I am using the GTK greeter for LightDM but the cursor looks very tiny on my laptop's 1080 display. I have already set the DPI setting and some text looks big, but the center input is still small and the cursor remains small, too. I followed some instructions here which advice to use
dconf as root, but doing:
dconf write /org/gnome/desktop/interface/cursor-size 32
fails saying that the connection is closed.
Also, I found out that root isn't supposed to use
dconf. I tried
dconf-editor with the same results, and
/etc/gtk-3.0 doesn't even exist in my system (Fedora 29). What can I do?
