Hi, I installed my system (~amd64) around end december, with systemd as init. Touchscreen then worked fine out of the box. Around half february I updated the system and it stopped functioning. The kernel wasn't updated. Some xf86 drivers were, entire KDE, systemd and a lot of other packages as well. The device still exists, can read it out fine through evtest, cat /etc/input/event7, etc. Tried downgrading xf86-input-libinput, systemd, but doesn't help unfortunately. Think it has something to do with udev rules, but not sure. Bit at a loss here where to look. Most notably in the Xorg.0.log regarding the device is: [ 32.900] (II) config/udev: Adding input device ELAN Touchscreen (/dev/input/event7) [ 32.900] (**) ELAN Touchscreen: Applying InputClass "evdev touchscreen catchall" [ 32.901] (**) ELAN Touchscreen: Applying InputClass "libinput touchscreen catchall" [ 32.901] (II) Using input driver 'libinput' for 'ELAN Touchscreen' [ 32.901] (**) ELAN Touchscreen: always reports core events [ 32.901] (**) Option "Device" "/dev/input/event7" [ 32.901] (**) Option "_source" "server/udev" [ 32.901] (II) event7 - ELAN Touchscreen: is tagged by udev as: Touchscreen [ 32.901] (II) event7 - ELAN Touchscreen: device removed [ 32.920] (**) Option "config_info" "udev:/sys/devices/pci0000:00/0000:00:14.0/usb1/1-9/1-9:1.0/0003:04F3:21D5.0001/input/input9/event7" [ 32.920] (II) XINPUT: Adding extended input device "ELAN Touchscreen" (type: KEYBOARD, id 11) [ 32.920] (II) event7 - ELAN Touchscreen: is tagged by udev as: Touchscreen [ 32.920] (II) config/udev: Adding input device ELAN Touchscreen (/dev/input/mouse0) [ 32.920] (II) No input driver specified, ignoring this device. [ 32.920] (II) This device may have been added with another device file. Don't quite understand why it's ignoring it. /usr/share/X11/xorg.conf.d/40-libinput.conf, contains (amongst other parts): Section "InputClass" Identifier "libinput touchscreen catchall" MatchIsTouchscreen "on" MatchDevicePath "/dev/input/event*" Driver "libinput" EndSection Which looks fine to me. /usr/share/X11/xorg.conf.d/10-evdev.conf might also be able to claim it: Section "InputClass" Identifier "evdev touchscreen catchall" MatchIsTouchscreen "on" MatchDevicePath "/dev/input/event*" Driver "evdev" EndSection I tried wiping out /usr/share/X11/xorg.conf.d/*, but then entire keyboard/mouse etc. stopped working. Tried clearing out /lib64/udev/rules.d/ as well, but that didn't work out too swell either. Any pointers on where to look? The device itself seems to be fine, it's just the X drivers not attaching to it. Seems related to udev to me. flaptoppy / # udevadm info /dev/input/event7 P: /devices/pci0000:00/0000:00:14.0/usb1/1-9/1-9:1.0/0003:04F3:21D5.0001/input/input9/event7 N: input/event7 S: input/by-id/usb-ELAN_Touchscreen-event-if00 S: input/by-path/pci-0000:00:14.0-usb-0:9:1.0-event E: DEVLINKS=/dev/input/by-path/pci-0000:00:14.0-usb-0:9:1.0-event /dev/input/by-id/usb-ELAN_Touchscreen-event-if00 E: DEVNAME=/dev/input/event7 E: DEVPATH=/devices/pci0000:00/0000:00:14.0/usb1/1-9/1-9:1.0/0003:04F3:21D5.0001/input/input9/event7 E: ID_BUS=usb E: ID_INPUT=1 E: ID_INPUT_HEIGHT_MM=188 E: ID_INPUT_TOUCHSCREEN=1 E: ID_INPUT_WIDTH_MM=333 E: ID_MODEL=Touchscreen E: ID_MODEL_ENC=Touchscreen E: ID_MODEL_ID=21d5 E: ID_PATH=pci-0000:00:14.0-usb-0:9:1.0 E: ID_PATH_TAG=pci-0000_00_14_0-usb-0_9_1_0 E: ID_REVISION=1112 E: ID_SERIAL=ELAN_Touchscreen E: ID_TYPE=hid E: ID_USB_DRIVER=usbhid E: ID_USB_INTERFACES=:030000: E: ID_USB_INTERFACE_NUM=00 E: ID_VENDOR=ELAN E: ID_VENDOR_ENC=ELAN E: ID_VENDOR_ID=04f3 E: LIBINPUT_DEVICE_GROUP=3/4f3/21d5:usb-0000:00:14.0-9 E: MAJOR=13 E: MINOR=71 E: SUBSYSTEM=input E: USEC_INITIALIZED=2859904 Thanks in advance.

Created attachment 521362 [details] journal log (xz compressed plain/text format) Sorry about the additional lines. For some reason (still have to dive into it), NetworkManager keeps reconnecting on the USB-C dock ethernet. Works fine if I just run dhcpcd on the interface manually. Think something is triggering dbus events causing it.

Works again after enabling hid multitouch in the kernel. No clue why this previously wasn't necessary, but it apparently is required now.
