Comment 87 for bug 1295267

Comment #86 should be deleted because the Windows fluff is detracting from serious Linux conversation.

I often close the Intel HD530 driven laptop lid and windows there move to nVidia GTX 970M HDMI hardwired external TV. The windows on the Thunderbolt Intel HD 530 driven external monitor TV stay consistent.

If I do not turn on the TV's before resuming from suspend, then the windows on the Thunderbolt driven TV (right side) disappear off screen and I have to use <Alt>+<Tab> to select the disappeared window. Then I need to hold <Alt>+<F7>+<Left Click> and move mouse left to force window back onto canvass.

Another annoying non-Ubuntu-fault-probably-Xorg-fault problem is that when opening and closing laptop lid both external TVs reset. The Intel HD 530 Thunderbolt connected via DP to HDMI converter plug resets it's XRANDR setting for --gamma 1:.9:.7 --brightness .5 so I have to recall it from bash history and resend the command.

When one monitor deactivates, cannot the windows simply move to the other screens (as they do now) without reseting the other monitors/TVs?

In /var/log/Xorg.log nVidia sends out messages but Intel HD 530 (i915 driver) doesn't appear to send out messages.

Unfortunately googling how to override these issues via XORG hooks or even a custom script that monitors UDEV events sheds no light on the situation.

Overall things have improved greatly over the last three years (18.04 problems excluded) so I don't want to sound negative. Laptop eDP Windows do move properly to main HDMI TV on lid close and back to laptop eDP on lid open.
