#LinuxMobile Played a bit with example of #GTK4 tutorial and #Cairo, to have a light/ basic drawing/note application on my #LinuxPhone.
8 colours (Oric/Spectrum style KRGBCMYW palette) until a palette definition tool
2 modes: dynamic (tested several possibilities, made this one for the demo) or uniform line (need to add a thickness setting).
no save or anything, it’s like a Télécran (english name:”Etch A Sketch“）for now. It’s pure compiled C, and very simple, code, but it is already really slow, far under the capabilities of the device. Don’t know why for. Maybe linked to screen event? It is very smooth on my 10+ years old desktop computer.

There is also a section about my PineTime talk in the article at root.cz (probably readable with DeepL).

@lupyuen -- did you try the iwlwifi driver for wireless? It should be better than wifibox. Which is kinda hacky. Like your Wayland + sway setup. Still, you'll take X11/i3 out of my cold dead hands. It's as stable as a rock. So is BSD as a whole. It can take some puttering to get things right, but once it's working, it is good for years. Rarely see a break in software when using RELEASE and quarterly updates for ports.
