I recently got a Dell U2414hb monitor, and it is affected by this bug. I would really appreciate if someone has found a fix and is able to explain in simple steps how to do it.
The steps above sound a bit advanced for me, but I am willing to try things out if it will help. I tried: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date And I got: A07 -- 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
