I have a gateway notebook, model LT3119u. (specs: http://www.gateway.com/systems/product/529668744.php
It came with Windows 7 original. No problems there. Mouse works well.
However, all linux distros that I tried (fedora 12; ubuntu 10.04, 10.10; mandriva) have the same problem. Mouse initially works well, but will suddenly jump around, click on its own, and simply go random.
This does not happen when I'm typing (I don't accidentally touch the touchpad when I'm typing). It happens only when I'm touching the touchpad. A slightest touch can cause the mouse to click on 20 different things, or jump around the screen in completely random speed and direction.
The only way to stop it, is to plug in a USB mouse. Then it goes back to normal and I can use the USB mouse. The trackpad will continue to misbehave.
Also, sometimes the computer boots up and the mouse works fine--until the machine goes to sleep. When it wakes up--mouse starts jumping and clicking again.
Please let me know what I can do. Linux is my primary work environment, mainly because of it's security and stability--and I would prefer to use it on the notebook more so than Windows 7.
PS. Currently I have Fedora 12 installed, however, this happens in Ubuntu as well.
