+====== LXDM Login Theming Setup ======
 ====== Introduction ======
 The ArchLinux Workstations are themed with either the ACM Logo or LUG logo.  They are set to alternate between workstations.
-I(clee231)(Chase Lee) have written a script to determine and switch the logos based on hostname.
+====== Setup ======
-Currently, the script is setup to run once before logging in the user as root. This means that there needs to be at least one login for the script to run.
+<WRAP center round info 60%>
+Setup the [[linux:acm_custom_repo|ACM custom repo]] on the workstation first
+</WRAP>
-====== Setup ======
+Install themes with this command and follow the post install instructions
+<code|bash>
+pacman -S acm-lug-lxdm-themes
+</code>
+Unpack {{:acm-themes.tar.gz|this archive with the ACM and LUG themes}} into /usr/share/lxdm/themes
-This is setup by two files:
+This is setup by several files:
-  * /etc/lxdm/PreLogin
+  * /etc/lxdm/LoginReady
+  * /etc/lxdm/PreLogin (unused)

+  * /etc/lxdm/PreReboot (unused)
+  * /etc/lxdm/PreShutdown (unused)
+  * /etc/lxdm/lxdm.conf
   * /etc/lxdm/SetLogo
-** PreLogin ** - This calls the SetLogo script. Executed by LXDM as root.
+The directory also contains the Xsession file, which should not be edited manually
-** SetLogo ** - Contains a set of all six workstation hostnames, and detects which theme to use.
+** LoginReady ** - This is executed as root when LXDM is ready to show the screen.
+** PreLogin ** - Executed by LXDM as root.
+** SetLogo ** - Contains the sed regex for the link and IP, the 'even' and 'odd' themes settings, and detects which theme to use.
