Virtual screen

Trying to figure out how to use an ipad as a 2nd display in ubuntu, without much success at this point.

See this about xrandr and this about x11vnc.

• iPad mini 4 is 2048 × 1536 (half that is 1024 × 768).

• iPad Pro is 2732 × 2048 (half that is 1366 × 1024).

• install x11vnc

  sudo apt update
  sudo apt install x11vnc
  

• create /usr/share/X11/xorg.conf.d/20-intel.conf containing the following:

  Section "Device"
      Identifier "intelgpu0"
      Driver "intel"
      Option "VirtualHeads" "2"
  EndSection
  

• Log out and log in again, and when you type xrandr there'll be VIRTUAL1 and VIRTUAL2 listed
