Thank you for your bug report, what's the output of the command? - dpkg -l | grep dock
the bug is similar to bug #1719706 but that was fixed, do you use the ubuntu dock or did you install dash to dock? ** Package changed: xorg (Ubuntu) => gnome-shell-extension-ubuntu-dock (Ubuntu) ** Changed in: gnome-shell-extension-ubuntu-dock (Ubuntu) Importance: Undecided => Low ** Changed in: gnome-shell-extension-ubuntu-dock (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell-extension-ubuntu-dock in Ubuntu. https://bugs.launchpad.net/bugs/1814387 Title: swithching workspace by scrolling on edge of Dock (left side bar) Status in gnome-shell-extension-ubuntu-dock package in Ubuntu: Incomplete Bug description: If you position the mouse corsor on the edge of Dock and scroll, you can switch the workspace, which behaves equivalent to the scrolling on the "Show Applications" button in the corner. I've reproduced it on other Ubuntu 18 installations of friends (all 3 I tested, at least one was a fresh installation from the official iso). It is not important where Dock is or whether a window or the desktop is next to it. Program shortcuts have also no effect, because they end before it. It works with a single or 2 monitors on all instances of Dock. I use Ubuntu 18.04.1 LTS with all updates (via apt upgrade) installed and observed it for several months now. (After starting apport for this I updated again and nothing changed, no restart) ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg 1:7.7+19ubuntu7.1 ProcVersionSignature: Ubuntu 4.15.0-43.46-generic 4.15.18 Uname: Linux 4.15.0-43-generic x86_64 .tmp.unity_support_test.0: ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Sat Feb 2 16:10:48 2019 DistUpgraded: 2018-10-01 14:59:21,229 DEBUG Running PostInstallScript: './xorg_fix_proprietary.py' DistroCodename: bionic DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) Subsystem: CLEVO/KAPOK Computer 4th Gen Core Processor Integrated Graphics Controller [1558:2300] Subsystem: CLEVO/KAPOK Computer GM107M [GeForce GTX 860M] [1558:2300] InstallationDate: Installed on 2017-03-18 (685 days ago) InstallationMedia: Ubuntu 16.04.2 LTS "Xenial Xerus" - Release amd64 (20170215.2) MachineType: Notebook W230SS ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.15.0-43-generic root=UUID=907d4e48-c148-454e-aa8a-7adb74d51fb2 ro quiet splash vt.handoff=1 SourcePackage: xorg Symptom: display UpgradeStatus: Upgraded to bionic on 2018-10-01 (124 days ago) dmi.bios.date: 04/15/2014 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 4.6.5 dmi.board.asset.tag: Tag 12345 dmi.board.name: W230SS dmi.board.vendor: Notebook dmi.board.version: Not Applicable dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: Notebook dmi.chassis.version: N/A dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr4.6.5:bd04/15/2014:svnNotebook:pnW230SS:pvrNotApplicable:rvnNotebook:rnW230SS:rvrNotApplicable:cvnNotebook:ct9:cvrN/A: dmi.product.family: Not Applicable dmi.product.name: W230SS dmi.product.version: Not Applicable dmi.sys.vendor: Notebook version.compiz: compiz 1:0.9.13.1+18.04.20180302-0ubuntu1 version.libdrm2: libdrm2 2.4.95-1~18.04.1 version.libgl1-mesa-dri: libgl1-mesa-dri 18.0.5-0ubuntu0~18.04.1 version.libgl1-mesa-glx: libgl1-mesa-glx 18.0.5-0ubuntu0~18.04.1 version.xserver-xorg-core: xserver-xorg-core 2:1.19.6-1ubuntu4.2 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.5-1ubuntu1 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:18.0.1-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20171229-1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.15-2 xserver.bootTime: Mon Oct 1 13:12:45 2018 xserver.configfile: default xserver.errors: Failed to load module "nvidia" (module does not exist, 0) Failed to load module "nvidia" (module does not exist, 0) NOUVEAU(G0): [XvMC] Failed to initialize extension. xserver.logfile: /var/log/Xorg.0.log xserver.version: 2:1.19.6-1ubuntu4~16.04.1 xserver.video_driver: modeset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1814387/+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
