[Bug 1216228] Re: xrandr reports slightly different (less accurate) output dimensions under XMir

[Daniel van Vugt]

It seems both answers are correct, depending on where you look:

$ edid-decode /sys/class/drm/card0-HDMI-A-1/edid
...
Maximum image size: 52 cm x 33 cm
...
Detailed mode: Clock 154.000 MHz, 519 mm x 324 mm

Though I suggest we should be using the latter.

Title:
  xrandr reports slightly different (less accurate) output dimensions
  under XMir

Status in Mir:

Bug description:
  XMIR-0 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 280mm x 160mm
  vs
  LVDS1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 277mm x 156mm

  The latter (native X) is more accurate. Is XMir/Mir rounding to
  centimetres?
