Chris,
I’m not familiar with your exact hardware/OS description but I have run Lightburn on Intel Chromebooks for years. In your Chromebook’s “Advanced Settings”, you have to enable “Developer Mode” to enable the Linux developer environment, the “real” Linux underneath. For me, that’s always some flavor of Debian Linux.
I’ve got a thread that addresses the last time I installed Lightburn on a Chromebook and the library issues that popped up… that was on Debian10 (Buster) and Debian11 (Bullseye). I’m running an Acer Intel I5 Chromebook with Debian12 (Bookworm) now but really can’t recall having any issues at all with LB installation. Check out this post and see if any of it looks familiar to you… but first enable developer mode (if you haven’t already) and download the latest Lightburn .run file (remember to move it to your home directory first). Then follow the command line prompts to verify the installation and run Lightburn… and expose any issues.
Hope this helps.
