I have a problem with the touchpad on my Toshiba Satellite L300. The mouse pointer does not respond when I move my finger quickly. If I start moving slowly, the pointer moves but then it becomes intermittent as I increase the speed of my finger. The system also does not detect single taps half of the time. I’ve had this problem in several versions of OpenSUSE, Ubuntu, and Linux Mint. The touchpad works flawlessly in Parted Magic, Chakra, and Windows. :\
I’m using the 32 bit version of OpenSUSE 11.4 with KDE 4.6.0. The touchpad is shown as “Synaptics PS/2.”
See what this command reports:
synclient -l
Post the results here. Maybe someone can offer more specific advice.
It is possible to change some of the timings associated with tapping etc
Type
man sysclient
for more info.

i’d suggest it is a hardware problem…
see if you can find a slower finger.

I tried adjusting FingerLow and FingerHigh but the problem is still here.
I get the following output when I move my finger at any speed.

Would the kernel version make a difference?
