I have dual boot Windows 10 64bit and Ubuntu Mate 16.04 LTS.

A couple weeks ago in January 2017, after I did system update both for Windows and maybe for Ubuntu too (not really remember) my touchpad suddenly acting weird.

I Already ask this question in detail here: https://plus.google.com/113527255489567722959/posts/BgQY9dFybJ6

From my testing, the touchpad is working normal if I use Windows bootable USB flashdrive, so my focus is on the bootloader now.

I use Grub 2.02 beta2, and already edit the file part to below:

GRUB_CMDLINE_LINUX_DEFAULT="http://i8042.reset quiet splash"

Yes it make positive result, the touchpad now still working after suspend/sleep, except it sleep too long. But still not reliable, often I need to restart the laptop or shutdown many times to make the touchpad & trackpoint work.

Please help, what must I do to fix the problem. How to fix the bootloader?

Thanks for answering.

  • I would say http://i8042.reset does nothing. How did you came up with that? – user589808 Feb 16 '17 at 17:11
  • Sorry, i didn't notice and no idea how that can happen. I copy my question from another forum to this page – ariefcfa Feb 18 '17 at 14:01

Problem solved.

I edit the grub part as mentioned here:

Touchpad is not recognized

and here

Touchpad under 16.04 not working

And get positive result, the touchpad and trackpoint is detected and working more often after system boot. If it not, i found the workaround it is by put the computer to sleep, and repeat as suggested here: https://www.sevenforums.com/hardware-devices/329195-touchpad-trackpad-inoperable-after-sleep-post3270196.html?s=35750b7293ab81e52bcb45428de94cec#post3270196

Problem solved :)). Thanks.
