I can confirm this seems to be a v3.8 bug. I get the same symptoms on amd64 3.8.0-25.37 (current raring kernel), and 3.8.0-27.39~pre201306280400 (current raring kernel-ppa pre-proposed.)
When I installed a v3.9 kernel (I used 3.9.0-030900.201304291257 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/ ) my DisplayLink adapter "just worked" when hotplugged. I see a few udl-related commits in the mainline changelogs for 3.8.1 & 3.8.8. Is there much possibility of the fix being backported to the raring kernel? - Angus -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1183868 Title: Displaylink open /dev/dri/card1: Resource temporarily unavailable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-modesetting/+bug/1183868/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
