Cause: Inadequate logic for determining when to force the X server to run on virtual console 1.
Consequence: The login screen and subsequent user sessions jumping to virtual console 7 after the initial log out.
Fix: A change in logic to force virtual console 1 for the statically hardwired display.
Result: Only auxillary displays needed for user switching run on virtual console 7 and later. The main login screen / user session always runs on virtual console 1.
