Julius,

I am in the same boat now you are...read below.

Eric, I hacked my setup by dumping "getent passwd > /etc/passwd" and
disabling ldap account checking (it still auths/passwd via kerberos
thank goodness).  Thanks for the tip on nscd.  For some reason
everything I had read previously said to turn it off.

I've got extreemly slow logins (rest of the session runs fast). When a
client comes up, the screen stays gray for longer than usual, and then
when the user logs in, it pauses after they have entered their
password.  It almost seems like GDM is taking awhile to run the
pre/post/init scripts.  I once fixed a similar problem by running
gdm-safe-restart (I had a lab full of gray screens, and then one by one
they all blinked on.. it's not helping right now).  Try logging into
your server from another linux box via Xnest & XDMCP (I used tsclient to
configure the options). I get a black screen and then finally the login
screen (much longer than it used to be).  VNC is slow as well.

I do have systems that get wacked as well while the user is still using
them.  The only things I have done recently are:

setup vnc via the X module method
(http://wiki.ltsp.org/twiki/bin/view/Ltsp/WorkInProgress#VNC_SO)

and ran a ton of updates yesterday AM that included Xorg.  BTW, I am
running 4.1.1
