Still no progress on finding out why this is occurring. Some speculation: - ConsoleKit is intercepting the VT switch and stopping it working. GDM uses ConsoleKit to do the VT switching but this is not easy to do in LightDM with the current architecture (it doesn't assume that CK is available, it switches before the session is started). - The X server is not correctly getting the frambuffer when the VT switch occurs - unlikely as it's not occurring with GDM, but could be a timing issue.
Need some Kernel/ConsoleKit/X experience to find where what stage of the VT switch is failing. -- 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/851612 Title: Logging out from a FUS session does not reliably return to VT7 Status in Light Display Manager: Triaged Status in “lightdm” package in Ubuntu: Triaged Status in “xorg-server” package in Ubuntu: New Status in “lightdm” source package in Oneiric: Triaged Status in “xorg-server” source package in Oneiric: New Bug description: Steps: 1.
