[Bug 754799] Re: [arrandale] external VGA output doesn't output anything
Hi Bryce,
The hotkey itself is functional, as in, if I press it, the integrated
display does some flickering thing (like other systems do just before
sending the display to external), but external still shows nothing.
xrandr --auto doesn't do anything.
xrandr -q shows this with the external display connected:
Screen 0: minimum 320 x 200, current 2646 x 1024, maximum 8192 x 8192
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1366x768 60.2*+
1360x768 59.8 60.0
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 connected 1280x1024+1366+0 (normal left inverted right x axis y axis) 376mm x 301mm
1280x1024 60.0*+ 76.0 75.0 72.0
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3
640x480 72.8 75.0 66.7 60.0
720x400 70.1
640x350 70.1
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
So it's very weird because the system *is* detecting the display but nothing gets sent to it somehow.
