For awhile now (including in Ubuntu 10.10 and 11.04), I've experienced an issue with scroll events initiated on my Touchpad. Steps to reproduce are: 1) Open Firefox 2) Start a vertical scroll event on Touchpad (two-finger scroll, in my case) 3) Quickly hit ctrl
The results are that Firefox will start zooming in or zooming out the page. I also experience this if I start a scroll event and quickly switch to a different workspace -- where my Terminal will start scrolling up or down. I would expect that the scroll event would die as soon a meta key is hit.
I'm on a Thinkpad W510 on Ubuntu 11.04 using Unity. Here's all the info I can find on my Touchpad:
