John Ioannidis, just to clarify, is it that when you plug the second+ monitor in, then the mouse, keyboard, etc. becomes unresponsive? Is it that xorg crashes (ex. you are logged out automatically)?

Connected to three Dell U2415 monitors, daisy-chained using the DP output. As you can see from Xorg.0.log, all three monitors are detected, and the framebuffer is set to 5760 x 1200 (3 * 1920 x 1200). This problem only manifests itself when connected to more than one monitor. --- ApportVersion: 2.17.2-0ubuntu1 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None DistUpgraded: Fresh install DistroCodename: vivid DistroRelease: Ubuntu 15.04 DistroVariant: ubuntu DkmsStatus: virtualbox, 4.3.26, 3.19.0-16-generic, x86_64: installed GraphicsCard: Intel Corporation Broadwell-U Integrated Graphics [8086:1626] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation Device [8086:2057] InstallationDate: Installed on 2015-05-09 (2 days ago) InstallationMedia: Kubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) Package: xorg 1:7.7+7ubuntu4 PackageArchitecture: amd64 ProcEnviron: LANGUAGE= TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.19.0-16-generic.efi.signed root=/dev/mapper/kubuntu--vg-root ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.19.0-16.16-generic 3.19.3 Tags: vivid ubuntu UdevLog: Error: [Errno 2] No such file or directory: '/var/log/udev' Uname: Linux 3.19.0-16-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: _MarkForUpload: True dmi.bios.date: 04/15/2015 dmi.bios.vendor: Intel Corporation dmi.bios.version: RYBDWi35.86A.0247.2015.0415.1351 dmi.board.name: NUC5i5RYB dmi.board.vendor: Intel Corporation dmi.board.version: H40999-502 dmi.chassis.type: 3 dmi.modalias: dmi:bvnIntelCorporation:bvrRYBDWi35.86A.0247.2015.0415.1351:bd04/15/2015:svn:pn:pvr:rvnIntelCorporation:rnNUC5i5RYB:rvrH40999-502:cvn:ct3:cvr: version.compiz: compiz N/A version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.60-2 version.libgl1-mesa-dri: libgl1-mesa-dri 10.5.2-0ubuntu1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.5.2-0ubuntu1 version.xserver-xorg-core: xserver-xorg-core 2:1.17.1-0ubuntu3 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.9.0-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.5.0-1ubuntu2 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917-1~exp1ubuntu2.1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.11-1ubuntu2build1 xserver.bootTime: Mon May 11 19:54:13 2015 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: xserver.version: 2:1.17.1-0ubuntu3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1453306/+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
