[KLUG Members] Screenshot of Login Dialogue

[Buist Justin]

I thought it was kind of funny that I got asked the same question today.  Then I realized it was a BIS 555 student at WMU who had the same question on one of their assignments :)... but I did come up with something.

First, I'm running gdm/gnome here, and on Debian.  Locations of files may change and such but it should be fairly simple to figure out where they are on your distro of choice.

1)  I made sure that X was listening on tcp first.  If you've got an "-nolisten tcp" being passed to X from gdm/xdm/kdm.conf then you might need to modify this and restart gdm/xdm/kdm.
2) Ctrl+alt+f1 to drop to a console login.
3)  cp /var/lib/gdm/\:0.Xauth ~/.Xauthority
4)  xwd | convert xpm:- jpg:login.jpg
5)  alt+f7 back to the X session and mouse-click on the root window.  I did try xwd -root | convert xpm:- jpg:login.jpg but that didn't want to fly.  I got one garbled looking image from it.  I have no explanation for that.

'convert' is part of the ImageMagick tools... I didn't want to try and figure out how to view a raw xwd dump.

I very well might have "improperly" given myself permissions to connect to the X server, but it works.  I'm not familiar with the nitty gritty details, so if somebody feels I should be doing it differently -- let me know.

But... that pretty much does it.
