keyboard alt,shift,ctrl keys don't work

Post by israelelad1 » Sat Oct 20, 2018 5:12 pm

hi!
i'm new at linux, using latest mint cinammon 64bit dual boot with windows.
So, whenever i use my laptop regularly everything works fine, but when i try to use my external keyboard(when i use a bigger monitor etc..), the ctrl, alt, shift and possibly more keys don't work.
well, i think they do work, because in the terminal i can see the cursor shape changes as if i pressed a button, but nothing else happends.
so i can't change language, copy paste.. you get the idea. annoying.
Help would be appriciated!

p.s: i followed this guide: viewtopic.php?t=247313
to make my mouse buttons execute ctrl+c and ctrl+v.. maybe that's connected somehow.
thanks!

If you boot from the Mint DVD (or live-USB) into a live session, does your external keyboard then work as it should?

i'll check.
in the meanwhile, i did find a topic i think is related to my problem:
with xinput all the keys that don't work are all registered as key "50". whatever that means.
tried this: https://askubuntu.com/questions/648798/ ... s-as-shift
and my keyboard stopped working completely after step 1(other steps didn't help). had to use timeshift..

hey friend,
I think When the keys on a keyboard don't work, it's usually due to mechanical failure. If this is the case, the keyboard needs to be replaced. However, sometimes non-functioning keys can be fixed. It is likely that the keyboard is defective and needs to be replaced.

What's the type of keyboard you have chosen while installing Mint?
