| - | ====== 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. | ||
| - | |||
| - | ====== Setup ====== | ||
| - | |||
| - | <WRAP center round info 60%> | ||

| - | |||
| - | 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 several files: | ||
| - | |||
| - | * /etc/lxdm/LoginReady | ||
| - | * /etc/lxdm/PreLogin (unused) | ||
| - | * /etc/lxdm/PostLogin | ||
| - | * /etc/lxdm/PostLogout | ||

| - | * /etc/lxdm/PreShutdown (unused) | ||
| - | * /etc/lxdm/lxdm.conf | ||
| - | * /etc/lxdm/SetLogo | ||
| - | |||
| - | The directory also contains the Xsession file, which should not be edited manually | ||
| - | |||
| - | ** 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. | ||
