Temporary fix for Asus touchpad not detected under Ubuntu Linux

Hans de Goede posted the following comment on Launchpad bug #1323346:

Hi,

Fixing this is non trivial, supporting these new touchpads likely
needs a signicant amount of work (for details see
https://bugzilla.redhat.com/show_bug.cgi?id=1110011 ).

In the mean time, I can provide a workaround which should make the
touchpad work in ps/2 mouse emulation mode (so no 2 finger scrolling,
etc.), and stop it from interfering with an external mouse.

Sounds good? Try booting with "psmouse.proto=bare" on the kernel cmdline.

See: https://wiki.ubuntu.com/Kernel/KernelBootParameters for how to
add a parameter to the kernel commandline.

Regards,

Hans

To test this workaround, do the following:

$ sudoedit /etc/default/grub

Change GRUB_CMDLINE_LINUX_DEFAULT to add psmouse.proto=bare at the end, and save your modifications.

Then:

$ sudo update-grub

And finally reboot.
