Verify the options of the running Xwindows server are correct.
Procedure:
Get the running xserver information
# ps -ef |grep X
If the response contains /usr/bin/Xorg:0
/usr/bin/Xorg:0 -br -audit 0 -auth /var/gdm/:0.Xauth -nolisten tcp vt7
this is indicative of Xorg starting through gdm. This is the default on this version of the operating system.
Examine the Xorg line:
If the "-auth" option is missing this would be a finding.
If the "-audit" option is missing or not set to 4, this is a finding.
If the "-s" option is missing or greater than 15, this is a finding.
If the response to the grep contains X:0
/usr/bin/X:0
this indicates the X server was started with the xinit command with no associated .xserverrc in the home directory of the user. No options are selected by default. This is a finding.
Otherwise if there are options on the X:0 line:
If the "-auth" option is missing this is a finding
If the "-audit" option is missing or not set to 4, this is a finding.
If the "-s" option is missing or greater than 15, this is a finding.
Enable the following options: -audit (at level 4), -auth and -s with 15 minutes as the timeout value.
Procedure for gdm:
Edit /etc/gdm/custom.conf and add the following:
[server-Standard]
name=Standard server
command=/usr/bin/Xorg -br -audit 4 -s 15
chooser=false
handled=true
flexible=true
priority=0
Procedure for xinit:
Edit or create a .xserverrc file in the user's home directory containing the startup script for xinit.
This script must have an exec line with at least these options:
exec /usr/bin/X -audit 4 -s 15 -auth <Xauth file> &
The <Xauth file> is created using the "xauth" command and is customarily located in the user's home directory with the name ".Xauthority".
