Hello, I have bought a mini-VGA to VGA adapter for my iBook G3 800 MHz 12 inch. When I use the adapter to connect an external VGA display to my iBook G3: - in Mac OS X, everything is fine, I can see my desktop both on the iBook LCD display and on the external VGA display - in Debian GNU/Linux, I can see my desktop on the iBook LCD display, but I see nothing but a grey screen on the external VGA display Here is my /etc/X11/xorg.conf: (I have already modified it in order to support an external VGA display) 1 # /etc/X11/xorg.conf (xorg X Window System server configuration file) 2 # 3 # Dernière modification: Pierre Bauduin, le 1er juin 2007 à 20h50 4 # 5 # This file was generated by dexconf, the Debian X Configuration tool, using 6 # values from the debconf database. 7 # 8 # Edit this file with caution, and see the /etc/X11/xorg.conf manual page. 9 # (Type "man /etc/X11/xorg.conf" at the shell prompt.) 10 # 11 # This file is automatically updated on xserver-xorg package upgrades *only* 12 # if it has not been modified since the last upgrade of the xserver-xorg 13 # package. 14 # 15 # If you have edited this file but would like it to be automatically updated 16 # again, run the following command: 17 # sudo dpkg-reconfigure -phigh xserver-xorg 18 Section "Files" 19 FontPath "/usr/share/fonts/X11/misc" 20 FontPath "/usr/X11R6/lib/X11/fonts/misc" 21 FontPath "/usr/share/fonts/X11/cyrillic" 22 FontPath "/usr/X11R6/lib/X11/fonts/cyrillic" 23 FontPath "/usr/share/fonts/X11/100dpi/:unscaled" 24 FontPath "/usr/X11R6/lib/X11/fonts/100dpi/:unscaled" 25 FontPath "/usr/share/fonts/X11/75dpi/:unscaled" 26 FontPath "/usr/X11R6/lib/X11/fonts/75dpi/:unscaled" 27 FontPath "/usr/share/fonts/X11/Type1" 28 FontPath "/usr/X11R6/lib/X11/fonts/Type1" 29 FontPath "/usr/share/fonts/X11/100dpi" 30 FontPath "/usr/X11R6/lib/X11/fonts/100dpi" 31 FontPath "/usr/share/fonts/X11/75dpi" 32 FontPath "/usr/X11R6/lib/X11/fonts/75dpi" 33 # path to defoma fonts 34 FontPath "/var/lib/defoma/x- ttcidfont-conf.d/dirs/TrueType" 35 EndSection 36 Section "Module" 37 Load "i2c" 38 Load "bitmap" 39 Load "ddc" 40 Load "dri" 41 Load "extmod" 42 Load "freetype" 43 Load "glx" 44 Load "int10" 45 Load "vbe" 46 EndSection 47 Section "InputDevice" 48 Identifier "Generic Keyboard" 49 Driver "kbd" 50 Option "CoreKeyboard" 51 Option "XkbRules" "xorg" 52 # Pierre Bauduin le 12 mai 2007 53 # D'après le hack 4 de "Debian à 200%" page 15 ISBN 2841773671 54 #Option "XkbModel" "pc104" 55 Option "XkbModel" "macintosh" 56 #Option "XkbLayout" "us" 57 #Option "XkbLayout" "be" 58 Option "XkbLayout" "fr" 59 EndSection 60 Section "InputDevice" 61 Identifier "Configured Mouse" 62 Driver "mouse" 63 Option "CorePointer" 64 Option "Device" "/dev/input/mice" 65 Option "Protocol" "ImPS/2" 66 Option "Emulate3Buttons" "true" 67 EndSection 68 Section "InputDevice" 69 Identifier "Synaptics Touchpad" 70 Driver "synaptics" 71 Option "SendCoreEvents" "true" 72 Option "Device" "/dev/psaux" 73 Option "Protocol" "auto-dev" 74 Option "HorizScrollDelta" "0" 75 EndSection 76 Section "Device" 77 Identifier "ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]" 78 Driver "ati" 79 BusID "PCI:0:16:0" 80 Option "UseFBDev" "true" 81 # Ajout Pierre Bauduin le 1er juin 2007 82 Option "MonitorLayout" "LVDS,VGA" 83 Option "CRT2HSync" "30 -
