This is a BETA release of the Second Life client for Linux. 30The 'beta' status means that although we're still smoothing-out a few rough 31edges, this version of the client is functionally complete and should 32work quite well 'out of the box' for accessing Second Life. 33 34We encourage you to try it out and let us know of its compatibility 35with your system. Be aware that although this is a 'beta' client, it connects 36to the main Second Life world and changes you make there are permanent. 37 38You will have either obtained this client from secondlife.com (the official 39site) or from a third-party packager; if you encounter any problems then 40we recommend trying the latest official builds from secondlife.com which are 41updated often. 42 43Please enjoy! 44 45 462. SYSTEM REQUIREMENTS 47-=-=-=-=-=-=-=-=-=-=-= 48 49Minimum requirements: 50 * Internet Connection: Cable or DSL 51 * Computer Processor: 800MHz Pentium III or Athlon or better 52 (recommended: 1.5GHz or more) 53 * Computer Memory: 512MB (recommended: 768MB or more) 54 * Linux Operating System: A reasonably modern 32-bit Linux environment 55 is required. If you are running a 64-bit Linux distribution then 56 you will need its 32-bit compatibility environment installed, but 57 this configuration is not currently supported. 58 * PulseAudio or ALSA Linux system sound software. A recent PulseAudio 59 is the recommended configuration; see README-linux-voice.txt for more 60 information. 61 * Video/Graphics Card: 62 o nVidia GeForce 2, GeForce 4mx, or better (recommend one of the 63 following: 6700, 6800, 7600, 7800, 7900, 8400, 8500, 8600, 64 8800, Go 7400, Go 7600, Go 7800, Go 7900, +) 65 o OR ATI Radeon 8500, 9250, or better 66 (nVidia cards are recommended for the Linux client) 67 68 **NOTE**: Second Life absolutely requires you to have recent, correctly- 69 configured OpenGL 3D drivers for your hardware - the graphics drivers 70 that came with your operating system may not be good enough! See the 71 TROUBLESHOOTING section if you encounter problems starting Second Life. 72 73For a more comfortable experience, the RECOMMENDED hardware for the Second 74Life Linux client is very similar to that for Windows, as detailed at: 75<https://secondlife.com/corporate/sysreqs.php> 76 77 783. INSTALLING & RUNNING 79-=-=-=-=-=-=-=-=-=-=-=- 80 81The Second Life Linux client can entirely run from the directory you have 82unpacked it into - no installation step is required. If you wish to 83perform a separate installation step anyway, you may run './install.sh' 84 85Run ./secondlife from the installation directory to start Second Life. 86 87For in-world MOVIE and MUSIC PLAYBACK, you will need (32-bit) GStreamer 0.10 88installed on your system. This is optional - it is not required for general 89client functionality. If you have GStreamer 0.10 installed, the selection of 90in-world movies you can successfully play will depend on the GStreamer 91plugins you have; if you cannot play a certain in-world movie then you are 92probably missing the appropriate GStreamer plugin on your system - you may 93be able to install it (see TROUBLESHOOTING). 94 95User data is stored in the hidden directory ~/.secondlife by default; you may 96override this location with the SECONDLIFE_USER_DIR environment variable if 97you wish. 98 99 1004. KNOWN ISSUES 101-=-=-=-=-=-=-=- 102 103* No significant known issues at this time. 104 105 1065. TROUBLESHOOTING 107-=-=-=-=-=-=-=-=-= 108 109The client prints a lot of diagnostic information to the console it was 110run from. Most of this is also replicated in ~/.secondlife/logs/SecondLife.log 111- this is helpful to read when troubleshooting, especially 'WARNING' and 112'ERROR' lines. 113 114VOICE PROBLEMS? See the separate README-linux-voice.txt file for Voice 115 troubleshooting information. 116 117SPACENAVIGATOR OR JOYSTICK PROBLEMS? See the separate 118 README-linux-joystick.txt file for configuration information. 119 120PROBLEM 1:- Second Life fails to start up, with a warning on the console like: 121 'Error creating window.' or 122 'Unable to create window, be sure screen is set at 32-bit color' or 123 'SDL: Couldn't find matching GLX visual.' 124SOLUTION:- Usually this indicates that your graphics card does not meet 125 the minimum requirements, or that your system's OpenGL 3D graphics driver is 126 not updated and configured correctly. If you believe that your graphics 127 card DOES meet the minimum requirements then you likely need to install the 128 official so-called 'non-free' nVidia or ATI (fglrx) graphics drivers; we 129 suggest one of the following options: 130 * Consult your Linux distribution's documentation for installing these 131 official drivers. For example, Ubuntu provides documentation here: 132 <https://help.ubuntu.com/community/BinaryDriverHowto> 133 * If your distribution does not make it easy, then you can download the 134 required Linux drivers straight from your graphics card manufacturer: 135 - nVidia cards: <http://www.nvidia.com/object/unix.html> 136 - ATI cards: <http://ati.amd.com/support/driver.html> 137 138PROBLEM 2:- My whole system seems to hang when running Second Life. 139SOLUTION:- This is typically a hardware/driver issue. The first thing to 140 do is to check that you have the most recent official drivers for your 141 graphics card (see PROBLEM 1). 142SOLUTION:- Some residents with ATI cards have reported that running 143 'sudo aticonfig --locked-userpages=off' before running Second Life solves 144 their stability issues. 145SOLUTION:- As a last resort, you can disable most of Second Life's advanced 146 graphics features by editing the 'secondlife' script and removing the '#' 147 from the line which reads '#export LL_GL_NOEXT=x' 148 149PROBLEM 3:- After I minimize the Second Life window, it's just blank when 150 it comes back. 151SOLUTION:- Some Linux desktop 'Visual Effects' features are incompatible 152 with Second Life. One reported solution is to use your desktop 153 configuration program to disable such effects. For example, on Ubuntu 7.10, 154 use the desktop toolbar menu to select System -> Preferences -> Appearance, 155 then change 'Visual Effects' to 'None'. 156 157PROBLEM 4:- Music and sound effects are silent or very stuttery. 158SOLUTION:- The most common solution is to ensure that you have the 'esd' 159 program (part of the 'esound' package) installed and running before you 160 start Second Life. Users of Ubuntu (and some other) Linux systems can 161 simply run the following to install and configure 'esound': 162 sudo apt-get install esound 163 For others, simply running 'esd&' from a command-line should get it running. 164 165PROBLEM 5:- Using the 'Alt' key to control the camera doesn't work or just 166 moves the Second Life window. 167SOLUTION:- Some window managers eat the Alt key for their own purposes; you 168 can configure your window manager to use a different key instead (for 169 example, the 'Windows' key!) which will allow the Alt key to function 170 properly with mouse actions in Second Life and other applications. 171 172PROBLEM 6:- In-world movie, music, or Flash playback doesn't work for me. 173SOLUTION:- You need to have a working installation of GStreamer 0.10; this 174 is usually an optional package for most versions of Linux. If you have 175 installed GStreamer 0.10 and you can play some music/movies but not others 176 then you need to install a wider selection of GStreamer plugins, either 177 from your vendor (i.e. the 'Ugly' plugins) or an appropriate third party. 178 For Flash playback, you need to have Flash 10 installed for your normal 179 web browser (for example, Firefox). PulseAudio is required for Flash 180 volume control / muting to fully function inside Second Life. 181 182 1836. ADVANCED TROUBLESHOOTING 184-=-=-=-=-=-=-=-=-=-=-=-=-=- 185 186The 'secondlife' script which launches Second Life contains some 187configuration options for advanced troubleshooters. 188 189* AUDIO - Edit the 'secondlife' script and you will see these audio 190 options: LL_BAD_OPENAL_DRIVER, LL_BAD_FMOD_ESD, LL_BAD_FMOD_OSS, and 191 LL_BAD_FMOD_ALSA. Second Life tries to use OpenAL, ESD, OSS, then ALSA 192 audio drivers in this order; you may uncomment the corresponding LL_BAD_* 193 option to skip an audio driver which you believe may be causing you trouble. 194 195* OPENGL - For advanced troubleshooters, the LL_GL_BLACKLIST option lets 196 you disable specific GL extensions, each of which is represented by a 197 letter ("a"-"o"). If you can narrow down a stability problem on your system 198 to just one or two GL extensions then please post details of your hardware 199 (and drivers) to the Linux Client Testers forum (see link below) along 200 with the minimal LL_GL_BLACKLIST which solves your problems. This will help 201 us to improve stability for your hardware while minimally impacting 202 performance. 203 LL_GL_BASICEXT and LL_GL_NOEXT should be commented-out for this to be useful. 204 205 2067. OBTAINING AND WORKING WITH THE CLIENT SOURCE CODE 207-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 208 209We're pleased to have released the Second Life client's source code under 210an Open Source license compatible with the 'GPL'. To get involved with client 211development, please see: 212<http://wiki.secondlife.com/wiki/Open_Source_Portal> 213 214 2158. GETTING MORE HELP AND REPORTING PROBLEMS 216-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- 217 218For general help and support with Second Life: 219<http://secondlife.com/community/support.php> 220 221For problems and discussion concerning unofficial (not secondlife.com) 222releases, please contact your packager or the SLDev mailing list: 223<https://lists.secondlife.com/cgi-bin/mailman/listinfo/sldev> 224 225In-world help: Please use the 'Help' menu in the client for various 226non-Linux-specific Second Life help options. 227 228In-world discussion: There is a 'Linux Client Users' group 229inside Second Life which is free to join.
