http://bugzilla.opensuse.org/show_bug.cgi?id=1043653 http://bugzilla.opensuse.org/show_bug.cgi?id=1043653#c6 --- Comment #6 from Jeff Piatt --- I tried blacklisting hid-multitouch. The result: touchpad is non-functional. Sensitivity/pressure settings DO show up in the touchpad GUI settings as enabled. Running xinput shows only the SynPS/2 Touchpad (not the DLL... one), and after resume from suspend shows neither. So basically, the result seems the same as when I ignore the DLL... touchpad. -- You are receiving this mail because: You are on the CC list for the bug.

Very little touchpad adjustment available in libinput, as far as I can tell, and nothing having to do with sensitivity and pressure. So it's back to square one - a stiff physical click mechanism, and no possibility of adjusting a hypersensitive tap-to-click. -- You are receiving this mail because: You are on the CC list for the bug.

But because there is no ABS_MT_PRESSURE data or events coming out of my hardware, the seemingly good advice in that link is not applicable. Perhaps it is a Dell problem? Their forums are a ghost town, and they're more concerned with marketing than fixing things, so there's no hope there either. Maybe it's time to sell my "top of the line" linux laptop. Honestly I don't get it... -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1043653 http://bugzilla.opensuse.org/show_bug.cgi?id=1043653#c12 --- Comment #12 from Takashi Iwai --- Hrm, it's strange, indeed. Usually the hid-multitouch reports the whole events at once in mt_complete_slot(), and ABS_MT_PRESSURE is included there, at least. It might be that a wrong driver is bound in the end. In anyway, reporting to the upstream would be helpful, as this doesn't seem like an openSUSE-specific issue. Also, it'd be better to specify exactly which XPS 13 model. Is it 9360? -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1043653 http://bugzilla.opensuse.org/show_bug.cgi?id=1043653#c14 --- Comment #14 from Jeff Piatt --- I'm *relatively* ignorant about computers and linux, so before I proceed I'd like to know whether this could be a hardware issue. Is it possible that there is a problem in the way Dell has integrated the touchpad into the 9360 XPS 13, and that this is the root cause of the necessary events (ABS_PRESSURE, ABS_MT_PRESSURE, ABS_TOOL_WIDTH) not being generated? And if so, is it also therefore possible that no amount of work on the Linux end (Opensuse or otherwise, or upstream) would be able to fix the issue? I want to know the answers to each of these questions, because I've raised the issue with Dell, and just now have started getting some response. Knowing such answers, and maybe even some compelling ways to convey the issue technically to them, might help me convince them that the solution lies only with Dell (if indeed that is the case). I've already shared with them all the information I've posted in this bug report, but sometimes they seem slow to engage with details. Maybe they don't have the resources for linux-related problems. If not, that is if this is an issue that can be solved here or upstream, then I am happy to continue filing another bug. Although I need to know precisely what "upstream" means. Where would such a bug be filed? Thanks for advice on how to proceed! -- You are receiving this mail because: You are on the CC list for the bug.

They don't seem concerned that their flagship Linux laptop can't generate touchpad pressure data (something any old cheap laptop can do). I give up on them. But I'd still like to know the answer to my above question: Is it possible this could be a hardware issue, or something related to the way Dell has implemented the touchpad into the 9360 XPS 13, and that this is the root cause of the necessary events (ABS_PRESSURE, ABS_MT_PRESSURE, ABS_TOOL_WIDTH) not being generated? And if so, doesn't that make it likely that no amount of work on the Linux end (Opensuse or otherwise, or upstream) would be able to fix the issue? If the answer is that this scenario is possible, then I don't think this is worth pursuing. If this scenario is possible, then I'm pretty convinced that no one has ever gotten any pressure/sensitivity settings to work on the 9360 XPS 13, in any distribution or even in Windows for that matter. And if that's the case then there's no use going on a wild goose chase. So, bump to this question..! -- You are receiving this mail because: You are on the CC list for the bug.
