Fix for the Acer 532H Touchpad and Scrollbar in Ubuntu 10.04 Lucid Lynx

I came across a fix for the vertical scrollbar on the touchpad for my Acer 532H laptop in Lucid Lynx Ubuntu Remix. With a vanilla install of Lucid Lynx it does not work properly.  The vertical scrollbar allows you slide your finger up and down to move your web page up or down.

I found the fix on the Ubuntu Forums. Here are the steps to activate the change permanently on your Acer Laptop.  It involves adding a line to a file in the /etc/modprobe.d directory.

1. Open a terminal and open up the editor by  typing:  sudo gedit /etc/modprobe.d/psmouse.conf   and add this line to the file:

options psmouse proto=imps

2Then select  File  -- > Save  (saving the file in gedit)

Note that the psmouse.conf file does not exist and you are creating a new file in the /etc/modprobe.d directory.

Then Reboot.  The fix should be in place when your netbook is re-booted, as the psmouse.conf file will be read into the kernel when it restarts.
