11) Did a reboot because graphics performance had dropped. Reboot through XFCE desktop would make the screen go black, pstree showed that the desktop still lived. reboot command from console would work, but boot into a black screen (after a brief display of a background and something that might have been the mouse pointer). Closing and opening the lid would not help, detaching the laptop from the docking station and Ctrl-Alt-F7 would restore the XFCE desktop, reattaching to the docking station would give access to the docking-station-connected screens. So... something wasn't properly initialized with the docking station attached during boot.
For reference, I have placed the following script on a hotkey to switch from laptop to docking-station-connected screens. #! /bin/sh echo ================================================== >>/home/jo/xrandr.log echo docked.sh >>/home/jo/xrandr.log date >>/home/jo/xrandr.log echo >>/home/jo/xrandr.log xrandr --output DP-6 --auto >>/home/jo/xrandr.log 2>&1 xrandr --output LVDS-0 --off >>/home/jo/xrandr.log 2>&1 xrandr --output DP-3 --auto --left-of DP-6 --primary >>/home/jo/xrandr.log 2>&1 It's extremely rigid and unable to deal with any variation in the hardware situation, and sometimes is fails to disable LVDS-0 and cannot activate DP-3 afterwards (I think because there are only two CRTCs), but if all hardware is properly detected, it will work reliably on the second attempt... barely good enough so I don't have to redo Display configuration every time it fails to auto-reconfigure when attaching to or detaching from the docking station. -- 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/1509326 Title: Various instabilities after resuming from standby Status in xorg package in Ubuntu: Incomplete Bug description: None of these problems are readily reproducible, I'm having a roughly 30:70 chance of a successful standby. Things that I have seen happen: 1) Click on Whisker menu -> Logoff ("Abmelden") button -> Logoff/Restart/Reboot/Standby dialog (no Hibernate option, I think it's blacklisted for my machine) -> Click on "Shutdown" -> no shutdown, I get the login screen. 2) Trying to go to standby from the Logoff button in the login screen after seeing (1) -> monitor switches off, then on, login screen again. 3) After (2), close the lid, open it, standby procedure from login screen -> works. Sometimes. 4) After (2), remove machine from docking station, standby procedure from login screen -> works. Sometimes. 5) Machine is in standby, I press the power button, I get some text mode messages, monitor flashes and shows graphic content (mostly a mouse cursor on some background, too fast to properly see), then the screen goes dark. Ctrl-Alt-F1 works, Ctrl-Alt-F7 simply makes the screen dark again (both the builtin laptop screen and one of the external, connected-through-docking-station screens). 6) The effects from (5) can also happen right after cold booting the machine. 7) I *think* on a few occasions, I tried to shutdown the machine and nothing happened at all. 8) On some rarer occasions, nothing would happen after the shutdown command, and trying to issue another shutdown resulted in a message amounting to "can't do another action while the previous action is in progress"; I remember pstree reported some hung process that was connected to shutdown, and I couldn't kill it (not even kill -9). I cannot reproduce this, and I didn't take notes so I can't be more specific. I have no idea which of these effects are related to a common cause and which are independent. I have been unable to find out anything given that no individual phenomenon is reproducible with any reliability. I hope the attached debug info will help, but I fully expect this to require much more diagnosis.
