[ubuntu-studio-users] Ver 22.04 Desktop (KDE) does not seem to allow for images spanning multiple screens

Hi Dave

Yes, I noticed that you can load individual images on each monitor, but 
I didn't want that. With wide graphics made for multiple monitors 
already on my hard drive, that is still a big let-down. KDE was not the 
desktop supported by the last LTS of ubuntu studio, since it worked 
before my upgrade. If I recall I was using xfce, which had the support. 
Both monitors are identical LG monitors; both identified as model 
16843009 by the KDE display configuration settings.

On another mailing list, someone suggested this 3rd party executable, 
which is not the most perfect solution, but it does the job:
https://github.com/hhannine/superpaper

For Ubuntu, a superpaper binary which they called an "AppImage" format 
was on offer, and I downloaded it. It is a zero-installation solution, 
allowing me to chmod and execute the binary in-place and try it out.

The GUI responded in a funny way to me: things which acted like buttons 
didn't look like buttons (in fact checkbox and textbox widgets appeared 
missing, but would do the expected thing if you clicked), but I 
eventually figured things out, and it is doing its job. But once you 
close the GUI, the program stays in memory on the command line. And it 
is there I found a flurry of warnings from GLib and GTK. Pressing 
Control+C to return to the command line resulted in the image still 
residing in memory.

Obviously, I will need to view the docs in more detail.

I suppose if I want things like the GUI to work properly, I should 
download the source code, which is on offer where I downloaded the 
AppImage.
