Some Multimedia Keys Not Registering in Linux

Description:

PrevTrack, NextTrack, and PlayPause keypresses elicit no response from Renoise in Ubuntu Studio.

Steps to reproduce look like this:

In Windows, bind Global>Transport>Pause/Continue (from cursor) to “PlayPause”
Export keybinds.xml file
Import keybinds.xml file to your Ubuntu Studio copy of Renoise using a thumb drive
Launch Renoise in Ubuntu Studio
Press “PlayPause”

Expected results:

The default song is played.

Actual results:

The playhead does not move.

The same goes for PrevTrack and NextTrack, which I have bound to Pattern Editor>Navigation>Jump to First/Last Row, respectively.

I can’t rebind anything to those multimedia keys in my Linux copy of Renoise or get any sign that the program is hearing the keypresses, whether I check “Override window manager shortcuts” or not.

The multimedia keys work as expected in VLC Media Player and Firefox, playing, pausing, and skipping through playlists.

I’m running Renoise 3.4 in Ubuntu Studio 24.10 on an Acer Nitro 17. I imported my keybinds (and my user library, etc) from Windows 11. Below are my media key shortcut settings in Ubuntu Studio (defaults). New linux user here, so be gentle!
