On my Thinkpad T42 with a Radeon "R300 (RV350 4E50)", pymol-1.5.0.1 segfaults when I run the Representations Demo: Detected OpenGL version prior to 2.0. Shaders and volumes unavailable. OpenGL graphics engine: GL_VENDOR: DRI R300 Project GL_RENDERER: Mesa DRI R300 (RV350 4E50) 20090101 x86/MMX/SSE2 TCL DRI2 GL_VERSION: 1.5 Mesa 7.7.1 Segmentation fault On my Tinkpad T400 with "Mobile Intel GM45 Express", I see only lines, mesh and dots in the Representations Demo, and a couple of "unsupported IR in fragement shader 13" messages: Detected OpenGL version 2.0 or greater. Shaders available. Detected GLSL version 1.20. OpenGL graphics engine: GL_VENDOR: Tungsten Graphics, Inc GL_RENDERER: Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20091221 2009Q4 GL_VERSION: 2.1 Mesa 7.7.1 Detected 2 CPU cores. Enabled multithreaded rendering. unsupported IR in fragment shader 13 unsupported IR in fragment shader 13 unsupported IR in fragment shader 13 unsupported IR in fragment shader 13 unsupported IR in fragment shader 13 unsupported IR in fragment shader 13 unsupported IR in fragment shader 13 This is both on Debian stable. So I have held off uploading pymol-1.5 to unstable for now and just put it into experimental.
