I recently installed Ubuntu 10.10 Maverick in my Sony Vaio E series laptop (VPCEB46FG) and its working just great. After installing, i got frequent net disconnection issues which i fixed as mentioned in my previous post. The next issue was with the touch pad and i had to find a way to make it work. This is how i managed to fix it:
Open terminal and type the following:
sudo gedit /etc/default/grub/
Note: If you get error stating Grub: File not found (missing)
sudo gedit /boot/grub/grub.cfg
Edit the line
GRUB_CMDLINE_LINUX=” “
and add
GRUB_CMDLINE_LINUX=”i8042.nopnp”
Now run:
sudo update-grub
and finally reboot. Thats it! Your touchpad is ready with multitouch

Dear friend’
I had the same problem on Ubuntu 10.10 and I solved it in this way:
sudo gedit /etc/default/grub/
Edit the line:
1.GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
to
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash i8042.reset i8042.nomux i8042.nopnp i8042.noloop”
2.GRUB_CMDLINE_LINUX=” ”
to
GRUB_CMDLINE_LINUX=”i8042.nopnp”
and then:
sudo update-grub
sudo reboot
have fun
