[Desktop-packages] [Bug 1580296] Re: Screen is blank and won't recover
** Package changed: xorg (Ubuntu) => xfce4-settings (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1580296 Title: Screen is blank and won't recover Status in xfce4-settings package in Ubuntu: Confirmed Bug description: I am running Xubuntu 16.04, I have reproduced this problem on both the Gigabyte Brix system and the NUC5i7RYH system. Both use integrated Intel graphics. The symptom is that after a long period of time (like overnight) the screen is blanked and moving the mouse or pressing keys on the keyboard will not switch the screen back on. Using Ctl-Alt-Fx will let me bring up an alternate VT however, so I can log in and look around. Switching back to VT7 (where Xubuntu is) the screen goes black again and won't wake up. The only error message I can find is in lightdm.log which is as follows: [160363.826] (II) intel(0): Modeline "1920x1080"x0.0 148.50 1920 2448 2492 2640 1080 1084 1089 1125 +hsync +vsync (56.2 kHz e) [161295.000] (II) AIGLX: Suspending AIGLX clients for VT switch [161328.781] (II) AIGLX: Resuming AIGLX clients after VT switch [161328.781] (EE) intel(0): sna_mode_shutdown_crtc: invalid state found on pipe 0, disabling CRTC:21 If I send a SIGHUP to the session manager it restarts and the screen wakes up with the Login screen again, that of course loses all my open windows from the previous session so it isn't really optimal. The lightdm log seems to suggest that it tried to "wake up" but that something happened that wasn't supposed to. When it isn't in this state (say for example I am up and running and I use Ctl-Alt-F2 to switch to Vt2 and then switch back to lightdm it works as expected and there is no error. I've set every parameter of every screen saver locker blanker etc to never suspend block or shutdown. And the screen still blanks. That makes me wonder what agency is turning off the screen. Let me know where to look and I'll add data to this bug. The situation is quite reproducible.
