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!
