> Like Grigory, I also have my /tmp directory mounted as tmpfs
As I've written I am not having this anymore. Deleting exactly this part
helped me to be able to launch Gnome on Wayland properly.
> Can you share your 'loginctl show-user gdm' and 'loginctl show-session
<GDM session here>' output (before logging in with gdm, you can do this via
ssh or switch to another tty) and your system specs/GPU make?
Sure. The machine is a Thinkpad T480, i5-8350U, UHD Graphics 620 (KBL GT2).

> I've wrote a small guix system test for testing out this tmpfs theory at
https://issues.guix.gnu.org/59739 and so far, all the tests pass, with or
without /tmp as tmpfs mount.
Those tests are good, but I guess the problem is kinda "deeper". I am not
sure but my /tmp dir disappears time-to-time and I don't know the exact
conditions for disappearing for now. Seems like it's a guix pull but it
also sometimes just gone even though I didn't pull. I recommend you to try
deleting this tmpfs part completely and see the result yourself.
