rawhide-release-19990901-1

gdm is denied access to the Xserver... and cannot start up.
I also tried KDE and AnotherLevel in the
/etc/sysconfig/desktop file.  KDM and the XDM work okay as
long as you don't choose GNOME as the session type. Moving
back to init level 4 and running a startx works fine for
gnome.  root and normal user work the same.

An strace on the gdm process shows it looking for
/root/.Xauthority while on a functional system running
rawhide-release-19990730-1, gdm correctly finds the
/var/gdm/:0.xauth file.

Relevant /var/gdm/:0.log contents:

AUDIT: Fri Sep  3 11:34:06 1999: 1968 X: client 1 rejected
from local host
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server

------- Additional Comments From   09/03/99 14:08 -------
Also, the /etc/X11/prefdm needs to be modified before the
/etc/sysconfig/desktop grep works properly.

The grep sections need to be of the form:

   if [ -n "`grep -i GNOME /etc/sysconfig/desktop`" ];

and the exec section needs to be:

if [ -n "$preferred" ]; then
        exec `which $preferred` $*

Comment 1 dwsmith 1999-09-03 17:14:59 EDT
I should also note that I have been running all versions of rawhide on
top of an original install of Redhat 6.0.  I do not upgrade the
kernel with the rest of the rawhide package.  I build my own kernels.
Comment 2 dwsmith 1999-09-09 19:26:59 EDT
Please close this issue.  The bug was resolved with this latest
release of rawhide... rawhide-release-19990907-1

Thankyou.

Note... the /etc/X11/prefdm script still echos "/usr/bin/gdm"
to the terminal when starting up.  Benign, but doesn't look good.
