Running WSL2, Ubuntu 20.04, systemd genie; everything installed and launches without issue. gdm, however, runs only as root, even though /etc/gdm3/custom.conf explicitly sets User=gdm and Group=gdm. Is this intended? If not, how can I fix it?
(The issue that got me here: When gdm locks the display after inactivity, it accepts my password but never lets me back in — no matter how many times I enter it, gdm cycles back to the password screen. I suspect a file permission problem.)
