I have a laptop with an nVidia RTX 2080 and the
440.64 driver. I have both
gdm3 installed and am running Ubuntu 20.04 which means as of today I have just about the latest hardware, operating system and drivers.
My setup is one Dell G7 laptop and one external Dell 4k monitor connected to the miniDP port on the back of my laptop.
When I activate
lightdm I have, in the extended login menu options, the option to use Ubuntu on Wayland.
Selecting this option and logging it only shows the desktop on the builtin monitor.
echo $XDG_SESSION_TYPE shows
However, nothing I can do allows content on my external monitor. It is not detected by the “displays” option in setting (although unplugging and plugging it in does cause my attached monitor to blink).
gdm3 and there is no gear / login settings that allows me to choose wayland.
/etc/gdm3/custom.conf file shows wayland to be enabled. i.e. contents are :
# GDM configuration storage # # See /usr/share/gdm/gdm.schemas for a list of available options. [daemon] # Uncomment the line below to force the login screen to use Xorg #WaylandEnable=false # Enabling automatic login # AutomaticLoginEnable = true # AutomaticLogin = user1 # Enabling timed login # TimedLoginEnable = true # TimedLogin = user1 # TimedLoginDelay = 10 [security] [xdmcp] [chooser] [debug] # Uncomment the line below to turn on debugging # More verbose logs # Additionally lets the X server dump core if it crashes #Enable=true
So two questions:
Why isn’t this (running Wayland) working? The amount of research required to investigate this is significant.
As of today, using nVidia hardware, is there any possible configuration that allows Wayland to work (with necessary features like multiple monitors)
