Bug ID: 198587
Summary: Thunderbolt 3 → VGA adapter does not work anymore.
Product: ACPI
Version: 2.5
Kernel Version: 4.14.15-1-ARCH
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Config-Hotplug
Assignee: acpi_config-hotp...@kernel-bugs.osdl.org
Reporter: bruno.n.pag...@gmail.com
Regression: Yes
When I try to connect to a VGA projector through a Thunderbolt 3 → VGA adapter,
it does not work. It used to work the last time I had to do this, which was in
May 2017, running linux 4.10 or 4.11.
I’m opening this bug report against ACPI because this is what I see in my
dmesg:
– upon plug-in:

Please tell me what information are required for this bug to be solved and what
should I do to help you fixing it.
Note: I’ve tested two different adapters from two brands (Moshi and Apple),
both exhibit almost the same results. I’ve also recorded `udevadm monitor` logs
in case those could be useful.
