Comment 0 for bug 1509326

None of these problems are readily reproducible, I'm having a roughly 30:70 chance of a successful standby or shutdown cycle.

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.

Hardware:
- Dell Precision M4600
- did a BIOS update a while ago (that changed the problems, slightly for the better I think)
- Docking station PR02X
- Two 2560x1440 Dell U2515H monitors, one on each video output of the docking station
- nVidia Quadro 2000M, using the proprietary driver (Nouveau cannot drive two 2560x1440 screens)
