I have been working out of the office for some weeks now without access to the dock.
Been back for a while now and some update since then have fixed the issue. Have been daily for a few days now connecting and disconnecting from dock and it has worked without any flaws. I can no longer reproduce the bug. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1575038 Title: Connecting docking station reboots computer Status in linux package in Ubuntu: Incomplete Bug description: When connecting a awake and running laptop to Dells docking station the desktop crashes and shows the disk encryption password login prompt: https://goo.gl/photos/9QEkQDkNPbT71wDD6 After entering the password all screens goes black and nothing happens.
