I just checked my dmesg: If ACPI is the problem, shouldn't dmesg show some "elan0651" device (although it does not bind any driver to it)?
So, if I cannot find any "elan" string in my dmesg, this should mean that the kernel does not find ANY i2c device with a similar hardware name, shouldn't it? => ACPI might not be the problem, rather the hardware identification of the linux kernel..? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1700657 Title: Touchpad not detected in Lenovo X1 Yoga / Yoga 720-15IKB To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1700657/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
