On the boot issue, I also experience the problem that X doesn't start with external monitors plugged in. I'm running Kubuntu 16.10, upgraded from 16.04.
Kernel: 4.8.0-26 I have two external monitors connected to my laptop, one VGA, one HDMI. Whether or not I have the laptop lid open, if the external monitors are plugged in, X won't start. To get things going, I have to issue sudo service sddm start from a terminal. Then all is fine. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1631519 Title: No X on boot with external monitor connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1631519/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
