This is a 17/3'' Intel (Core i7 second gen 2670QM) laptop with nVidia Geforce GT540M CUDA 1GB grphics card. I have regular Ubuntu 12.04 (with Unity) on it.

Issue #1 (very annoying): when I type, the cursor jumps randomly to whereever the mouse pointer is. I have selected "disable touchpad while typing" option in the mouse controls, but it does not help.

Issue #2: Suspend and Hibernate do not work. The screen goes blank but the backlight stays on and the machine remains powered up.

Any help will be greatly appreciated.
