Comment 12 for bug 851612

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.
