After a long 11+ years of Ubuntu, openSuse, Windows 10 mixed usage, I got attracted to "elementary OS". Hence installed it on my laptop. Was working fine for first few days. Day by day I started notice that the numeric keys on top "1" through "4", the alphabet key "p" and the "backspace" keys were out of working. Not that they never worked. They go out of working intermittently. Suddenly works, when even on certain times I hardly press them (this I really do not understand). I tried changing the input methods, regional settings, keyboard settings, etc. Nothing seems to be solving this difficulty. Even typing this question took me 16 minutes (I counted it). If someone could solve this impediment, I will thank them by recording their name in my local contact store. Please help & thanks in advance.
Quick question: 1) Check if you have num lock on (that caught me out on my laptop ) 2) What keyboard do you have? I think Code (Text): setxkbmap -query is the right command to find your keyboard type, please post the result here.
