Not sure I'm on the right list(s) -- if not, a suggestion for another one would be welcome. I normally don't run 3D apps and haven't set the X.org "AGPSize" option which (I believe) means or meant it uses a default 8MB. Today I was playing around a bit with 3D and saw rather long delays upon starting and exiting X depending on the size set. X is "X.org X Server 1.4.2", kernel is 2.6.26. Hardware is an AGP Matrox Millenium G550 32MB (X driver "mga", kernel CONFIG_DRM_MGA) and the AGP GART is AMD 751, CONFIG_AGP_AMD. CPU is a Duron 1300. During testing, the AGP aperture was set to 256M in the BIOS, normally it's 64M. AGP mode is 2x (Option "AGPMode" "2"). Without an AGPSize option or with Option "AGPSize "8", the delay between my monitor switching to graphics mode and my desktop appearing is about 2 seconds: No/8 : 2 seconds 16 : 3 seconds 32 : 4 seconds 64 : 6 seconds 128 : 12 seconds Similar (somewhat shorter, but related in the same way) delays are present upon exiting X again as well, from the point where my monitor switches to text mode to me getting back a prompt. I have played around with 3D before and am sure that back then the 64M setting did not produce any delays over not having the option set. That 6 seconds now is rather long, and especially the one while exiting X feels odd. Are these delays expected? And/or not a DRM/AGP but X issue? Mesa seems to be 7.0.2 if it matters: # glxinfo | head -29 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_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_EXT_texture_from_pixmap, GLX_OML_swap_method, GLX_SGI_make_current_read, GLX_SGIS_multisample, GLX_SGIX_hyperpipe, GLX_SGIX_swap_barrier, GLX_SGIX_fbconfig, GLX_MESA_copy_sub_buffer 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_swap_control, GLX_MESA_swap_frame_usage, GLX_OML_swap_method, GLX_SGI_make_current_read, GLX_SGI_video_sync, GLX_SGIS_multisample, GLX_SGIX_fbconfig OpenGL vendor string: VA Linux Systems Inc.
