Ubuntu 12.10。 无法添加自定义分辨率
系统：Ubuntu 12.10，nVidia Geforce GT240（nvidia-current privative driver），LG显示器连接到VGA-0
没有列出1920×1080分辨率，我已经在Windows中添加了它，但我在使用相同的Ubuntu时遇到了问题。
步骤1）获取模式
$ 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
Screen 0: minimum 8 x 8, current 1152 x 864, maximum 8192 x 8192 VGA-0 connected 1152x864+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0 + 1360x768 60.0 59.8 1152x864 60.0* 800x600 72.2 60.3 56.2 680x384 119.9 119.6 640x480 59.9 512x384 120.0 400x300 144.4 320x240 120.1 DVI-I-0 disconnected (normal left inverted right x axis y axis) DVI-I-1 disconnected (normal left inverted right x axis y axis) HDMI-0 disconnected (normal left inverted right x axis y axis) 1080p (0x2f7) 172.8MHz h: width 1920 start 2040 end 2248 total 2576 skew 0 clock 67.1KHz v: height 1080 start 1081 end 1084 total 1118 clock 60.0Hz
难道我做错了什么？
好的，这对我有用。
1）编辑/etc/X11/xorg.conf
2）在“监视器”部分中，将HorizSync和VertRefresh更改为正确的值（请参阅用户手册中的监视器规格）。 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并从控制台编辑xorg.conf ）。
Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "CRT-0" HorizSync 30.0 - 83.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection
3）在“屏幕”部分添加此行。
Option "ModeValidation" "AllowNonEdidModes, NoVirtualSizeCheck, NoMaxPClkCheck, NoWidthAlignmentCheck, NoExtendedGpuCapabilitiesCheck"
4）重启系统。
5） xrandr –addmode仍然不起作用，但你会有更多的分辨率。 看看我的新xrandr输出：
