re: this post From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> http://www.spinics.net/lists/linux-pci/msg57021.html Bjorn, try the adapter being disconnected until the system is booted, and you're at the DE or even already logged in. Then connect the adapter, and then the display. What I'm experiencing on an HP Spectre with Thunderbolt/USB-C/USB 3.1 Gen 2 ports and a USB-C to USB-3 adapter is it doesn't work if connected at boot time. If it's connected after startup, then it works OK. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
