6 nodm - X display manager for automatic logins
7
9 nodm [options]
10
12 nodm is a minimal display manager that simply logs in as a given user
13 and starts an X session, without asking for username or password.
14
15 On a normal computer, using nodm is a big security issue because it
16 would give anyone access to the computer.
17
18 However, there are cases where automatic login is needed: for example
19 in an embedded system such as a mobile phone, or in a kiosk setup, or
20 in a control panel for industrial machinery. For those cases, nodm is
21 simple to setup, lightweight, and it should do exactly the right thing.
