Hello Alistair, or anyone else affected, Accepted lightdm into saucy-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/lightdm/1.8.6-0ubuntu1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

[Desktop-packages] [Bug 1256150] Re: Xorg guest session fails to start if the user has logged out and logged in again
I now know exactly what causes this bug. The problem is that the VT gets unref'd once when the server shuts down, and then unref'd again much later when the object gets finalized. This might happen after the VT has already been allocated and ref'd to another server. This makes lightdm think the VT is free, when it isn't.

[Desktop-packages] [Bug 1256150] Re: Xorg guest session fails to start if the user has logged out and logged in again
** Also affects: xorg (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1256150 Title: Xorg guest session fails to start if the user has logged out and logged in again Status in “lightdm” package in Ubuntu: Confirmed Status in “xorg” package in Ubuntu: Confirmed Bug description: Steps to reproduce: 1. Log in to the desktop. 2. Log out again. (But don't reboot or anything like that.) 3. Log in again. 4. Start a guest session. Result: Depends on Xorg server in use. With intel driver, the guest Xorg session fails to start up with a DRM permission error (see attached Xorg.1.log). With virtualbox, and possibly AMD proprietary driver, the Xorg session on :1 appears to fight the one on :0 for control of the framebuffer - windows from both desktops get drawn over each other, causing a big mess. The login/logout step is important: if you log in to the desktop immediately after the lightdm session has been started or restarted ("sudo service lightdm restart"), then the :1 session will start correctly. (This problem can also be reproduced in another way: some desktops, when locking the display, create a new greeter instance on :1. This will also fail if the user has logged out and logged in again. For example, Xubuntu does this.)
