Sony VAIO VPC-S12L9E/B TouchPad not working

The reason why you cannot edit the grub file is maybe that you were not root?
If this was the pb. use "sudo" before the edit command

This GRUB editting has fixed my friend's MSI VR630 laptop, too. Now his touchpad works just fine. Thanks!!

Dear Leshisky,

to edit grub, open a terminal (applications => system tools).
And type sudo nedit /etc/default/grub
Then you can add the command if it does not exist already.

For the others: I had many troubles with Ubuntu 10.4, so I decided to try the beta version Ubuntu 10.10. It worked fine (e.g. I could use Rosegarden with midi files, by typing timidity -iA first, I had the graphic card Nvidia and touchpad working right from the beginning). The GRUB_CMDLINE_LINUX="i8042.nopnp" was already included in Grub.

BUT - and this is the reason of my post - I tried many things, but I can't DEACTIVATE the touchpad. This seems to be a common problem. Maybe some of you will have a solution for the Sony Vaio... What I tried until now didn't work. I still can't see the touchpad in System => Mouse.

Any idea ?

Karry,

Did you manage to get the microphone working? I have a VPC-S12C7E and I have managed to get much of it working, but one of the things I would really like to use is the internal microphone and it doesn't work.

I am using VPC S12 C7E but the edge scroll, whilst a bit temperamental, works okay.

I'm getting this error when I put in

bash: /etc/default/grub: Permission denied

Does anyone know why my access is denied and how I can fix this?

[peertje888]

kkpickel: IMHO the thread is very clear on this...you have to open the file as super user, you can do this by using either su, sudo or gksudo. For example from shell:

sudo gedit /etc/default/grub

or from your desktop -> run application (Alt + F2)

gksudo gedit /etc/default/grub
