I would like to add a new session to the login screen (the thing where you select "Ubuntu, Ubuntu Classic, etc" to install a new GUI on. How can I do this?
উত্তর:
The list on the logon screen is populated from the desktop files in the folder /usr/share/xsessions
The format of these files are similar - here is the Unity-2D desktop file
[Desktop Entry]
Name=Ubuntu Classic (No effects)
Comment=This session logs you into GNOME with the traditional panel without any
graphical effect.
Exec=gnome-session --session=2d-gnome
TryExec=gnome-session
Icon=
Type=Application
X-Ubuntu-Gettext-Domain=gnome-session-2.0
All the files are root:root owned.
Creating or deleting desktop files in this folder creates or removes an entry in the drop-down list respectively.
