Version-Release number of selected component (if applicable): Fedora 23 x64 Kernel: 4.4.0-0.rc4.git3.2.fc24.x86_64 #1 SMP Thu Dec 10 20:13:41 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux How reproducible: Always Steps to Reproduce: 1.

Additional info: System shutdown or suspend works properly if an external monitor is not attached. Attached journalctl -k -b -1 with trace.
I own the similar Dell XPS 15 9550 and can confirm this issue. Moreover it is not restricted to external monitors but actually happend with everything plugged into the USB Type C port. I tested to connect the following devices: - Nexus 5x - USB 3.1 Type C Ethernet Adapter - Type C to VGA Adapter (without connected monitor) - USB 3.1 Type C to USB 3.0 Type A female Adapter (without connected device) Especially the Type C->A Adapter is a totally dumb device. This leads me to conclusion that this is a general problem with the Type C port and not related to the connected device. I don't know if this is the same issue as Steve has, it would be nice if you (Steve) can verify if other (non-graphics) USB Type C devices work for you.
Unfortunately I don't own any other USB-C devices to test with. But I can confirm that there is no requirement for the external monitor to be connected to the adapter for this issue to occur.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
