Touchpad incorrectly detected as PS/2 mouse in 'HP Pavillion 340G1' after Ubuntu 12.04 upgrade to 14.04.

[Daniel Ojeda]

I'm currently using Linux 4.2.0-38-generic Kernel.

I adjunct in a .txt the outputs for
-dmesg
-cat /proc/bus/input/devices

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Daniel Ojeda (donbalon4)]

I tried to test the kernel that you mentioned, but unfortunately, I get an error (can't create /sys/kernel/uevent_helper), so I couldn't start the system with that kernel.

[penalvch (penalvch)]

Daniel Ojeda, to see if this is already resolved, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[Daniel Ojeda (donbalon4)]

sure, but I will be able to test this weekend.
Regards

[Daniel Ojeda (donbalon4)]

I tested today the cd image and the touchpad was recognized correctly. All worked fine with the live cd.
Thank you!

[penalvch (penalvch)]

Daniel Ojeda, do you need a backport to a release prior to Yakkety? If not, please feel free to close this as Status Invalid.

[Daniel Ojeda (donbalon4)]

yes, I will appreciate a backport to Trusty Tahr :)

[penalvch (penalvch)]

Daniel Ojeda, one may use the xenial enablement stack as outlined in https://wiki.ubuntu.com/Kernel/LTSEnablementStack . Could you please advise if it is reproducible with it?

[Daniel Ojeda (donbalon4)]

I tried that, but it didn't work :c

[penalvch (penalvch)]

Daniel Ojeda, to help narrow down where the fix is available, could you please test the latest mainline kernel (4.8-rc3) and advise to the results?

[Daniel Ojeda (donbalon4)]

I get this when I boot with that kernel: can't create /sys/kernel/uevent_helper

[penalvch (penalvch)]

Daniel Ojeda, would 4.8-rc7 provide a testable environment?

[Daniel Ojeda (donbalon4)]

I get the same message when I boot with that kernel

[penalvch (penalvch)]

Daniel Ojeda, I am closing this report because the bug has been fixed in the latest development version of Ubuntu.

This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention.
