Hi, I wasn't reachable for a week, but I'm back now.
So. There is a way to set the keyboard layout from console. Open konsole, and type the following:
This will open the xorg config file. Here search for an entry like this:
Option "XkbModel" "pc105"
Option "XkbLayout" "en"
Option "XkbOptions" ""
As you can see there is a XkbLayout entry. You need to set this. I think you will find dvorak "instead" of "en" here, so the only thing you need to do, is to set it back to "en" or something else you need. After you set the option, save the config file, exit konsole and reboot X server (with key combination Ctrl+Alt+Backspace). After login window comes you'll have an english keyboard layout.
