I am on 4.15.0-20-generic now installed, reboot. Same situation as before. 1. folder /sys/class/typec does not exists 2. CONFIG_TYPEC_UCSI=m CONFIG_UCSI_ACPI=m 3. xrandr do not see the external DP monitor 4. Finally, this output:

The fix just changes a timeout setting, allowing the probe to succeed in those cases there is load on the system. [Test Case] During boot, with the system at load, the probe would fail some times. With the increased timeout for firmware responses, that doesn't happen after many reboots. [Regression Potential] This would only impact systems that have this specific ACPI node. As the probe runs on a work queue, this should not impact boot time.
