Well, my keyboard doesn't work on ubuntu if I run it on kernel 3.11 at the start-up screen
there are error messages: atkbd serio0 failed to enable keyboard on isa0060/serio0
Found a fix! Launch this app called 'dconf editor'. Open Desktop -> ibus -> and click on General. Now check the box next to 'use-global-engine' and 'use-system-keyboard-layout'. This worked for me!
The upgrade failed and i cannot type at the console. I tried booting from the 13.10 installation media and the keyboard does not work there as well. Is there a known issue with the dell idrac and 13.10? i have used it with all previous versions to date. It is a dell r720
to your kernel commandline parameters from the Grub menu and it should work. Something to do with the power management putting the iDrac fake keyboard to sleep.
