Public bug reported: Booting from a Lubuntu Trusty Live disc on a Lenovo 3000 C200 laptop with a Synaptics touchpad, double-tap to open a file or folder works sporadically/erratically/badly. It often requires a VERY fast double- tap, or a very fast double-tap with extra force, but even these measures may not work.
Via synclient, I played with the FingerLow, FingerHigh and MaxDoubleTapTime settings, but did not arrive at something that worked. I did eventually discover that a *triple-tap* reliably yields the behavior I would expect from a double-tap. I found the same behavior under Lubuntu Saucy installed on the hard drive, and under Lubuntu Live discs for older versions at least back to Lubuntu 12.10. I also booted a Lubuntu Trusty Daily Build Live disc on an HP Elitebook 8530p with a Synaptics touchpad and likewise found the bad behavior there, though somewhat lessened. Perhaps due to the faster Core 2 Duo processor? Booting an *Ubuntu* Saucy Live disc on the Lenovo, double-tap worked as expected. Double-tap also worked as expected on this machine under Windows Vista. On another laptop with Lubuntu Saucy but an ALPS touchpad, double-tap worked as expected. In accord with http://wiki.ubuntu.com/Debugging/TouchpadDetection (the section "Touchpad features work, but does not work correctly and as expected"), I will include xmodmap, xinput, evtest and xev attachments in a logs.tar.gz archive. For evtest and xev, I tried to capture a single double-tap between typed letter "a" identifiers. I filed a similar bug for Lubuntu Saucy: # 1286326 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xserver-xorg-input-synaptics 1.7.3-1ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-8.27-generic 3.13.2 Uname: Linux 3.13.0-8-generic i686 ApportVersion: 2.13.2-0ubuntu2 Architecture: i386 CasperVersion: 1.337 CurrentDesktop: LXDE Date: Fri Feb 28 22:10:03 2014 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu LiveMediaBuild: Lubuntu 14.04 "Trusty Tahr" - Alpha i386 (20140212) MachineType: LENOVO 892201U ProcKernelCmdLine: file=/cdrom/preseed/username.seed boot=casper initrd=/casper/initrd.lz quiet splash -- SourcePackage: xserver-xorg-input-synaptics UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/30/07 dmi.bios.vendor: LENOVO dmi.bios.version: 63ET62WW dmi.board.name: CAPELL VALLEY(NAPA) CRB dmi.board.vendor: LENOVO dmi.board.version: Not Applicable dmi.chassis.type: 10 dmi.chassis.vendor: No Enclosure dmi.chassis.version: N/A dmi.modalias: dmi:bvnLENOVO:bvr63ET62WW:bd04/30/07:svnLENOVO:pn892201U:pvr3000C200:rvnLENOVO:rnCAPELLVALLEY(NAPA)CRB:rvrNotApplicable:cvnNoEnclosure:ct10:cvrN/A: dmi.product.name: 892201U dmi.product.version: 3000 C200 dmi.sys.vendor: LENOVO version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.52-1 version.libgl1-mesa-dri: libgl1-mesa-dri 10.0.1-1ubuntu2 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.0.1-1ubuntu2 version.xserver-xorg-core: xserver-xorg-core 2:1.15.0-1ubuntu4 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.8.2-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.3.0-1ubuntu2 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.910-0ubuntu1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.10-1ubuntu2 xserver.bootTime: Fri Feb 28 20:57:24 2014 xserver.configfile: default xserver.devices: input Power Button KEYBOARD, id 6 input Video Bus KEYBOARD, id 7 input Power Button KEYBOARD, id 8 input AT Translated Set 2 keyboard KEYBOARD, id 9 input SynPS/2 Synaptics TouchPad TOUCHPAD, id 10 xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 9297 vendor AUO xserver.version: 2:1.15.0-1ubuntu4 ** Affects: xserver-xorg-input-synaptics (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug double-tap i386 lubuntu synaptics touchpad trusty ubuntu ** Attachment added: "logs.tar.gz" https://bugs.launchpad.net/bugs/1286372/+attachment/4001420/+files/logs.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1286372 Title: In Lubuntu, Synaptics touchpad double-tap to open works badly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1286372/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
