Here is what I had to do to make Lightburn on Linux work. I’m on Arch Linux with kernel 5.6.15.
An error I encountered was:
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
export QT_DEBUG_PLUGINS=1 and running LightBurn again, I noticed there were complaints about not being able to find 'libxkbcommon-blah*. The fix was as simple as
pacman -S libxkbcommon-x11. On Ubuntu, it would be something like
sudo apt-get install libxkbcommon-x11-0
For the developers, I would highly recommend doing a fully static compile or a flatpak/docker container of some sort to make it easier to “launch”. I know most use Windows, but there is a large community behind Linux. Thanks for making a suckless product!
