<div dir="ltr">Hello lists members, I'm having problems on using compiz and kwin with desktop effects (from kde4). Compiz can't find the GLX_EXT_texture_from_pixmap extension so it workaround to use indirect rendenring: [braulio@myhost ~]$ fusion-icon * Detected Session: kde * Searching for installed applications... * Intel detected, exporting: INTEL_BATCH=1 * No GLX_EXT_texture_from_pixmap with direct rendering context ... present with indirect rendering, exporting: LIBGL_ALWAYS_INDIRECT=1 * Using the GTK Interface * Starting Compiz ... executing: compiz --replace --sm-disable --ignore-desktop-hints ccp --indirect-rendering With this, the performance is of course a bit slower. With kwin is much worser, as it returns: kwin: X Error (error: GLXUnsupportedPrivateRequest[GLX+8], request: X_GLXVendorPrivateWithReply[GLX+17], resource: 0x1000a) kwin: X Error (error: GLXUnsupportedPrivateRequest[GLX+8], request: X_GLXVendorPrivateWithReply[GLX+17], resource: 0x1000a) kwin: X Error (error: GLXUnsupportedPrivateRequest[GLX+8], request: X_GLXVendorPrivateWithReply[GLX+17], resource: 0x1000a) kwin: X Error (error: GLXUnsupportedPrivateRequest[GLX+8], request: X_GLXVendorPrivateWithReply[GLX+17], resource: 0x1000a) kwin: X Error (error: GLXUnsupportedPrivateRequest[GLX+8], request: X_GLXVendorPrivateWithReply[GLX+17], resource: 0x1000a) kwin: X Error (error: GLXUnsupportedPrivateRequest[GLX+8], request: X_GLXVendorPrivateWithReply[GLX+17], resource: 0x1000a) and isn't smart enough to work with indirect rendering, so I can't use it with the composite extension. The strange thing is that running glxinfo I can see the GLX_EXT_texture_from_pixmap extension: [braulio@myhost ~]$ glxinfo name of display: :0.0 display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.2 server glx extensions: GLX_ARB_multisample, GLX_EXT_import_context, GLX_EXT_texture_from_pixmap, GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_MESA_copy_sub_buffer, GLX_OML_swap_method, GLX_SGI_make_current_read, GLX_SGI_swap_control, GLX_SGIS_multisample, GLX_SGIX_fbconfig, GLX_SGIX_visual_select_group client glx vendor string: SGI client glx version string: 1.4 client glx extensions: GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_EXT_import_context, GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_MESA_allocate_memory, GLX_MESA_copy_sub_buffer, GLX_MESA_swap_control, GLX_MESA_swap_frame_usage, GLX_OML_swap_method, GLX_OML_sync_control, GLX_SGI_make_current_read, GLX_SGI_swap_control, GLX_SGI_video_sync, GLX_SGIS_multisample, GLX_SGIX_fbconfig, GLX_SGIX_pbuffer, GLX_SGIX_visual_select_group, GLX_EXT_texture_from_pixmap GLX version: 1.2 GLX extensions: GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_EXT_import_context, GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_MESA_copy_sub_buffer, GLX_MESA_swap_control, GLX_MESA_swap_frame_usage, GLX_OML_swap_method, GLX_SGI_make_current_read, GLX_SGI_swap_control, GLX_SGI_video_sync, GLX_SGIS_multisample, GLX_SGIX_fbconfig, GLX_SGIX_visual_select_group OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) 965GM 4.1.3002 OpenGL version string: 1.4 Mesa 7.0.3 OpenGL extensions: GL_ARB_depth_texture, GL_ARB_fragment_program, GL_ARB_imaging, GL_ARB_multisample, GL_ARB_multitexture, GL_ARB_point_parameters, GL_ARB_shadow, GL_ARB_texture_border_clamp, GL_ARB_texture_compression, GL_ARB_texture_cube_map, GL_ARB_texture_env_add, GL_ARB_texture_env_combine, GL_ARB_texture_env_crossbar, GL_ARB_texture_env_dot3, GL_ARB_texture_mirrored_repeat, GL_ARB_texture_non_power_of_two, GL_ARB_texture_rectangle, GL_ARB_transpose_matrix, GL_ARB_vertex_buffer_object, GL_ARB_vertex_program, GL_ARB_window_pos, GL_EXT_abgr, GL_EXT_bgra, GL_EXT_blend_color, GL_EXT_blend_equation_separate, GL_EXT_blend_func_separate, GL_EXT_blend_logic_op, GL_EXT_blend_minmax, GL_EXT_blend_subtract, GL_EXT_clip_volume_hint, GL_EXT_cull_vertex, GL_EXT_compiled_vertex_array, GL_EXT_convolution, GL_EXT_copy_texture, GL_EXT_draw_range_elements, GL_EXT_fog_coord, GL_EXT_histogram, GL_EXT_multi_draw_arrays, GL_EXT_packed_pixels, GL_EXT_point_parameters, GL_EXT_polygon_offset, GL_EXT_rescale_normal, GL_EXT_secondary_color, GL_EXT_separate_specular_color, GL_EXT_shadow_funcs, GL_EXT_stencil_wrap, GL_EXT_subtexture, GL_EXT_texture, GL_EXT_texture3D, GL_EXT_texture_edge_clamp, GL_EXT_texture_env_add, GL_EXT_texture_env_combine, GL_EXT_texture_env_dot3, GL_EXT_texture_filter_anisotropic, GL_EXT_texture_lod_bias, GL_EXT_texture_object, GL_EXT_texture_rectangle, GL_EXT_vertex_array, GL_3DFX_texture_compression_FXT1, GL_APPLE_client_storage, GL_APPLE_packed_pixels, GL_ATI_blend_equation_separate, GL_IBM_rasterpos_clip, GL_IBM_texture_mirrored_repeat, GL_INGR_blend_func_separate, GL_MESA_pack_invert, GL_MESA_ycbcr_texture, GL_MESA_window_pos, GL_NV_blend_square, GL_NV_light_max_exponent, GL_NV_texture_rectangle, GL_NV_texgen_reflection, GL_OES_read_format, GL_SGI_color_matrix, GL_SGI_color_table, GL_SGIS_generate_mipmap, GL_SGIS_texture_border_clamp, GL_SGIS_texture_edge_clamp, GL_SGIS_texture_lod, GL_SGIX_depth_texture, GL_SUN_multi_draw_arrays visual x bf lv rg d st colorbuffer ax dp st accumbuffer ms cav id dep cl sp sz l ci b ro r g b a bf th cl r g b a ns b eat ---------------------------------------------------------------------- 0x23 24 tc 0 32 0 r y . 8 8 8 8 0 0 0 0 0 0 0 0 0 None 0x24 24 tc 0 32 0 r . . 8 8 8 8 0 0 0 0 0 0 0 0 0 None 0x25 24 tc 0 32 0 r y . 8 8 8 8 0 24 8 0 0 0 0 0 0 None 0x26 24 tc 0 32 0 r . . 8 8 8 8 0 24 8 0 0 0 0 0 0 None 0x27 24 tc 0 32 0 r y . 8 8 8 8 0 0 0 16 16 16 16 0 0 Slow 0x28 24 tc 0 32 0 r . . 8 8 8 8 0 0 0 16 16 16 16 0 0 Slow 0x29 24 tc 0 32 0 r y . 8 8 8 8 0 24 8 16 16 16 16 0 0 Slow 0x2a 24 tc 0 32 0 r . . 8 8 8 8 0 24 8 16 16 16 16 0 0 Slow 0x2b 24 dc 0 32 0 r y . 8 8 8 8 0 0 0 0 0 0 0 0 0 None 0x2c 24 dc 0 32 0 r . . 8 8 8 8 0 0 0 0 0 0 0 0 0 None 0x2d 24 dc 0 32 0 r y . 8 8 8 8 0 24 8 0 0 0 0 0 0 None 0x2e 24 dc 0 32 0 r . . 8 8 8 8 0 24 8 0 0 0 0 0 0 None 0x2f 24 dc 0 32 0 r y . 8 8 8 8 0 0 0 16 16 16 16 0 0 Slow 0x30 24 dc 0 32 0 r . . 8 8 8 8 0 0 0 16 16 16 16 0 0 Slow 0x31 24 dc 0 32 0 r y . 8 8 8 8 0 24 8 16 16 16 16 0 0 Slow 0x32 24 dc 0 32 0 r . . 8 8 8 8 0 24 8 16 16 16 16 0 0 Slow 0x67 32 tc 0 32 0 r . . 8 8 8 8 0 0 0 0 0 0 0 0 0 Ncon That leads me to thing about to options: I have an installation problem or the driver doesn't support this extension togheter with direct rendering.
