Arch Linux

I am using a 2014 model XPS 13, fyi. It seems only certain people on certain models are experiencing this issue

Weird, updating again to 4.11.2 after rolling back to 4.10 seems to have rectified the issue. I don't know why installing the kernel for a third time solved the issue, but it appears to be working now.

Actually, I take that back. I hadn't rebooted, and the issue is still present. I am reverting to 4.10.x for the time being

The issue is actually that with the new kernel left/right clicking is completely broken. No left and right click events are registered. The reason that it gave the above symptoms was that it was treating "click and drag" as two finger scrolling, since the click aspect wasn't being registered.

Are your symptoms like on this post or something different: https://bbs.archlinux.org/viewtopic.php?pid=1713984 ? If they are, then we probably have the same bug. Pressing the touchpad (clickpad) doesn't work, but tapping works, if enabled of course.

Yes that is the exact issue that I have

Clicking seems to be working again with 4.11.3. Requesting closure because the problem appears to have worked itself out.

Nevermind. While everything was working fine for about an hour, for some reason the left/right click stopped working again and now won't come back even through a reboot. I swear it was working though for an hour or so. I don't know what is happening.

I had it also working at some point with 4.11, when I tried to demostrate the problem, but after that it hasn't worked.

I attached here lsmod and libinput-list-devices logs for both 4.11.3 and 4.10.9. The touchpad is recognized differently on 4.11 and there is one new module in lsmod output (rmi_core). These logs are from Dell XPS13 model 9333 (the one with Haswell processor).

This is the bug report over on freedesktop that the HID guys are looking into: https://bugs.freedesktop.org/show_bug.cgi?id=101179

Interesting enough he said "IIRC, 4.11 on these laptops should still be using hid-multitouch (like in v4.10) as we had some troubles with hid-rmi.", and since you reported a new module 'rmi_core', perhaps this is the issue. Maybe we aren't using hid-multitouch like we should be

I can confirm that on our touchpads with 4.11.x lsmod reports that we are making use of rmi_core/hid_rmi, which according to the folks over on freedesktop is known to be buggy. On kernels prior to 4.11.x, hid_multitouch was used.

I'm guessing that this is the root of our problem.

This doesn't seem to be a problem for me anymore. My laptop has worked fine with the last couple of kernel releases
