This is some maybe-not-relevant info: I thought I had the same problem, and while looking for solutions on the net I stumbled upon https://bugs.archlinux.org/task/20830. Extrapolating the workaround suggested there, I added
MatchDevicePath "/dev/input/event*" to /usr/share/X11/xorg.conf.d/50-synaptics.conf. Indeed it made lines like these go away: [ 6812.841] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/mouse0) [ 6812.841] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "touchpad catchall" [ 6812.841] (II) Synaptics touchpad driver version 1.2.2 [ 6818.510] SynPS/2 Synaptics TouchPad no synaptics event device found [ 6818.510] (**) Option "Device" "/dev/input/mouse0" [ 6818.610] Query no Synaptics: 6003C8 [ 6818.610] (--) SynPS/2 Synaptics TouchPad: no supported touchpad found [ 6818.610] (EE) SynPS/2 Synaptics TouchPad Unable to query/initialize Synaptics hardware. [ 6818.690] (EE) PreInit failed for input device "SynPS/2 Synaptics TouchPad" But there was no improvement in the operation of the driver. Apparently the workaround stops the second loading of the driver for /dev/input/mouse0, but in my case there's another earlier (for /dev/input/event7) which works just the same regardless of this failed one. So bottom line the workaround appears to be a red herring in my case, but I thought it could still be worth mentioning here. -- Synaptics TouchPad: no supported touchpad found https://bugs.launchpad.net/bugs/611992 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
