[Cuis-dev] VM fb-dev

[Joseph Turco]

Yeah as I said I get black borders around the window buttons, and it looks like its running in 16bit mode because the color of the windows have visible color gradients. Using raspberry pi os 64 bit which is a flavor of Debian.

Regards,

Joseph Turco.

The mouse works, but the keyboard is still typing into console, with a cursor flashing in the bottom left of the screen (like a bit of the console is poking out). If you have any advice to fix that I'd appreciate it many thanks :)

I'll have to fire up a RasPi to check. .. Nope.  Looks good on Raspberry Pi 3 on Raspberry Pi OS.  No idea.  Have to look around.

Useful when I forget and fire up a framebuffer display which takes turns overwriting with X11 if I have started that as well.
