I have installed RH 6.1 from scrath on both the i386 and the sparc plattform. When gdm starts, there is no Red Hat logo in the top left of the screen. When I did an upgrade from 6.0 to 6.1 for i386, I got a nice logo.
In the /etc/X11/gdm/Init/Default script, the following test if performed: # only set the background if the xsri program is installed if [ -x /usr/bin/xsri ]; then /usr/bin/xsri -geometry +5+5 -avoid 300x250 -keep-aspect \ /usr/share/pixmaps/redhat/redhat-transparent.png fi Could you confirm that the files /usr/bin/xsri /usr/share/pixmaps/redhat/redhat-transparent.png exist on your system?
The package xsri is not installed. So that should explain the missing logo. Don't know why this wasn't included in the install. Maybe I didn't select it or deselected it under the installation...
