Hey, good news! I noticed my firmware was at version 1.0.0 and version 1.1.1 is available on the Dell website. I downloaded the firmware and updated the firmware using the instructions found here. The firmware update completed successfully, and now all three USB-C ports function as expected! [NAME] Potapov, I don't know if this will solve your issue, but it may be worth a try. Good luck! David
Hi, I'm thinking about contacting support about this because it should be under warranty, but I'm worried they may blame this issue on Ubuntu. I recently purchased a Dell XPS 13 9380. I'm having a problem with the "Thunderbolt 3 (USB Type-C) port with Power Delivery (Primary)" on the left side of the laptop, page 7 in the XPS 13 9380 Setup and Specifications PDF. I can still charge the laptop using this port, but no other device is detected when I connect them to the computer using this port. If I plug the same devices into any other port the computer recognizes the device and I am able to use it. The laptop came with Windows 10 Home, but I installed Ubuntu 18.04 on the first day, This port has worked in Ubuntu since I bought the laptop. It was working as recently as this morning. It only stopped working today. Has anyone experienced any issue like this? Do you think it's software related or hardware? If I contact support will they care if I'm running Linux, or will they expect me to reinstall Windows first? I would like to avoid installing Windows unless absolutely necessary. Thanks, David
