What desktop environment do you use?

KDE

Environment xrdp running on

What's your client?

mstsc.exe on Windows 11

Area(s) with issue?

Keyboard / Mouse

Steps to reproduce

1. Configure KDE Plasma session (plasma version >= 5.8) such that it has an application launcher, with a global shortcut assigned.
2. Sign in on the physical machine and start the Plasma session. Press the meta key on the keyboard. It should start the application launcher.
3. Sign out the session on the physical machine.
4. Configure the RDP client to handle special keys on the remote machine. Sign in through RDP to the Xrdp server on the same machine, and start the same Plasma session.
5. Attempt to press the meta key to start the application launcher.

✔️ Expected Behavior

The application launcher shows, in the same way as signing in through the physical console.

❌ Actual Behavior

Nothing happens.

Anything else?

The meta key registers as part of a hotkey combination normally in shortcut settings.

Hi @miklcct

By the 'meta key' I assume you mean the Windows key?

First thing to check is the client settings 'Apply Windows key combinations':-

I think the default is 'Only when using the full screen'.

If that's not it, run xev in the session and see what kind of key events you're getting from the key.

[miklcct]

Yes, it is applied in the remote machine. Combinations such as meta+F1 works.

Same issue here (on Kubuntu). Using correct RDP settings in windows and I'm fullscreen (ALT+Tab works!)

When login locally, xev gives keycode "133" for the meta key When login using xrdp, xev gives keycode "115".

When setting the "Activate Application Launcher Widget" shortcut, it does allow me to set the "Meta" key. But it shows gibberish.

This is in ~/.config/kglobalshortcutsrc when adding the meta key as an additional shortcut (logged in using xrdp):

activate widget 3=ៀ?\tAlt+F1,none,Activate Application Launcher Widget

Maybe this info helps

edit: I did not touch any xrdp keyboard remaps and I'm using a default us keyboard
