--- Comment #3 from Mario Kleiner <mario.klei...@tuebingen.mpg.de> ---
This is running the new GNOME based Ubuntu GUI with Gnome-Shell Wayland, right?
With "Windows control did not work" you mean it doesn't respond to
mouse-clicks?
In that case it is known bugs/limitations in gnome-shell for depth 30/10bpc
mode. GNOME Shells picking code can't handle 10 bit per color channel.
Additionally Gnome-Shells Wayland compositor doesn't handle anything but
bgrx8888 or bgra8888 framebuffers in its drm/kms backend. It takes whatever
framebuffer format it gets, e.g., bgrx1010102 and hands it to the kernel as
bgrx8888, so the gpu misinterprets a 10 bit image as a 8 bit image during
scanout, which ends badly.
