Ubuntu 12.10. 无法添加自定义分辨率

系统：Ubuntu 12.10、nVidia Geforce GT240（nvidia-current privative 驱动程序）、LG 显示器连接到 VGA-0

没有列出 1920x1080 分辨率，我已在 Windows 中添加了它，但在执行相同的 Ubuntu 时遇到了问题。

步骤 1）获取 modeline

$ cvt 1920 1080

步骤 2）创建自定义模式

$ xrandr --newmode "1080p"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync

步骤 3）添加自定义模式

$ xrandr --addmode VGA-0 "1080p"

然后我收到这个错误：

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  29
  Current serial number in output stream:  30

xrandr 输出是

        v: height 1080 start 1081 end 1084 total 1118           clock   60.0Hz

难道我做错了什么？

答案1

好的，这对我有用。

1）编辑/etc/X11/xorg.conf

2）在部分“监视器”， 改变水平同步和垂直刷新设置为正确的值（请参阅用户手册中的显示器规格）。这很重要，否则您的显示器可能会出现“信号超出范围/同步”错误（如果您犯了这个错误，请按 ctr+alt+f1 并编辑xorg配置文件从控制台）。

Section "Monitor"

    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "CRT-0"
    HorizSync       30.0 - 83.0
    VertRefresh     56.0 - 75.0
    Option         "DPMS"
EndSection

3）在部分“屏幕”添加此行。

Option "ModeValidation" "AllowNonEdidModes, NoVirtualSizeCheck, NoMaxPClkCheck, NoWidthAlignmentCheck, NoExtendedGpuCapabilitiesCheck"

4）重新启动系统。

5）xrandr——添加模式仍然无法使用，但您将有更多分辨率可用。查看我的新兰德输出：
