You won an useless use of cat award :-). http://partmaps.org/era/unix/award.html > #blacklist udl > blacklist udlfb Same settings here. > > $ cat /etc/modprobe.d/udlfb.conf > options udlfb fb_defio=1 This file doesn't exist on my system, but since udlfb is blacklisted, it shouldn't matter. Do you have a /dev/fbX device for the DisplayLink? Does /var/log/Xorg.log.0 give any information about what goes wrong? Best, Nikolaus -- Encrypted emails preferred.

However, when upgrading to 3.11.0-11-generic, X11 fails to open the DRI device with [ 8.868] (EE) open /dev/dri/card1: Resource temporarily unavailable Reverting to 3.11.0-031100-generic fixes the problem. Upgrading to current mainline (3.12.0-999.201310030405) also fixes the problem (but causes lots of kernel BUG messages). In both cases, the kernel correctly creates the /dev/fb1 and /dev/dri/card1 devices. There are no error messages in the kernel log. I can bisect this if someone tells me where to find the intermediate versions.
