Hi All,
THE PROBLEM:
I've been running 12.04 for a few months, and have had a problem since my install with my laptop's touchpad. I've just ignored the problem until now, but since I'm spending most of my time on my Ubuntu partition these days, it's a problem I'd like to fix.
When using the touchpad, the mouse is incredibly imprecise: the minimum horizontal distance I can move it is about 1.5 mm (the vertical jump is a bit better, which I think is a product of the larger x-component in the 16:9 resolution), which is an incredibly big jump on my small laptop screen.
I do not have the same problem with other input, including the built-in Wacom Pen and the trackpoint, which are both capable of moving very small distances.
The overall mouse experience is pretty bad: I'll often click on the wrong link in a webpage, or launch the wrong application because of this issue. Any thoughts on what to do are very much appreciated!
WHAT I'VE TRIED:
- Adjusting different mouse sensitivity and acceleration settings. There has been no change in mouse jumpiness between different settings.
- Using other inputs. The problem seems to only affect the touchpad, which is my preferred mouse input device
- Looked online for similar problems. I found one for a similar problem that I also have at: http://www.iovene.com/1016/ and attempted his solution, without success.
