I'm running Ubuntu 15.04 (Ubuntu gnome). When I start the computer, it shows the gnome logo and asks to enter my encrypted password to unlock the disk. However, I cannot enter the password.
Nothing happens if I type the password or hit Enter. Not really sure what to do. The only way I can log in is if I use a PS/2 keyboard, but I don’t want this to be permanent, I would like to go back to my wireless USB keyboard.
