Using the proprietary NVIDIA driver (384.59), I can't rotate a screen. It works with the Intel drivers for the integrated graphics instead the Optimus/Prime. The control panel only offers the rotation "normal" and xrandr fails like this:

xrandr --output VGA-1-1 --rotate left
xrandr: output VGA-1-1 cannot use rotation "left" reflection "none"

There are similar unanswered questions here: Rotate dual monitor screen 90 degrees on Ubuntu 15.10 and How can I rotate my notebook screen 90 degrees although 'xrandr --rotate' does not support it?

xorg.conf has the "Device" section with Option "RandRRotation" "true" added as suggested here, but no avail.

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1@0:0:0"
    Option "ConstrainCursor" "off"
    Option "RandRRotation" "true"
EndSection

Now the question: It is claimed by a Nvidia dev that Canonical patched X so that one can't rotate the screen using the proprietary driver. The linked issues are fixed by now though. Is this true and why? Can I install an unpatched X or one that has this patch removed?
