[Ubuntu-x-swat] [Bug 1955138] [NEW] External monitor stops showing image for a few seconds
Public bug reported: I use Dell Dock Station - D6000S and noticed in the latest two kernels an instability on my external monitors. I use two external monitors and they randomly stops showing the images for a couple of seconds. It's similar as if the usb-C connection to the docker got interrupted and then connected again. Notebook display doesn't have this issue. Please verify the root cause.
