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+<— 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

For 180° rotation (landscape):

 xrandr -o 2 && xsetwacom set "Mouse[7]" Rotate 3

For 270° rotation (counterclockwise, portrait):

 xrandr -o 1 && xsetwacom set "Mouse[7]" Rotate 2

Note that the commands above depend on the contents of your /etc/X11/xorg.conf configuration file. If the example configuration presented in Example E.1, “Configuration for Wacom Devices” has been used, the commands should work as they are written. If you have changed the Identifier of the tablet stylus input device in xorg.conf, replace "Mouse[7]" with the new Identifier.
