For those running Ubuntu on CR-48

[Rich]

Latest update to dev channel Chrome OS has a newer kernel. Following
the update, if you copy the module files and update the kernel in /dev/
sda6 , the synaptic drivers work! Multitouch is a little screwy, but
side scrolling works, and two button right click works.

Thanks for the tip, I plan to reinstall Ubuntu a bit later today.
Needed to reload the stock image to test something else the other day and lost Ubuntu.

Can someone explain how to do this with a little more detail?

Thanks.

Thanks. I already have ubuntu installed. Is it necessary for me to
reinstall it to get the touchpad working?

only need to upgrade the KERN-C Partition with the latest kernel release from the cros developer channel and update the modules.

Probably noob question here:

How would I go about upgrading the KERN-C partition and the modules? I
too have Ubuntu installed which I did before switching to the dev
channel (which I have done now - got an update and rebooted Chrome
OS).

In addition would simply running the the auto-install script and
installing Ubuntu again make things work?

Thanks.

If you dd the active partition to KERN-C and then make_install using
the same kernel parameters as specified in the Google documentation,
everything should work. Basically follow the instructions on the
documentation proceeding the mounting of the Ubuntu partition to /tmp/
urfs.
