** Summary changed: - blackscreen when trying to resume from suspend + Kernel 4.10+ regression: blackscreen when trying to resume from suspend
** Description changed: When trying to resume after suspending my Lenovo Yoga 3 11, sometimes the screen remains black. The power LED switches from blinking to continuous light like it should but nothing else happens. The system does not react to anything. I tried to find something in the logs, but at least kern.log syslog and xorg.log never have any entries from this event. This problem appeared with Ubuntu 16.04 and 17.04 with Xorg and Wayland. I'm currently testing Kernel 4.8 from the mainline ppa because of this other suspend resume bug, that appeared only with 17.04: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1676912 + + Update: So far I did not encounter any issues with suspend/resume with + Kernel 4.8 and 4.9.
