Just got the external screen in the same state again (ie, blank) after leaving the desk for 5-10 minutes.

Switching it's input from it's usual DP input to another one, and switching back again does restore the image. -- 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/1799920 Title: External Dell P2715Q doesn't wake up from standby anymore after 18.04 -> 18.10 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1799920/+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
