Title:
hirsuit kernel fails to detect monitor plugged into USBC thunderbolt
socket
Status in linux package in Ubuntu:
Expired
Bug description:
On upgrade to hirsuit hippo, my Dell 9360 no longer detects a monitor
plugged into the thunderbolt usbc socket. If I reboot with the latest
kernel from Ubuntu 20.10 (version 5.8.0-50) it works perfectly,
detecting the monitor from kernel boot.
I have tried both a thunderbolt cable, where usb devices plugged into
the monitor are detected, but the monitor itself is not, and a
usbc<->displayport adaptor that puts the socket straight into DP
alternate mode. Neither work in 21.04.
Happy to try and debug this, but not sure where to start!
