Dell Precision 5530
Latest 5530 BIOS (1.13.0)
ikling usb-c hub
5.0.0-32-generic

I dont think this has anything to do with the Dell HUB as noted above Im not using it but some off brand. Using ethernet, hdmi and one usb 3.0 port. I see the screen attached every 30 minutes or so go blank then become active within a second or two. At this time I also lose network and the USB. All devices come back but it disrupts vpn connections. Its extremely problematic. This is also connected to a usb kvm switch which I use to flip between the two systems. I have not noticed this bouncing back and forth to be related so I dont think disconnects of usb devices impact it. I see similar logs as those posting above.
