That's strange then, maybe the old driver is still builtin in https://people.canonical.com/~khfeng/lp1787775/.
Kai is waiting for the driver to be accepted by Linux's maintainers before applying it to Ubuntu's kernel. If you want to get the touchpad working beforehand on your Yoga 530-14ARR, I suggest installing Ubuntu 18.04, this kernel: https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19.9/ Then the i2c-amd-mp2 driver in DKMS version with the following commands: sudo apt install build-essential dkms git clone https://github.com/Syniurge/i2c-amd-mp2.git cd i2c-amd-mp2 sudo ./dkms-install.sh Reboot and the touchpad and touchscreen should work. -- 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/1787775 Title: touchpad not working on lenovo yoga 530 Status in linux package in Ubuntu: Confirmed Bug description: The touchpad is not working and does not show up in cat /proc/bus/input/devices on multiple kernels.
