I can't bind the CTRL+ALT+BACKSPACE shortcut to Plasma "logout without confirmation", the backspace key does not seem to be detected when associated with ALT+CTRL (while other combinations, for example: CTRL+META+BACKSPACE, are correctly detected).

I cannot reproduce this. It could be that your keyboard does not support this combination of keys. Try this website: https://www.mechanical-keyboard.org/key-rollover-test/

Try this website: > https://www.mechanical-keyboard.org/key-rollover-test/ The test was helpful because the "backspace" key is detected as "unidentified" (ctrl,alt,unidentified), even though it still detects the sequence of three pressed keys. However it can't be a keyboard problem, because it was working end a month or two ago (I couldn't tell you the exact version of plasma/framework from which it stopped working). It can't even be a distribution-specific issue since a couple of them have the problem. I think one of the plasma updates created the problem.

Can you clarify where exactly you're trying to set this shortcut? Is it on System Settings' Shortcuts page?
(In reply to Nate Graham from comment #5) > Can you clarify where exactly you're trying to set this shortcut? Is it on > System Settings' Shortcuts page? Yes, I open "systemsettings" and select: - Keyboard - Shortcuts - Session Management - "exit without confirm" - button "add custom shortcut" - press "ALT+CTRL+BACKSPACE" but only ALT+CTRL is shown on the screen, BACKSPACE is not ignored (as if I had not pressed it). However, if I try other combinations, for example: CTRL+SHIFT+BACKSPACE, META+SHIFT+BACKSPACE, ALT+META+BACKSPACE, ALT+SHIFT+BACKSPACE, they are recognized correctly and accepted. Before the problem occurred I had already set this shortcut with the indicated sequence and it worked fine; for some time I noticed that this shortcut did not work anymore, so I went back to the shortcuts page and nothing had changed, the screen always showed CTRL+ALT+BACKSPACE, even if it did not work. So I tried to reset it again, but I noticed it no longer accepted this combination.
I can successfully set that combination on my system FWIW.
For a simple test you can also try with OpenSuse live (from: https://download.opensuse.org/download/distribution/openSUSE-current/live/openSUSE-Leap-15.6-KDE-Live-x86_64-Build13.327-Media.iso): - start iso - system settings - switch to sidebar view button - shortcuts - ksmserver - log out without confirmation - add custom shortcuts button - press: ALT+CTRL+BACKSPACE same problem, the third key pressed, "backspace", is not detected and there is a different version of kde/framework: Operating System: openSUSE Leap 15.6 KDE Plasma Version: 5.27.11 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.12 Kernel Version: 6.4.0-150600.23.17-default (64-bit) maybe it could be an indirect problem generated by a library
