2019-01-24 11:22:12 Alex description I have been experiencing an issue only since a week or so, which I have reportedly also heard from a colleague of mine (2018 Dell XPS 13) since much longer. My hardware is a Lenovo Thinkpad L480 with i5-8250u. When using stock ubuntu 18.04.1, sometimes and sporadically (1 out of 3 or so) after resuming from suspend, the screen would not be locked and flicker, switching between a fully black screen and the previously (before going to standby) displayed content, which I regard as a security issue. The GUI is not responsive, however I can workaround using ctrl-alt-F1 and login using my password to "semi"-restore functionality. The flickering is then gone, but e.g. the dock doesn't respond correctly and my notifications are missing, until I restart gnome-shell. This then leaves me with a fully functional system again, which is why I have not regarded my issue the same as other bug reports, which report a system freeze. I have tried using gnome-session instead of ubuntu-session for the past day as of writing this report and have NOT yet experienced the issue again, so I assume it has something to do with ubuntu's theme or alike. Please provide information which log files could be helpful and I am going to try and reproduce the issue on ubuntu-session.
