Amazing, I just tried your script on UbuntuStudio and it worked so far. Small caveat: as soon as I left-click somewhere on the Desktop the image disappears, the script is still running though. But this is probably related to the different DE. No need to improve the script if works on plain Ubuntu, I was just curious if it would work on my system too, upvoted... Have a nice day!

@mook765 ah, that is interesting, and probably easily fixable. Do you have wmctrl installed? If so, does the window still appear in wmctrl -l ?

@mook765 Added one line, does that make a difference?

wmctrl was not installed, so I installed it. The window is is listed with 0x03400003 -1 MookPC PortraitonMyDesktop and stay listed even when the Window disappeared.

Now the Window will stay allways on top.

@mook765 Ah, great! Thanks for testing and confirming :)

...present

@mook765 ^

I was to fast with the last comment, the window does not disappear anymore, but now it stay always on top of other windows.

There is another option, to set the window as a "normal" window, but keep below all other windows. The downside is that stuff on the desktop (folders) will appear below the window.

@mook765

Cool, thanks! I don't have xfce atm, but will try if I have the opportunity :)

I guess you have more things on your to-do list, so I think we stop the discussion at this point, perhaps we meet another day here on AskUbuntu. I read a lot here and stumbled about your name many times. Thank you so much for sharing your knowledge with the community, I wish I could help as much as you...

@JacobVlijm, I upvoted your nice little script too :-)

@sudodus thanks :)

Please advice where to learn programming python. (I am rather good at bash, and long ago I programmed Fortran and C, so I can stand some difficulties.)

@sudodus The thing is, I don' t remember exactly how I started. It was with a very simple tutorial which I couldn' t find back later. Then started a simple project, constantly using Stack Overflow to look up things. Not really much of a help I am afraid :)

OK. I will look for tutorials via the internet. I think you are right, starting with a simple project is a good idea.
