[Kernel-packages] [Bug 1589397] Re: kernel panic connecting display port to Dell Latitude E7470
Looks like it is not working today with any of the above kernels - I had multiple screens working ok on Friday with the mainline kernel, but today it is not working. I'm not sure what changed, I will attach the dpkg log, but am going to have to go to windows as this is a work laptop and i can't spend more time looking at this. Hopefully I can help debug in future if I get time to repartition again or perhaps with a beta live-usb image -- 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/1589397 Title: kernel panic connecting display port to Dell Latitude E7470 Status in linux package in Ubuntu: Confirmed Bug description: Connecting an external Display Port screen wither via the dell E-Port plus or directly via the miniDP causes a kernel panic.
