SDL: Couldn't find matching GLX visual

hi, i'm trying to run Second Life here

my DefaultDepth is 24, but it is still asking for 32-bit color
and i got this another error, "SDL: Couldn't find matching GLX visual"

here is the log

You need accelerated (proprietary) nvidia/ati drivers installed.

i'm using an Intel VGA, it has opengl, i can run glxgears without problems
i only can run Second Life with nvidia or ATI?

paulo@foo:~$ lspci |grep VGA
0000:00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)

i'm using the i810 driver

It may work. Make sure you have glx/dri activated:

output from glxinfo | grep direct

also output from glxgears would help.

yes, it is
i'm getting some weird warning messages, but glxgears works without problems, Scorched 3D, etc.

i think this could be a Second Life problem
http://www.penguin-soft.com/penguin/man/3/SDL_GL_SetAttribute.html

here i found some pieces of code, about using GL attributes
as it seems, Second Life tries to start with 800x600x24, doesn't?

i've configured my xorg to run with 24bpp, but isn't working
maybe trying with 800x600x16, just doing some checks during the start

if ( (screen=SDL_SetVideoMode( 800, 600, 24, SDL_OPENGL )) == NULL ) {
fprintf(stderr, "Couldn't set GL mode: %s, trying with 16bpp", SDL_GetError());
} elseif( (screen=SDL_SetVideoMode( 800, 600, 16, SDL_OPENGL )) == NULL ) {
fprintf(stderr, "Couldn't set GL mode: %s, exiting", SDL_GetError());
}

other solution, maybe an better one:
screen = SDL_SetVideoMode(800,600,0,SDL_OPENGL) (which will inherit whatever bit depth the X server's running at.)
from: http://www.libsdl.org/pipermail/sdl/2003-May/054501.html

ps: i didn't tested this code, it's just an idea

Please post the full output of glxinfo. I suspect that the card may not support 24-bit depth-buffer and 8-bit destination alpha, which are currently required. We'll see...

i was looking into scorched3d source, witch runs without problems here:

// Try to create suface
surface = SDL_SetVideoMode( width, height, bpp, flags);

// If this fails
// Hack, to check if 16bit depth will work instead if 24 bits specified
if (!surface &&
depthBufferBits == 24)
{
SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 16);
surface = SDL_SetVideoMode( width, height, bpp, flags);
}

from: http://www.google.com/codesearch?q=+package:scorched3d+SDL_SetVideoMode+show:VuaQZUfyPoI:U_PRcd4-4Ng:sm-0hGs0FyQ&sa=N&cd=3&ct=rc&cs_p=http://ftp.sh.cvut.cz/MIRRORS/rock/ROCK-2.1/S/Scorched3D-39.1-src.tar.bz2&cs_f=scorched/src/common/Display.cpp#a0

i think libgl could have a support bug to my VGA, i bought my computer a few weeks ago, i don't think that new VGA models cannot support 24bpp

Hi again Paulo!
This driver/card combination does not appear to support Destination Alpha, so is not usable in Second Life at this time. A future release may relax this restriction a little (but some things will not work correctly for you, such as clothing adjustment).

i don't know much about graphics programming, opengl, etc
but i hope my suggestions may be helpful in some way, displaying warning messages instead of just exiting could fix problems like this (libgl issues)

i'm upgrading now to Edgy beta release of ubuntu, witch comes with xorg 7.1, i'll try to run second life again, and post my feedback here

To answer an earlier question directly, yes, you need an NVidia or ATI card to run Second Life. Intel's accellerated graphics do not have the right features that SL requires.

I seem to have the same problem with my graphic card which is a:
S3 Inc. VT8375 [ProSavage8 KM266/KL266]
, on a packard bell easynote e1245.
This is really too bad !!!

I bought an ATI Radeon 9600 and upgraded my OS (to Mepis 6.0) just to use the SL Linux client, but I'm getting the same error - SDL: Couldn't find matching GLX visual - although all my other 3D programs seem to work. Don't know if i'm using ATI propretary drivers or not, but i assume I am, how could I tell? And if that's not the problem, where do I start?

Ugh. I know about the S3's and Savages. There is no binary driver OpenGL support, so you're using whatever openGL drivers X11 has. Plus, Via bought S3, so you're out of luck on support. If you were thinking about upgrading to a new laptop, now is the time.

I doubt you are. Open up a terminal window or shell, and type 'less /etc/X11/xorg.conf'. This will get you the Xorg configuration file for the graphics display. Page down (pagedown key works) until you see a Driver line inside a graphics card section. It's not exactly cryptic, so you will have some clues and can say "Keyboard? Mouse? Nah.... Monitor? More more... card! Wait a minute, this is using the radeon driver and not the binary fglrx driver..."

yes, you're right, so how do I install and then use the driver?

or possibly

Should help...

i've updated my ubuntu system from dapper to edgy. now second life works fine with my Intel VGA

thanks ppl =)
