If your “switch user” is not working (blank screen and freeze):

$ vim /etc/gdm/custom.conf Uncomment the line: WaylandEnable = False

Restore touchpad configuration (on and off) on gnome 3.20 (Arch Linux):

$ sudo pacman -Rd xf86-input-synaptics $ sudo rm /etc/X11/xorg.conf.d/50-synaptics.conf $ sudo pacman -S xf86-input-libinput (logout and login again)

Login to Gnome keeps getting back to GDM on upgrade to gnome 3.28

I had a situation where after upgrading to gnome 3.28 when trying to login on gdm it started and came back to the user selection screen. The culprit from where I found on Reddit was some of the extensions. To discover the problem: $ journalctl -b -p 3 Then, I just renamed ~/.local/share/gnome-shell/extensions to ~/.local/share/gnome-shell/extensions.OLD and I was able to login again, I just had to reinstall them from the epiphany browser from extensions.gnome.org.

Material Design theme:

packer -S materia-theme gtk-engine-murrine gnome-themes-extra --noconfirm

gnome-control-center timeout errors after upgrade to gnome 3.28

Just kill the process and start it again, manually or from the menus:

$ kilall gnome-control-center
$ gnome-control-center &

change ubuntu gdm login theme:

Edit file sudo vim /usr/share/gnome-shell/theme/ubuntu.css and then section “lockDialogGroup”. E.g.:

#lockDialogGroup {
background: #063c27 url(file:///storage/s3/temp/curated/space/NGC6914_Eder.png);
background-repeat: no-repeat;
background-position: center; }
