Description Andy Lutomirski 2016-01-07 20:01:32 UTC 
On kernel-4.3.3-300.fc23.x86_64, my Dell XPS 13 9350's trackpad doesn't work reliably (it fails shortly after boot and doesn't come back).  The issue is fixed upstream by this patch, which is unfortunately not tagged for -stable.

Comment 1 Josh Boyer 2016-01-07 20:06:51 UTC 
Benjamin, should this be backported?
Comment 2 Benjamin Tissoires 2016-01-08 08:22:05 UTC 
I think it's fine. Iĺl let Greg know also upstream.
Comment 3 Josh Boyer 2016-01-08 13:12:31 UTC 
Patch added in Fedora git.  Thanks!
Comment 4 Fedora Update System 2016-01-15 19:25:32 UTC 
kernel-4.3.3-301.fc23 has been submitted as an update to Fedora 23. https://bodhi.fedoraproject.org/updates/FEDORA-2016-26e19f042a
Comment 5 John Loring 2016-01-15 23:07:22 UTC 
Said problem also occurs on Dell XPS 15 9550. Although, bug filer states trackpad works at the very beginning. On mine, trackpad does not work at all when booting into OS with said kernel.

When will I be able to update my kernel with 4.3.3-301, with fix as indicated by Comment 4?
Comment 6 Josh Boyer 2016-01-15 23:34:32 UTC 
It was submitted to updates-testing today.  It should be in updates-testing repos on the mirrors within the next few days.

Comment 12 John Loring 2016-01-22 13:43:18 UTC 
I thought version 301 fixed the trackpad bug. What is version 303 supposed to fix?
Comment 13 Josh Boyer 2016-01-22 13:51:08 UTC 
There were some bodhi issues that caused some update and bugzilla hiccups.  The bug is fixed in -301 _and_ -303.  -303 just has additional unrelated fixes.
Comment 14 John Loring 2016-01-22 13:55:38 UTC 
Thanks. The reason I ask is because I have another bug report that has been filed (for a system hang issue). I am assuming that a kernel update is pending for that bug fix as well. Thanks again.
Comment 15 Josh Boyer 2016-01-24 03:30:52 UTC 
We've had several reports of Acer Touchpads breaking in the -301 kernel, which includes this patch.  See the bodhi comments on this update.

Have there been any reported regressions or additional fixes upstream?  I'm going to have to drop this patch with the 4.3.4 kernel if we can't get these fixed.
Comment 16 Benjamin Tissoires 2016-01-24 08:36:38 UTC 
Hmm, I can't seem to find those comments you are mentioning. Josh, are you sure this patch breaks the Acer systems and not the other ones regarding the designware controller?
Comment 17 Isaque Galdino 2016-01-24 13:26:25 UTC 
So, this is the guilt one - this bloody Dell :) ! My acer touchpad was working before, until kernel-4.3.3-300, now it doesn't work with the new one anymore:

$ uname -a
Linux xxxx.xxxxxxx 4.3.3-301.fc23.x86_64 #1 SMP Fri Jan 15 14:03:17 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Thanks.

Unfortunately, I haven't seen an actual bug opened and the comments are sparse.
Comment 19 John Loring 2016-01-24 23:53:33 UTC 
In response to comment #15, my trackpad has worked ever since the bug fix. Please don't drop the patch with kernel 4.3.4.

It's a tough call.  It fixes the touchpad to work for the first time ever on your new machine, but it appears (?) to cause regressions on other machines.  Regressions tend to outweigh new support.

I haven't dropped it yet, so there is still time to fix it.
Comment 21 Andy Lutomirski 2016-01-25 01:30:50 UTC 
Benjamin, what are the other designware patches you're looking at?  Would it make sense to do a scratch build that one of the affected Acer users could test to help narrow it down?
Comment 22 Benjamin Tissoires 2016-01-25 09:36:33 UTC 
I did not remembered I already had to fix the Elan panels in the 4.5 kernel.

Josh, could you add
https://git.kernel.org/cgit/linux/kernel/git/jikos/hid.git/commit/?h=for-4.5/multitouch&id=73e7d63efb4d774883a338997943bfa59e127085

To the fedora kernel, with some luck, this will solve the Acer Elan touchpads problems.

Andy, I don't think this is designware related. hid-multitouch binds properly for these panels. The commit I mentioned above is more likely to fix the issues here.

Gladly.  I'll get it into the 4.3.4 build.

Comment 27 John Loring 2016-01-25 18:27:41 UTC 
Is the trackpad fix persistent in the 4.3.4-300 kernel update for F23?
Comment 28 Josh Boyer 2016-01-25 18:28:34 UTC 
Both the XPS fix and the patch Benjamin highlighted are in 4.3.4-300/200.  Testing would be appreciated.
Comment 29 John Loring 2016-01-25 21:55:25 UTC 
I appreciate your concern for testing. And, I would like to help by testing the update. However, on the same machine I am dealing with a screen brightness issue that if not fixed, very noticeably irritates my eyes. I will say that if I can get the opportunity to test the kernel update, I will do exactly that. I know you work really hard to deliver, and it's a team effort. I will participate in helping to deliver success if I get the opportunity. Much thanks.

In the meantime, do you know if any of the participants in this website (Red Hat Bugzilla) can generate a fix for the dim display/brighten display buttons on my keyboard to work?

It would probably make sense to file a separate bug for that.  Including the exact model of your laptop would help, too, as would whatever messages, if any, end up in the kernel log (type 'dmesg | tail') when you press the brightness buttons.

In general, the brightness buttons should work on all laptops.  If they don't, it's a bug.

I am in the middle of filing a bug report for the display brightness problem, but the bug report tool is requiring me to select a "Component" for the bug, and I do not know what component to select. Which component should I select for this particular bug (display brightness not working on keyboard)? Thanks.

I was just about to tell you "never mind, I just used 'kernel'", and then I saw your reply. Nonetheless, I believe I filed an accurate and helpful bug on that. Thanks for your assistance.
