Package: libinput10 Version: 1.15.1-1 Severity: important Hi Timo,
I encounter a very nasty regression with the latest update of libinput. The touchpad in my X220 no longer works reliably. When I swipe over the touchpad area, sometimes the cursor simply stops moving. This happens sporadically. Downgrading to 1.14.3-1 fixes the issue immediately. libinput list-devices output (removed a few unrelated entries) Device: SynPS/2 Synaptics TouchPad Kernel: /dev/input/event5 Group: 8 Seat: seat0, default Size: 74x43mm Capabilities: pointer gesture Tap-to-click: disabled Tap-and-drag: enabled Tap drag lock: disabled Left-handed: disabled Nat.scrolling: disabled Middle emulation: disabled Calibration: n/a Scroll methods: *two-finger edge Click methods: *button-areas clickfinger Disable-w-typing: enabled Accel profiles: none Rotation: n/a Device: TPPS/2 IBM TrackPoint Kernel: /dev/input/event6 Group: 9 Seat: seat0, default Capabilities: pointer Tap-to-click: n/a Tap-and-drag: n/a Tap drag lock: n/a Left-handed: disabled Nat.scrolling: disabled Middle emulation: disabled Calibration: n/a Scroll methods: *button Click methods: none Disable-w-typing: n/a Accel profiles: flat *adaptive Rotation: n/a Device: ThinkPad Extra Buttons Kernel: /dev/input/event7 Group: 10 Seat: seat0, default Capabilities: keyboard switch Tap-to-click: n/a Tap-and-drag: n/a Tap drag lock: n/a Left-handed: n/a Nat.scrolling: n/a Middle emulation: n/a Calibration: n/a Scroll methods: none Click methods: none Disable-w-typing: n/a Accel profiles: n/a Rotation: n/a (This output from libinput 1.14.3) -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.4.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libinput10 depends on: ii libc6 2.29-10 ii libevdev2 1.8.0+dfsg-2 hi libinput-bin 1.14.3-1 ii libmtdev1 1.1.5-1.1 ii libudev1 244.2-1 ii libwacom2 1.1-2 libinput10 recommends no packages. libinput10 suggests no packages. -- no debconf information
