Touchpad not detected

[Preston]

I have an ASUS ZenBook UX301L. The touchpad used to work before upgrading.

WORKAROUND: External mice work fine.

I upgraded my BIOS to 209 - still no dice - why would upgrading BIOS help the trackpad though? The trackpad works in windows.

Anywho, as for 'what happened' - I really can't say - as much as I'd love to. I know that's frustrating and unhelpful, but I did like.. 100 things in order to get chrome to like my touchscreen, including reinstalling the kernel.

[penalvch (penalvch)]

Preston, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

4.1-rc2-vivid did not work.

[Preston (theprecognition+launchpad)]

4.0-vivid did not work.

[Preston (theprecognition+launchpad)]

3.19.8 did not work.

[Preston (theprecognition+launchpad)]

Skipped a few

Ubuntu 3.16.0.29-generic - Trackpad works at login screen, but stops once I log in. The trackpad is detected, however.

[Preston (theprecognition+launchpad)]

Ubuntu 3.16.0-34-generic - Track pad doesn't work at all - not detected either.

[Preston (theprecognition+launchpad)]

Going back,

Ubuntu 3.16.0-30-generic Track Pad works at login screen. Stops once I login in.

Only 31,32,and 33 to go. woo

[Preston (theprecognition+launchpad)]

Ubuntu 3.16.0-31-generic Track Pad works at login screen. Stops once I login in.

[Preston (theprecognition+launchpad)]

Ubuntu 3.16.0-33-generic Track Pad works at login screen. Stops once I login in.

Looks like I don't have 32.

but that's ok, looks like the bug was introduced in 3.16.0.34-generic

now to try the upstream version

[Preston (theprecognition+launchpad)]

Upstream 3.16.7 doesn't detect the track pad.

[Preston (theprecognition+launchpad)]

Ustream 3.16.0 didn't even make it to the login screen

[Preston (theprecognition+launchpad)]

Upstream 3.16.1 didn't make it to the login screen either.

[Preston (theprecognition+launchpad)]

Upstream 3.16.6 doesn't detect the trackpad

[Preston (theprecognition+launchpad)]

I didn't find any upstream kernels where the trackpad was detected.

I did find the last Ubuntu kernel where the trackpad worked, though.

What's the average timeline for fixing bugs like this one?
