The login screen hangs for a while after boot

[Lars Ola Liavåg]

Binary package hint: gdm

I have a fairly fresh Lucid system installed from scratch over Karmic. In Lucid, I often experience that the lightning-fast boot presents me with a login screen as expected but when clicking on a user, using the arrow keys, or pressing enter, it turns out to be completely frozen. After a lag of typically several seconds (~10), the response comes and at that time, the user may have clicked around a lot, which typically results in "authentification error" and the need to do the login over again. Utterly annoying, of course.

Looking in the log files, I see warnings like:

gdm-session-worker[1287]: WARNING: Unable to load file '/etc/gdm/custom.conf': Filen eller katalogen finns inte
gdm-binary[880]: WARNING: Unable to find users: no seat-id found
gdm-simple-greeter[1379]: Gtk-WARNING: /build/buildd/gtk+2.0-2.20.1/gtk/gtkwidget.c:5636: widget not within a GtkWindow

I don't know if they are connected or relevant at all but include them here just in case. Please let me know if I should provide more input.

It seems this bug is a duplicate of bug #555169 so I'm marking it as such. So far I have good experiences with writing a new xorg.conf from the NVIDIA X server settings application. I'll wait a little longer before I conclude but it seems my problem may have been solved by this trick.
