Daniel,
Tnx for the prompt reply. Here are my findings: re 1.: /var/crash is empty. There are no files. Just to let you know://Immediately after I logged in, I switched to one screen mode. The system did not crash. I assume, that older crash files should be in /var/crash from earlier crashes. Again: Nio files. re2.: Here is the required link. I replaced the string 'ID' with the content of whoopsie-id: https://errors.ubuntu.com/user/5fd549dc7d50ea7eb81a704d3d2508e0449eaf07c1bdac5a59b01203286966824e3c72d60dc218f5ed382637afa126117fc43d759958cb058b07afa624e85a14 Strange enough, it leads me to a Nautilus error with the date Oct. 15. I think I still ran Ubuntu 18.04 in October - to my best knowledge. And I cannot imagine, that Nautilus has got something to do with my system freeze. re 3.: I did not manage to find out what the workaround from bug 994921 could be. Nevertheless I send this email now and will revert to dual screen mode again and see what's happening. As I said: If the bug with the system freeze occurs, the system becomes unusable. There is even no reaction to key strokes. I only can force my system down be pressing the on/off button. If this is of any help: I still have an 18.04 partition running on the system, which runs flawlessly. Could this be of any help for error detection? Tnx for the time being, I will let you know of further outcomes.
