System freezes on resume/unlock

[Fernando Panizza]

After suspend the session the system freezes. This happens when I try to resume the
 session, in the login screen.

 To make it happen:

  1- Suspend the session from the user menu
  2- Resume the session

  Expected: The session resumes
  Observed: The system freezes

Ubuntu GNOME Trusty Tahr 20140225 i386 running on Oracle VirtualBox 4.3.6 and it seems I can't find Suspend anywhere - please see the attached screenshot.

[Tim Lunn (darkxst)]

Ali,
  The power button will turn into "suspend" when pressing <alt>. However Suspend doesnt actually work in a VM, this needs to be tested on real hardware.

[Tim Lunn (darkxst)]

@Fernando,
  - When does the freeze occur? Does the login screen get drawn? can you type you password in etc?
  - You are using missing the \:*-greeter.log files from /var/log/gdm, can you attach them
  - Seems you have auto-login enabled? Does this still happen if you disable that?

@Tim

Hi, the problem is, I don't have any real hardware to test Ubuntu GNOME :(
I had two machines (laptops) which can handle Ubuntu GNOME and was thinking to use one of these but sadly, one is dead so I have only one right now which I can't really take the risk to try anything not stable simply because I can't pay now for new hardware. So, I don't have any other option :(

I have other machines but all with 512MB RAM which won't be helpful.

Thank you!

 It happened after hitting any key in order to resume the session in the same time that the login screen should be displayed.

> - Does the login screen get drawn?

With GNOME 3.8 it showed the login screen and then freeze before I could tipe any password or username.
With GNOME 3.10 the screen turns black and then freeze.

 can you type you password in etc?

With GNOME 3.8 I couldn't tipe anything
With GNOME 3.10 it allows to start a VT!

> - You are using missing the \:*-greeter.log files from /var/log/gdm, can you attach them

As soon as I get to my testing machine I'll send it.

> - Seems you have auto-login enabled? Does this still happen if you disable that?

Yes it happens. I had enabled auto-login to see if this happened when enabled.

[Fernando Panizza (fernan-domp-deactivatedaccount)]

The files are from another installation using beta1 for i386 in wich the problem can be reproduced.

[Tim Lunn (darkxst)]

Fernando, still no greeter logs :(

can you try with lightdm and see if you hit the same freeze issue?

[Fernando Panizza (fernan-domp-deactivatedaccount)]

The files I've sent were all in /var/log/gdm, I've listed with 'sudo ls -a' and couldn't find any greeter log.

I have to install lightdm and I'm having some problems with the network manager GUI (I'll send a report on that), as soon as I get my connection to work I'll test it with lightdm

[Fernando Panizza (fernan-domp-deactivatedaccount)]

Sorry, I was using a bad iso, here are the greeter logs form a new installation

[Fernando Panizza (fernan-domp-deactivatedaccount)]

it seems to occur only with the nvidia GeForce video chip, in my notebook wich has an Intel Graphics this doesn't happens. I've tested with light dm and the result was a black screen after booting. I'll run more tests on a new installation were I'll test each of the aditional drivers and run more tests with light dm.

[Oliver Jan Krylow (okrylow)]

I can confirm this bug on another Distro. Using Arch with Gnome 3.12 and Nvidia GeForce. The lock screen is frozen, mouse cursor visible and movable but UI does not react. Keyboard input works, but has no "visual effect", I can switch TTY and type commands blindly but the lock screen remains frozen.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Omission5311 (omission5311)]

Still an issue with Nvidia 660 Ti running propriety drivers on Ubuntu GNOME 16.04.1.

Freezes within 1 minute of resuming 100% of the time (about 12/12 so far before disabling it).

[Devon (devonfyson)]

Still a problem in Ubuntu 18.10 on Acer Swift 3. With screen blanked, on resume, it occasionally hangs to leave a blank screen and the side bar.

To recover from it, I switched to another tty (Ctrl-Alt-F3 for example) then ran "killall gnome-shell" and gnome-shell would restart by itself. However now for some reason I need to do "export DISPLAY=:0; gnome-shell -r &"

The side bar is then missing and the display blanks after 15 seconds.
