitor-1. It’s a bothersome flag that suggests something isn’t being auto-configured correctly. Xorg.0.log shows that initially the TV is employing its native 1920x1080 mode, but at the end of the log a change has been made to 1360x768, in (trivial) conflict with the TV’s EDID supported mode 1366x768. This tangle might be responsible for toolbar presence at the bottom of a 1920x1080 video buffer matching the native mode of the TV, where it can’t be seen while the TV is running in 136Yx768 mode.
Have you used Plasma’s desktop settings’ display configuration tool to manage your displays? If not, I suggest you try that before anything else. Alt-F2 then systemsettings5 should work if you are unable to access the normal menu icon on the lower left of the main screen.
If display settings doesn’t produce desired results, then log out of Plasma, disconnect the HDMI cable, and reboot the laptop. Before logging in normally, remove all content from ~/.cache/, then login normally. This should give a correctly working single display. Next plug in the HDMI cable, then turn the TV on. What results?
Also, run this, so that if inxi is needed again it won’t complain: sudo zypper in xdpyinfo
Thank you very much, with your instructions I have the PC and TV screens working
However, the TV resolution needs to be at 1920x1080, but when I use this setting the taskbar is cut in half horizontally
How do I solve this problem?
Can you provide a Spectacle screenshot of this cut-in-half taskbar? I’ve seen misplaced taskbar cutting the screen in two, but not a two piece/part taskbar.
To solve this new problem may require you explain which suggestion given produced the solution to your original problem.
I have an idea for a possible solution. Create a file named /etc/X11/xinit/xinitrc.d/50-hdmi-conf.conf with 755 permissions:
sudo touch /etc/X11/xinit/xinitrc.d/50-hdmi-conf.conf
sudo chmod 755 /etc/X11/xinit/xinitrc.d/50-hdmi-conf.conf
Into the file, place the following:
xrandr --output eDP-1 --primary --output HDMI-1 --mode 1920x1080 --right-of eDP-1
This should go into effect when X is next started, if the HDMI connection is live when X is started. Plasma may override it, but let’s see what happens.
Some TVs have an overscan setting you have to tweak/disable, or it will try to show an image slightly larger than the display, cutting the four borders of the image.
