If the external monitor is attached after X has started I can boot to the desktop using only using the laptop's LCD (ThinkPad x230, intel graphics). The attaching a 1920x1080 LCD via miniDP extends the desktop but windows moved around produce a trail of windows that persist even after the window is closed. This is a regression from Xenial. $ lsb_release -rd Description: Ubuntu Yakkety Yak (development branch) Release: 16.10 $ apt-cache policy xorg xorg: Installed: 1:7.7+13ubuntu4 Candidate: 1:7.7+13ubuntu4 Version table: *** 1:7.7+13ubuntu4 500 500 http://archive.ubuntu.com/ubuntu yakkety/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 16.10 Package: xorg 1:7.7+13ubuntu4 ProcVersionSignature: Ubuntu 4.8.0-19.21-generic 4.8.0-rc8 Uname: Linux 4.8.0-19-generic x86_64 .tmp.unity_support_test.0: ApportVersion: 2.20.3-0ubuntu7 Architecture: amd64 CasperVersion: 1.379 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Fri Oct 7 20:23:46 2016 DistUpgraded: Fresh install DistroCodename: yakkety DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo 3rd Gen Core processor Graphics Controller [17aa:21fa] LiveMediaBuild: Ubuntu 16.10 "Yakkety Yak" - Alpha amd64 (20161007) MachineType: LENOVO 2306CTO ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/casper/vmlinuz.efi file=/cdrom/preseed/username.seed boot=casper quiet splash --- SourcePackage: xorg UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/25/2013 dmi.bios.vendor: LENOVO dmi.bios.version: G2ET97WW (2.57 ) dmi.board.asset.tag: Not Available dmi.board.name: 2306CTO dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrG2ET97WW(2.57):bd10/25/2013:svnLENOVO:pn2306CTO:pvrThinkPadX230:rvnLENOVO:rn2306CTO:rvrNotDefined:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 2306CTO dmi.product.version: ThinkPad X230 dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.13.0+16.10.20160818.2-0ubuntu2 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.70-1 version.libgl1-mesa-dri: libgl1-mesa-dri 12.0.3-1ubuntu1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 12.0.3-1ubuntu1 version.xserver-xorg-core: xserver-xorg-core 2:1.18.4-1ubuntu6 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.2-1ubuntu1 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.7.1-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20160706-1ubuntu1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.12-2 xserver.bootTime: Fri Oct 7 20:18:12 2016 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.version: 2:1.18.4-1ubuntu6 xserver.video_driver: modeset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1631519/+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
