GEN000000-LNX00380 - An X server must have none of the following options enabled: -ac, -core (except for debugging purposes), or -nolock - '-ac'

Information

These options will detract from the security of the Xwindows system.

Solution

Disable the unwanted options:
Procedure:
For gdm:
Remove the -ac, -core and -nolock options by creating a 'command' entry in the /etc/gdm/custom.conf file with the options removed.

For Xwindows started by xinit:
Create or modify the .xserverrc script in the user's home directory to remove the -ac, -core and -nolock options from the exec /usr/bin/X command.
