ohai.

so I tried to start into "wayland" session but the option is not there
the only options are "Gonome on Xorg". "Gnome Classic" and "Ubuntu" - all three run xorg - no wayland.
$ echo $XDG_SESSION_TYPE
x11

None of these three can run a joined display. Mirror (2 x 1080p) works well.
Also Extending the screen when running the screen in non-native (1080p) works.

so I started experimenting - used a different hdmi cable (1.4 with ethernet) but same
also used a HDMI to DP adapter and connected that - nothing.
then I tried running the screen as a "single" display - that also failed,

Now, I am running the proprietary nvidia driver (so I can switch intel and nvidia, I think it's called PRIME) - I switched to Intel only but same. Can't run the screen in QHD resolution, be it joined or single.

hope this helps someone. I'll wait for a new driver/fix/kernel/ubuntu release (20 April still go? ) :)

UPDATE 26 April

updated to Ubuntu 20.04 and still same.
mirror and joined works in xorg and wayland (same)
but the screen does not work in QHD (2560x1440) in either display manager and not as "single display" either.
both in "intel only" and "nvidia" mode. (prime)
using proprietary driver I can choose. nouveau does not allow me to chose, also doesn't work in QHD.

anything I can do to help?

cheers and thanks for all the work
