[Kernel-packages] [Bug 1520751] Re: Kernel 4.2 does not detect external monitor
You mean upgrade to the whole distribution or just the kernel? This issue is happening on my main work laptop so I need reasonable stability so I'm not sure I want to use a pre-alpha distro. I think for now I am fine using the mainline 4.3 kernel which works fine, or the 4.2.0-rc8 one which I compiled corresponding to the first good commit. (The 4.3 one is also giving me a few bugs which I think are unrelated). So I think I can wait for the backport. Thanks again for your help.

Christopher, I have finished the bisection (man, that took a long time!) and I have attached the output. The summary is that commit 4efa83c8c786ab7ec7982e3dd348cb7e7ecbeb04 is the one that fixes things.

[Kernel-packages] [Bug 1520751] Re: Kernel 4.2 does not detect external monitor
David Abergel, the next step is to fully reverse commit bisect from kernel 4.2 to 4.3 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

[Kernel-packages] [Bug 1520751] Re: Kernel 4.2 does not detect external monitor
Dear Christopher, I updated the BIOS today. Ouput from the command you requested is: $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date [password] A07 11/11/2015 The problem persists, so I have marked this as Confirmed, per your request. As I stated in the initial post, the problem is that when I connect an external monitor, it is not detected using the standard 4.2.x.xx kernel. When I use the mainline 4.3 kernel, the external monitor is detected and operates as expected. If you need any other specific information, please don't hesitate to ask. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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/1520751 Title: Kernel 4.2 does not detect external monitor Status in linux package in Ubuntu: Confirmed Bug description: On xubuntu 15.10.

[Kernel-packages] [Bug 1520751] Re: Kernel 4.2 does not detect external monitor
Dear Christopher, Thank you for the suggestion. Unfortunately, I won't be able to do this for at least a week because Real Life™ is too busy. (Also, I've not updated a BIOS before so I am cautious about the idea.) But if I can do it some time in the next week or two I shall update the bug. Cheers.

[Kernel-packages] [Bug 1520751] Re: Kernel 4.2 does not detect external monitor
David Abergel, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/19/product- support/product/xps-13-9343-laptop/drivers/advanced an update to your computer's buggy and outdated BIOS is available (A07). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it address the issue? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-a07 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1520751 Title: Kernel 4.2 does not detect external monitor Status in linux package in Ubuntu: Incomplete Bug description: On xubuntu 15.10.
