No change to touchpad status

[Akko1]

I have been trying this script recently on a new purchased c720 (UK) and following the advice here the touchpad does not work after rebooting. This is with kernel 3.13-1 which was updated through the rest of the process. Changing the wget parameter to this newer kernel or leaving the default produces the error http://pastebin.com/pRARSmYn
changing the wget to 3.12.5 or 3.12.6 does allow the script to process without error however the reboot does not load any touchpad driver. (I have also attempted the /etc/X11/xorg.conf.d/50-cros-touchpad.conf change)

could this just be the kernel version I have creating the issue since this process was created? (on a side note #! with chromeos using crouton works fine. just want to get the space back as have no use for chromeos. [also thank you for a great process!])

Thanks for your note - it is hard to say exactly, but my guess is it is related to the fact that since this guide was written, new kernels have been released that end up breaking things. A couple shots in the dark:

1. I found that the default touchpad settings were not nearly sensitive enough and I would need to press down pretty hard for it to sense movement. Does pressing harder help by any chance? When you type synclient what are the parameter values for FingerLow and FingerHigh?
2. What does it say when you enter uname -a in the terminal?

1. I must confess I did try a few fast swipes and could not be sure how much pressure I was applying. but it didn't seem to move at all but I did then try synclient and had an error that no synaptics driver was loaded.

2. 3.13.1

But I think you may be correct that the kernel has jumped ahead to a point its caused more issues.

My earliest thought on this was to restart the entire process and during the kernel upgrade process ensure its forced to 3.12.5 to smooth out the install process.

Any thoughts welcome.

Odd that synclient isn't working, though presumably that is part of the reason the touchpad isn't working.

As for potential fixes, I had a similar thought - doing a clean install again, but this time upgrading to a kernel like 3.12.5 instead of the latest kernel might help things. It does seem like a bit of an extreme solution, but I can't think of anything else at the moment, sorry. I would be very interested in whether this would fix things though, so please let me know if it works out for you though!

I shall be trying this most likely over the weekend period as I suspected the same and I'd say confirmed here http://www.reddit.com/r/CrunchBang/comments/21edoq/just_setup_on_acer_c720_chromebook_glad_to_be_back/ Once I have tested this I will let you know my exact change for the kernel update so you can tweak your process accordingly for future users :)

I have confirmed it is the kernel after now using 3.12.5 This can be quite easlier accounting for in your process by ensuring that just before anybody runs the c720crunchbangtp script they downgrade from whatever kernel they have upgraded too based on the procedure here for obtaining 3.12.5 then using the reversal to get it working http://elementaryforum.org/forum/support-assistance/how-to_aa/2878-mainline-kernel-upgrade-procedure

Thanks for the update! I will add a note in the guide to reflect this.
