description |
When using an external 4K monitor plugging into the mini display port on my Dell XPS 13 9343 using both the laptop screen and the external monitor (external monitor is left and laptop screen right), when using all of the following kernels:
4.4.0-2.16-generic
4.4.0-4.19-generic
4.4.0-6.21-generic
4.4.0-7.22-generic
the external monitor will sometimes blink off for about a second or two, then back on. What is weird is this seems to only happen when typing into a gnome-terminal as opposed to firefox or evolution. Simply changing to a gnome-terminal and typing into it doesn't cause the blinking, but it might happen immediately or it might take several minutes.
4.3.0-7.18-generic worked fine and I can go hours and hours in a gnome-terminal with no issues.
