Hi, I also have the 0000:00:1f.4 and the nfc model (20KG-S03900) and I don’t have this issue. Even my trackpoint now survives resumes/suspends since using 4.19.1 and upgrading all firmware (using windows) (touchpad/trackpoint/bios/thunderbolt).
I can just repeat the steps, which where necessary for me on ubuntu 18.04.1: 1. Removing the blacklisting of i2c_i801 in /etc/modprobe but this is now default in ubuntu 18.04 (see: https://bugs.launchpad.net/hwe-next/+bug/1786574 ) 2. Installing a newer kernel from mainline ppa: currently using 4.19.2 3. Using libinuput 1.12.1-1 and xserver-xorg-input-libinput with: sudo dpkg -i libinput10_1.12.1-1_amd64.deb libinput-bin_1.12.1-1_amd64.deb xserver-xorg-input-libinput_0.28.1-1_amd64.deb the files are available here: https://launchpad.net/ubuntu/+source/xserver-xorg-input-libinput and https://launchpad.net/ubuntu/+source/libinput (4.) I also use the padoka stable mesa ppa. Maybe it would help if we identify the differences between our devices. Have you tested if a second suspend/resume cycle revives the touchpad? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791427 Title: Touchpad and/or trackpoint stop working after S3 suspend on Lenovo X1 Carbon 6th To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791427/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
