Guix OS + Wayland + Gnome Questions

Guix OS + Wayland + Gnome Questions

Hello!

I run Wayland + Gnome on my Guix OS. (See attached files for detailed 
configuration)

Q1. How do I Lock Screen?

Q2. How do I take Screenshots?

Q3. Should I not bother with Wayland and use X11 (or whatever that's 
called that is the default)?     I started to use Wayland because there 
was significant lag in repeated (that happens automatically when a key 
is pressed for a few seconds)  keystrokes in terminal applications.

Many thanks in advance!

I just went back from Wayland to X11 because with Gnome this all feels
too buggy.  I had constantly shifting window frames when switching
windows, screen blanking whenever I’d watch a video with mpv for long
enough, could not use the Gnome screen keyboard, and was no longer able
to use peek for recording videos.
