E.4 Troubleshooting
Virtual Keyboard Does Not Appear on Login Screen
Occasionally, the virtual keyboard is not displayed on the login screen. To solve this, restart the
X server by pressing Ctrl+Alt+Backspace or press the appropriate key on your Tablet PC (if
you use a slate model without integrated keyboard). If the virtual keyboard still does not show,
connect an external keyboard to your slate model and log in using the hardware keyboard.
Orientation of the Graphics Tablets Does Not Change in GNOME
With the xrandr command, you can change the orientation of your display from within a
shell. Enter xrandr --help to view the options available. To simultaneously change the
orientation of your graphics tablet, the command needs to be modified as described below:
For normal orientation (0° rotation):
xrandr -o 0 && xsetwacom set "Mouse[7]" Rotate 0
For 90° rotation (clockwise, portrait):
xrandr -o 3 && xsetwacom set "Mouse[7]" Rotate 1
