** Description changed: + https://errors.ubuntu.com/problem/a9ace2e3301009e3a5344f8dac4e56fc4c23b1b8 + + --- + I'm testing Ubuntu 17.10 installed on Lenovo PC (with Intel Core i5-6500 CPU and Intel HD Graphics 530 (skylake GT2). Session is crashing (login screen is displayed again) every time I change the monitor Input (e.g. from DP to HDMI) or switching off the monitor. It is happening since some updated from beginning of September were installed. Same situation is for both session types, default Wayland and also for X.org. Tested also with Live USB, same behaviour.
