EXT: [PATCH weston 0/1] Allow forcing outputs on

[Tomasz Olszak]

To reproduce the issue:

weston.ini:
[output]
name=HDMI-A-2
mode=74.50  1280 1344 1472 1664  720 723 728 748 -hsync +vsync
force-on=true

Connect screen to HDMI-A-1 and start weston. You get weston info:
interface: 'wl_output', version: 3, name: 13
       x: 0, y: 0, scale: 1,
       physical_width: 410 mm, physical_height: 230 mm,
       make: 'PHL', model: 'Philips 196V',
       subpixel_orientation: unknown, output_transform: normal,
       mode:
...
interface: 'wl_output', version: 3, name: 14
       x: 1366, y: 0, scale: 1,
       physical_width: 0 mm, physical_height: 0 mm,
       make: 'unknown', model: 'unknown',
       subpixel_orientation: unknown, output_transform: normal,
       mode:
               width: 1280 px, height: 720 px, refresh: 59.855 Hz,
               flags: current


Now disconnect HDMI-A-1:
interface: 'wl_output', version: 3, name: 14
       x: 2732, y: 0, scale: 1,
       physical_width: 0 mm, physical_height: 0 mm,
       make: 'unknown', model: 'unknown',
       subpixel_orientation: unknown, output_transform: normal,
       mode:
               width: 1280 px, height: 720 px, refresh: 59.855 Hz,
               flags: current

That seems like a bug.
