I still have the same problem with kernel 3.13.0-35
I'm sorry, I didn't have the time to bisect; this is my work laptop and it's not so easy to install many kernels. The tests I did: 3.12.0-031200: GOOD 3.13.0-24: BAD after 5 sleep/wake up 3.15.0-031500rc8: BAD after 1 sleep/wake up 3.13.0-35: BAD after 2 sleep/wake up I'll try to bisect more properly when I have the time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1322644 Title: [Dell XPS 13 (L321X)] External monitor does not wake up after sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1322644/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
