Hi, Does anyone know how to restrict the available Visuals in X? I'm attaching a greyscale monitor, and want to exclude everything excet StaticGray. My xorg.conf file sets the default visual correctly; but xdpyinfo (and other applications) see lots of other visuals, attempt to use them, and make the screen unreadable.
This is the `screen' section from xorg.conf: Section "Screen" Identifier "GreyScale" Device "ATI Radeon X700 (RV410 PCIE):external" Monitor "GreyScale" DefaultDepth 8 SubSection "Display" Depth 8 Visual "StaticGray" EndSubsection EndSection But xdpyinfo gives: name of display: :0.0 version number: 11.0 vendor string: The X.Org Foundation vendor release number: 10400000 X.Org version: 1.4.0 maximum request size: 16777212 bytes motion buffer size: 256 bitmap unit, bit order, padding: 32, LSBFirst, 32 image byte order: LSBFirst number of supported pixmap formats: 7 supported pixmap formats: depth 1, bits_per_pixel 1, scanline_pad 32 depth 4, bits_per_pixel 8, scanline_pad 32 depth 8, bits_per_pixel 8, scanline_pad 32 depth 15, bits_per_pixel 16, scanline_pad 32 depth 16, bits_per_pixel 16, scanline_pad 32 depth 24, bits_per_pixel 32, scanline_pad 32 depth 32, bits_per_pixel 32, scanline_pad 32 keycode range: minimum 8, maximum 255 focus: window 0xa0000d, revert to Parent number of extensions: 33 BIG-REQUESTS Composite DAMAGE DEC-XTRAP DOUBLE-BUFFER DPMS Extended-Visual-Information GLX MIT-SCREEN-SAVER MIT-SHM MIT-SUNDRY-NONSTANDARD RANDR RECORD RENDER SECURITY SGI-GLX SHAPE SYNC TOG-CUP X-Resource XAccessControlExtension XC-APPGROUP XC-MISC XFIXES XFree86-Bigfont XFree86-DGA XFree86-Misc XFree86-VidModeExtension XINERAMA XInputExtension XKEYBOARD XTEST XVideo default screen number: 0 number of screens: 1 screen #0: dimensions: 1280x1024 pixels (325x260 millimeters) resolution: 100x100 dots per inch depths (7): 8, 1, 4, 15, 16, 24, 32 root window id: 0x56 depth of root window: 8 planes number of colormaps: minimum 1, maximum 1 default colormap: 0x20 default number of colormap cells: 256 preallocated pixels: black 0, white 255 options: backing-store NO, save-unders NO largest cursor: 64x64 current input event mask: 0x58007f KeyPressMask KeyReleaseMask ButtonPressMask ButtonReleaseMask EnterWindowMask LeaveWindowMask PointerMotionMask SubstructureNotifyMask SubstructureRedirectMask PropertyChangeMask number of visuals: 13 default visual id: 0x32 visual: visual id: 0x27 class: PseudoColor depth: 8 planes available colormap entries: 256 red, green, blue masks: 0x0, 0x0, 0x0 significant bits in color specification: 8 bits visual: visual id: 0x28 class: GrayScale depth: 8 planes available colormap entries: 256 red, green, blue masks: 0x0, 0x0, 0x0 significant bits in color specification: 8 bits visual: visual id: 0x29 class: StaticColor depth: 8 planes available colormap entries: 256 red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x2a class: TrueColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x2b class: TrueColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x2c class: TrueColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x2d class: TrueColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x2e class: DirectColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x2f class: DirectColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x30 class: DirectColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x31 class: DirectColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x32 class: StaticGray depth: 8 planes available colormap entries: 256 red, green, blue masks: 0x0, 0x0, 0x0 significant bits in color specification: 8 bits visual: visual id: 0x54 class: TrueColor depth: 32 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc AT gelato.unsw.edu.au http://www.ertos.nicta.com.au ERTOS within National ICT Australia -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
