Dell D6000 dock resetting on Ubuntu 16.04
Hi,
Every 1-2 hours (in random intervals, sometimes shorter) my two monitors stop getting a signal. If I unplug the dock they start working again. The keyboard and mouse still work though. Hardware: Latitude 7280, D6000 dock, Dell monitors Software: Ubuntu 16.04 (i3 window manager) Initially the monitors didn't work at all, but started after I installed different graphics drivers (these ones) dmesg outputs these messages: Quote:

Hi Szymon,
Fedora 26, same displaylink device, exhibits same behaviour. Log attached. |

Update: DisplayLinkManager crashes that are inside the report are not related to this case (but would be worth investigating nevertheless). |

Dell XPS 15 9560 + Dell D6000 @ Ubuntu 17.10 Beta 2 (Gnome @ Xorg)
Random dock disconnect (everything). Re-connecting fixes the issue. Attaching log after 2 disconnects. EDIT: My bad, only display goes black. |

Same issue here. Dell D6000 Dock, 130W adapter, and Latitude 7480

I found a way to bring a display back to life if it's off but available from xrandr output. You need to say something like
Code:
xrandr --output DVI-I-2-2 --auto Code:
xrandr --output DVI-I-2-2 --right-of eDP1 |
If you use arandr, you can save the monitor config. It saves as a .sh so you just get to re-execute that script and it will re-arrange your monitors.
Handy for having multiple configurations that you use and scripting between them with udev. |

My earlier advise about using xrandr is not working for me either :( I now have monitors shown as on in xrandr, but they are in fact in power saving mode. All this happens once in a while, when a message appears in kernel logs:
Code:
[18125.523348] usb 4-1.1: Disable of device-initiated U1 failed. |
