Updated Drivers from 1.0.335 to 1.2.65
Hello,
I have this dock: Product: Dell USB3.0 Dock (D3100) Manufacturer: DisplayLink And I read about the new drivers being available, and I read the change log and was pretty excited, because the issues resolve were ones I have been having for over a year. I ran the ./displaylink-driver-1.2.65.run, it ran fine. I then rebooted, now the displays dont work. The monitors are no longer detected or show up in dmesg. Network, sound and usb hub all still work. I tried downgrading back to 1.0.335, but it didnt help, I am pretty sure the firmware of the dock updated. Attached is my dlsupporttool zip file. Help, LinuxDocky Monitors: Dell Inc.-DELL 2007FP Dell Inc.-DELL 2007FP Laptop: Dell Inc.

The issue was Ubuntu has updated how it validates it kernel modules for secure boot.
I needed to disable secure boot, now even the lastest version of the drivers works. Disable secure boot in your vendor's bios, then disable it in ubuntu. I stole this part from Nevin on these vary forums: It seems that the command line used for disabling the secure boot mode was the following: sudo mokutil --disable-validation -asked for a password - restart and during BIOS step ask to type any key for modification - choose change secure boot state - enter some characters of the password -Linuxdocky |
