Running Mint Tricia on my laptop when left hand side of keyboard stopped working. Couldn't even log in, so I bought a wired keyboard to access. Ended up re-installing Mint. Once done, I got my full laptop keyboard back. Any idea why I might have lost half the keyboard, or a suggestion to fix without re-installing? I'm a linux newbie and only a casual computer user starting to teach myself linux. Thank you for taking a look at my question!
Might be that the wrong layout got selected, you can change this with Code: sudo dpkg-reconfigure keyboard-configuration
