Sony VAIO VPC-S12L9E/B TouchPad not working

[karry]

Dear colleagues,

That's my first post...I've recently bought a VAIO S12 series, unfortunately it does not work "out of the box" with 10.04 but I've fixed many issues.

The biggest problem I have by the moment is within touchpad as it's not working.

Do you have any idea about how to fix it?

Thanks in advance!

Hello karry, welcome aboard....

Same pb with my VPC-S12V9E and an up-to-date ubuntu 10.10

Solution:

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

Now my touchpad work's great....

Thank you Zecapistolas,

in the mean time I found the same fix in another thread, except that there was only i8042.nopnp to add,
and it works. Do you know what the other stuff i8042.reset, nomux, noloop do for you?

Yes, with only i8042.nopnp touchpad work's....

No, i don't know what is i8042.reset, nomux, noloop...

OK so I will stick to the minimal change.

I still have two pbs with my installation and I have started a new thread that might be relevant to you also:

It worked for my VPCS12L9E...thanks very much!!!! but now I have many other things to fix...microphone, bluetooth...do you have same problems?

I was more asking how you do this
Edit /etc/default/grub to include GRUB_CMDLINE_LINUX="i8042.reset i8042.nomux i8042.nopnp i8042.noloop
as i get very confused sometimes. Does anyone know, or can make it more simple for me. Thanks so much.
