When reporting this bug, I called it a regression because an older kernel package worked, but a more recent one did not. I did not realize that the older one was mainline, and the later one with Ubuntu patches.
The system runs Ubuntu raring. Since raring comes with a 3.8, which I believe does not fully support the DL-195, I installed a 3.11 kernel from Saucy (but nothing else). When at some later point I updated to a more recent Saucy kernel (apparently this time including Ubuntu patches), things stopped working. So yes, I would say it's possible that this has never worked in Ubuntu but only in mainline. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1234818/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
