My ubuntu mate 18.04 login window is centered vertically, but is over to the left of center horizontally after Upgrade from 16.04.
Is there anyway to fix this?
That is the way slick greeter works so that is default position now, since it is based on lightdm there maybe a config file way but I'm not aware of any maybe someone else can comment if there is a way
Never mind I found it
System --> LightDM GTK+ Greeter Settings
And you can edit position in there
Ok I looked but did not see it
To moderators if they see this; disregard some of my report, I didn't know what I was talking about but still, make it so @Spankalish' answer to his own problem is a solution.
I had the same problem. That's because it's at
System --> Administration --> LightDM GTK+ Greeter Settings
