Switching from LightDM to GDM

Yesterday, when I updated my Antergos box, it pulled down lots of shiny new Gnome stuff. Today, when I booted up my laptop, I discovered that the greeter wasn’t working any more and I couldn’t sign in or get at any of that shiny new Gnome stuff.

I have encountered this issue before and it was caused by the Antergos LightDM greeter theme. The easiest solution, therefore, is to switch to GDM so that I am using all Gnome all of the time.

It’s a painless enough process, but I am recording the steps here so I can easily look up the steps when I need them again.

So…

CTRL-ALT-F2 to get into TTY2

Log in and switch to root. Then…

systemctl stop lightdm
systemctl disable lightdm
pacman -S gdm
systemctl enable gdm
systemctl start gdm

And you’re done.

Update

And I notice today (Friday 14th) that I now have an updated lightdm-webkit2-greeter which probably solves yesterday’s issue. That said, I will stick with GDM for now just to see how things go.
