DataDrake torty_tum One more thing to try first. I think you also need to install slick-greeter. It would have been removed when you first uninstalled lightdm. Please see if that works with a reboot after.
WetGeek DataDrake You would need to switch it back if you wish to use GNOME again. Simpler just to change to Budgie, no?
DataDrake WetGeek My point was I asked them to uninstall gdm which GNOME needs to run. They would need to uninstall lightdm and reinstall gdm if they want to go back to GNOME from MATE.
