I have similar problem. imac 27" with Ubuntu 18.04 LTS, 4.18.0-25-generic Thunderbolt display VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 775M Mac Edition] (rev a1)
Sometimes, after logging in, both screens are on. After shutdown, the second screen sometimes is off. Then, I have to restart and it could or couldn't work. Looks like random behavior. It would be good to have the second screen on since the boot startup. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1771185 Title: Secondary monitor not connecting in 18.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1771185/+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
