Just in case someone experience the same issue than me (or probably same than Dave earlier too), i.e. the touchpad is recognized by the new kernel, but then stops working again... I installed 3.16-1 and the problem persisted. However, I just realized that I still had some psmouse dkms module installed from a previous try at fixing the issue.
I just ran: <quote> sudo dkms remove -m psmouse -v elantech-x551c --all sudo rmmod psmouse sudo modprobe psmouse</quote> And the scrolling is miraculously back! Let's just hope it persists after reboot. No one else has complained in a while... maybe this bug should be tagged as fixed? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1272777 Title: Elantech touchpads not fully supported for some Gigabyte laptops Status in The Linux Kernel: Unknown Status in “linux” package in Ubuntu: Confirmed Bug description: This bug report is in addition to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1166442 - the fixes suggested there (which work for others) have been tried but do not work for a small subset of laptops, particularly the Gigabyte U2442 series. Description of the situation for my Gigabyte U2442V most recently running 3.11.0-12-generic on Linux Mint. I tried the updated module mentioned in the above bug report (1166442). It compiles and it detects an Elantech trackpad of *indeterminate version*. I get this in dmesg: [859697.496141] psmouse serio1: elantech: assuming hardware version 3 (with firmware version 0x450f01) [859697.526011] psmouse serio1: elantech: Synaptics capabilities query result 0x58, 0x17, 0x0c. [859697.765917] psmouse serio1: elantech: retrying ps2 command 0x0b (2). [859698.470556] psmouse serio1: elantech: retrying ps2 command 0x0b (1). I get no Synaptics driver functionality, and only basic touchpad behaviour (motion and tap-to-click for left click, no scroll or disabling the pad when typing, etc.). It seems I don't have a v9 or v10 trackpad, I've never been able to get a definitive indication of which version I have got. The only thing that has remedied this problem for me in the past was the one described in the original bug report (for elantech-v6 - https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/681904/comments/64)... but it no longer applies to newer kernels... With the 3.11.0-12-generic kernel, my Touchpad *is* detected, i.e. xinput shows: ↳ PS/2 Elantech Touchpad id=16 [slave pointer (2)] and dmesg shows: input: PS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input14 There are no useful touchpads settings evident in the normal Cinnamon settings utility (gnome-control-center -> Mouse & Touchpads). I see a touchpad settings option with the "gpointing-device-settings" app and I can turn on vertical and horizontal scrolling in the interface, but doing so does not in any way affect that actual touchpad behaviour. I've also tried installing the elantech-v7 module via dkms (see http://ubuntuforums.org/showthread.php?t=2111236&p=12850603#post12850603) and it compiles, but it too fails to provide the desired functionality. --- ApportVersion: 2.12.5-0ubuntu2.2 Architecture: amd64 DistroRelease: Ubuntu 13.10 HibernationDevice: RESUME=UUID=29b0358f-f728-4aea-bce5-e233816f27b1 InstallationDate: Installed on 2013-12-11 (46 days ago) InstallationMedia: Linux Mint 16 "petra" - Release amd64 20131126 MachineType: GIGABYTE U2442 MarkForUpload: True Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.11.0-12-generic root=UUID=83fd94b8-53eb-4e68-9eeb-cf2e017cbe0d ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.11.0-12.19-generic 3.11.3 RelatedPackageVersions: linux-restricted-modules-3.11.0-12-generic N/A linux-backports-modules-3.11.0-12-generic N/A linux-firmware 1.116 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Tags: petra Uname: Linux 3.11.0-12-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo dmi.bios.date: 10/26/2012 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: U2442.F306 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: U2442 dmi.board.vendor: GIGABYTE dmi.board.version: To be filled by O.E.M. dmi.chassis.asset.tag: To Be Filled By O.E.M. dmi.chassis.type: 10 dmi.chassis.vendor: To Be Filled By O.E.M. dmi.chassis.version: To Be Filled By O.E.M. dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrU2442.F306:bd10/26/2012:svnGIGABYTE:pnU2442:pvrTobefilledbyO.E.M.:rvnGIGABYTE:rnU2442:rvrTobefilledbyO.E.M.:cvnToBeFilledByO.E.M.:ct10:cvrToBeFilledByO.E.M.: dmi.product.name: U2442 dmi.product.version: To be filled by O.E.M. dmi.sys.vendor: GIGABYTE To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1272777/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
