I am facing a problem with my backslash. whenever i press control backslash this (#) comes out. I tried to press alt right that doesn't work as well. Initially everything was working perfect this happened after removing the debug port. If anyone knows the solution please try to help me as i am writing my dissertation on latex and this key is really crucial.


  • Have you checked your keyboard layout? Open System Settings > Keyboard Layout – Quaxton Hale Mar 12 '14 at 21:58

It's just a keyboard configuration issue. Your computer assumes your keyboard is American but it's actually British (or something else with that crossover). It's fairly simlpe to fix from a terminal:

sudo dpkg-reconfigure keyboard-configuration
