Xubuntu 20.04 crashed very often

Hi,

last week I switch from Xubuntu 18.04 LTS to Xubuntu 20.04 LTS and a lot of times a day (up to 10 times a working day of 8 hours) the Session crashed. Both Monitors (connected to the docking station) and the Laptop display will be black and after a few seconds a have to login again and all unsaved work are gone... :mad:

What can I do? If you need any information, let me know. Find attached the output of DLSupportTool

Thanks in advance and best regards
Martin

Today it happens again. I've done nothing special (working in IDE), suddenly the displays went black and I had to login again. After that, I created attached log file with DLSupportTool. I had to restart the laptop afterwards because after the crash, i have a lot of problems with bluetooth connections, evolution mail client, and so on...
