** Description changed: - Hi, - I've installed 15.10 beta on a brand new ASRock beebox N3150 PC. 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 ** Attachment removed: "Dependencies.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1503590/+attachment/4486969/+files/Dependencies.txt ** Attachment removed: "JournalErrors.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1503590/+attachment/4486970/+files/JournalErrors.txt ** Attachment removed: "ProcEnviron.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1503590/+attachment/4486971/+files/ProcEnviron.txt ** Attachment removed: "JournalErrors.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1503590/+attachment/4499981/+files/JournalErrors.txt ** Attachment removed: "Dependencies.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1503590/+attachment/4499980/+files/Dependencies.txt ** Attachment removed: "ProcEnviron.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1503590/+attachment/4499982/+files/ProcEnviron.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1503590 Title: Trouble with DisplayPort Status in xorg package in Ubuntu: Incomplete Bug description: I've installed 15.10 beta on a brand new ASRock beebox N3150 PC.
