[Bug 1594214] Re: ETPS/2 Elantech Touchpad inconsistently detected (Gigabyte P57W laptop)


@penalvch: I would *love* to run `apport-collect`, but doing so causes
my entire system to lock-up. So does running `lspci` more than 80% of
the time, which will be a tale for another bug report.

Using skylake hardware is proving to be a real adventure. :/

Is there a way to run apport-collect and choose what information it
gathers, so I can restrict it to non-crashy commands only? I'm not yet
on a 4.6 kernel (which apparently has much better skylake support), and
4.4 seems to require a gentle touch.
