I continued with this. Bug happens with kernel 3.2.0-49 (newest for precise)
Bug happens with kernel 3.10.1 (newest for saucy) Restarting Xorg is not enough to bring touchpad to life, full reboot is needed. Debug build (for debug messages) of xserver-xorg-input-synaptics doesn't show any messages when hardware-button is pressed. synclient touchpadoff=1 and synclient touchpadoff=0 and synclient touchpadoff=2 and synclient | grep -i touchpadoff are working as expected. When touchpad is disabled with hardware-button "synclient | grep -i touchpadoff" still shows 0. I attached screenshot of overlay icon for disabled touchpad. I think it comes from package gnome-settings-daemon and more precisely it is shown by this file: plugins/media-keys/gsd-media-keys-manager.c ** Attachment added: "touchpad_icon_disabled.png" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1037085/+attachment/3736655/+files/touchpad_icon_disabled.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1037085 Title: 'disable-touchpad'-hardware-key is not enabling touchpad again To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1037085/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
