Fedora + Phosh for PinePhone

[nas]

gdm didn't work as it just gave me a virtual terminal (obviously no onscreen keyboard there.)

I missed a couple steps before disabling the phosh service - you can select the keyboard from accessibility button at top right on gdm login but will be oversized unless rescaled beforehand.

gsettings set org.gnome.desktop.interface scaling-factor 1
sudo systemctl enable gdm.service -f

lightdm seems so close- I followed the instructions in your other post and I'm at the login screen, but I can't get the virtual keyboard to come up.

For lightdm, I would say to check you installed the onboard keyboard package.

dnf install onboard
