So, I tried Xubuntu 16.04 on that machine and it made progress, but not completely fixed. It still doesn't work with the DP2HDMI adaptor: TV off, TV on -> black screen. "sudo service lightdm restart" works too for bringing the screen back up. But, with a VGA to HDMI converter it now works. For some strange reason it didn't work on Xubuntu 14.04 even tho it worked when directly attached via VGA. Anyways, it doesn't work via DP (DP2HDMI adaptor). It's probably the same problem. This is not a duplicate because this machine does not have a Nvidia GPU but Intel on-board graphics. I'll post more info soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575123 Title: [Xubuntu 16.04] Display stays black if monitor is turned off/on To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-settings/+bug/1575123/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
