3 Try to log in from a console (using [Ctrl] + [Alt] + [F1]). If this is successful,

the blame cannot be put on PAM, because it is possible to authenticate this

user on this machine. Try to locate any problems with the X Window System

or the desktop (GNOME or KDE). For more information, refer to Section 9.4.4,

“Login Successful but GNOME Desktop Fails” (page 143) and Section 9.4.5,

“Login Successful but KDE Desktop Fails” (page 144).

4 If the user's home directory has been used with another Linux distribution,

remove the Xauthority le in the user's home. Use a console login via [Ctrl]

+ [Alt] + [F1] and run rm .Xauthority as this user. This should eliminate X

authentication problems for this user. Try graphical login again.

5 If graphical login still fails, do a console login with [Ctrl] + [Alt] + [F1]. Try to

start an X session on another display—the rst one (:0) is already in use:

startx -- :1

This should bring up a graphical screen and your desktop. If it does not, check

the log les of the X Window System (/var/log/Xorg.

displaynumber

.log) or

the log le for your desktop applications (.xsession-errors in the user's home

directory) for any irregularities.

6 If the desktop could not start because of corrupt conguration les, proceed

with Section 9.4.4, “Login Successful but GNOME Desktop Fails” (page 143) or

Section 9.4.5, “Login Successful but KDE Desktop Fails” (page 144).

The following are some common reasons why network authentication for a particular

user may fail on a specic machine:

• The user may have entered the wrong password.

• The username exists in the machine's local authentication les and is also pro-

vided by a network authentication system, causing conicts.

• The home directory exists but is corrupt or unavailable. Perhaps it is write pro-

tected or is on a server that is inaccessible at the moment.

• The user does not have permission to log in to that particular host in the authen-

tication system.

• The machine has changed hostnames, for whatever reason, and the user does

not have permission to log in to that host.

• The machine cannot reach the authentication server or directory server that

contains that user's information.

• There may be problems with the X Window System authenticating this particular

user, especially if the user's home has been used with another Linux distribution

prior to installing the current one.
