NVidia驱动程序后的错误解决方案

我在使用NVidia驱动程序时遇到了一些问题。 当我安装Ubuntu 14.04时,屏幕分辨率无法检测模式1280×1024。 我使用xrandr创建了1280 x 1024模式。 安装NVidia驱动程序后,我无法将分辨率设置为1280×1024。 检测到错误的分辨率。

如果我运行xrandr:

Screen 0: minimum 8 x 8, current 1152 x 864, maximum 8192 x 8192 DVI-I-0 connected primary 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 60.0 59.8 640x480 59.9 512x384 60.0 400x300 72.2 320x240 60.1 DVI-I-1 disconnected (normal left inverted right x axis y axis) TV-0 disconnected (normal left inverted right x axis y axis) DVI-I-2 disconnected (normal left inverted right x axis y axis) DVI-I-3 disconnected (normal left inverted right x axis y axis) 1280x1024_60 (0x26f) 108.0MHz h: width 1280 start 1344 end 1456 total 1688 skew 0 clock 64.0KHz v: height 1024 start 1025 end 1028 total 1066 clock 60.0Hz 1280x1024_60.00 (0x27a) 108.9MHz h: width 1280 start 1360 end 1496 total 1712 skew 0 clock 63.6KHz v: height 1024 start 1025 end 1028 total 1060 clock 60.0Hz 1280x1024_75.00 (0x27d) 138.5MHz h: width 1280 start 1368 end 1504 total 1728 skew 0 clock 80.2KHz v: height 1024 start 1025 end 1028 total 1069 clock 75.0Hz 1280x1024_59.00 (0x27f) 107.0MHz h: width 1280 start 1360 end 1496 total 1712 skew 0 clock 62.5KHz v: height 1024 start 1025 end 1028 total 1059 

当我尝试添加新模式时:

 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: 31 Current serial number in output stream: 32 

我的连接不是DVI,因为我使用适配器到D-sub。

你可以尝试这个,打开这个文件

 sudo gedit /etc/X11/xorg.conf 

并将此行添加到设备部分

 Option"ModeValidation" "NoMaxPClkCheck" 

然后重启
