Hello! The issue occurs in LightDM login screen, the LXQt version.
I unput my login-pw as per usual, get a black screen for a second and back to the Greeter.
This happened after software upgrade via pamac.
I have GRUB upon boot options and a win7 partition as an option on the same hdd. Is installing Antergos from a live usb media a way to solve this issue?
Edit: as I recall the day of the update the system would not shut down for a long time so I sudo shutdown now. Maybe this had something to do.
