[Bug 1509326] Re: Various instabilities after resuming from standby
It's my main and only work machine, I can upgrade if and only if I can easily revert any upgrade.
I don't expect to be able to revert from Wily to Vivid, so that's not an option unless I can have guarantees.
A driver update would be fine, I can always go back to Nouveau, then reinstall the current Nvidia driver.
Given #1488206 and #1507328, and that I've been having these problems
for years now, I do not expect the driver update to fix anything, but I
can still check and see what's happening. (My bets are on a race
condition somewhere in the wakeup software stack since the symptoms are
so irreproducible, but I don't know how to validate that.)
More symptoms:
9) Sometimes (rarely), X stops recognizing the screen. I get a "default"
screen @1024x768 instead of the VGA-0, LVDS-0, and DP0...DP-6
connections in xrandr --verbose. It does not help to reboot, not even
when disconnecting from all power including battery. What does help is
installing Nouveau, then reinstalling nvidia-current.
10) Sometimes (slightly more often than symptom nr. 9), I get the same as nr. 8, shutdown does not complete. I cannot get a console through Ctrl-Alt-F1, but I can Ctrl-Alt-F7 and get a graphic screen with a greyed-out desktop and an empty dialog window (there's a white title bar and a grey dialog area, but no title, no icons, no text, no buttons, no border, entirely unresponsive).
What I could do was to Ctrl-Alt-Del to get to the lock screen. From there, I could resume my normal session (just to restore the same greyed-out-with-unresponsible-dialog behaviour). I could also start a guest session, but I didn't try anything there because I believe guest isn't in the sudoers list.
Logging in with explicit user name gave me a black screen and unresponsiveness to Ctrl-Alt-F1 and Ctrl-Alt-F7, so I power cycled the machine and called it a day.

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.
Hardware:
- 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)
