I am a new in Ubuntu and still learning to use it. But in some ways I get the error as below and I can't Google it to find an answer. If someone please see this error:
Error activating XKB configuration.
There can be various reasons for that.
If you report this situation as a bug, include the results of
xprop -root | grep XKB
gsettings get org.gnome.libgnomekbd.keyboard model
gsettings get org.gnome.libgnomekbd.keyboard layouts
gsettings get org.gnome.libgnomekbd.keyboard options
