This concerns a fresh install of Mga6 64-bit Plasma on a laptop with an AlpsPS/2 ALPS DualPoint TouchPad (according to MCC). The touchpad works as such, including mouse click emulation, but most of the options under touchpad in the Plasma system settings are shaded out and can't be adjusted. I would like to change tap detection times, sensitivity and speed, but can't.
In Mga5 copying in /usr/share/X11/xorg.conf.d/50-synaptics.conf from a ROSA live disk, where tap-to-click worked, solved the issue. That approach doesn't work this time. In addition to ./50-synaptics.conf, I copied ~/.kde4/share/config/touchpadrc from Mga5 to ~/.kde/share/config/touchpadrc in Mga6, but there seems to be no change either way.
Are there any configuration files that I have missed? Any suggestions would be much appreciated. I find having the touchpad set just right is crucial.
Thanks.
