Middle mouse (wheel-click) button stopped working after upgrade to 16.04

[Guntbert Reiter]

The issue looks exactly like #1581088 but I've been asked to file a separate report.

xev registers buttons 1(left),3(right), 4,5 (scroll wheel), 8,9 (back, forward), but NOT 2

I've already tested with 4.6.0-040600rc7-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc7-wily/

I'll be happy to provide additional info as needed.

Christopher, thanks for doing that research for me. I upgraded the BIOS (easy enough :-))

No improvement - the middle button is still not recognized at all.

The requested output (no idea if the "invalid entry length" lines are important)

3707
Invalid entry length (16). Fixed up to 11.

Invalid entry length (16). Fixed up to 11.

Guntbert Reiter, could you please test the latest mainline kernel (4.7-rc2) and advise to the results?

[Guntbert Reiter (guntbert)]

Just now I am running under

Linux big 4.7.0-040700rc2-generic #201606051831 SMP Sun Jun 5 22:33:44 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

The results are the same - all other buttons (1,3,4,5,8,9) work, the middle button works never.

[penalvch (penalvch)]

Guntbert Reiter, to clarify, what was the most recent release of Ubuntu this last worked in?

[Guntbert Reiter (guntbert)]

The last Ubuntu release where it worked was 15.10 .
But I am not certain if it stopped working immediately after the upgrade - it took me some time to realize it was not only me not pressing the button properly :-)

[penalvch (penalvch)]

Guntbert Reiter, the next step is to fully commit bisect from kernel 4.2 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

Also, the kernel release names are irrelevant for the purposes of bisecting.

After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed.

Thank you for your understanding.

blush :-/

After not finding a kernel where it worked I finally tried on another computer, running Windows - and it didn't work either.

So it looks like a hardware issue that possibly occured at about the same time as the update.

Sorry to have wasted your time.

I had the same problem when updating the BIOS in my laptop (ASUS G501VW).

Didn't get middle button, nor back/forward.

For me, the problem was that when updating the BIOS Fast Boot was set to ON automatically, putting it back to OFF resolved the issue for me.

MS Sculp Mouse wheel scroll suddenly stop working for me on 16.04.
On Windows it's okay.
Very unpleasant experience for web surfing now..
Please fix it.
