Hi, we have the same issue regarding the firmware ID, as other reported earlier. We have new T550 systems, which have the following firmware ID:
# cat /sys/devices/platform/i8042/serio1/firmware_id PNP: LEN002c PNP0f13 When adding a corresponding udev rule for this firmware ID to set the udev tag, the Xorg synaptics driver get configured correctly, and the buttons behave as they should. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1414930 Title: [Lenovo ThinkPad X1 Carbon 20BT] Buttons of Synaptics trackpad doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1414930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
