This device has three display connectors, 1x DisplayPort, 2xHDMI. I'm having a Display with 2560x1600, and thus want to use with with DisplayPort for full resolution. When connecting screen and PC with DisplayPort, both the BIOS and the Linux BootSplash/Console correctly recognize the screen to be connected to DisplayPort and are displayed as usual. But as soon as X starts, screen becomes black (and the screen itself somewhat confused, because it does not even respond to the menu button anymore). Interestingly, the same screen worked properly when connected with DisplayPort to another Linux machine with 14.04. Connecting the screen with HDMI instead works without any problems, but gives a reduced resolution of 1920x1080 only. regards ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: xserver-xorg 1:7.7+7ubuntu4 ProcVersionSignature: Ubuntu 4.2.0-14.16-generic 4.2.2 Uname: Linux 4.2.0-14-generic x86_64 ApportVersion: 2.19-0ubuntu1 Architecture: amd64 CurrentDesktop: XFCE Date: Wed Oct 7 10:01:31 2015 InstallationDate: Installed on 2015-09-03 (33 days ago) InstallationMedia: Xubuntu 15.10 "Wily Werewolf" - Alpha amd64 (20150825) SourcePackage: xorg UpgradeStatus: No upgrade log present (probably fresh install) --- ApportVersion: 2.19.1-0ubuntu2 Architecture: amd64 CurrentDesktop: XFCE DistroRelease: Ubuntu 15.10 InstallationDate: Installed on 2015-09-03 (45 days ago) InstallationMedia: Xubuntu 15.10 "Wily Werewolf" - Alpha amd64 (20150825) Package: xorg 1:7.7+7ubuntu4 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.2.0-16.19-generic 4.2.3 Tags: wily Uname: Linux 4.2.0-16-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip libvirtd lpadmin plugdev sambashare scanner sudo video www-data _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1503590/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
