touchpad does not work on Asus X450L

Solution 1:

The only solution right now is to use an external mouse. (May be outdated?)

I currently have the same problem with my Asus X450CC, and sadly have not been able to find a solution yet.

Other users with X550CA / X550LC seem to have the same problem too.

Someone filed
launchpad bug 1314198: [Asus X550LC] Touchpad not Recognized in ubuntu 14.04 Edi,
and you can subscribe to it to be notified when something new on this issue is posted.

The interesting comment on the bug is #31:

[...] 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.

Solution 2:

Upgrading the bios solved the problem for me.
