I have IBM Thinkpad R52 and with external monitor connected on boot I have grub only on external LCD. But during the boot internal LCD on laptop also goes on and when I'm presented GDM to login to my Fedora Core 6 I have picture on both monitors. I tied your tips and pressing FN-F7 twice so that I get grub only on laptop and then again only on external LCD and then closing the lid (I have wireless USB keyboard)... but that still didn't work! I have this xorg.conf file: # cat /etc/X11/xorg.conf # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Synaptics" "CorePointer" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "hr" EndSection Section "InputDevice" Identifier "Synaptics" Driver "synaptics" Option "Device" "/dev/input/mice" Option "Protocol" "auto-dev" Option "Emulate3Buttons" "yes" EndSection Section "Monitor" ### Comment all HorizSync and VertSync values to use DDC: Identifier "Monitor0" ModelName "LCD Panel 1280x1024" ### Comment all HorizSync and VertSync values to use DDC: HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 Option "dpms" EndSection Section "Device" Identifier "Videocard0" Driver "intel" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1024x768" "800x600" "640x480" # Modes "1280x800" "1152x864" "1152x768" "1024x768" "800x600" Option "ModeValidation" "NoMaxPClkCheck" EndSubSection and If I enable "1280x800" mode I get desktop of 1280x800 but I get resolution of 1024x768 and I can pan around the bigger desktop... really not what I had in mind :) Do you please have any others ideas?
