Thanks, I might try the official drivers, but not only is my card a 7500, it's a Mobility card, which ATI says it absolutely does not support (they say drivers are the laptop manufacturer's responsibility).
Are there any plans for partial support for older GLX versions? In my experience it seems that most people use the dri.sf.net drivers, but I might be wrong.
Thanks, -Keith

Hi Keith,
It sounds like your DRI drivers are fairly up-to-date, but I believe that all DRI-based drivers only support GLX 1.2. And as you mention, the OGL-based Java 2D pipeline requires GLX 1.3 (for using pbuffers, locating appropriate visuals, etc).
ATI, Nvidia, and Sun (and possibly others) ship OpenGL drivers with GLX 1.3 or higher. The DRI project is the notable exception here. Normally, I would suggest that you install the Linux drivers from ATI's website, but I believe their accelerated drivers are for the Radeon 8500 and above only (and probably wouldn't work for your Radeon 7500 based board).
I've heard talk of DRI supporting GLX 1.3 features (i.e. pbuffers), but apparently that work has stalled. Until that support is available, I'm afraid you're out of luck.
In fact, I just googled for more information, and came across this recent post on the dri-devel list: http://www.mail-archive.com/[EMAIL PROTECTED]/msg15273.html
It sounds like the community is interested in GLX 1.3 support from DRI, but it seems that there are no DRI developers currently addressing this feature (a familiar scenario is the wonderful world of open source software).
Thanks, Chris

The JDK1.5 beta release notes say that you need GLX version 1.3 or higher to use the new OpenGL pipeline. I think I have the latest OpenGL/DRI/DRM/AGP drivers, but my "glxinfo" command shows that my client and server GLX are only at version 1.2.
(Other 3D OpenGL applications work fine and run fast, but I can't run Java 1.5 beta with the OpenGL pipeline - the "using OpenGL pipeline" message does not appear.)
My system log says "[drm] Initialized radeon 1.10.0 20020828 on minor 0: ATI Radeon LW Mobility 7500 M7"
glxinfo says: server glx vendor string: SGI server glx version string: 1.2 server glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context client glx vendor string: SGI client glx version string: 1.2 client glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
Also, as the release notes say is required, I do have GL_ARB_imaging enabled, and I have up to date OpenGL driver: OpenGL vendor string: Tungsten Graphics, Inc. OpenGL renderer string: Mesa DRI Radeon 20020611 AGP 1x x86/MMX/SSE TCL OpenGL version string: 1.2 Mesa 4.0.4
My question is, how can I find the latest drivers? I think I'm using the latest drivers. Another question is, why do other applications run fine, but Java requires a newer version?
Thanks, -Keith
