If I go to tty1 or tty2 I'm pulled back to tty7 (?) within seconds. sometimes if I ctrl-alt-del I'm sent back to the login screen and from there I can resume the session. everything was working fine with my previous (1920x1080) display, but since I switched to a 3840x2160 display the only reliable solution to get the computer back from blanking is pressing the power button. I can then see the shutdown "splash" and after powering it back again everything is back to normal. until it blanks the screen again obviusly ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xorg 1:7.7+13ubuntu3 ProcVersionSignature: Ubuntu 4.4.0-78.99-generic 4.4.62 Uname: Linux 4.4.0-78-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.5 Architecture: amd64 CurrentDesktop: XFCE Date: Mon May 22 19:16:43 2017 InstallationDate: Installed on 2015-12-27 (512 days ago) InstallationMedia: Xubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) SourcePackage: xorg UpgradeStatus: Upgraded to xenial on 2016-04-27 (389 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1692671/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
