== How do I install Unreal in Linux? ==
#REDIRECT [[Unreal v227 Manual/Frequently Asked Questions]]
First you need to download the latest patch, but due to legal limitations (I'm not officially allowed to use a Linux specific installer) you must rely on the windows .exe patch
Then there are 2 ways:
 
1. If you want to use Linux only, you need to run the installer from CD and then the patch with [http://www.winehq.org Wine] to install it.
2. Install it in Windows and copy the directory over.
 
'''After installing (or copying it over) you can run it native without Wine''' f.e. in console with ./UnrealLinux.bin (in the Unreal/System directory or create a shortcut to start it from somewhere else).
 
UCC is also existing and fully functional except font import.
So you can start a server like in Windows with "./UCCLinux.bin server ...". If you start it from console you can enter any command like in the windows version, but directly in the console window.
 
== On which distributions is Unreal 227 running on? ==
'''For the moment I have reports that it is running on:'''
 
OpenSuSE 11.0,11.1,11.2,11.3
 
Slackware 12.X, 13.0 (but maybe artsd needs to be killed if using OSS for sound or Unreal needs to be started up without sound with the -nosound option)
 
Archlinux (last update 18.05.2009)
 
'''Problems are reported on:'''
 
Ubuntu (not sure which release)
 
== On which graphic card is Unreal running on? ==
 
'''NVidia:'''
 
Currently all cards seem to run fine with NVidia drivers installed.
Tested and working with: GeForce 4 Ti4200, Geforce 5900XT, Geforce 8400M GS, Geforce 9800 GT, Geforce 9800 GTX, GTX260
 
'''ATI:'''
 
Should run fine, however no concrete reports yet.
 
'''Intel:'''
 
integrated Chipset like GM965 with Mesa works but there seem to be some problems with OpenGL (f.e. adjusting Brightness doesn't work in some cases).
 
== Unreal segfaults at startup ==
 
'''Currently the following reasons are known:'''<br />
<br />
A messed up ini:<br />
remove or rename UnrealLinux.ini and let Unreal create new one<br />
<br />
 
 
 
Sound Issues:<br />
Try to start Unreal with -nosound option to confirm. Then check the section [[Oldunreal_227_Linux_FAQ#Sound_issues]] for solutions.
 
On some distributions needed dependencies for libSDL are missing, so please make sure to have the packages "svgalib-bin", "libsvga", and "libsdl-gfx" installed.<br />
If your system doesn't provide all libraries, there is a package called linux_convenience_libs.7z in the Help (only 227g) folder which should contain all the necessary files.
 
 
 
If you get something like that:
 
  Processors / Cores 2
  XDM authorization key matches an existing client!Couldn't initialize SDL: Couldn't open X11 display
 
 
  History:
 
  Exiting due to error
 
Try make "xhost +"(without quotes) before launching Unreal.
 
OR
 
Delete System/libSDL-1.2.so*
 
 
Another reason for segfaults at startup could be that the requested fullscreen resolution is higher than your monitor supports (you switched your monitor maybe or took over the UnrealLinux.ini from another system).
 
== After deleting libSDL.so.0 Unreal shows me black screen! ==
 
Do not panic. Hit ~, type quit. Unreal will exit, but your image on screen can be corrupted, just restart your X and downgrade SDL to version 1.2.13
 
== How do I access Advanced Options? ==
There are no Advanced Options for Linux users. You need to edit the UnrealLinux.ini instead.
But all possible options are already in the file and commented with a semicolon (;). You just need to change the commented lines.
 
== I want to use the Unreal Gold/Unreal Tournament menu interface instead of this old one!  ==
 
Open your UnrealLinux.ini and change the following lines in section [Engine.Engine]:
 
<nowiki>Console=UBrowser.UBrowserConsole</nowiki>
 
<nowiki>;Console=UMenu.UnrealConsole</nowiki>
 
into
 
<nowiki>;Console=UBrowser.UBrowserConsole</nowiki>
 
<nowiki>Console=UMenu.UnrealConsole</nowiki>
 
 
== Is there no UED for Linux? ==
Old UED is built in visual basic and UED2 is completely based on Windows. A complete rebuild of UED2 in QT or GTK would be necessary to port it. So not planned at the moment. However, UED2 is running in wine and 227f's version does support OpenGL for the viewports, so it should be possible to run UED2 completely.
Reports are welcome.
 
[http://appdb.winehq.org/objectManager.php?sClass=version&iId=460 Wine AppDB entry]
 
== Does 227 need wine to run? ==
No, 227f and 227g are having a complete native port. Wine is not needed to run it.
But since there is no Linux installer yet with permission from EPIC, Wine is needed to install the base game and the patch itself. After installing it Wine is no longer needed and the game can be run with UnrealLinux.bin
 
== My system / distro / graphics card driver seems to have problems with OpenGL or graphics are messed up ==
 
Try SDLSoftDrv instead:
 
<nowiki>;GameRenderDevice=OpenGLDrv.OpenGLRenderDevice</nowiki>
 
<nowiki>GameRenderDevice=SDLSoftDrv.SDLSoftwareRenderDevice</nowiki>
 
<nowiki>;GameRenderDevice=SDLGLDrv.SDLGLRenderDevice</nowiki>
 
SDLGLDrv can be tried also, but its an old and not very advanced renderer. Its just left in there for testing purposes.
 
!!! To use it you need to add -NoForceSDLDrv at startup. !!!
 
Please note that SDLSoftDrv and SDLGLDrv are NOT supporting S3TC highres textures!
 
 
== Sound issues ==
 
If you have any problems, try first to change the sound output to OpenAL (or if you set it up first to OpenAL then try FMOD).
in Section
 
Engine.Engine] <br />
<nowiki>;AudioDevice=FMODAudioDrv.FMODAudioDevice</nowiki> <br />
<nowiki>AudioDevice=ALAudio.ALAudioSubsystem</nowiki> <br />
Default is FMOD. <br />
 
227 is offering OpenAL and FMOD for sound output.
227f uses OSS for output, in 227g there are specific options to chose between ALSA,OSS,ESD (and maybe more), the available devices can be seen in UnrealLinux.bin.log and set up accordingly in UnrealLinux.ini then.
 
If there is no sound or if it segfaults at startup then check if maybe a daemon like artsd is blocking the output at /dev/dsp. This should only happen with OSS, try using ALSA.
 
If your Unreal segfaults at startup because of sound you can set "ProbeDevicesOnly" in UnrealLinux.ini to determine the available devices in a failsafe way.
 
 
'''FMOD: Sound starts but stops after a few seconds playing'''
 
Lower number of channels.
 
OpenAL uses FMOD for music output and if using OSS it can be that OpenAL is blocking /dev/dsp for FMOD then. This seems to be system specific and the only recommendation is: if possible use ALSA.
 
 
'''I don't have EAX/EFX effects / the environment ambients like "Underwater etc" do not work!'''
 
Sorry, OpenAL Linux did not support EFX effects like in Windows in 227f.
227g is having an equal implementation.
However, OpenAL does not match exactly the echo/reverb model of the old previous versions, but it offers 112 ambient presets which are used for zones like "Underwaterzone", "Slimezone" etc. and some replacement for the echoes. So its way more functional, but if you want an exact matching reverb like in the first days of Unreal, you have to use FMOD.
