Some Implementations
The X Window System supplies XDM as its standard display manager.
Programmers have developed other X display managers, both commercial and free, offering additional functionality over the basic display management:
- Qingy ultralight and very configurable graphical login independent on X Window (uses DirectFB)
- GDM (GNOME)
- KDM (provided by KDE) allows the user to graphically select a window manager or desktop environment in the login screen
- XDM, the default X Window System Display Manager
- XDM-OPTIONS for xdm. Easy full install, Xhost Phonebook, X Login, X Desktop Chooser, menu-reconfig, repair utils.
- LDM, the (remote) Display Manager of the Linux Terminal Server Project
- dtlogin (shipped with CDE)
- scologin (provided by SCO Open Desktop) also checks for expired passwords and performs some administrative tasks
- WINGs Display Manager (using the WINGs widget-set used in Window Maker)
- entranced/entrance (employs the architecture used in Enlightenment v.17, on hiatus since 2005)
- LXDM, a lightweight display manager, part of LXDE, cross-desktop, fully themeable
- SLiM, an independent login manager.
- CDM, an ultralight Console Display Manager for Unix
- xlogin, X Window login with separate XDMCP server
- Enter Lightweight graphical login manager
- Orthos, another lightweight solution with very configurable animated themes that use OpenGL only
- nodm, auto-login display manager for systems like kiosks, appliances and mobile phones
- LightDM, a lightweight, modular, cross-desktop, fully themeable desktop display manager
On some Unix distributions, the default display manager is selected in file $PREFIX/etc/X11/default-display-manager.
