I believe there need to be a new strategy to improve kernel debugging

Current expectation all users have same knowledge and understanding.
Best way of describing this speaking my car mechanic to about fix my
car. But mechanic expects me to connect a laptop to the car, google the
internet for 60 mins trying to find the program required to 'debug' and
finding workarounds when debug commands don't work

But mechanic dont do that. You drive it into the shop and they take care
of it. The car owner just wants it fixed

What I am suggesting there should be a simple way of recovering
intelligence to be used for kernel debugging or offering "secure" way of
a kernel debugger to offers complete their tests and commands remotely

I am a novice user when comes to kernel debugging and commands. Its not
something that confident in doing or could complete successful :(

My linux skills are junior at best. But I dont get into kernel hacking and debugging
However I do want to improve the linux user experience and got my photo of linus :)

Title:
  Touchpad of Toshiba CB30 not detected or working at all

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Hi

  I purchased a chromebook recently and ended up with a Toshiba CB30.
  The Chromebook wasnt cool enough until hacked it and loaded Ubuntu
  onto the device

  Much to my surprise the trackpad doesnt work at all.

  The internet made some suggestions like running a script which should fix it
  https://googledrive.com/host/0B0YvUuHHn3MndlNDbXhPRlB2eFE/cros-haswell-modules.sh

  After rebooting the device. No joy!
  Following the suggestions found here:
  https://wiki.ubuntu.com/DebuggingTouchpadDetection

  dmesg > ~/dmesg
  cat /proc/bus/input/devices > ~/devices

  Which exported the output into a file see attached. I notice no
  touchpad is being detected
