You can skip the above lines if you just change the monitor identifiers to match your output names. Also, I'm not sure that having relative locations for every monitor will work correctly. For the farthest left one, leave out the orientation. > EndSection Try something like this: Section "Device" Identifier "ati-5450" EndSection Section "Monitor" Identifier "DVI-0" EndSection Section "Monitor" Identifier "DisplayPort-0" Option "RightOf" "DVI-0" EndSection Section "Monitor" Identifier "VGA-0" Option "RightOf" "DisplayPort-0" EndSection > > Section "Monitor" > Identifier "left" > EndSection > > Section "Monitor" > Identifier "middle" > Option "RightOf" "left" > EndSection > > Section "Monitor" > Identifier "right" > Option "RightOf" "middle" > EndSection > > and here is the output of xrandr: > $ xrandr > Screen 0: minimum 320 x 200, current 5440 x 1200, maximum 8192 x 8192 > DisplayPort-0 connected 1920x1200+1920+0 (normal left inverted right x axis > y axis) 518mm x 324mm > 1920x1200 60.0*+ > 1920x1080 60.0 1600x1200 60.0 1680x1050 60.0 > 1280x1024 60.0 1280x960 60.0 1024x768 60.0 > 800x600 60.3 640x480 60.0 720x400 70.1 DVI-0 > connected 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x > 324mm > 1920x1200 60.0*+ > 1920x1080 50.0 60.0 1600x1200 60.0 1680x1050 > 59.9 1280x1024 60.0 1440x900 59.9 1280x960 60.0 > 1280x800 59.9 1280x720 50.0 60.0 1024x768 60.0 > 800x600 60.3 56.2 720x576 50.0 720x480 59.9 > 640x480 60.0 VGA-0 connected 1600x1200+3840+0 (normal left inverted > right x axis y axis) 408mm x 306mm > 1600x1200 60.0*+ > 1280x1024 75.0 60.0 1280x960 60.0 1152x864 > 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 > 800x600 72.2 75.0 60.3 56.2 640x480 72.8 > 75.0 66.7 60.0 720x400 70.1 > Any suggestions on how to make a working xorg.conf? > > Fedora 18 x86_64: > xorg-x11-server-Xorg-1.13.3-3.fc18.x86_64 > xorg-x11-drv-ati-7.0.0-0.9.20121015gitbd9e2c064.fc18.x86_64 > $ xrandr --version > xrandr program version 1.4.0 > Server reports RandR version 1.4 > -- > Nick Urbanik http://nicku.org ni...@nicku.org > GPG: 7FFA CDC7 5A77 0558 DC7A 790A 16DF EC5B BB9D 2C24 ID: BB9D2C24 > _______________________________________________ > xorg@lists.x.org: X.Org support > Archives: http://lists.freedesktop.org/archives/xorg > Info: http://lists.x.org/mailman/listinfo/xorg > Your subscription address: alexdeuc...@gmail.com _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
