[Bug 1445179] Re: Trackpad not detected
Zane Hitchcox, the next step is to fully reverse commit bisect from
kernel 3.16 to 4.0 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?
Please note, finding adjacent kernel versions is not fully commit
bisecting.
Thank you for your understanding.

Title:
Trackpad not detected
Status in linux package in Ubuntu:
Incomplete
Bug description:
Using Acer C720. The model is PEPPY C5A-R3E-A7B. I installed ChrUbuntu
following these
instructions:https://www.linux.com/learn/tutorials/764181-how-to-
install-linux-on-an-acer-c720-chromebook
I cannot connect to the internet on the ubuntu computer, because of
not having a trackpad and thus cannot send a bug report through the
ubuntu-bug linux thing.
I followed this debugging guide:
https://wiki.ubuntu.com/DebuggingTouchpadDetection/evtest
and there is no input device called "SynPS/2 Synaptics TouchPad" or anything like that.
