1. INTRODUCTION
-=-=-=-=-=-=-=-
Hi! This is a BETA release of the Second Life client for Linux.
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' for accessing Second Life.
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.
You will have either obtained this client from secondlife.com (the official
site) or from a third-party packager; if you encounter any problems then
we recommend trying the latest official builds from secondlife.com which are
updated often.
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: 512MB (recommended: 768MB or more)
* 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**: Second Life 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 Second Life.
For a more comfortable experience, the RECOMMENDED hardware for the Second
Life Linux client is very similar to that for Windows, as detailed at:
<https://secondlife.com/corporate/sysreqs.php>
3. INSTALLING & RUNNING
-=-=-=-=-=-=-=-=-=-=-=-
The Second Life 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 ./secondlife from the installation directory to start Second Life.
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 ~/.secondlife by default; you may
override this location with the SECONDLIFE_USER_DIR 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 ~/.secondlife/logs/SecondLife.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:- Second Life 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:
<https://help.ubuntu.com/community/BinaryDriverHowto>
* If your distribution does not make it easy, then you can download the
required Linux drivers straight from your graphics card manufacturer:
- nVidia cards: <http://www.nvidia.com/object/unix.html>
- ATI cards: <http://ati.amd.com/support/driver.html>
PROBLEM 2:- My whole system seems to hang when running Second Life.
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 Second Life solves
their stability issues.
SOLUTION:- As a last resort, you can disable most of Second Life's advanced
graphics features by editing the 'secondlife' script and removing the '#'
from the line which reads '#export LL_GL_NOEXT=x'
PROBLEM 3:- After I minimize the Second Life window, it's just blank when
it comes back.
SOLUTION:- Some Linux desktop 'Visual Effects' features are incompatible
with Second Life. 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 Second Life. 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 Second Life 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 Second Life 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 Second Life.
6. ADVANCED TROUBLESHOOTING
-=-=-=-=-=-=-=-=-=-=-=-=-=-
The 'secondlife' script which launches Second Life 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_FMOD_ESD, LL_BAD_FMOD_OSS, and
LL_BAD_FMOD_ALSA. Second Life tries to use OpenAL, ESD, OSS, then 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 the Second Life client's source code under
an Open Source license compatible with the 'GPL'. To get involved with client
development, please see:
