Write 1 to <tt>/sys/class/graphics/fbcon/rotate</tt>. To do it from the kernel, add <tt>fbcon=rotate:1</tt> to the kernel command line; in Raspbian, this is done by editing <tt>/boot/cmdline.txt</tt>. This has no effect on Xorg. | Write 1 to <tt>/sys/class/graphics/fbcon/rotate</tt>.

==Touch rotation== | |||
We can do it through Xorg: add the appropriate <tt>CalibrationMatrix</tt> to the <tt>touchscreen</tt> libevent stanza. For instance, rotate 90 degrees clockwise with <tt>Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"</tt>. But this will only work for X. | |||
If we want to handle all libinput consumers (particularly [[Wayland]]), it's better to make a [[udev]] rule that sets <tt> | |||
ENV{LIBINPUT_CALIBRATION_MATRIX}="0 1 0 -1 0 1</tt>. You can test this by checking <tt>libinput list-devices | grep ^Calibration:</tt>. | |||
