The 'beta' status means that although we're still smoothing-out a few rough edges, this version of the client is functionally complete and should work quite well 'out of the box'. We encourage you to try it out and let us know of its compatibility with your system. Be aware that although this is a 'beta' client, it connects to the main Second Life world and changes you make there are permanent. Please enjoy! 2. SYSTEM REQUIREMENTS -=-=-=-=-=-=-=-=-=-=-= Minimum requirements: * Internet Connection: Cable or DSL * Computer Processor: 800MHz Pentium III or Athlon or better (recommended: 1.5GHz or more) * Computer Memory: 2048MB (ie, 2GB) * Linux Operating System: A reasonably modern 32-bit Linux environment is required. If you are running a 64-bit Linux distribution then you will need its 32-bit compatibility environment installed, but this configuration is not currently supported. * PulseAudio or ALSA Linux system sound software. A recent PulseAudio is the recommended configuration; see README-linux-voice.txt for more information. * Video/Graphics Card: o nVidia GeForce 2, GeForce 4mx, or better (recommend one of the following: 6700, 6800, 7600, 7800, 7900, 8400, 8500, 8600, 8800, Go 7400, Go 7600, Go 7800, Go 7900, +) o OR ATI Radeon 8500, 9250, or better (nVidia cards are recommended for the Linux client) **NOTE**: Firestorm absolutely requires you to have recent, correctly- configured OpenGL 3D drivers for your hardware - the graphics drivers that came with your operating system may not be good enough! See the TROUBLESHOOTING section if you encounter problems starting Firestorm. For a more comfortable experience, the RECOMMENDED hardware for the Second Life Linux client is very similar to that for Windows, as detailed at: 3. INSTALLING & RUNNING -=-=-=-=-=-=-=-=-=-=-=- The Firestorm Linux client can entirely run from the directory you have unpacked it into - no installation step is required. If you wish to perform a separate installation step anyway, you may run './install.sh' Run './firestorm' from the installation directory to start Firestorm. For in-world MOVIE and MUSIC PLAYBACK, you will need (32-bit) GStreamer 0.10 installed on your system. This is optional - it is not required for general client functionality. If you have GStreamer 0.10 installed, the selection of in-world movies you can successfully play will depend on the GStreamer plugins you have; if you cannot play a certain in-world movie then you are probably missing the appropriate GStreamer plugin on your system - you may be able to install it (see TROUBLESHOOTING). User data is stored in the hidden directory ~/.firestorm by default; you may override this location with the FIRESTORM_USER_DIR, or FIRESTORM_X64_USER_DIR if using the 64 bit version, environment variable if you wish. 4. KNOWN ISSUES -=-=-=-=-=-=-=- * No significant known issues at this time. 5. TROUBLESHOOTING -=-=-=-=-=-=-=-=-= The client prints a lot of diagnostic information to the console it was run from. Most of this is also replicated in ~/.firestorm/logs/Firestorm.log - this is helpful to read when troubleshooting, especially 'WARNING' and 'ERROR' lines. VOICE PROBLEMS? See the separate README-linux-voice.txt file for Voice troubleshooting information. SPACENAVIGATOR OR JOYSTICK PROBLEMS? See the separate README-linux-joystick.txt file for configuration information. PROBLEM 1:- Firestorm fails to start up, with a warning on the console like: 'Error creating window.' or 'Unable to create window, be sure screen is set at 32-bit color' or 'SDL: Couldn't find matching GLX visual.' SOLUTION:- Usually this indicates that your graphics card does not meet the minimum requirements, or that your system's OpenGL 3D graphics driver is not updated and configured correctly. If you believe that your graphics card DOES meet the minimum requirements then you likely need to install the official so-called 'non-free' nVidia or ATI (fglrx) graphics drivers; we suggest one of the following options: * Consult your Linux distribution's documentation for installing these official drivers. For example, Ubuntu provides documentation here: * If your distribution does not make it easy, then you can download the required Linux drivers straight from your graphics card manufacturer: - PROBLEM 2:- My whole system seems to hang when running Firestorm. SOLUTION:- This is typically a hardware/driver issue. The first thing to do is to check that you have the most recent official drivers for your graphics card (see PROBLEM 1). SOLUTION:- Some residents with ATI cards have reported that running 'sudo aticonfig --locked-userpages=off' before running Firestorm solves their stability issues. SOLUTION:- As a last resort, you can disable most of Firestorm's advanced graphics features by editing the 'firestorm' script and removing the '#' from the line which reads '#export LL_GL_NOEXT=x' PROBLEM 3:- After I minimize the Firestorm window, it's just blank when it comes back. SOLUTION:- Some Linux desktop 'Visual Effects' features are incompatible with Firestorm. One reported solution is to use your desktop configuration program to disable such effects. For example, on Ubuntu 7.10, use the desktop toolbar menu to select System -> Preferences -> Appearance, then change 'Visual Effects' to 'None'. PROBLEM 4:- Music and sound effects are silent or very stuttery. SOLUTION:- The most common solution is to ensure that you have the 'esd' program (part of the 'esound' package) installed and running before you start Firestorm. Users of Ubuntu (and some other) Linux systems can simply run the following to install and configure 'esound': sudo apt-get install esound For others, simply running 'esd&' from a command-line should get it running. PROBLEM 5:- Using the 'Alt' key to control the camera doesn't work or just moves the Firestorm window. SOLUTION:- Some window managers eat the Alt key for their own purposes; you can configure your window manager to use a different key instead (for example, the 'Windows' key!) which will allow the Alt key to function properly with mouse actions in Firestorm and other applications. PROBLEM 6:- In-world movie, music, or Flash playback doesn't work for me. SOLUTION:- You need to have a working installation of GStreamer 0.10; this is usually an optional package for most versions of Linux. If you have installed GStreamer 0.10 and you can play some music/movies but not others then you need to install a wider selection of GStreamer plugins, either from your vendor (i.e. the 'Ugly' plugins) or an appropriate third party. For Flash playback, you need to have Flash 10 installed for your normal web browser (for example, Firefox). PulseAudio is required for Flash volume control / muting to fully function inside Firestorm. 6. ADVANCED TROUBLESHOOTING -=-=-=-=-=-=-=-=-=-=-=-=-=- The 'firestorm' script which launches Firestorm contains some configuration options for advanced troubleshooters. * AUDIO - Edit the 'secondlife' script and you will see these audio options: LL_BAD_OPENAL_DRIVER, LL_BAD_FMODSTUDIO_DRIVER. Firestorm tries to use OpenAL, FMODSTUDIO (PULSEAUDIO, ALSA) audio drivers in this order; you may uncomment the corresponding LL_BAD_* option to skip an audio driver which you believe may be causing you trouble. * OPENGL - For advanced troubleshooters, the LL_GL_BLACKLIST option lets you disable specific GL extensions, each of which is represented by a letter ("a"-"o"). If you can narrow down a stability problem on your system to just one or two GL extensions then please post details of your hardware (and drivers) to the Linux Client Testers forum (see link below) along with the minimal LL_GL_BLACKLIST which solves your problems. This will help us to improve stability for your hardware while minimally impacting performance. LL_GL_BASICEXT and LL_GL_NOEXT should be commented-out for this to be useful. 7. OBTAINING AND WORKING WITH THE CLIENT SOURCE CODE -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= We're pleased to have released Firestorm client's source code under an Open Source license compatible with the 'LGPL'. 8. GETTING MORE HELP AND REPORTING PROBLEMS -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- For general help and support with Firestorm: In-world discussion: Main support: Join one of our in-world support groups. There is also a 'Linux Client Users' group inside Second Life which is free to join. You can find it by pressing the 'Search' button at the bottom of the window and then selecting the 'Groups' tab and searching for 'Linux'. This group is useful for discussing Linux issues with fellow Linux client users who are online. The Firestorm Issue Tracker: This is the right place for finding known issues and reporting new bugs in all Firestorm releases if you find that the Troubleshooting section in this file hasn't helped.
