Can you give me some instructions how to nail down the actual cause of these problems? The symptoms are so varied and instrutable, it almost looks as if some race conditions deep down in the software stack leave stuff in inconsistent state. Logging pertinent status information for each startup might be a good start.
The system is showing the login screen even though everything has been configured to not show the login screen. Finding out the reason why would be a good start, then I'd look for the reasons for the reason, until the root cause is found. (This might even be a hardware glitch, but without any pointers to a concrete failure I can't turn in the machine for fixing. Also, if it's a hardware problem, it would be worth it submitting a bug report to whatever software subsystem should have logged it.) ** Changed in: xorg (Ubuntu) Status: Expired => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded 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.
