Xonotic FAQs

How do I install Xonotic?

There is no need to install Xonotic! The zip file you downloaded from the homepage has everything. All binaries to run the game on Linux, Windows and OSX are inside of it. Just unzip the archive and run the appropriate executable for your OS.

For example, on Windows or OSX you can start the game by double-clicking the Xonotic logo. On Linux you can run xonotic-linux-glx.sh or xonotic-linux-sdl.sh - whichever one works better on your hardware.

Is there a Debian package available?

There is an unofficial package available on playdeb.net. Unfortunately, Xonotic is not in the Debian repositories yet. You can check the status of the bug report here. If you can help us expedite this process, please contact us!

How and why did you choose the name?

Brainstorming of the name started on day 1 of our discussions, and the process took about 4-5 days.

We had about 30 key community members onboard at the time of the name choosing. We all submitted ideas and voted on the best names. Some names were ruled out because of domain availability and name-conflicts with other software projects or companies in the software industry. Some names were ruled out because of how common they were in Google searches. Xonotic was a unique name with an available .com/.net/.org and google search results were almost none.

How do you pronounce the name Xonotic?

There are two pronunciations, depending on where you live.

US people are more likely to pronounce it : zone + otic
European people are more likely to pronounce it : kso + notic

How and why did you choose the logo?

The logo design process took about a week, with a handful of people contributing designs, and constantly adjusting those designs based on feedback.

The phoenix image of the logo obviously refers to the concept of “rising from the ashes”.

Another aspect of the logo is the center ring, which has some similarities to the Quake logo; it has a fatter bottom edge and thinner top edge, though quake didn’t use a complete ring shape. This is intended as a pay of respect to the Quake origins of the game, as the Darkplaces engine was originally based on the Quake 1 engine.

What is going to be different between Xonotic and the current Nexuiz GPL?

  • A more unified and consistent art direction
  • New player models and animations
  • New set of default maps, some of them will get a makeover
  • New sounds and music
  • New stronger bot AI
  • Low quality textures will be dropped and replaced with higher quality ones
  • Some weapon models may be changed
  • More frequent releases
  • Global player stats tracking system, supporting anonymous player as well
  • So much more …

Troubleshooting

When I start Xonotic all I see is a black screen or a black screen with some checkered squares

This happens when the engine can’t load the data*.pk3 file or has trouble to initialize OpenGL. The reasons could be:

  • You unpacked the zip file without folder names, see How do I install Xonotic?
  • On Linux: the current directory is not your Xonotic/ folder.
  • On Mac: you tried to extract and move the files from a Xonotic update and it deleted the old files. When using the mac GUI please be sure to move only the files not the folders as that will delete the old files or use the mv console command which will not delete the old files.
  • The engine could not initialize OpenGL. Please install the latest drivers for your graphic card. You will probably find one for your card there: intel ati nvidia.
  • Your download might be corrupted, please download Xonotic again.

Using Linux I only see the map but no players and items

This happens when the engine has trouble initializing OpenGL. The reasons could be:

  • The engine could not initialize OpenGL. Please install the latest drivers for your graphic card. You will probably find one for your card there: intel ati nvidia
  • You do not have permissions needed for 3d acceleration. Usually you need to add yourself to the group video, you can do that via console as root like this: usermod -a -G video YOURUSERNAME. You need to logoff/in afterwards.

When I start Xonotic my screen is flickering

This is known to happen on Windows with Intel graphic chips and is a bug in the graphics drivers. A workaround is to set Flip-Policiy to blit. Open the control panel, there should be an icon called Intel® GMA driver (or something like that), double click it. Click on 3D Settings to find the screen with those settings.

How can I speed up my frame rate?

You can choose predefined performance settings in the Settings / Video menu or you can enable/disable single features. The greatest performance boost can be achieved by turning off dynamic lights and shadows in the Settings / Effects menu. Bloom is also quite resource intensive. Other fps boots include disabling Deluxemapping and Coronas. On older graphics cards or on-board/notebook chips with little video ram you can try to lower the texture quality in the Settings / Video menu. Some graphic cards (mostly ATI or quite old cards) run A LOT faster if you disable the Vertex Buffer Objects in the Settings / Video menu. An other thing that can greatly help on such cards is to disable the OpenGL 2.0 Shaders. Having that option enabled is faster on most cards however, that is why both are active by default.

If none of that helps, you can try compiling Xonotic from source.

The sound is broken, it crackles and stutters

Try run xonotic-sdl.exe instead of xonotic.exe (on Windows). Adding the command line options -sndspeed 48000 and/or -sndstereo can also help on some systems (on Linux, Mac, Windows).

Mouse is too slow and sensitivity is at top (on Mac / Linux)

Mac: The default mouse acceleration on Mac is very high and strange. The Xonotic defaults work fine with it but some mouse drivers seem to ‘correct’ the mouse acceleration and conflict with the Xonotic defaults. Try to disable the option Turn off OS mouse acceleration in the Settings / Input menu. Or the same via console: apple_mouse_noaccel 0; vid_restart (How do I open the console?)

Linux: A similar problem can arise on Linux. It’s also Turn off OS mouse acceleration in the Settings / Input menu but the console command is different: vid_dga 0; vid_restart (How do I open the console?)

I can’t switch to 32 bit color depth (on Windows)

Check if your desktop color depth is set to 32 bits per pixel. If it’s just set to 16, Xonotic can’t switch to 32 bit mode.

When I join a server or after a map change I see nothing but a black screen, but I can still move and shoot

This is probably because you don’t have the map that’s running on the server or it didn’t download correctly. Try clearing your dlcache (in ~/.xonotic/data/dlcache).

For Linux users: you need to have libcurl installed, otherwise you won’t be able to download any maps. libcurl should be available in any Linux distribution, just search for “libcurl” and install it in your distribution’s package manager.

How to report crashes and bugs

Use our issue tracker on Gitlab.

If you want to investigate further:

On Linux: In a xterm, cd into your Xonotic installation directory, start catchsegv ./xonotic-linux-686-sdl -condebug -developer > crash.txt 2>&1 and give the file crash.txt to the developers. Note that you can also use ./xonotic-linux-686-glx or if you have a 64bit system ./xonotic-linux-x86_64-sdl and ./xonotic-linux-x86_64-glx

On Windows: Click Start->Run, and enter drwtsn32, click Ok in the next window, run Xonotic and wait for the crash. Then go to C:\Documents and Settings\All Users\Application Data\Microsoft\Dr Watson there should be a file called “drwtsn32.log”, give that file along with the engine’s build date to the developers. You’ll see that date when you open the ingame console (How do I open the console?). Note that some folders of that path may be hidden or have a translated name if you’re using a non-english windows.

Where can I get more help?

Visit the official Xonotic forum, there is a support and bug report area. Or get on IRC to chat with others or ask for help. There is the normal users channel (irc://irc.quakenet.org/xonotic) and the developers channel (irc://irc.freenode.net/xonotic)

General questions

How do I install new maps?

Maps usually ship as .pk3 file. All you have to do is to copy this file to the Xonotic/data/ (on Linux, Mac, Windows) OR ~/.xonotic/data/ (on Linux, Mac) directory. Map packages that were downloaded from a server during playing end up in Xonotic/data/dlcache/ or ~/.xonotic/data/dlcache/ and are only used till you exit Xonotic. If you want to play them locally or use them to setup a server of your own you can “accept” the packages by moving it one level up - right next to your config.cfg.

An extensive list of maps is at xonotic.co

How can I place a shortcut to Xonotic on my Linux desktop?

Use the script xonotic-linux-sdl.sh or xonotic-linux-glx.sh instead of the binaries. The scripts will use the correct working directory,choose the right version (32 or 64 bit) and also allow you to start a extra X server.

How do I open the console?

Press [shift]+[escape]. To close it press [escape]. While playing ` or ^ will also open the console.

What console commands/variables are there?

An searchable list is available here, or you can search in-game using apropos in console (How do I open the console?).

How can I use colors in my nickname and messages?

Colors can be used in nicknames and chat messages via two ways: Either the simple way by typing ^ followed by a number between 0 and 9 or by typing ^x followed by three hexadecimal numbers (0-F) representing red, green and blue components of the color before the text. The second way allows for much more colors. For example if you type ^xF00message the text “message” will be displayed in red color. Simple examples:

code rgb code color
^0 ^x000 black
^1 ^xF00 red
^2 ^x0F0 green
^3 ^xFF0 yellow
^4 ^x00F blue
^5 ^x0FF cyan
^6 ^xF0F magenta
^7 ^xFFF white
^8 half-transparent black
^9 ^x888 grey
^x800 dark red
^x080 dark green
^x880 dark yellow
^x008 dark blue
^x088 dark cyan
^x808 dark magenta

How do I watch/record demos?

Demos are recordings of matches that you have played. To automatically record a demo each time you play enable the option Record demos while playing in the Multiplayer / Demos menu. Or if you just want to record some matches open the console and type rec before playing. That is before starting a game or connecting to a server. The demo file will then be stored in Xonotic/data/demos/.dem (on Windows) or ~/.xonotic/data/demos/.dem (on Linux, Mac). If you downloaded a demo, copy it to Xonotic/data/demos/.dem (on Linux, Mac, Windows) or ~/.xonotic/data/demos/.dem (on Linux, Mac). You might have to create this directory if you have never recorded a demo before. To watch demos you can choose a demo file in the Multiplayer / Demos and click the play button. Also you can watch demos typing ply in the console (How do I open the console?). You can list all your demo files by typing dem on the console.

Server setup

How do I start a server?

Use the Multiplayer / Create menu to start a listen server. You will always have to play yourself in a listen server. If you want to create a server without being forced to play yourself please take a look at the file readme.txt in the Xonotic/server/ directory where the dedicated server is explained.

Which ports do I have to open in firewall/forward from my router to run a server?

The default port is 26000 UDP. You can change that in the Multiplayer / Create menu or by starting Xonotic with the parameter -port or having a line port in the server config file. If you follow the tutorial mentioned above you do not need this command line argument as it will be done in the config file created for the server. To add the command line argument on Windows, create a new shortcut to xonotic.exe or xonotic-dedicated.exe and right click on it. Select properties and -port in the “Target:” line. Be sure that the “Start in:” line contains the full path to your Xonotic folder and click “OK”. The parameter will be used if you start Xonotic via that new shortcut.

Is there some kind of rcon?

Yes there is a QuakeWorld compatible rcon. To use it you must enter rcon_password in the server console or server config file. The Xonotic client has to set the same password in the same fashion. You can then issue commands with rcon if you are connected to the server or will have to set rcon_address or rcon_address : to point to the server. There are also external rcon tools but make sure you use a QW compatible rcon tool.

How can I kick people who are using special characters in their names?

Enter status at the server console. You will see a list of all players. In front of their names you will see a number (the player id). You can kick the player you don’t like with kick # (notice the space after #).

Nexuiz Related FAQs

What prompted the split from Nexuiz?

Lee Vermeulen, the Nexuiz project founder, decided to license the Nexuiz code (with LordHavoc licensing the Darkplaces engine) to a new game development company named Illfonic so that they could develop a closed-source version for the PS3. As part of this deal, IllFonic acquired the rights to use the name Nexuiz along with the domain nexuiz.com, and are under no obligation to contribute code back to the open-source Nexuiz project (and have stated that they have no intention of doing so).

When this was announced, the response from the Nexuiz community was overwhelming negative, even among the development team and main contributors. Vermeulen had not actively participated in the project for several years and all development had been done by the community. Most members have expressed a sense of betrayal and cited the project as an example of mushroom management. Vermeulen essentially cashed in on the hard work of others and sold the code, name and reputation that they had built up over years without him.

Despite attempts to reason with IllFonic, they have refused to change the name of their project to a derivative name even though they have directly stated that their “version” of Nexuiz is a completely different game. The hijacking of the Nexuiz project by its absentee founder and IllFonic made it clear that it had no future as it stood and thus the community left to found Xonotic.

It should also be noted that IllFonic’s code may be in violation of the GPL as most contributors to the Nexuiz codebase have not relicensed their work for inclusion in a closed-source project. This has been another source of outrage for many.

Update: The GPL concerns have been cleared up by a recent interview with LordHavoc.

Was a compromise attempted?

Yes, many in the Nexuiz community tried to reach a compromise, such as having Illfonic contribute some artwork and/or gamecode back to Nexuiz GPL and for them to use a derivative name for their project, e.g. “Nexuiz Reloaded”. Illfonic flatly refused all such suggestions. This, along with the clear stance that Alientrap has taken on this issue, made it clear that no compromise could be reached.

Update It has been clarified that, despite some of misleading wording in previous communication, Illfonic will be contributing some of the game code back to Nexuiz GPL, mainly having to do with bandwidth improvements and animation blending.

How will the management of Xonotic differ from Alientrap/Nexuiz GPL?

From the very start, we all discussed organizing the Xonotic Team with a handful of caretakers to make decisions on big/difficult issues for the game, and a committee underneath with community contributors who make decisions on most issues. The caretakers will also act to keep the project on track and maintain organization. All decisions will be made with input of the committee. The names of the caretakers are:

  • DivVerent [GER] : Lead developer
  • -z- [US] : Lead web developer, Server admin
  • Samual [US] : Developer, Server admin
  • tZork [SWE] : Developer, Server admin, Mapper, Modeler
  • mand1nga [ARG] : Developer
  • merlijn [HOL] : Developer, Server admin
  • Morphed [POL] : Modeler, Developer

Do you despise Vermeulen, LordHavoc or Illfonic?

No! Without the past work of Vermeulen and LordHavoc, we would not have the game that we enjoy today. We wish them the best of luck in their endeavors. We hope Illfonic’s Nexuiz on PS3 is successful. We simply have a difference of opinion on project management and the result is going to be very positive; We’re forming a game project that matches what we wanted out of Nexuiz all along.
