apport information ** Tags added: apport-collected noble wayland-session
** Description changed: When scrolling anywhere using 2 fingers the scroll bounces back if fingers are lifted up from touchpad. Soft finger point muscles have some flex to them and I strongly believe this causes the scroll bounce back. Easily repeated to both directions. In bounce scroll rapidly moves to the opposite direction of where user wanted to scroll when lifting up fingers. Attached is log file evtest_event5.log from single scroll where there was bounce at lifting fingers. Hardware details: xinput --list WARNING: running xinput against an Xwayland server. See the xinput man page for details. ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ xwayland-pointer:16 id=6 [slave pointer (2)] ⎜ ↳ xwayland-relative-pointer:16 id=7 [slave pointer (2)] ⎜ ↳ xwayland-pointer-gestures:16 id=8 [slave pointer (2)] ⎜ ↳ xwayland-touch:16 id=10 [slave pointer (2)] ⎜ ↳ xwayland-tablet stylus:16 id=11 [slave pointer (2)] ⎜ ↳ xwayland-tablet eraser:16 id=12 [slave pointer (2)] ⎜ ↳ xwayland-tablet cursor:16 id=13 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ xwayland-keyboard:16 id=9 [slave keyboard (3)] lshw *-input:0 product: Sleep Button physical id: 2 logical name: input0 logical name: /dev/input/event0 capabilities: platform *-input:1 product: Lid Switch physical id: 3 logical name: input1 logical name: /dev/input/event1 capabilities: platform *-input:2 product: Intel HID events physical id: 4 logical name: input17 logical name: /dev/input/event9 capabilities: platform *-input:3 product: ThinkPad Extra Buttons physical id: 5 logical name: input18 logical name: /dev/input/event10 capabilities: platform *-input:4 product: SYNA8007:00 06CB:CD8C Mouse physical id: 6 logical name: input19 logical name: /dev/input/event4 logical name: /dev/input/mouse0 capabilities: i2c *-input:5 product: Power Button physical id: 7 logical name: input2 logical name: /dev/input/event2 capabilities: platform *-input:6 product: SYNA8007:00 06CB:CD8C Touchpad physical id: 8 logical name: input20 logical name: /dev/input/event5 logical name: /dev/input/mouse1 capabilities: i2c *-input:7 product: Video Bus physical id: 9 logical name: input22 logical name: /dev/input/event11 capabilities: platform *-input:8 product: sof-hda-dsp Mic physical id: a logical name: input23 logical name: /dev/input/event12 *-input:9 product: sof-hda-dsp Headphone physical id: b logical name: input24 logical name: /dev/input/event13 *-input:10 product: sof-hda-dsp HDMI/DP,pcm=3 physical id: c logical name: input25 logical name: /dev/input/event14 *-input:11 product: sof-hda-dsp HDMI/DP,pcm=4 physical id: d logical name: input26 logical name: /dev/input/event15 *-input:12 product: sof-hda-dsp HDMI/DP,pcm=5 physical id: e logical name: input27 logical name: /dev/input/event16 *-input:13 product: AT Translated Set 2 keyboard physical id: f logical name: input3 logical name: /dev/input/event3 logical name: input3::capslock logical name: input3::numlock logical name: input3::scrolllock capabilities: i8042 *-input:14 product: TPPS/2 ALPS TrackPoint physical id: 10 logical name: input5 logical name: /dev/input/event6 logical name: /dev/input/mouse2 capabilities: i8042 + --- + ProblemType: Bug + ApportVersion: 2.28.1-0ubuntu2 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/seq: think 2152 F.... pipewire + /dev/snd/controlC0: think 2152 F.... pipewire + think 2156 F.... wireplumber + CRDA: N/A + CasperMD5CheckResult: pass + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 24.04 + InstallationDate: Installed on 2024-04-29 (1 days ago) + InstallationMedia: Ubuntu 24.04 LTS "Noble Numbat" -
