I also see the modules loaded in lsmod, but nothing in xrandr or lsusb?!?
I see a complain in dmesg about: evdi: module verification failed: signature and/or required key missing - tainting kernel Is that related? Secure boot is disabled in bios Running on a Lenovo X250 /Termo Quote:

Hello,
The problem raised by mourngrym seems to be a valid bug which is already reported internally and were able to reproduce it. Thank you. Termo, Your problem is completely different. Could please report it in a separate thread and mention what kind of DisplayLink device you are using? I don't see it anywhere connected. Szymon |

HI, i'm not quite familiar with the technicalities. i tried to add the line "blacklist udl" at the bottom of /etc/modprobe.d/blacklist-framebuffer.conf, is that correct?
my 99-displaylink.rules is ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="17e9", ATTR{bNumInterfaces}=="*5", GROUP="plugdev", MODE="0660" is that correct? because i'm using a wacom dtu-1031 and i know the vendor id for wacom is 056A. I've added the blacklist udl and the problem still persists. Please let me know what should i do exactly. Thanks! |
ubuntu crash when usb is unplugged

I've updated to the latest displaylink driver 1.2.65, however, unplugging a displaylink device (Wacom DTU-1031) still causes the system to crash. It doesnt happen if i unplug other usb devices.
