My girlfriend has found a cheap second-hand Sony Vaio laptop, which has been working great with Ubuntu, except for not having two-finger scrolling and suspending it causing it to reboot. We dug a little bit and ended up finding out how to enable the two-finger scrolling.
It’s pretty simple, so we just created a script that gets executed on startup:
If it scrolls when you want the cursor to move, increase the MinZ value. If it moves the cursor when you want it to scroll, decrease the value. Simple!
