$ gedit ~/.warsow/basewsw/config.cfg2) Search for "vid_customheight" and "vid_customwidth" and change the value to one of the resolution (higher than 800x600) that works with your monitor
seta vid_customheight "768"
seta vid_customwidth "1024"
Same problem happen to me with Extreme Tux Racer.$ gedit ~/.etracer/options2) Search for "y_resolution" and "x_resolution" and change the value to one of the resolution (higher than 800x600) that works with your monitor
set x_resolution 1280

6) Mount the partition. Change xxx into your partition number (Since I've already boot into my Linux and /dev/sda4 is mounted to /boot, I'm not sure whether this step is still required)$ sudo mount /dev/xxx /mnt7) Install GRUB to the MBR
$ sudo grub-install --root-directory=/mnt hd0If step #6 is not required, I'm assuming the command would be (I need to check this with Ady)
$ sudo grub-install --root-directory=/ hd08) I didn't make any changes to my existing /boot/grub/menu.lst file

Installation modes
$ sudo aptitude updateb) Update the system
$ sudo aptitude upgradec) Install window manager, since the FVWM-Crystal version in Ubuntu repo is 3.0.4, you can upgrade to latest version (3.0.6 at the time of writing) by downloading the tarballs and install
$ sudo aptitude install xorg fvwm-crystal linux-headers-`uname -r` build-essential msttcorefonts tango-icon-theme menu
$ wget http://download.gna.org/fvwm-crystal/3.0.6/fvwm-crystal-3.0.6.tar.gz
$ tar -xvzf fvwm-crystal-3.0.6-tar.gz
$ cd fvwm-crystal-3.0.6
$ sudo make install
d) Make sure X knows to trigger FVWM-Crystal when it starts up$ nano -w ~/.xinitrce) Type the text below to the file and press Ctrl+O and Ctrl+X to save and exit
$ exec fvwm-crystalf) Start your window manager
$ startxg) Once you're in, right click the desktop and X terminal will appear. Now we need to install some of the basic tools to the system. There's a lot of choices for file manager, my favorite are pcmanfm, thunar or nautilus
$ sudo aptitude install gdm xfce4-terminal nautilus synaptic update-manager ubuntu-gdm-themes usplash usplash-theme-ubuntu gnome-media file-rollerh) Then install other applications
$ sudo apt-get install firefox pidgin gedit abiword gnumeric rar unrar lha firestarter frozen-bubble gimp inkscape exaile vlc totem kaffeinei) And the most important part is multimedia codecs
$ sudo apt-get install gstreamer0.10-plugins-ugly-multiverse gstreamer0.10-plugins-bad-multiverse gstreamer0.10-plugins-bad gstreamer0.10-plugins-ugly gstreamer0.10-ffmpeg libxine1-ffmpeg libdvdread3 w32codecs flashplugin-nonfreeThere you are, a stripped down version of Ubuntu with lite windows manager :)

$ sudo /etc/init.d/gdm start
$ wget ftp://ftp.idsoftware.com/idstuff/quake3/linux/linuxq3ademo-1.11-6.x86.gz.sh2) Allow the file to be executed as a program
$ sudo chmod 755 linuxq3ademo-1.11-6.x86.gz.sh3) Post Dapper, dash is a default shell for Ubuntu. We need to change this to bash before installing the game. To do so, open terminal and at home folder execute the following command and select <No>.
$ sudo dpkg-reconfigure dash4) Execute the installer
$ ./linuxq3ademo-1.11-6.x86.gz.sh -target ~/programs/q3-temp5) If the installer is returning an error like below

6) Simply execute the command below and re-executing the installer
$ export _POSIX2_VERSION=1992097) During the installation, if there's a permission denied error on the targeted bin folder, simply create the folder manually using terminal or nautilus and proceed with the installation
/
/home
/your-username
/programs
/q3-demo
/bin
8) Launch the game
$ programs/q3-demo/q3demo.x869) If there's no sound, check sound initialization section from the output, if it's the same as below
------- sound initialization -------
/dev/dsp: Broken pipe
Could not toggle.
10) Edit bootmisc.sh
$ sudo gedit /etc/init.d/bootmisc.shFrom

11) Restart your machine (there should be a way to restart the service alone)$ programs/q3-demo/q3demo.x86 +set s_musicvolume -113) Remove installer temp folder
$ rm -r programs/q3-temp14) Change back shell from bash to dash by selecting <Yes>
$ sudo dpkg-reconfigure dashNote:

Update (03/06/2010)$ linux32 ./linuxq3ademo-1.11-6.x86.gz.sh -target ~/programs/q3-tempTested on Ubuntu 10.04 Lucid Lynx 64 bit.
$ sudo echo "q3demo.x86_64 0 0 direct" > /proc/asound/card0/pcm0p/ossIf you're getting this error
bash: /proc/asound/card0/pcm0p/oss: Permission deniedJust set the correct permission to the file and you're done. Tested on Ubuntu 10.04 Lucid Lynx 64 bit.
$ sudo apt-get install ia32-libsNow there's one more issue left. The sound. /proc/asound/card0/pcm0p/oss file seems missing.
$ sudo apt-get install g++ zlib1g-dev libsdl1.2-dev libjpeg62-dev nasm tar bzip2 libgtk2.0-dev cmake build-essential2) Get ZDoom sources from ZDoom Downloads Page or Subversion Repository (recommended).
$ sudo apt-get install subversion4) Create programs folder in your home directory (optional. this is for newbies only)
$ mkdir programs cd programs5) To obtain the latest version from the SVN, use the following command
$ svn checkout http://mancubus.net/svn/hosted/zdoom/zdoom/trunk6) Download FMod package and save it in programs folder created earlier or you can execute the following command.
$ wget http://www.fmod.org/index.php/release/version/fmodapi42608linux.tar.gz7) Unzip FMod package by using right click and extract here or the following command
$ tar -xvzf fmodapi42608linux.tar.gz8) Now you will have a folder with a structure like shown below
/
/home
/your-username
/programs
/fmodapi42608linux
/trunk
9) Rename folder fmodapi42608linux to fmod-4.26.08$ cd zdoom12) Invoke CMake to parse the ZDoom source and get ready for compiling
$ cmake -DFMOD_INCLUDE_DIR=~/programs/fmod-4.26.08/api/inc -DFMOD_LIBRARY=~/programs/fmod-4.26.08/api/lib/libfmodex-4.26.08.so13) Compile the code
$ make14) If all goes well, an executable zdoom and the zdoom.pk3 file will be generated in the directory. To start zdoom, use the following command
$ ./zdoom15) ZDoom will try to search for the IWAD files from $HOME/.zdoom or /usr/local/share. If you have an IWAD files in a different location, simply edit zdoom.ini located in ~/.zdoom by adding the path in [IWADSearch.Directories] section
# These are the directories to automatically search for IWADs.
# Each directory should be on a separate line, preceded by Path=
[IWADSearch.Directories]
Path=.
Path=$DOOMWADDIR
Path=~/.zdoom
Path=~/programs/id-classic-wads/
