Here you go — copy and paste this: I have the same issue on an **Acer Swift SFX14-61G** with the **PIXA4812:00 093A:4812** touchpad controller.
Running Ubuntu 26.04, kernel `7.0.0-29-generic`, libinput `1.31.1`. `dmesg` shows the touchpad is detected correctly at boot, and `libinput list-devices` also sees it properly (size 136x83mm). Clicks work fine (`POINTER_BUTTON` events register correctly in `libinput debug-events`), but all pointer motion is discarded with repeated: ``` libinput error: event11 - PIXA4812:00 093A:4812 Touchpad: kernel bug: Touch jump detected and discarded. ``` Also noticed in `dmesg` that this touchpad appears to enumerate on two separate I2C buses (`i2c-0` and `i2c-2`), which may be related. Tried a full system update (`apt full-upgrade`) and BIOS update to the latest available (v1.09) — neither resolved it. Currently unusable without an external mouse. --- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2143915 Title: PIXA4812:00 093A:4812 (Acer Swift SFX14-73G): repeated touch jump causes severe cursor stuttering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2143915/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
