I have a similar issue with my Dell Latitude 7250. I have Ubuntu Gnome
16.04, 64 bit installed on the laptop and connected to a dock. I have 3
Dell 22" monitors connected. One of the monitor is using a VGA
connector, and two are using DVI connectors on the monitor.
The issue is - when I start my day the set up works nicely. But when the
screens go in the sleep mode and the laptop also goes in suspend,
getting the screens working properly is a pain. One of the screens keep
flickering. The fix that I have to apply is go to display settings,
disable the monitor that is flickering and then re-enable the monitor.
The monitor then stops flickering and works well. But then I have to re-
arrange the monitor display.
Attaching dmesg and lspci-vvnn outputs.
Regards
Kedar
