Xubuntu 20.04 crashed very often

[dj-digger]

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...

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
