ZBook Studio x360 G5 - No HDMI or USB-C Monitor on Linux After Firmware Upgrade

ZBook Studio x360 G5
Linux

Not sure if anyone else has experienced this, but I normally run my laptop in intel mode (I blacklist the nvidia modules) without issue.  I've upgraded my firmware, and now there's no output via USB-C or HDMI.

 

When I connect a USB-C monitor, no signal is detected.  In Linux (Arch), dmesg shows a USB root hub is detected, but my external display does not appear in xrandr and the monitor just goes into power saving mode.

 

If I downgrade firmware to 01.07.00 Rev.A, my external monitor works again via USB-C and HDMI.  From what I can tell, the issue first appeared in 01.08.00 Rev.A.

 

Has anyone experienced similar? Has there been a change in the firmware that would affect how the iGPU maps to the HDMI and USB-C ports?  Seems firmware bugginess (which Windows developers work around, particularly ACPI) seems to cause a lot of grief with other OSes..

 

Running Arch with 5.5.13 kernel, Xorg without configuration (hasn't been needed until now), nvidia kernel modules blacklisted, i915 kernel module is loaded..

 

Thanks!
