I'll tell my Mom that she can use "startx -- :1" followed by Ctl-Alt Fn to switch" instead of her mouse. I will also tell her that ext4 and btrfs are in Fedora and she wil be so happy she will cook a cake for me.
Ok, Kudos for Fedora for this audacious step, it is a good thing. Kudos for Ubuntu for putting efforts in the notification system. It is needed too.
