I postponed accepting this into x-proposed. There are major changes here which really should get some field testing in yakkety first.

[Test Case] 1) Boot Ubuntu and run the following command, looking for gpu-manager: systemd-analize blame This will show how long gpu-manager took. Write down the number 2) Install the package from -proposed, and run systemd-analize blame. See if the number has become smaller. [Regression Potential] Low, all the changes are already included in Yakkety. _____________________ Rather than calling drm directly, gpu-manager should simply check the outputs connector status by using the sysfs filesystem (e.g. /sys/class/drm/card0-HDMI-A-1/status, etc.), thus relying on data that is already available. This should make gpu-manager a bit less resource intensive, especially on boot. The attached perf shows the problem in gpu-manager.
