Maybe I missed it but all I found was how to rotate the display 180 degrees. I’m planning on upgrading to a larger display, probably the 21" ASUS. But I really don’t need it that big so I was thinking it might be nice to switch from landscape to portrait mode so you don’t have to scroll up and down as often. I assume it can be done, has anyone tried?
Check out this thread for instructions on rotating the screen – make sure you read down to the part about updating the touch input matrix as well as the display output.
Edit: Regarding your comment on 180-degrees – you can rotate any multiple of 90 depending on your value of
display_rotate. Read that thread in detail and you should find what you need.
