Second Display stopped working.

Hi all.

So I have been using my PC all day on and off. I just woke my PC from
sleep half an hour ago and the second display wouldn't come on. It does
not show up in Settings > display Settings any more.

The gpu is a Nvidia GTX 760 graphics card with 2x Dell 24 inch monitors.
The first is connected by HDMI, the second by Display port.

I rebooted. Still not working

I ran sudo apt upgrade then rebooted. Nope.

I went into additional drivers and removed then re-installed the Nvidia
driver. Nope.

Still not working.

If I go into Nvidia settings the monitor on displayport shows up but
will not let me enable it.

If I reboot to windows 7 everything works as before so it mustn't be a
hardware problem.

What on earth has happened?

I was using both monitors. Put PC to sleep. Wokle it up and bam! I am
stuck with this!.

What can I check to diagnose this?

The magic incantation is:

sudo apt update
sudo apt full-upgrade

Also, check your laptop's firmware is current, and if not, update it.

What happens if you unplug the second screen, wait ten seconds then
plug it back in again. If it still doesn't work then unplug it, run
in a terminal
tail -f /var/log/syslog
and post what you see there when you plug it back in. If you hit
enter a few times after starting the tail then you will get some blank
lines on the screen which makes it easier to see where you started.

Also tell us which version of Ubuntu you are using.

However, I ran the command you asked anyway. Then unplugged the second
display. Then I connected it back up again.

If it goes wrong again I will repeat this.

I have had ubuntu on this computer since 15.10 and always upgraded it
and kept it up to date. This is the first problem I have had on it.

I have it set up as triple boot with Ubuntu openSUSE and Windows 7.
OpenSUSE and windows 7 work fine still.

Same issue here.
I use my laptop screen as the primary display. Sometimes the second display
works, sometimes it doesn't.
