Hi,

I am using A20 Lime2-4gb, with official debain8 jessie image and 40 pin LCD touch screen (NHD-7.0-800480EF-ASXN#-CTP) connected to it.I have tried xrand command too but it gives no change.How can I rotate the screen?

Thanks,
AnkyB

I changed usr/share/X11/xorg.conf/99-something.conf and added

option "rotate" "cw"

But this, unfortunately, will not rotate the mouse cursor.

Have you added it to the device section?
It's an option of the fbturbo driver.
This does only take effect after a restart of X.
fbturbo has no support for the rotation xrandr uses.

For me this fucks up the mouse cursor, which does not get rotated and clicks do not get registered where the cursor got displayed
