This issue initially happened on both intel and nvidia gpus after 16.04
was released but the bug was fixed for intel gpus at some point but
remains for nvidia.

Title:
Hotplugging HDMI fails
Status in nvidia-graphics-drivers-352 package in Ubuntu:
Confirmed
Bug description:
Affected computer: Dell Precision 15 5000 Series (5510) with Quadro
M1000M/PCIe/SSE2 graphics card (kernel 4.2.0-23-generic).
Expected behaviour:
- hotplugging HDMI cable would work
Current behaviour:
- Hotpluging doesn't work (no kernel events, used udevadm monitor to
verify)
Current observations:
- HDMI output works if connected from the boot
- When DPMS kicks in HDMI output disappears (tested with 2 different monitors)
- Hotpluging doesn't work (no kernel events, used udevadm monitor to verify)
- VGA (via usb-c adapter) works, hotplugging also
- HDMI (via usb-c adapter) causes black screen in computer display and
eventually crashes X. Unplugging adapter before crash restores state (computer
display restored)
- display port (via usb-c adapter) hotplugging works
I can provide more information if required.
How could I debug this nvidia driver even more? I really would like to
solve this issue.
