俺也是
sudo ddcprobe | grep monitorrange
没有显示什么出来
而且 /etc/X11/xorg.conf 文件改后也没效果
显卡驱动已经安装好
sudo ddcprobe | grep monitorrange
没有显示什么出来
而且 /etc/X11/xorg.conf 文件改后也没效果

Re: HOWTO:如何调整屏幕分辨率和刷新率
好帖!!!默认60的刷新有点闪
我只改了HorizSync 30-81 VertRefresh 56-75两项为32-70 50-120 BenQ的,新手注意牌子可以不改,我改过不能进图形界面,又cp回来

jazzi 写了:1。首先,确保手上有显示器的相关参数
没有说明书可查的话可以用下面这个命令查看2。备份Xorg.conf代码: 全选
sudo ddcprobe | grep monitorrange
3。添加你所需的分辨率和刷新率代码: 全选
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup
a.找到Section "Monitor"代码: 全选
sudo gedit /etc/X11/xorg.conf
这里,根据你显示器的型号改好,相关的信息可以从网上或者说明书里找到,我的是这样:
Section "Monitor"
Identifier "Sumsang 913N"
Option "DPMS"
HorizSync 30-81
VertRefresh 56-75
(这里我就是手动输入了显示器的型号和两个刷新频率)
b.找到下面Section "Screen"
根据需要,我只是改了最后两项SubSection,16位深和24位深:
SubSection "Display"
Depth 16
Modes "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
EndSubSection
我只是加入了原先没有的1280x1024的分辨率,要是愿意,你也可以改1,4,8,15位色深时的分辩率。保存,然后重启你的Ubuntu,应该就搞定了,还有别忘了按下显示器的AUTO键,让它自动设好最佳效果。
这时候,你会发现桌面的壁纸需要换成1280x1024的,然后,应该没有什么问题了,enjoy it!

关于ddc 的问题,我也整理了下,见这个帖子:
viewtopic.php?t=69241
What is DDC?
Short for Display Data Channel, a VESA standard for communication between a monitor and a video adapter. Using DDC, a monitor can inform the video card about its properties, such as maximum resolution and color depth. The video card can then use this information to ensure that the user is presented with valid options for configuring the display.
显卡DDC功能正常的情况下,可用sudo ddcprobe | grep monitorrange 命令查看显示器参数,一般live cd 启动后自动生成的xorg.conf应该包含有正确的显示器工作参数
显卡DDC功能不正常或显示器不提供DDC功能,则以显示器说明书或显示器后面的铭牌为准来修改xorg.conf

搞不定呀,修改了没反应!其它像1600*1200的分辨率有,少1440*900
