black screen after logout using gnome 3.2 lightdm

[Lukki]

Release: Ubuntu 11.10 Oneiric
User Interface: gnome 3.2
loginmanager: lightdm

After logout from gnome-shell the system keeps running, while the screen is totally black.
What i expected to happen is seeing the lightdm login shell.
Entering the password is logging in the user again, but there is no visual response to entering the password and pressing enter, before the desktop appears.

Gnome Shell has been installed using the Ubuntu Software Center. The whole login works as designed when booting the system.

The background-image used in lightdm has been changed using the configuration file,
so that it is using a different image form another path.
After booting the image is shown properly as background of the login manager.
The image does not seem to be a problem, as other users report the same behaviour, using standard settings in lightdm.

I am not connected to the person reporting the same problem here:
http://askubuntu.com/questions/85788/ubuntu-11-10-with-gnome-shell-does-not-logout-properly
but the behaviour described is the same.

I am using a thinkpad x220 with intel sandy-bridge internal graphics.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/909176/+editstatus and add the package name in the text box next to the word Package.

Thanks for your bug report. I gave this a shot on my x220. Upon logging out, my screen is black for maybe half a second, but redraws after that, which might just be normal behavior. I don't have a custom image for my login screen, in the event that ends up being relevant. In any case I'll open a task against xorg. Could you please run "apport-collect 909176" in a terminal? That'll add some detailed system information to this bug report

ok it is more than obvious now where you can find the information.

[Lukki (lukki)]

The only reason why i realized it is possible to login again is that the fingerprint sensor was showing a green light. But the fingerprint gui is probably not af any importance here, as the problem has already been existing before the installation of the fingerprint gui.

[Phil. V (philip.v)]

Thanks for running apport. I'm not familiar with debugging problems like this, but with that information attached hopefully someone more informed can see what's wrong.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.3 kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.3-rc4 fixed the issue, the tag would be: 'kernel-fixed-upstream-v3.3-rc4'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I expect the same behaviour here after changing the system hardware from a nvidia card. I am using a sandy brigde graphics now (xeon) - which is the case in this bug as well.

  VGA compatible controller: Intel Corporation Xeon E3-1200 Processor Family Integrated Graphics Controller (rev 09)

If I run

  lightdm --test-mode

with xephyr, I'll get a correct result (the given picture shows up). So settings seem to be OK:

cat /etc/lightdm/unity-greeter.conf

[greeter]
background=/home/me/.cache/gnome-control-center/backgrounds/05f06bfdd4b978cb282f07ee7b1dc3849215ff85ea6467378e40caa5c3330855
logo=/usr/share/unity-greeter/logo.png
theme-name=Ambiance
icon-theme-name=ubuntu-mono-dark
font-name=Ubuntu 11
xft-antialias=true
xft-dpi=96
xft-hintstyle=hintslight
xft-rgba=rgb

These issues occure with the mainline 11.10 Kernel as the new 3.2.7-ppa Kernel as well.

So this seems to be a graphics hardware/driver issue?!

Same problem with
