Installing Ubuntu
Versions 8.04 LTS (Hardy Heron) 9.04 (Jaunty Jackalope) 10.04 LTS (Lucid Lynx)
Scheduled release April 29, 2010 Either 32 or 64 bit We are using 8.04 LTS 32 bit
Installing Ubuntu
Can be installed in Windows Can be installed from a flash drive or CD Only 1 monitor can be connected during
install
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
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
