Public bug reported: I'm on Lenovo T450s, but there are reports of others having the same problem that touchpad disabling, which is no longer an explicit option, is not working. This leads to data loss and frustration when typing/editing, etc.
With default settings, I find that syndaemon has been run with the following options: $ ps aux|grep synd meuser 2798 0.0 0.0 22504 2784 ? S Jul15 0:02 syndaemon -i 1.0 -t -K -R However, this fails. My palms/ base of my thumbs, in particular, hover over my touchpad while typing and frequently cause unintended motion AND mouse-click events, highlighting and deleting text, switching windows, etc. The diagnosis seems to be (http://askubuntu.com/questions/299868 /disable-touchpad-while-typing-does-not-work) that the -t option is not working, ie mouse clicks are still allowed when it is called. The following two commands are a work-around for me under 16.04 on this hardware. They result in perfect touchpad disabling while typing: killall syndaemon syndaemon -i 1 -KRd ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xserver-xorg-input-synaptics 1.8.2-1ubuntu3 ProcVersionSignature: Ubuntu 4.4.0-31.50-generic 4.4.13 Uname: Linux 4.4.0-31-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 CurrentDesktop: Unity Date: Sun Jul 17 12:17:26 2016 DistUpgraded: 2016-05-24 18:07:00,267 DEBUG icon theme changed, re-reading DistroCodename: xenial DistroVariant: ubuntu EcryptfsInUse: Yes InstallationDate: Installed on 2016-02-12 (155 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) MachineType: LENOVO 20BXCTO1WW ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-31-generic.efi.signed root=UUID=ea2fb511-8d62-4b96-bdaa-4b3f7bf79cc6 ro noprompt quiet splash vt.handoff=7 SourcePackage: xserver-xorg-input-synaptics UpgradeStatus: Upgraded to xenial on 2016-05-24 (53 days ago) dmi.bios.date: 11/06/2015 dmi.bios.vendor: LENOVO dmi.bios.version: JBET54WW (1.19 ) dmi.board.asset.tag: Not Available dmi.board.name: 20BXCTO1WW dmi.board.vendor: LENOVO dmi.board.version: SDK0J40697 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrJBET54WW(1.19):bd11/06/2015:svnLENOVO:pn20BXCTO1WW:pvrThinkPadT450s:rvnLENOVO:rn20BXCTO1WW:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: dmi.product.name: 20BXCTO1WW dmi.product.version: ThinkPad T450s dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.12.2+16.04.20160526-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.67-1ubuntu0.16.04.1 version.libgl1-mesa-dri: libgl1-mesa-dri 11.2.0-1ubuntu2 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 11.2.0-1ubuntu2 version.xserver-xorg-core: xserver-xorg-core 2:1.18.3-1ubuntu2.2 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.1-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.7.0-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20160325-1ubuntu1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.12-1build2 xserver.bootTime: Fri Jul 15 21:21:11 2016 xserver.configfile: default xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 20104 vendor GSM xserver.version: 2:1.18.3-1ubuntu2.2 ** Affects: xserver-xorg-input-synaptics (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug ubuntu xenial -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1603791 Title: syndaemon "-t" option fails, in turn making touchpad disable while typing not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1603791/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
