Bug#553362: gdm: lenny->sid upgrade weirdness

[Michael Gilbert]

package: gdm
version: 2.20.10-1
severity: important

i recently upgraded a machine from lenny to sid.  in the process, it
was stated that some services needed restarted (i think in order to
upgrade libc), which including gdm. i figured i might as well do it.

however, in the process gdm came up with a dialog that said it could
not restart because an x server was already running on :0.  the two
options were "yes", which tried to launch a new x server over and over
again and eventually failed; and "no", which tried to launch on :0
again, but failed. both options flash the screen a bunch and are
not very professional looking.

is there any better way that this could be done?  is a gdm restart
really needed?  would it be ok to use the present gdm and wait for the
user to reboot (or at least log out) to launch the new version?
