I am on a fresh 12.10 install on a brand-new Lenovo Thinkpad X121e. The touchpad was already quite bad just after the installation, but now it is just too erratic to use...
Trying to move the mouse in a straight line, the mouse just wobbles erratically up and down, even when I try to hold my finger still. By eratically, I mean around 40px or 2-3 lines of text. The mouse is not jumping into corners like in this bug. Also, the trackpoint is very smooth.
It did work better once before, I suspect the issue arose first when I tried to
synclient AreaBottomEdge=5500. What can I try? Can I undo the changes
I also tried to deinstall the synaptics driver, without any difference. Should something have changed. Is there a way to up- or downgrade the firmware?
