This is due to logind not implemented in mir yet. but a workaround for this is to give permission to your user. This is just a workaround, and you are modifying the permission. this workaround does not persist if you reboot and may even reset if you login to another desktop environment.

1. When you're at lightdm, go to a tty (ctrl+alt+f2)
2. login
3. then change the owner of /dev/input/ and /dev/tty (number can be different from dm's, lightdm i think is tty8 (for the wayland session), but if you use it will chown all of them)

   sudo chown -R $USER /dev/input
   sudo chown $USER /dev/tty*

4. go back to lightdm (ctrl+alt+f7 or ctrl+f7)
5. login to unity8

[pixelr0]

nope, still the same error

the only way i managed to start unity8

sudo chown -R $USER /dev/input

Same here! Not logging in. Just returns to the login screen after correct password.

[pixelr0]

new mir 0.32.0 landed in ubports repo with logind support. can you update and try to login again?

[pixelr0]

for now you have to login twice in order to work, first time will bounce back to the login screen and second time will load
