Christopher, be aware that up to now I mainly tested by booting live CDs, so of course also all other packages changed as well.
But I just tested two more mainline kernels on my 15.04 system (so without changing any of the other packages): 3.12.48-0131248-generic: WORKS FINE. This is the last mainline kernel that doesn't exhibit the bug. 3.13.0-031300rc1-generic: BUG. This is the first mainline kernel that has the bug. Guess I'll now start kernel bisecting between these two versions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1296224 Title: Horrible noise via DisplayPort [regression] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1296224/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
