I have installed linux appimage 1.6.0. All is working fine after some tuning, I can open files, I can drag and drop files to lightburn but i cant open lbrn2 files with double click, they are associated and when I click lightburn start to run, but i get a screen message:
The file XXXXX.lbrn2 cant be opened
I have tried different source files on differents paths, same file can be opened from menu or drag and dropped.
If you rename the AppImage to LightBurn.AppImage you can update by renaming the new version and replacing it with the old one without having to edit with alacarte.
Or you can right click on a lbrn2 file, select open with, down near the bottom should be other applications, select it, choose the Always open with checkbox, and select lightburn as the application to use. Usually or at least on debian, it’s under graphics.
Appimage are moved to home/appimage and integrated by Gear Lever program, file type registration is working, i can do doubleclick to lbrn2 and then ligthburn is opened. I have seen this before with flatpak and it can be solved using flatseal to give access to sandboxed app to user files path, but i dont know how to make this for appimage
This really is something based on your Linux distribution or your choice of desktop.
There should be a tool for your distribution which sets the mime-type for applications and files and associates the file with the application(appimage).
Those should allow you to setup if drag-n-drop work and opening up the source file(lbrn2) directly.
BTW, this is really desktop specific so you might also look at your linux distribution’s online forums, reddit, etc for into since it’s not specific to LightBurn.
