Hello. has anyone had luck getting the touchpad working in a chromebook acer c720 with the linux-libre kernel 3.13.5? I tried with the generic kernel and it did work but i want to keep my Trisquel free. Can someone please give me a script for the kernel? Thank you.

Your best bet would be by using the latest linux-libre kernel:

I suppose you installed full-disk? Also check here:

If you used the generic kernel from Trisquel's repository and it worked, it is completely free. So there's no need to use the libre kernel from jxself's repository.

I didnt use the trisquel's kernel, i used the one that you can download from https://www.kernel.org/‎. Making my trisquel not free... But now im on a fresh install with the latest linux-libre kernel (3.13.5) and i would like to patch it so i can use my touchpad. Thank you for your answers.

If it works on the vanilla Linux but not on the same version of Linux-libre, then it probably requires a blob. The policy of this community is to never help anyone install proprietary software (because that is not "helping").

The patches are at [0]. They are free (no blobs inside, they modify
GPL2-licensed files with the original patches having Signed-off-by).

The script included in that repo uses blobbed kernel sources. A proper
solution would be to apply the patches to Linux-libre kernel sources and
build it, Jason Self wrote that he will do it for next freesh kernel
updates.

Could you try installing the package linux-image-generic-lts-saucy? This is a deblobbed version of the Ubuntu saucy kernel. I know that Ubuntu applies some patches, so maybe they applied the patch for your touchpad.

If you (leoleo11) want a recent linux-libre kernel (compiled from source) you can follow these instructions: https://trisquel.info/en/wiki/compiling-gnu-linux-libre-kernel

The version of the kernel Linux from kernel.org isn't linux-libre. It contains non-free firmware "blobs".

Ok, I installed linux-image-generic-lts-saucy however i dont know where to get the script fro patching it. Any ideas?

OK, if it still doesn't work, then compile the kernel yourself. It's not too hard.

wget http://linux-libre.fsfla.org/pub/linux-libre/freesh/linux-libre-3.13.5-source.tar.xz
tar -xJvf linux-libre-3.13.5-source.tar.xz
cd linux-libre-3.13.5-source/linux
for patch in 3078491 3078481 3074391 3074441 3074421 3074401 3074431 3074411; do
wget -O - https://github.com/raouldc/c720-touchpad-patches/raw/master/$patch.patch | patch -p1
done
cd ..

Then follow the directions in README. Obviously, use the x86-64 config if you have 64-bit and x86-32 if you have 32-bit. You can run 'arch' in a terminal to find out.

Well i tried the instructions posted above and i can't get it to work. Is there a way to patch my already installed linux-libre kernel version 3.13.5? Maybe modyfying the commands already posted here? Thank you.

What did you try, and what doesn't work? What error messages did you get?

I think there was a captcha, unfortunately it didn't stop spammers.
