4.8 Rotation Mode Configuration
An option for screen rotation is available for the Raptor 4000R
board. Only the first head, the one closest to the PCI bus, will
support video for the rotator board.
To set the card in rotation mode, the
"Rotation"
option
must
be uncommented in the
“Device” Section
in the
xorg.conf
file. This option must be set prior to starting the Xserver. If this
option is commented out, then X Windows will be displayed in
regular, non rotated mode.
There are two rotation modes, clockwise and counterclockwise.
To start X Windows in clockwise rotated mode, set the
"Rotation"
option to
“+r”
prior to starting the X server.
