The laptop that i am using is Sony Vaio VPCEE2M1E. I recently got my trackpad to work, but now i need to find a way to make my scrolling fuction to work!

Can anyone help me?

I tried all this:
1. Edit /etc/default/grub to include GRUB_CMDLINE_LINUX="i8042.nopnp"
2. Run: sudo update-grub
3. Reboot.
I also added i8042.reset i8042.nomux i8042.nopnp i8042.noloop
