Public bug reported:
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
- display port (via usb-c adapter) not confirmed (going to when I got the
adapter)
I think this is rooted to issue that hotplugging HDMI cable doesn't work
properly. I can provide more information if required.
How could I debug this nvidia driver even more? I really would like to
solve this issue.
I have Dell Precision 15 5000 Series (5510) with Quadro M1000M/PCIe/SSE2
graphics card (kernel 4.2.0-23-generic).
