van_Zeller, set up a desktop shortcut to setxkbmap.
In Gnome, right-click the desktop and select "Create launcher"
In KDE, right-click the desktop and select "Create new" - "Link to application"
Then when you have the problem, just select an empty desktop (assuming you have more than one and leave at lease one empty) and click your setxkbmap icon.
