After changing the gtk-theme in the GNOME Tweak Tool, I was taken out of the session to the login screen and now I cannot log in. I can only log in using the guest account.
So in the grub menu I selected the recovery mode and in the resulting menu I selected root-drop to root shell prompt. Once there I did a couple of things I've found in several pages and in the forums.
gsettings reset org.gnome.desktop.interface gtk-theme
This is what I got:
**(process:642):WARNING**: Command line 'dbus-launch –autolunch=4438d024dd45ef7fb2d3f4ab0000000f –binary-syntax --close-stderr' exited with non-zero exit status 1: Autolaunch error: X11 initialization failed.\n
and nothing changes.
gconftool-2 --type=string -s /desktop/gnome/interface/gtk_theme Radiance
With this I was trying to change the gtk theme to the Radiance one. No strange message this time but it did not work either. I still cannot log in.
Any ideas please?
