The Terminal
Common Terminal Commands


cd: change directory
. (period): refers to the current directory

mv and cp: move or copy a file
rm: remove (delete) a file

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

ssh: connect and execute commands on a remote

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
