I have similar problem. Acer Aspire VN7-792G with Nvida GeForce 960M and Ubuntu 18.04.2 LTS. Try to connect to monitor Asus vx239h.
Sometimes it turns out to connect a second screen as an extension of the screen, for example, if you go into console mode and return. It works for a while, when you try to enter Settings, the screen turns off. -- 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
