Description Jose 2016-09-30 15:33:43 UTC
Created attachment 126905 [details] Xorg.0.log with "lmr" option I'm running archlinux on an XPS 15 9550. This is the line from dmesg about the touchpad: input: DLL06E4:01 06CB:7A13 Touchpad as /devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-8/i2c-DLL06E4:01/0018:06CB:7A13.0001/input/input12 I just installed xf86-input-libinput-0.20.0 (with libinput-1.5.0) and wanted to test the new functionality to configure multi-finger tap mapping. The Touchpad stopped working when i enabled the "lmr" tap button map. I do this with this file: /etc/X11/xorg.conf.d/30-touchpad.conf Section "InputClass" Identifier "Touchpad" MatchIsTouchpad "on" Driver "libinput" Option "Tapping" "on" Option "TappingButtonMap" "lmr" Option "AccelSpeed" "1.0" Option "TappingDragLock" "on" EndSection When I restart X, the Touchpad does not seem to be working at all. No mouse movement, no clicks, nothing. I don't see any errors anywhere. I comment out the new option TappingButtonMap, restart X and the Touchpad works fine, defaulting to the usual lrm tab behaviour. I'll attach the Xorg log although I don't see anything weird in it. Actually, the diff between with and without the new option doesn't give us much: --- Xorg.0.log.defaultButtonMap 2016-09-30 10:12:37.160347552 -0500 +++ Xorg.0.log.lmrButtonMap 2016-09-30 10:12:53.247171749 -0500 @@ -13,7 +13,7 @@ rs: (--) probed, (**) from config file, (==) default setting, line, (!!) notice, (II) informational, ) error, (NI) not implemented, (??) unknown. -Log file: "/var/log/Xorg.0.log", Time: Fri Sep 30 09:56:01 2016 +Log file: "/var/log/Xorg.0.log", Time: Fri Sep 30 09:57:40 2016 Using config directory: "/etc/X11/xorg.conf.d" Using system config directory "/usr/share/X11/xorg.conf.d" No Layout section.

Comment 2 Peter Hutterer 2016-10-13 00:51:19 UTC
sorry for the delay, I was on holidays. I can't reproduce this here, the touchpad works fine with the options in place (expected, I did test this before pushing :) What is the output of xinput list-props <device name> ? does it show the properties enabled as expected? does xinput test-xi2 show any events for the touchpad? judging by the log, the touchpad should be just fine.

Same issue for me with HP ProBook 450 G2. Arch Linux linux 4.7.6-1 libinput 1.5.0-1 xf86-input-libinput 0.20.0-1 psmouse serio3: synaptics: Touchpad model: 1, fw: 7.5, id: 0x1e0b1, caps: 0xf00173/0x640000/0xa2400/0x0, board id: 2654, fw id: 1323623 input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio3/input/input18 /etc/X11/xorg.conf.d/30-touchpad.conf Section "InputClass" Identifier "touchpad" Driver "libinput" MatchIsTouchpad "on" Option "Tapping" "on" Option "TappingButtonMap" "lmr" EndSection `xinput test-xi2` doesn't show any events from touchpad.

Created attachment 127278 [details] xinput list-props (XPS 15 9550) 'xinput test-xi2' doesn't report any events from the touchpad and neither does xev.
Comment 6 Jose 2016-10-13 21:02:23 UTC
As I mentioned before the touchpad works fine when the "TappingButtonMap" line is commented out. These are the differences in the output of `xinput list-props` between those two cases: --- xinput-list-props-default.log 2016-10-13 14:51:35.859922992 -0600 +++ xinput-list-props.log 2016-10-13 14:45:30.084367459 -0600 - libinput Tapping Button Mapping Enabled (305): 1, 0 + libinput Tapping Button Mapping Enabled (305): 0, 1 - libinput Send Events Mode Enabled (263): 0, 0 + libinput Send Events Mode Enabled (263): 1, 0
Comment 7 Peter Hutterer 2016-10-13 21:42:00 UTC
(In reply to Jose from comment #6) > - libinput Send Events Mode Enabled (263): 0, 0 > + libinput Send Events Mode Enabled (263): 1, 0 where does this come from? this is the libinput equivalent to "device is disabled now" which explains why it's dead. but why is this being set? could it be some desktop environment interfering here?
Comment 8 Jose 2016-10-14 03:01:58 UTC
I started X without a desktop environment, using startx (it gave me a black screen with 3 xterms), and the mousepad was still not working. Just in case I'll mention that the display manager I use is lightdm and the desktop environment is cinnamon. The mousepad is already not working inside lightdm, before I log.
Comment 9 Peter Hutterer 2016-10-14 03:44:39 UTC
found it, it was a typo. and it was my DE that was 'interfering', apparently it enabled the device unconditionally, so the obvious error in the patch got papered over. commit 6318ac420b644c7f7a6f2c8e47a64238a4afebeb Author: Peter Hutterer <email@example.com> Date: Fri Oct 14 13:34:56 2016 +1000 Fix tap button map option handling
Comment 10 Jose 2016-10-17 19:30:09 UTC
Peter: I was gonna test your fix and confirm it works in my system but I can't find it anywhere. It's not in the git repo.

Comment 12 Jose 2016-10-18 02:08:50 UTC
Thanks for the link. Like the dummy I am I was looking for it in libinput's git repo. Anyway, I can confirm that the patch fixes the issue on my end. Thanks.
