The cursor sometimes goes wild, I get random clicks, the windows are resizing, the cursor disappears. In the worst case, clicks and keyboards are disabled.

I've tried the solution given on doc.ubuntu-fr.org and add tu grub :

i8042.nomux=1 i8042.reset=1 in GRUB_CMDLINE_LINUX_DEFAULT

But it didn't work

What can I do ?

• Graphic card : Geforce GTX460M.
• Ubuntu : 11.10 (64 bits).
• Laptop Asus G73sw

Interface : Unity (since 11.10) - didn't get this problem with Gnome before.
Complement: when a window is resizing, it gets drag-boxes at every corner, center of sides and center of the window. It looks like my touchpad sends random info, or like a "ghost" touchscreen.

Edit 01-09-12: Tried on Ubuntu 2D: the behavior is different: it's like i'm randomly clicking on the workspace switcher icon. In the worst case, it can happen several times in a minute.
