Christopher, thanks for the hint. Dell ships a mini-DisplayPort to DisplayPort cable (DP-mDP) with the display. The mDP cable is connected to the X250 and the DP cable is connected to the display. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1547043 Title: 4k Support not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547043/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1547043] Re: 4k Support not working
Hi Christopher, I have checked this. But by now only with the 27" Dell. (The resolutions are anyway the same.) Ubuntu offers resolutions up to 3840 x 2160 px. The largest working resolution is 1920 x 1200 px. Both higher resolutions (3840 x 2160 px and 2560 x 1440 px) result in a black external display. As I am using a freshly installed live stick with Ubuntu 15.10 i don’t expect any *.old log files to appear. I have only attached the Xorg.0.log file after testing your scenario. ** Attachment added: "Xorg.0.log" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547043/+attachment/4577053/+files/Xorg.0.log -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1547043 Title: 4k Support not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547043/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

MIME, to advise, if you are going to test live environments, please test the latest one found at http://cdimage.ubuntu.com/daily-live/current/ . This keeps the results as helpful as possible. Despite this, to clarify, you are using a mini-DisplayPort cable plugged into your laptop, and plugging it into the mini-DisplayPort port of the P2415Q? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1547043 Title: 4k Support not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547043/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
