ubuntu優化問題 更改分辨率

1，選好自己適合分辨率，比如我的是1440×900, 終端運行：

cvt 1440 900

輸出：

1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHzModeline "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync

2把這個分辨率寫入配置文件：

命令：

	sudo vim  /etc/X11/xorg.conf      或
	sudo gedit  /etc/X11/xorg.conf

3把下述配置寫入文件：

Java代碼

Section "Monitor"  
Identifier "Configured Monitor"  
Modeline "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync  
Modeline "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync  
Option "PreferredMode" "1440x900_60.00"  
EndSection  
  
Section "Screen"  
Identifier "Default Screen"  
Monitor "Configured Monitor"  
Device "Configured Video Device"  
EndSection  
  
Section "Device"  
Identifier "Configured Video Device"  
EndSection
