I used to use CTRL+Super+arrow to resize my windows to a particular side of the screen. But since a fresh install this doesn't work any more. Has anything changed? I cannot remember manually adding these shortcuts.

  • Did you change to a different version / flavor of Ubuntu? What version / flavor are you using now? (And which were you using before if you changed?) – Zanna Mar 22 '18 at 14:06
  • Would it be that you need to install Compiz Config Settings Manager? – DK Bose Mar 22 '18 at 16:31

My problem was just a switch on the keyboard that was in "Gaming Mode". Anyway sometimes this issue comes from another problem so here i explain how to fix this issue :

In terminal :

dpkg --get-selections | grep -i compiz
sudo apt-get install compiz compiz-core compiz-gnome compiz-plugins-default compizconfig-settings-manager libcompizconfig0 python-compizconfig --reinstall 

This will fix most issues with keyboard shortcuts.


Sometimes you still have keyboard/shortcuts issues. Then there are few options left:

1. First Start with Unplugging your keyboard and plug it back in.

2. Reinstall/Reinitialize your keyboard layout :

In terminal :

sudo apt-get install console-data
sudo dpkg-reconfigure console-data

Or use :

dpkg-reconfigure keyboard-configuration

Through the graphical interface :

  • Click the Settings menu > System Settings:
  • Next, go to Personal > Text Entry:
  • Click the + button to choose a new layout:

3. Use onscreen keyboard to test if the shortcuts work there :

You can think why not try this first ? Well basically because this is not the first thing that comes up when my keyboard don't work since it should work.

In terminal type:

onboard

Through the graphical interface :

  • Click the Settings menu > System Settings.
  • Next, go to System > Universal Access.
  • Select the Typing tab, and then switch the On-Screen Keyboard option to ON.
