Created attachment 905617 [details] Xorg.0.log Description of problem: thinkpad Yoga S1 has a wacom digitizer which was correctly detected on a vanilla F20 install. Updating to current makes it disappear. It doesnt show anymore in gnome, xinput nor xsetwacom, altough is detected by xorg and libwacom. Heres xinput output, un-updated F20: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ELAN Touchscreen id=9 [slave pointer (2)] ⎜ ↳ Wacom ISDv4 EC Pen stylus id=11 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)] ⎜ ↳ TPPS/2 IBM TrackPoint id=14 [slave pointer (2)] ⎜ ↳ Wacom ISDv4 EC Pen eraser id=16 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Integrated Camera id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=15 [slave keyboard (3)] and up-to-date: $ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ELAN Touchscreen id=9 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)] ⎜ ↳ TPPS/2 IBM TrackPoint id=13 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Integrated Camera id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=14 [slave keyboard (3)] in both cases it is detected by libwacom & xorg though: $ libwacom-list-local-devices [Device] Name=Wacom ISDv4 EC DeviceMatch=usb:056a:00ec; Class=ISDV4 Width=0 Height=0 IntegratedIn=Display;System; Styli=0xfffff;0xffffe; [Features] Reversible=false Stylus=true Ring=false Ring2=false Touch=true StatusLEDs= NumStrips=0 Buttons=0 Version-Release number of selected component (if applicable): $ rpm -qa | grep wacom libwacom-0.8-2.fc20.x86_64 xorg-x11-drv-wacom-0.23.0-5.fc20.x86
Can you attach a log from the updated xorg? I can't think of a reason why xinput wouldn't show the device if it's been added by the server (though if xinput can't see it then gnome and xsetwacom don't either, so at least that part is consistent).
That was suprisingly helpful :) I thought that submitted log was the latest, but made me discover that somewhere along the line /var/log/Xorg.0.log got deprecated. So the latest log from journald obviously points to the problem : ------------------ juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (II) Using input driver 'synaptics' for 'Wacom ISDv4 EC Pen' juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (**) Wacom ISDv4 EC Pen: always reports core events juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (**) Option "Device" "/dev/input/event13" juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (EE) synaptics: Wacom ISDv4 EC Pen: Synaptics driver unable to detect protocol juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (EE) PreInit returned 11 for "Wacom ISDv4 EC Pen" juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (II) UnloadModule: "synaptics" juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (II) config/udev: Adding input device Wacom ISDv4 EC Pen (/dev/input/mouse2) juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (II) No input driver specified, ignoring this device. juin 11 11:18:52 yogi gdm-Xorg-:0[4785]: (II) This device may have been added with another device file. ---------------- so synaptics driver claims my wacom. I've got a synaptics.conf in xorg.conf.d (which was happily working since day 1 in harmony with wacom though) Sure enough, taking this out make the wacom come back. thats the relevant part of synaptics.conf: Section "InputClass" Identifier "Touchpad" MatchIsTouchpad "yes" Driver "synaptics" Option "MinSpeed" "0.5" [...] So the bug is that this started matching also the wacom, nuking its initialization. Im 100% sure that it was working without conflict few updates ago.
oh, and the workaround is to replace in synaptics.conf : Driver "synaptics" with MatchDriver "synaptics"
closing this as NOTABUG, local configuration caused the issue. I'd be interesting to see the udevadm info --export-db output for the device, if it has ID_INPUT_TOUCHPAD set then that would cause the MatchIsTouchpad line to trigger. Unfortunately the simple matching isn't always that accurate, with your change to MatchDriver you're now letting the driver assignment be done by the match rules we ship with the packages, and then you just add your configuration on top of that. Which is how you should do it anyway :)
yep, it's much saner to match the driver than to enforce it. Unfortunately, the .conf I've used is all over the net in several synaptics tutos. Anyway, hope that this report wil shed the light if other people trigger this.
Created attachment 908620 [details] udevadm info db ID_INPUT_TOUCHPAD and _TABLET are both set for wacom.
