dmesg of DP dongle plugged in after X starting
Environment:
-------------------
Kernel: (drm-intel-next-queued) f1fcde49872f390a4060fa9ee8b02d3f2a8508b7
Hardware name: Apple Inc. MacBookPro10,2/Mac-AFD8A9D944EA4843,
BIOS MBP102.88Z.0106.B03.1211161133 11/16/2012
Description:
--------------------
When I plugged the miniDP-to-DP dongle in the machine after booting up and
starting X, the DP monitor was black, while xrandr command showed "DP2
connected (normal left inverted right x axis y axis)".
After I set command "xrandr --output DP2 --preferred" , the monitor can show
correctly. And the hotplug will also work well since then.
The miniDP-to-DP dongle hotplug works well without starting X.
Test Step:
--------------------
1.reboot machine
2.start X
3.plug in miniDP-to-DP</pre>
