Re: How to enable software rendering via X server
I set LIBGL_ALWAYS_SOFTWARE=1.But the output I got was the same: direct rendering: No OpenGL renderer string: Mesa DRI Intel(R) IGDNG_M GEM 20091221 2009Q4 Neeraj N.T drago01 wrote: On Mon, Feb 14, 2011 at 2:07 PM, Neeraj N T neera...@tataelxsi.co.in wrote: Hi All, By using the environment variable LIBGL_ALWAYS_INDIRECT=1 my glxinfo showed the following: direct rendering: No OpenGL renderer string: Mesa DRI Intel(R) IGDNG_M GEM 20091221 2009Q4 My research showed that the Xclient is actually using indirect rendering where as the Xserver is inturn using the DRI path. Instead of the above how can I get the below output, so that I can ensure graphics flow is using software rendering ? direct rendering: Yes OpenGL renderer string: Software Rasterizer You'd have to set LIBGL_ALWAYS_SOFTWARE=1 ... indirect rendering does NOT mean software rendering. ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
How to build a Xserver module with the tar ball source code xorg-server-1.9.3
Hi Dear XORG, I've download the tar ball xorg-server-1.9.3 source code from the www.x.org, but I can't find the build detail step base on the source code, would you pls tell me how to build the source code to generate a Xserver module or the online link to do that?

[drm:r600_ring_test] *ERROR* radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD)
Hi all. I've somehow broken 3D accel on my system. I'm not quite sure if it was me, my distro, if there is a regression, or if my hardware has issues. I did a fairly major system update ( Sabayon ) ... and rebuilt manually: 2.6.37 kernel with modesetting mesa from git libdrm from git latest radeon firmware Now I'm getting: [ 44.612719] [drm:r600_ring_test] *ERROR* radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD) [ 44.612724] radeon :01:05.0: disabling GPU acceleration ... and obviously 3D accel is no longer working. I've also tried with a 2.6.36 kernel with modesetting, which was working previously ... it gives the same error now. Any ideas? Thanks for any help :) Dan ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com

I don't think you can easily control which dri driver the server opens, but I might be wrong. So, if you have LIBGL_ALWAYS_SOFTWARE set and LIBGL_ALWAYS_INDIRECT unset, then you should get direct rendering with the swrast. To review, LIBGL_ALWAYS_INDIRECT: use the X server's GLX context. This used to mean you'd also get software rendering, but with AIGLX you'll probably get the hardware DRI driver. LIBGL_ALWAYS_SOFTWARE: tell libGL to use the software renderer. This only works with direct rendering because otherwise you're getting the DRI driver that the X server opened, and it's not controlled by this variable. -- Dan ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
Re: How to enable software rendering via X server
I unset LIBGL_ALWAYS_INDIRECT and set only LIBGL_ALWAYS_SOFTWARE but the output was still the same.
