[QUOTE=[COLOR=Red]BlueDragonX;10889524]I've not been able to reproduce either of these issues. How are you holding your fingers? I need to know how much pressure (roughly) you're putting on the pad, how close your fingers are together, and at what angle you're touching.[/COLOR]
Upscrolling definitely seems a bit harder for me. The stock driver in 11.04 did not have such issues. But boy, changing my xorg.conf file to post #30's settings really improved things alot.
Resting the thumb along the bottom edge of the trackpad and moving the cursor with your index finger no longer confuses the trackpad. But regarding upscrolling, i use my right hand. My thumb is resting on the bottom edge of the trackpad (so a thumb touch should be registered), and then with my index and middle finger, I scroll up and down. So while scrolling up and down, I've got 3 fingers touching the trackpad. For upscrolling, my index and middle finger are 1 cm apart, and the middle fingertip is above the index finger's fingertip. Not directly above, but above and to the right a bit. I scroll up with "\" motion (starting from the bottom of the aforementioned slash, and moving say from the 5 o'clock to the 10 o'clock position. I tend to use light pressure when scrolling.
But interestingly, upscrolling in an almost purely vertical motion doesn't seem to improve things. But all in all, the settings do make a difference.
I also added an IgnorePalm "True" to the xorg.conf file.
