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.

It would be helpful if you would edit your question to include the graphics card in the laptop, what driver you are using, what interface (unity ?), and what version of Ubuntu. You can check the logs for errors. –  bodhi.zazen Jan 4 '12 at 23:26
    
Please edit and add output of cat /etc/lsb-release , uname -a and lspci ? –  viyyer Jan 5 '12 at 3:09
    
Radical but efficient: i've disabled the touchpad using the following command: "xinput set-prop 14 "Device Enabled" 0", and created a launcher for it. It seems to work. –  Yarchmon Jan 15 '12 at 16:16
