Thanks How long does it take for an upstream fix?
I'm a long time C/C++ programmer (40+ years). I built kernels since the 0.99 days... So far, though, all I'm getting is black screens after loading the ram disk. Seems like the graphics drivers aren't loading. Normally the screen shows the Kubuntu graphic loading/splash screen at that point. I tried 4.13, 4.12, and 4.10 kernel builds. I'm going to give it one more try from the github repo (linus') -- 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/1700657 Title: Touchpad not detected in Lenovo X1 Yoga / Yoga 720-15IKB Status in Linux: Unknown Status in linux package in Ubuntu: Fix Committed Bug description: Touchpad is not automatically detected in 14.04, 16.04 or 17.04. I tried in live mode and after full installation. I was able to connect an external mouse and a bluetooth mouse and both worked.
