Today it happened to me again and after unplugging and replugging the monitor 10 times it worked!!!
It almost makes me feel it must be a HW issue but: - I'm using two different displayport adapters (DP to VGA at home DP to HDMI at work) - it never ever happened during a powering on (have powered up my laptop at least 20 times after this issue begun) - a reboot *always* fixes the problem (have tried it at least 10 times) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1300914 Title: External screen undetected after first plug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1300914/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
