When I hit the button a desktop notification appears, informing me that the device has been disabled (an icon of a touchpad with an x in the bottom-right-hand-corner) and I am no longer able to use the touchpad for anything, as expected. When I press the button again to re-enable the touchpad, a desktop notification appears, informing me that the device has been enabled (an icon of a touchpad with no x in the bottom-right-hand-corner) but the touchpad remains disabled, i.e I can use it for absolutely nothing. (clicking, scrolling, pointing, ...) Re-logging or restarting the laptop enables the touchpad, but I can also use modprobe to remove and insert psmouse module, which will also cause it to enable. When I use the button physically next to the touchpad to enable/disable the touchpad, it does not affect the toggle switch in the "Mouse and Touchpad" settings, but if I use that setting (the toggle switch) I can correctly enable and disable the touchpad. xinput lists the device under "Virtual core pointer" as an "AlpsPS/2 ALPS GlidePoint". BIOS is updated as of today. If I can be of help in patching the bug, I would love to, but I just have no idea where to look. I altered the psmouse kernel module to print information to the logs about various activity (resetting, deactivating) but none of it was very informative (again, I don't know where to look). --- ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: benjamin 1617 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 15.10 HibernationDevice: RESUME=UUID=7b71d0e9-05b0-4b07-9cd1-e4a998e8be54 InstallationDate: Installed on 2015-11-23 (0 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) MachineType: Acer Aspire 5738 Package: linux (not installed) ProcFB: 0 nouveaufb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.2.0-18-generic root=UUID=c2650be5-50b4-4182-a8e7-c428326ae23e ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 4.2.0-18.22-generic 4.2.3 RelatedPackageVersions: linux-restricted-modules-4.2.0-18-generic N/A linux-backports-modules-4.2.0-18-generic N/A linux-firmware 1.149.2 Tags: wily UdevLog: Error: [Errno 2] Ingen sådan fil eller filkatalog: '/var/log/udev' Uname: Linux 4.2.0-18-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 09/24/2010 dmi.bios.vendor: Phoenix Technologies LTD dmi.bios.version: V1.34 dmi.board.name: JV50_MV dmi.board.vendor: Acer dmi.board.version: Rev dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: N/A dmi.modalias: dmi:bvnPhoenixTechnologiesLTD:bvrV1.34:bd09/24/2010:svnAcer:pnAspire5738:pvr0100:rvnAcer:rnJV50_MV:rvrRev:cvnAcer:ct10:cvrN/A: dmi.product.name: Aspire 5738 dmi.product.version: 0100 dmi.sys.vendor: Acer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1518737/+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
