I am trying to get transparency and drop shadows to work on my FC4 box and am having some difficulty. I set this up on my laptop with FC4 running under VMWare and it works like a charm. However, the same process does not seem to work when booted directly to Linux. I am running a current Nvidia card with dual head support. The TwinView setup is working perfectly. The device section of my xorg.conf looks like: Section "Device" Identifier "Videocard0" VendorName "nVidia Corporation" Driver "nvidia" BusID "PCI:01:00:0" Screen 0 Option "SecondMonitorHorizSync" "31.0 - 80.0" Option "SecondMonitorVertRefresh" "56.0 - 75.0" Option "MetaModes" "1280x1024,1280x1024; 1024X768,1024X768; 800x600,800x600" Option "TwinView" Option "TwinViewOrientation" "RightOf" EndSection Module section: Section "Module" Load "dbe" Load "extmod" Load "fbdevhw" Load "glx" Load "record" Load "freetype" Load "type1" EndSection Screen Section: Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" "1024x768" "800x600" "640x400" EndSubSection EndSection When I try to add the Extensions section: Section "Extensions" Option "Composite" "true" EndSection vim highlights the "EndSection" line as if it is an error. And, sure enough, when I try to restart X with the new section, it refuses to start. Has anybody gotten this to work on their machine? Is this a no-can-do with dual head? Is there something that I am missing? Any assistance would be appreciated.
