I just upgraded my Ubuntu installation from 13.04 (kernel 3.10.0-031000rc7-generic) with a USB Displaylink working just fine to 13.10 after loading the new kernel the usb displaylink stopped working. After reading this thread I tried 3.11.0-031100-generic as well which didn't work for me.
Here a summary of my settings $ cat /etc/modprobe.d/blacklist-framebuffer | grep udl #blacklist udl blacklist udlfb $ cat /etc/modprobe.d/udlfb.conf options udlfb fb_defio=1 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1234818 Title: Regression: DisplayLink DL-195 fails with EAGAIN after upgrade from 3.11.0-031100 to 3.11.0-11 Status in “linux” package in Ubuntu: Confirmed Bug description: My Plugable UGA-2K-A USB 2.0 to DVI adapter (using chipset DisplayLink DL-195, USB ID 17e9:4302) works fine with 3.11.0-031100-generic. 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.
