Re: PROBLEM: Touchpad works just like a mouse

["David Zafra Gómez" <dezeta@klo.es>]

Hi Hans

Sorry for the delay.

I'm afraid I haven't built a kernel before, so I need some help.

I've found this link I think describes what I have to do
https://www.kernel.org/doc/Documentation/applying-patches.txt
I suppose it's right.

I've installed kernel 4.0.0-040000rc6.201503291935. So I suppose I have 
to download sources for this kernel.

Once downloaded, I have to change to the kernel source dir and run:
$ patch -p1 < 
../0001-elantech-Fix-detection-of-touchpads-where-the-revisi.patch

Is all that right?

If yes, should I compile this patched kernel? How can I do it?

Thanks in advance.
