After taking a backup for 16.04 (in case this very thing happened), I installed the daily build of 18.04 as it didn't really make sense for me to hold on to a distro that'll be replaced in a couple of months. I noticed there were a few Dell repositories in sources.list, but non of them have bionic endpoints (only xenial). I copied those, in case they would be useful and went to erasing the disk and installing 18.04. Everything seems to work fine, except the USB / Thunderbolt ports. Nothing I try works, whether it be USB or Thunderbolt 3. If I look in dmesg, I can see the controller is recognising something, but it never lands in userspace: [ 1807.837379] xhci_hcd 0000:39:00.0: Host supports USB 3.1 Enhanced SuperSpeed [ 1807.837410] usb usb4: New USB device found, idVendor=1d6b, idProduct=0003 [ 1807.837412] usb usb4: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 1807.837413] usb usb4: Product: xHCI Host Controller [ 1807.837414] usb usb4: Manufacturer: Linux 4.13.0-25-generic xhci-hcd [ 1807.837416] usb usb4: SerialNumber: 0000:39:00.0 [ 1807.837549] hub 4-0:1.0: USB hub found [ 1807.837558] hub 4-0:1.0: 2 ports detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1745747/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
