Rack 2 File Manager Issues Linux

Using VCV Rack 2 (Free 2.0.6) on an Arch Linux system and the program is unable to open any file manager windows for saving/opening files, instead freezing the GUI for a few seconds before resuming. Autosave works just fine. Following is the log error resulting from the File->Save option:

My active file manager at the moment is PCManFM and I’ll be trying out a couple different ones in a bit.

It doesn’t call a file manager like PCManFM or Dolphin, but rather a file picker. I would guess that you don’t have xdg-desktop-portal installed/set up.


I think it requires Zenity to be installed.

Iirc Zenity is for notifications, not for file-browsing.

[edit: apparently it also has a file selection dialog. I would also expect this to just be chosen by xdg-desktop-portal, though]

I installed xdg-desktop-portal and its GTK backend, with zenity for good measure and I’ve got it working just fine now. Thank you both so much.
