I've got an external monitor plugged in via DisplayPort that always used to come online in Ubuntu 15.04 after I resumed the laptop from suspend. In 15.10 however, the monitor will often just stay black and it takes me re-plugging the cable to bring the picture back on it.

Vadim Peretokin, thank you for reporting this and helping make Ubuntu better.
As per http://
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
For more on BIOS updates and linux, please see https:/
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.
Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status New. Otherwise, please mark this as Invalid.
Thank you for your understanding.
