Hello, everybody.

My notebook (ThinkPad T530) apparently goes into sleep mode according to the log (see below). In reality it hangs up: The screen (backlights) stays on, but shows no content (black image). The device can't be woken up anymore. I have to switch it off (Power Off for 5 sec.).

The problem occurred immediately after upgrading Kubuntu from version 19.04 to 19.10. The system was put into operation years ago with version 14.04 and has not been reinstalled since then, but has always been upgraded to the next version by "do-release-upgrade".
