Through debugging, I found when the lid was closed, the system/kernel will generate a TOUCHPAD_KEY (XF86TouchpadToggle) by a mistake, the gnome-settings-daemon->media-keys-plugin will capture this key and toggle the touchpad enable/disable through gnome-settings-daemon->mouse- plugin.
On other machines, closing lid won't generate TOUCHPAD_KEY event, so the touchpad doesn't has this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1089105 Title: [Lenovo V480c Notebook]: System fails to resume properly from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1089105/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
