[Lubuntu-admins] [Bug 1712089] Re: Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused
"Wayland" doesn't appear to care how many bugs they have created with
their philosophical decision to not allow actions like "sudo synaptic"
starting a graphical application from the command line. Is there any
rationale??
Thanks, Jerry

Posting here what gnome says about porting to wayland, and their
tests:
GNOME Applications under Wayland
GTK+ has a Wayland backend. If it was enabled at compile-time, you can run a GTK+ application under Wayland simply by:
GDK_BACKEND=wayland gnome-calculator
Applications that use Clutter or clutter-gtk also need the Clutter Wayland backend enabled:
GDK_BACKEND=wayland CLUTTER_BACKEND=wayland cheese
https://wiki.gnome.org/Initiatives/Wayland/Applications
======> so hope the settings are well set at compile time; maybe a
rebuilt to get sure all apps are ok.

With the today packages upgrade, switching from X11 to wayland,

sudo synaptic
[sudo] password for oem:

Previous days already have switching some packages to wayland, but

cold reboot, that synaptic gui is broken.
