[Linux] 945GM + ATI 9250 PCI card = upto 4 displays

這兩天又有客戶想要我們Linux support, what a free rider!
言歸正傳, 今次的主題是945GM(CRT, LVDS) + AIT 9250 PCI(CRT, DVI), 在xorg 下要輸出Quad Displays (謎之音, 為何不用4, 要用quad!? 客倌不覺得這樣比較炫嗎?)

首先, 要先檢查是不是所有的vga 都有認到, 抄傢伙 "lspci"

frodo@frodo-desktop:~$ lspci

報告, 在"00:02.0" "01:06.0" 發現有不明vga 出没, 所以就順手記下這些位置.

正式動工了! 拿xorg.conf 來開刀吧!
首先是945GM 部分:

Section "Device"
        Identifier      "945GM"
        Driver          "i810"
        BusID           "PCI:0:2:0"
        Option "MonitorLayout" "CRT,LFP" 
        Screen          0
EndSection

Section "Device"
        Identifier      "945GM-1"
        Driver          "i810"
        BusID           "PCI:0:2:0"
        Screen          1
EndSection

再來處理ATI:

Section "Device"
        Identifier      "ati"
        Driver          "radeon"
        BusID           "PCI:1:6:0"
        Option          "CRT,TMDS"
        Screen          2
EndSection

Section "Device"
        Identifier      "ati-1"
        Driver          "radeon"
        BusID           "PCI:1:6:0"
        Option          "CRT,TMDS"
        Screen          3
EndSection

設定Monitor type

Section "Monitor"
        Identifier      "Acer AL1711"
        Option          "DPMS"
EndSection

Section "Monitor"
        Identifier      "Acer AL1711-1"
        Option          "DPMS"
EndSection
Section "Monitor"
        Identifier      "Acer AL1711-2"
        Option          "DPMS"
EndSection

Section "Monitor"
        Identifier      "Acer AL1711-3"
        Option          "DPMS"
EndSection

設定Screen,

Section "Screen"
        Identifier      "Screen0"
        Device          "945GM"
        Monitor         "Acer AL1711"
        DefaultDepth    24
        SubSection "Display"
                Depth           16
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
EndSection

                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
EndSection
Section "Screen"
        Identifier      "Screen2"
        Device          "ati"
        Monitor         "Acer AL1711-2"
        DefaultDepth    24
        SubSection "Display"
                Depth           16
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
EndSection
Section "Screen"
        Identifier      "Screen3"
        Device          "ati-1"
        Monitor         "Acer AL1711-3"
        DefaultDepth    24
        SubSection "Display"
                Depth           16
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
EndSection

最後是ServerLayout,

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen  0       "Screen0" 0 0
        Screen  1       "Screen1" RightOf "Screen0"
        Screen  2       "Screen1" RightOf "Screen1"
        Screen  3       "Screen1" RightOf "Screen2"
        Option          "Xinerama" "on"
        Option          "Clone" "off"
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"
        InputDevice     "stylus" "SendCoreEvents"
        InputDevice     "cursor" "SendCoreEvents"
        InputDevice     "eraser" "SendCoreEvents"
EndSection

這樣就大功告成了, 只是我現在手邊只有兩個monitor, 下次再拿兩個來指揮艇組合.
