The Terminal

Common Terminal Commands cd: change directory . (period): refers to the current directory .. (double period): refers to the parent directory ls: list directory contents man: see the manual for a command (‘q’ to exit) mv and cp: move or copy a file rm: remove (delete) a file mkdir and rmdir: make and remove a directory chown and chmod: change file owner and

permissions (requires ownership or root access) sudo: run a command as the root user

Common Terminal Commands | (“pipe”): Send the output of one command as

the input to another command > : Send the output of a command to a file & : Run a command in the background grep: searches for patterns within text ps: show all running processes kill: end execution of a running process ssh: connect and execute commands on a

remote computer less: show the contents of a text file, one page

at a time gedit, nano, vim: text editors (gedit has a GUI)

Changing Permissions

ls –l shows files, permissions, and owners rwxr-xr-- haynieti somefile.txt

Think in terms of bits First 3 bits represent file owner (111=7) Second 3 bits represent group (101=5) Final 3 bits represent everyone else (100=4)

To achieve these permissions, you would type: chmod 754 somefile.txt

Installing MDM

First we need to allow permissions for the configuration files

> sudo bash

> chmod 777 /etc/X11> chmod 777 /etc/X11/xorg.conf

Installing MDM

Use the terminal to install repositories Repositories contain MDM installation files Use the command “apt-get”

Installing MDM

> gettext xserver-xephyr rccconf> git-clone

http://git.c3sl.ufpr.br/pub/scm/multiseat/mdm.git

> cd mdm/mdm> make> make install> cd ..

Installing MDM

> cd extra-modes/xephyr-gdm> make> make DESTDIR=/install> cd ../ ../> cd dependencies> apt-get build-dep libx11-6

Installing MDM

When using an Nvidia graphics card, the following patches are needed: discover-devices mdm-bin mdm-start-seat

Installing MDM

The xorg.conf file is for the display settings in GDM

Copy the xorg.conf file into the MDM folder and rename it xorg.conf.mdm We now have a display configuration file for

MDM

Installing MDM

In order to change MDM files we need to change permissions Chmod 777 /../../file name

xorg.conf.mdm

xorg.conf.mdm is MDM’s main configuration file

Allows computer to recognize ‘seats’

xorg.conf.mdm

xorg.conf.mdm

Other MDM files

mdm-bin

Starting MDM

From the terminal: /etc/init.d/gdm start /etc/init.d/mdm start

At this point, MDM is started and each screen prompts the user to register a keyboard/mouse

Log Files

The overall MDM log file:

Log Files

Each seat also has it’s own log file
