The Classic PC Doom game is a masterwork of game design. It is a first-person shooter that was an amazing revelation when it was released in 1993.
Install Doom on Linux
Type this command to install Doom and all required IWAD files easily.
jason@jason-desktop:~$ sudo apt-get install chocolate-doom doom-wad-shareware prboom-plus freedoom |
The Doom IWADS, freedoom.wad, doom1.wad live in the /usr/share/games/doom folder. If you own a copy of Doom or Doom2, copy the doom.wad and doom2.wad into this folder and then they will be accessible to prboom and chocolate-doom.
flynn@ubuntu:~/Documents$ ls /usr/share/games/doom/ doom1.wad freedoom.wad prboom.wad |
Prboom Plus is an enhanced version of Prboom with extra features. The Prboom+ source port has many useful features for recording demos and many features that benefit all Doomers in general. Install it on Ubuntu this way.
jason@jason-desktop:~$ sudo apt-get install prboom-plus |
This will also install Freedoom, giving the player a full IWAD with 30 maps to slaughter through.
Gzdoom is another magnificent source port that allows a fun gaming experience with countless mods and wad files that use advanced engine features.
Download Gzdoom from this website.
This is a lot of fun to use when playing Russian Overkill.
You may also install this with a Debian package.
https://securitronlinux.com/battlefield/how-to-install-gzdoom-on-ubuntu-and-play-russian-overkill-easily/. Russian Overkill is a lot of fun and playing with Gzdoom gives the best experience.
To add the IWADS for the Gzdoom snap, copy them to this folder.
~/snap/gzdoom/current/.config/gzdoom |
Then the IWADS will be available in the game menu.
The old vanilla Doom executable would show a flashing floppy disk icon when there was disk activity. Do any modern source ports use this feature or is it a bit superfluous in these days of super-fast 7200 rpm SATA2 drives and computers with an I7 CPU? I miss that feature from the days of playing vanilla Doom on a 486 sx33 with 4MB of RAM. Those were the days, we could never have imagined that we would be playing Doom on our phones. Or on an Android tablet. The great game has come so far in these modern times with Gzdoom and Chocolate Doom we have a wide choice if we want either accelerated graphics and 3d models or just classic vanilla Doom gaming. The Chocolate Doom game has a game engine that closely replicates the behaviour of the vanilla Doom engine as closely as possible.
Set a custom resolution for prboom
To set a custom resolution for prboom; open the ~/.prboom/prboom.cfg
file with vim.tiny and change the video resolution to the values you desire. Below is an example. set the screen_width and screen_height to the proper resolution of your monitor.
# Video settings videomode "16bit" screen_width 1920 screen_height 1080 use_fullscreen 1 use_doublebuffer 1 translucency 1 tran_filter_pct 87 screenblocks 10 usegamma 2 uncapped_framerate 1 filter_wall 1 filter_floor 1 filter_sprite 1 filter_z 1 filter_patch 1 filter_threshold 49152 sprite_edges 0 patch_edges 0 |
This will fix the resolution of prboom. This is how I always fix it.
Install a map editor
Install a nice map editor for Linux and start making levels for Doom.
The Eureka map editor for Linux is a good way to make awesome maps for this old game.
http://eureka-editor.sourceforge.net/.
This is not too hard to use and would allow a user to make whatever they want.
The user manual is here: http://eureka-editor.sourceforge.net/?n=User.Index.
So get cracking and make a cool map today!
Install gzdoom by typing sudo apt install gzdoom
. This is a very good source port that supports mods like Ultimate Torment and Torture. And looks very good running on a good GPU. It also supports some build engine features like 3D floors and movable 3D floors using portals. As well as ACS scripting to create cool effects.
Home page: https://zdoom.org/index. I ran gzdoom while in a folder containing IWADS and it finds them and allows you to select which one to play with.
Install Ultimate Doom Builder on Linux
Download this archive: https://securitronlinux.com/doomstuff/doom-builder.tar.gz. This is Ultimate Doom Builder compiled on Linux. This does work very well. I compiled it on Ubuntu 24.04, but it also runs on Alma Linux 9.3. This is not the latest version, but it does work fine and can make amazing maps.
Set a custom resolution for Chocolate Doom
To set a custom resolution for Chocolate Doom, edit the chocolate-doom.cfg file and edit the following lines to set a custom window size.
fullscreen 0 video_display 0 aspect_ratio_correct 1 integer_scaling 0 vga_porch_flash 0 window_width 1440 window_height 1080 fullscreen_width 0 fullscreen_height 0 |
Doomsday source port on Linux
The Doomsday source port on Linux is a great way to play Doom on a Linux machine. This has a launcher that will show all available Doom and Hexen/Heretic IWADS and allows you to play them with a single click. This is great.
Put all your wads in a folder such as $HOME/Doom and then tell Doomsday where they are.
┏jcartwright@jcartwright-System-Version╼╸╸╸╸╸╸╾ ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━◉:~$ export DOOMWADDIR=/home/jcartwright/Doom |
This will define where the Doom wads are to any source port on Linux. Then they will appear in the launcher.
Crispy Doom is another very good Doom source port, this is just like vanilla Doom, but limits removing to avoid visplane overflows.
Install this very easily.

This is a magnificent Doom source port with which to play classic Doom.
Very old but useful Doom files
Here are some very useful and old Doom files.
These should be very interesting to a Classic Doom fan.

Extracting and viewing Sega 32X Doom assets on Windows easily
This program should compile and run on Linux, I have just not tried it yet. But it does work to extract patches and the colour map as well as sprites.
And yes it does compile fine on Linux.

I have added the fix that I always use when fixing the resolution.
OK, so you do all that. Then play freedoom and exit, now your display is stuck in 640×480 with no way out! The display control to change it is off the screen and you can’t get it back! You have to reboot to fail-safe mode to set it back up. X screens aren’t made to handle 640×480 the default for .prdoom. Need to include this problem and a fix in the instructions above.
