設定Ubuntu 8.10 螢幕解析度
以前灌好Ubuntu之後,可以在System>Pref中找到螢幕,先將螢幕改成LCD就可以調整解析度了,現在8.10中,找不到了,
所以要調整解析度,就要透過手動的方式,否則就算安裝好顯卡的驅動程式也是不能調整解析度
1. 安裝顯卡驅動程式
到 系統->管理->硬體驅動程式
先將顯卡裝好
1. 備份xorg.conf
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
2. 修改xorg.conf
sudo gedit /etc/X11/xorg.conf
3. 在xorg.conf中加入下面幾行
特別是垂直及水平掃描率,當這兩個都設定好了,才可設定調整解析度
Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 22-82
VertRefresh 56-76
Option "DPMS"
EndSection
4. 以下是完整的設定檔
