RHEL 6 – X Window 設定檔

突然同事問我 RHEL6 的 X11 的設定檔放那裏？阿!!不就是在 /etc/X11/xorg.conf 嗎?? 結果仔細看真的沒這一個檔,我們需要手動產生,執行 #Xorg -configure 就可以產生 xorg.conf 了!!!

[root@localhost ~]$ Xorg -configure

Xorg detected your mouse at device /dev/input/mice.
Please check your config if the mouse is still not
operational, as by default Xorg tries to autodetect
the protocol.

Your xorg.conf file is /root/xorg.conf.new

To test the server, run 'X -config /root/xorg.conf.new'

(EE) Server terminated with error (2). Closing log file.

Xorg 會顯示目前他有支援的 VGA 驅動模組.並且自行偵測你的系統可以使用哪一種模組,新產生的設定檔 xorg.conf.new 會儲存在家目錄,我們需要把該檔案從家目錄 xorg.conf.new 複製到 /etc/X11 ,如果偵測錯誤,可依據下面支援列表中自行編輯成目前系統的 VGA 的驅動模組.

常見的 Xorg 驅動程式名稱.

• qxl (QEMU QXL video accelerator)
• ati
• intel
• sisusb
• mga
• r128
• radeon (Driver for ATI/AMD Radeon)
• modesetting (Kernel Mode Setting)
• trident
• spiceqxl
• cirrus
• savage
• sis
• nouveau (Nvidia 的顯示卡)
• siliconmotion
• mach64
• tdfx
• vmware
• openchrome
• s3
• neomagic
• vesa (VESA-compatible)
• fbdev (Linux framebuffer X)
• v4l (old Xv ddx driver for video4linux devices)

最常指定使用的 xorg driver 驅動程式為 vesa,而且只要是 VESA-compatible video cards 都可以使用.或是 fbdev (Linux framebuffer X 驅動程式).

修改後就可以啟動 X-window

[root@localhost ~]$ cp xorg.conf.new /etc/X11/xorg.conf
[root@localhost ~]$ vi /etc/X11/xorg.conf
Section "Device"
        Identifier  "Card0"
        Driver      "fbdev"
        BusID       "PCI:0:15:0"
EndSection
[root@localhost ~]$ startx

如果可以進入 X-Windows ,這個 VGA 的驅動模組就確定可以在你的系統上來使用.
