@PHLin Can you give the mainline kernel, e.g. http://kernel.ubuntu.com/~kernel- ppa/mainline/daily/2014-01-23-trusty/, a try? There is a patch in current mainline that probably fixes this bug.
commit c15bdfd5b9831e4cab8cfc118243956e267dd30e Commit: Dmitry Torokhov <[email protected]> CommitDate: Wed Dec 18 08:47:29 2013 -0800 Input: elantech - improve clickpad detection The current assumption in the elantech driver that hw version 3 touchpads are never clickpads and hw version 4 touchpads are always clickpads is wrong. There are several bug reports for this, ie: https://bugzilla.redhat.com/show_bug.cgi?id=1030802 http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux I've spend a couple of hours wading through various bugzillas, launchpads and forum posts to create a list of fw-versions and capabilities for different laptop models to find a good method to differentiate between clickpads and versions with separate hardware buttons. Which shows that a device being a clickpad is reliable indicated by bit 12 being set in the fw_version. I've included the gathered list inside the driver, so that we've this info at hand if we need to revisit this later. Firmware of this touchpad is 0x461f04, so bit 12 is 1. ** Bug watch added: Red Hat Bugzilla #1030802 https://bugzilla.redhat.com/show_bug.cgi?id=1030802 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1188025 Title: [Dell Vostro 5460] Right key on the touchpad is not working To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1188025/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
