I'm desperately looking for a way to get two separate (i.e. "Extended" or splitted) display output on my Android x86 setup.

It appears that I need to modify the content of /grub/menu.lst file, but every guide that I can find online instructs the user to either clone (i.e. "duplicate" or mirroring) the displays, or worse, it instructs the user to entirely disable the internal LVDS display. This is not what I want.

What I want is to simply have a separate output for each of my displays (two 1920x1080 monitors using HDMI.) This is something that is available on many Linux distros and even Windows.

Is what I want even possible on Android x86?

A quick check of android-x86.org shows at the bottom:

Development (2019/10)

What we are working on now

  • Android 10 (Q release) porting (q-x86 branch)
  • Upgrade kernel to 4.19 or newer
  • OpenGL ES hardware acceleration for intel/radeon/nvidia/amdgpu (pstglia, mauro) and virgl(robh) GPUs.
  • HDMI audio (cwhuang)
  • LineageOS integration (jjm)
  • Hardware accelerated codecs

To-Do List

  • Multiple displays support
  • Better power management
  • Miracast

So the feature Multiple display support is on the To-Do List and probably dependent on OpenGL ES hardware acceleration efforts.

So as of 2019-10 the feature you want isn't available.

This feature is not yet available. You could instead switch between your screens by adding video=LVDS-1:d to your grub configuration file.
