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.
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 --output LVDS ---rotate normal && xsetwacom set "Mouse[7]" Rotate NONE
For 90° rotation (clockwise, portrait):
xrandr --output LVDS ---rotate right && xsetwacom set "Mouse[7]" Rotate CW
For 180° rotation (landscape):
xrandr --output LVDS --rotate inverted && xsetwacom set "Mouse[7]" Rotate HALF
For 270° rotation (counterclockwise, portrait):
xrandr --output LVDS --rotate left && xsetwacom set "Mouse[7]" Rotate CCW
Note that the commands above depend on the contents of your
/etc/X11/xorg.conf configuration file. If you
have configured your device with SaX2 as described in
Section 33.2, “Configuring Your Tablet Device”, the commands should work as they
are written. If you have changed the
Identifier of the tablet stylus input device
in xorg.conf manually, replace
"Mouse[7]" with the new
Identifier. If you have a Wacom device with
Touch support (you can use your fingers on the tablet to move the
cursor), you need to rotate also the touch device.
