USB type-c to HDMI adapter unstable display connection / Sudden Session Log Out while using MATE

Support & Help Requests

Dear community,

when starting a Java app the HTML link of external monitor (one of the two) is lost, after some seconds it's back to normal, other times the session crash.

This is a perfect explanation of what is happening:

Also in the logs I see:

Xorg: raw io port access is restricted; see man kernel_lockdown.7

How can I solve? Do you experience the same issue?

Thanks,
Francesco

Any update? I'm experiencing the same issue in Ubuntu mate 23.10. I plug the Type C HDMI adapter from my laptop to my HDMI monitor and it works fine for some time until desktop crashes and restart is needed
