Lonnie Lee Best, thank you for reporting this and helping make Ubuntu better.
1) Is this something that started to happen after an update? If so, which and when precisely? 2) To clarify, could you please describe how your computer is connected to monitor (e.g. using a HDMI cord connecting both, using a dongle/adapter, etc.)? 3) Regarding the use of kernel boot parameter acpi_backlight=vendor is this required? If you remove it, is this issue still reproducible? 4) If you remove the nvidia drivers and use nouveau, is this reproducible? 5) As per nvidia.com the latest driver version available for your card is 390.59. hence, to see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- 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/1771062 Title: LG 27UK650 Monitor Won't Come Back On After Inactivity Turn Off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1771062/+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
