Trying evtest (http://www.freedesktop.org/wiki/Evtest) on my SynPS/2 Synaptics TouchPad which had always been working with previous kernel versions no events are generated for /dev/input/event1. Also the synaptic driver for Xorg and the console driver gpm on /dev/psaux do no more react on touchpad events.

What was the last kernel version where the touchpad worked? Also, 3.4.6-1.1 is not a mainline version, what distribution is this?
Comment 2 Elmar Stellnberger 2012-08-22 20:33:38 UTC
Oopsla. In spite of what the people at freedesktop.org have argued there was also a configuration issue (https://bugs.freedesktop.org/show_bug.cgi?id=53873). Still I wonder why evtest did report nothing. (Well it worked with openSUSE 12.1 but the difference made a special synaptic configuration to oS 12.2 RC2).
Comment 3 Elmar Stellnberger 2012-08-25 09:36:46 UTC
Everything fine on the kernel level! I think something else had confounded evtest at my first trial to run it (hopefully not a kernel race condition). Nonetheless as programs like Xorg affect to grab all keys including the console switcher [Ctrl][Alt][Fx] I would adore some SysRq keys for console switching like [Alt][Druck][F1] perhaps. I think it has produced us some unnecessary work at freedesktop.org because an infunctional [Ctrl][Alt][Fx] accompanied by a forground program that does not process keystrokes correctly looks like a total system hangup and may be reported as such - The SysRq-KillForegoundProcess does according to my experience not help out either because Xorg doesn`t like it (just makes my system crash and does not re-map console keys).
