Hi Kai-Heng Feng, I have a laptop with the same problem. It's a SCHNEIDER SCL142ALM.
I have compiled the ubuntu kernel modifying the "i2c_hid_dmi_desc_override_table" to add: { .ident = "SCHNEIDER SCL142ALM", .matches = { DMI_EXACT_MATCH(DMI_SYS_VENDOR, "SCHNEIDER"), DMI_EXACT_MATCH(DMI_PRODUCT_NAME, "SCL142ALM"), }, .driver_data = (void *)&sipodev_desc }, And it's working fine. Probably I could ask to include it in the next kernel version, but I think that it's not a good option to modify the kernel for every new vendor and model that decides to use this device. It would be possible to add some parameter in the bootargs like for example psmouse.proto=sipodev and then use the i2c-hid-dmi-quirks? In the meanwhile, please can you add the SCHNEIDER SCL142ALM to the override list? Than you. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1825718 Title: Touchpad not detecting in Linux Status in linux package in Ubuntu: Confirmed Bug description: This issue was observed in laptop -"iBall-Aer3" which has a touch-pad with integrated fingerprint scanner.
