xrandr reports "VGA-0 disconnected", but it certainly is connected, and both Ubuntu and XP can find it OK on the same hardware. I suspect a very recent ATI driver update has made this worse: xrandr used to find the screen, though it was blank. I could make it mirror the laptop display by saying "xrandr --output LVDS --mode 800x600" followed by "xrandr --output LVDS --mode 1024x768" But now nothing seems to work... Laptop attached to docking station, and through that to an external display. Booting F8, external display behaves normally at first, but when graphical stuff starts, it goes blank and stays blank. Laptop display continues to work normally. I'm only trying to display the same desktop simultaneously on both displays. No split desktops or double desktops, or anything fancy. It all worked properly with FC5, and subsequent upgrades to FC6 and then F7. Problem appeared only on upgrade to F8. All F8 updates applied. Everything still works normally if I boot Windows XP instead of F8. Config is: Compaq Evo N1020v laptop with Radeon IGP 340M graphics. External display is just an old Gateway EV500 15" CRT. Both displays are 1024*768. /etc/X11/xorg.conf reads: Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "gb" EndSection Section "Monitor" Identifier "Monitor0" ModelName "LCD Panel 1024x768" HorizSync 31.5 - 37.9 VertRefresh 50.0 - 70.0 EndSection Section "Device" Identifier "Videocard0" Driver "radeon" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection SubSection "Display" Viewport 0 0 Depth 16 Modes "800x600" EndSubSection EndSection If anyone can see what's wrong here, I'll be very grateful!
