gentoo好像不支持1920X1080分辨率－－（解决啦）

小楼东风

显示器三星f2380,xorg.conf已经设置为1920X1080，但是进入KDE居然是1600X1200，进入KDE没问题，应该只是xoeg.conf分辨率设置问题吧？或者内核要配置？

zhangmms

你的显卡支持么？看看Xorg.log

跟内核没关系。跟xorg.conf设置和显卡驱动有关系。

如果windows下正常的话，显卡应该是支持此分辨率的。

不知道xorg是不是支持。

xp下面没有问题，当是linux不行。sabayon4.2 liveDVD也不行。XP下面的显示器显示的参数为67.2khz，60hz，1920x1080。在xorg.cong里面设置这些参数还是1600x1200

看看行不行


~ $ gtf 1920 1080 60 也可以得到modeline


read-edid也是一个途径，用法是 ~ $ sudo get-edid | parse-edid

1. Option "noDDC" "True"
2. Option "UseEdid" "False"
3. Option "UseEdidDpi" "False"
4. Option "UseEdidFreqs" "False"
5. Option "ModeValidation" "NoEdidModes"

复制代码

或许这样的options也能解决问题



Xorg.0.log 也是要拿来对照参考的

最快捷的方法是 xrandr -s 1920 1080

怎么可能不支持,给你ModeLine参考下

    ModeLine "1920x1080@24" 74.250 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync
    Modeline "1920x1080@50" 148.500 1920 2448 2492 2640 1080 1084 1089 1125 +hsync +vsync
    Modeline "1920x1080@60" 148.350 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync

不过我是N卡,实在不行,你去下载个XBMC的Live版刻盘或者U盘量产启动看看行不行

可以了，谢谢各位！
xrandr -s 1920x1080好像不行。执行和显示
