My friend has a new Asus G53SW notebook with Ubuntu Oneiric installed. Sometimes the touchpad is weird and hangs around or you can't click on things. It's quite unusable.
How can I fix this weird behaviour, are there any "drivers" for the touchpad?
Install the package synaptics-dkms and configure in System > Preferences > Mouse, under the Touchpad tab.
Try the touchpad after unchecking the Enable mouse clicks with touchpad check box.
Check operation after Enable horizontal scrolling is checked. This may not have been the default setting.
The weird behaviour was from Grab Handler in CCSM.
So I just disabled Grab Handler and now it works fine.
