I am having trouble with the touch pad on my laptop. Most of the time it works fine, when I slide my finger across it moves the mouse cursor. Often though the cursor will freeze in place for 5 seconds or so, particularly when I am browsing the web. Right now I am using Ubuntu 14.10, but this problem also happens on the latest Fedora and Debian testing. The problem happens in gnome, xfce, and unity. When the touchpad stops working the right and left click buttons still work and the keyboard still works. Everything else seems to keep working also, I can alt-tab to another window or switch to another virtual console etc. After a few seconds it will resume normal functionality, but this happens often enough that it is very annoying.

I am not sure how to better describe the problem. Can you all help me figure out what is going on?

Which graphics chipset and driver is in use? This *might* be a graphics driver issue, rather than a touchpad issue. Can you replicate this issue when using an external mouse for example?

Using an external USB mouse works fine. There are no hangups or stuttering.

I guess it could be due to a kernel regression. Was this hardware working okay at some time prior? Do you have an older Live distro to try?

Information from the following could be useful
Check for any existing bug reports concerning this behaviour or submit a bug report if necessary.

Hi,

Be sure to look at: /var/log/Xorg.0.log and dmesg plus other logs to see what is going on.
Hope this helps.
Have fun & enjoy!
