I recently updated to Ubuntu 19.10 and it asked me to set up a key for changing languages recommending me Ctl. + Alt. I accepted without thinking Alt. + Ctl + L is my reformat combo in Intelij and Alt + Ctr + T is my terminal combo. The old language switch combo (Super + Shift) is still active and I much prefer it. Can I delete the new one?
To change the standard shortcuts:
Go to Settings > Devices > Keyboard
Scroll down to "Typing"
Change the current set shortcut into something else.
EDIT: To disable CTRL+ALT (or similar shortcuts for changing language) do the following:
Install the GNOME Tweak Tool
sudo apt-get install gnome-tweak-tool
and open it:
Then go to Keyboard & Mouse and click the button "Addtional Layout Options"
- Look for "Switching to another layout" and click on it.
There you can unselect CTRL+ALT.
