Problem resolved upstream -- details here: https://bugs.freedesktop.org/show_bug.cgi?id=88609
An easier temporary workaround is to create a file in /etc/modprobe.d/ called psmouse.conf and put the following line in it: options psmouse proto=imps Then do sudo update-initramfs -u I'm hopeful that the patch from freedesktop.org will be backported to Trusty's kernel soon. ** Bug watch added: freedesktop.org Bugzilla #88609 https://bugs.freedesktop.org/show_bug.cgi?id=88609 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1431931 Title: T450s thinkpad physical buttons not configured properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1431931/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
