I am on the brink of going nuts because certain keys are not working properly. The keys in question: g, h, ø and the up-arrow. The weird thing, though, is that they do work for some 5 seconds if - and only if - I first hit the Alt-key (which allows me to write this). It’s only this key that somehow allows those keys to work for some few seconds.
I have searched and searched, but not found a solution. System is updated. I have tried to switch kernel. Also, in time this new dysfunction seems to me to have come about after I switched from 510 to 515. After switching back to 510 this issue is not resolved, though.
Here some more info:

Thanks for reading. Are there some wizards around to help me out?
