Hi From the backtrace: > #7 0x0f6e1318 in __assert_fail () from /lib/tls/libc.so.6 > #8 0x0de59a18 in __glXPushArrayState () from /usr/lib/libGL.so.1 > #9 0x0de59a18 in __glXPushArrayState () from /usr/lib/libGL.so.1
and even clearer in the console log: > boson: indirect_vertex_array.c:1359: __indirect_glTexCoordPointer: Assertion > `a != ((void *)0)' failed. Your OpenGL driver is broken. Since you are using PowerPC/SPARC, I guess you use the DRI drivers? Well, "good" is not one of the adjectives I'd use to describe DRI drivers when it comes to 3D. Try to start boson using boson --indirect This should start boson without 3d accelleration and thus be very slow. However it should start then. If it works, it indeed is a driver bug. If it works with --indirect, you may want to try to edit ~/.kde/share/config/bosonrc and replace MeshRenderer=BoMeshRendererVertexArray by MeshRenderer=BoMeshRendererImmediate If you're lucky this might fix it for direct mode, too.
