9 | =head1 DESCRIPTION |
---|
10 | |
---|
11 | B<gdm> is the equivalent of xdm(1x) or wdm(1x), but uses the GNOME |
---|
12 | libraries to provide a GNOME look-and-feel. It provides the GNOME |
---|
13 | equivalent of a "login:" prompt. |
---|
14 | |
---|
15 | B<gdm> reads F</etc/gdm/gdm.conf> for its configuration. For each |
---|
16 | local display, gdm starts an X server and runs gdmlogin(8x) on that |
---|
17 | display. The main gdm process also listens for XDMCP requests from |
---|
18 | remote displays. These requests can either be direct, causing B<gdm> |
---|
19 | to start a gdmlogin(8x) on the remote display, or indirect, causing |
---|
20 | a gdmchooser(8x) to be opened. |
---|
21 | |
---|
22 | When managing a display, B<gdm> attempts to execute |
---|
23 | F</etc/gdm/Init/>I<display>, or F</etc/gdm/Init/Default> if that does |
---|
24 | not exist. When a user logs in, B<gdm> first attempts |
---|
25 | F</etc/gdm/PreSession/>I<display> (or F</etc/gdm/PreSession/Default>), |
---|
26 | and then one of the sessions in F</etc/gdm/Sessions>. When the session |
---|
27 | has completed, B<gdm> attempts to run |
---|
28 | F</etc/gdm/PostSession/>I<display>, or |
---|
29 | F</etc/gdm/PostSession/>I<Default>. Of all these files, only the |
---|
30 | F</etc/gdm/Sessions> one is required to exist. |
---|
31 | |
---|
32 | B<gdm> maintains information about the displays it is managing in |
---|
33 | F</var/lib/gdm>. This includes xauth information, so this directory |
---|
34 | is not readable to normal users. |
---|
35 | |
---|
36 | B<gdm> uses PAM to perform authentication using the config file |
---|
37 | F</etc/pam.d/gdm>. |
