Linux Cannot login to Mint Os.

6pack

ex-Mod
I have Linux Mint installed on a nokia laptop. Keyboard is automatically typing the [ key at full speed right during startup. I can see the line of [[[[[[ typed after grub boots. This nonsense started suddenly this morning. When the login screen appears the key types automatically and i have to press escape key multiple times to clear the password field. No matter what i try, i couldn't login.
Is the keyboard gone bad or is this a software problem?

I tried searching for nokia purebook laptop keyboard but results are from Alibaba or Amazon dot com. Is there a way to use the laptop with internal keyboard disabled and use external wifi keyboard?
 
Dunno why, but this seems to be a regular problem with laptops. In my case, this has always been a problem with keyboards. Could this be caused by dust getting trapped under the key ?

Try to press each key multiple times and see if this helps.
If you are able to login eventually, you could try disabling the internal keyboard and connect an external one. if problem goes away, then that will confirm it.
