I just installed Ubuntu 14.04 LTS in 2015/10/5 alongside windows 8. The keyboard seems to working fine except the ctrl,alt and probably other that I couldn't tell without those button. I cant even copy and paste without them. I tried changing the keyboard shortcuts in settings but everytime I try setting to ctrl + something it warns be back saying "don't use shift + something". Can anyone help? is it the layout or something?
FYI: all controls are normal in windows. Also, for a first timer Linux user this is too overwhelming, just encountered 5 errors in 2 days. This one is clearly major issue.
