I have the Acer C7 Chromebook running Ubuntu 13.04. In Chrome OS you put both fingers on the mousepad ( I guess that's name.. ) to right click, well in Ubuntu you have to click on the right side of the pad and sometimes it gets hard do a double-finger scroll. I was hoping ( even though this should be in Ubuntu forums ) if someone could help out. It's not a rare problem in chrubuntu that I've noticed but if there is a fix I'd be grateful! When I get home I'll try to work on the issue when I get the chance and hopefully try to get in double finger right-clicking with the scrolling :(.
