I have been a SuSe user for over 4 years now and recently upgraded to SuSe 12 from 10.3. All installations are MidSum checked.
I have always had a problem with the " key typing th @ key instead (Only since SuSe 10.3 - not in previous Fedora distros - sorry “flavours”).
I think there’s a few other non-letter keys too but I use them rarely. I have tried 3 types of keyboard - all different brands all with the same problem.
Currently I am using a genuine Microsoft Digital Media Keyboard -3000-v1.0. I have Num Lock on, Fkeys are working. I have tried USB and PS2 connections but they are all the same.
The SuSe installations is set on English US and no other languages are used on this computer.
(I also have a second problem with a printer but I’ll list that separately - I don’t think it’s related to this).
