How to get rotated video in text mode (no X), even during booting sequence ?

OS: Linux

Graphics card: mostly ATI, but curious about NVida and Intel solutions.

  • What's your OS? Bootloader? Graphics chip might matter too. – Mat Aug 8 '12 at 9:38

See the fbcon documentation. Basically:

echo 0 | sudo tee /sys/class/graphics/fbcon/rotate  # normal
echo 1 | sudo tee /sys/class/graphics/fbcon/rotate  # clockwise
echo 3 | sudo tee /sys/class/graphics/fbcon/rotate  # counterclockwise

You can add the kernel parameter fbcon=rotate:1 to achieve the same thing at boot.
