  • Open terminal and enter this command. 'sudo dpkg-reconfigure keyboard-configuration' Select the correct layout. Hope it works – A Umar Mukthar May 11 '20 at 05:29

  • Please post the output of : uname -a . – abu_bua May 14 '20 at 23:58
  • Those are the special function keys. They can be hardware specific. If those keys are not specified in the hardware then they may not work. Make sure they are enabled in the Bios as well. Some Bios(Microsoft Surface for example) control some of that in the bios. – walttheboss May 15 '20 at 00:06
