The GDM daemon is configured using the
|
|
<filename>/etc/gdm/custom.conf</filename> file.
|
|
Default values are stored in GSettings in the
|
|
<filename>gdm.schemas</filename> file. It is recommended that end-users
|
|
modify the <filename>/etc/gdm/custom.conf</filename> file
|
|
because the schemas file may be overwritten when the user updates their
|
|
system to have a newer version of GDM.
