I've been using Ubuntu from a long time and recently I have shifted to its newest version 11.10. Its interface is nice but my touch-pad hangs frequently in short intervals of time. When that happens, no key or key combination works. The only option is to restart or logout my laptop. I am using a Dell Inspiron N4010.

I have tried a lot to solve this problem but haven't found any satisfactory help till now. Most of my friends who are using Ubuntu 11.10 reported the same to me, seems like it's a bug.

How can I get out of this problem?

More detail is better, like what kind of touchpad... – soandos Nov 27 '11 at 16:05

Have you updated your Ubuntu? Update will be a good option. I have had issues with the unity desktop and compiz, So i installed gnome and nautilus instead and removed compiz. That seems to have helped.

To install gnome

sudo apt-get install gnome-shell

nautilus also can be installed similarly.

sudo apt-get install nautilus.
