Unable to get the Editor working on Linux - Fedora KDE

Midihub Support
1

Hello. I don’t seem to be able to get the Midihub Editor working at all on my laptop which is running Linux currently. I downloaded the appimage and tried to launch with Gear Lever but nothing happens. I also tried the method on the Fedora Wiki for running appimages but nothing happens.

I’ve got absolutely no clue how to resolve it, any help would be appreciated.

Thanks.

What output do you get if you start it in a terminal / console?

This seems similar to Can't launch Midihub Editor in Wayland session

Try starting it like this:

QT_QPA_PLATFORM=xcb ./MidihubEditor_1.15.3.AppImage

Yeah that seems to work. Would be great if I didn’t have to do that of course, but I’m glad that I can use the editor on Linux at least.

Thanks.

Ah, thank you, I had the same issue under KDE Neon (based on Ubuntu 24.04 + up to date KDE stack) !
