I forgot to mention - HDMI can also cause bugs such as this. We've seen reports where some people can't get HDMI monitors to sleep, but other connection types do. In some cases the problem was traced to the HDMI audio feature.

Actual behavior: * External displays connected through a DisplayLink dock are forced to the same scaling ratio * Closing the laptop lid when external displays are connected through a display link dock results in the internal display turning off but no sleep behavior * This happens regardless of config changes with dconf, upower, or logind This is primarily a usability issue for laptops with limited ports for IO and extremely high resolution internal panels.
