The ArchLinux Workstations are themed with either the ACM Logo or LUG logo. They are set to alternate between workstations. | 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 ====== | + | Install themes with this command and follow the post install instructions |
+ | <code|bash> | ||
+ | pacman -S acm-lug-lxdm-themes | ||
+ | </code> | ||
- | This is setup by two files: | + | Unpack {{:acm-themes.tar.gz|this archive with the ACM and LUG themes}} into /usr/share/lxdm/themes |
- | * /etc/lxdm/PreLogin | + | This is setup by several files: |

+ | * /etc/lxdm/LoginReady | ||
+ | * /etc/lxdm/PreLogin (unused) | ||

- | ** 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. | ||
