• 11:42 DWM and Dmenu Installation: DWM (Dynamic Window Manager) and Dmenu are cloned from suckless.org using git clone and then installed using make && make install in their respective directories.
• 14:16 Initial DWM Setup: A .xinitrc file is created with exec /usr/local/bin/dwm to launch DWM when startx is executed.
• 15:12 Display Manager Introduction: The video moves on to installing a display manager, specifically LightDM, to provide a graphical login screen and simplify starting the desktop environment.
• 17:49 LightDM Installation: gui-libs/display-manager-init and x11-misc/lightdm are emerged to install the necessary LightDM components.
• 19:02 LightDM Configuration: The /etc/config.d/display-manager file is edited to set DISPLAYMANAGER="lightdm".
