# xrandr Screen 0: minimum 8 x 8, current 2390 x 768, maximum 32767 x 32767 LVDS1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 277mm x 156mm 1366x768 60.1*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) HDMI3 disconnected (normal left inverted right x axis y axis) VGA1 connected 1024x768+1366+0 (normal left inverted right x axis y axis) 408mm x 255mm 1440x900 59.9 + 75.0 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 75.0 72.8 66.7 60.0 720x400 70.1 VIRTUAL1 disconnected (normal left inverted right x axis y axis) 1440x900_60.00 (0x1b4) 106.5MHz h: width 1440 start 1528 end 1672 total 1904 skew 0 clock 55.9KHz v: height 900 start 903 end 909 total 934 clock 59.9Hz # VGA1是外接显示器的硬件指标，可以看出最佳分辨率是1440x900

生成modeline

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

创建modeline

xrandr --newmode "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync

VGA1添加modeline

xrandr --addmode VGA1 "1440x900_60.00"

应用

xrandr --output VGA1 --mode "1440x900_60.00" posted on 2015-08-17 10:30 北京涛子 阅读( ...) 评论( ...) 编辑 收藏
