Xubutnu xfwm4 window tiling shortcuts not working as expected

[Daniel Papp]

Testing Xubuntu 22.04, using xfwm4 4.16.1-1. It's a regression from Xubutnu 21.10. It can be easily reproduced with a livecd. Altough window tiling shortcuts are seemingly correct in window manager settings a few act weirdly. Precisely:
Super + Up does nothing
Super + right does nothing
Super + down (numeric) moves the window UP (most weird)
Super + left (numeric) does nothing
Super + up (numeric) does nothing
All other tiling shortcuts works as expected. (Super +left, Super + down, Super + numeric right, super + numeric 1,3,7,9)

Another weird thing, if I edit the shortcut "Tile window to the top" to Super + Up, so same as before, it starts working, but the fix seems not permanent.

The same happened to mi brand new xubuntu installation. Looks like the default shortcuts on the Window Manager Keyboard Settings are conflicting.
At first Tiling only worked to super+left and super+down, but not right or up.
While checking the shortcuts, I noticed the Numeric Pad ones are backwards:
Super+(Right arrow) and Super+(Numeric Pad Left arrow) are used for the same
Also with down arrow and up numeric pad.

The fix is easy and permanent, just reconfigure the shortcuts and remove the conflict.

checking /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml all seems fine, only arrows and corner KP_{1,3,7,9} are assigned, thats odd!

Status changed to 'Confirmed' because the bug affects multiple users.

[Sebastian Benvenuti (sebastianbenvenuti)]

It seems to me that these files in /etc/xdg are concatenated to create the user config, creating conflicting duplicates. Plus, a couple are upside-down.

Either clearing the conflicting lines in one of them, preferably the /etc/xdg/xfce4 one so we keep the Xubuntu customization intact, or using a script to combine them with prioritized de-duplication in mind should do the trick.

In any case, there are wrongly assigned keys (up per down and viceversa)

That's why manually changing the shortcuts is a permanent (per user) fix.

Let's make Xubuntu better together! :-)
