[rhelv6-list] Changing login display manager

[Michael Coffman]

Is there a way to get to a login screen that resembles what was
available on rhel5?   I would like to have login screen that allows
the user to choose different window managers at the login.

As a side note, I tried updating /etc/sysconfig/desktop.   XDM works
but gives no WM selection possibility.  KDE fails miserably with
kdmgreet crashing.  the following is from /var/log/kdm.log:

(EE) [drm] failed to open device
(EE) open /dev/fb0: No such device
error setting MTRR (base = 0xf5000000, size = 0x00e00000, type = 1)

KCrash: Application 'kdmgreet' crashing...

Thanks for any pointers or info.
