求助：显示器分辨率问题

nhluqun · 发表于 2007-1-23 20:59:45

我装有windows2003和suse linux 10 desktop 双系统。显示卡为板载intel 82845G/GL芯片，显示器为acer19寸液晶显示器（刚换的），最大分辨率为1440x900 75Hz 在windows2003下正常显示，分辨率可以达到1600x900,比显示器最大分辨率还高？在suse linux 10.1 中也可认出是i845,也可以启动xgl,但是分辨率只有1280x768,而且不能再升高，也没有高分辨率的选项。字体有些糊糊。请问如何解决？谢谢了！
我的/etc/X11/xorg.conf如下。

没装驱动，装一下驱动就行了

nhluqun · 发表于 2007-1-24 09:24:50

我试过装显卡驱动的.到intel 网站中下了一个i845驱动程序包,解压后在没有启动Xwindows的情况下运行./setup安装,但好象有错误说不支持内核版本.装驱动失败.

nhluqun · 发表于 2007-1-24 18:09:20

下载了一个IntelGraphics_060704.tar.gz解压后得到dripkg目录,./install.sh之后出现2错误：AGPpart不能编译。kernel模块不能编译。

linuxahah · 发表于 2007-1-24 18:16:02

试试下面一条命令，并重启X。看看能不能调。
PS：我不确定这样好用，只是给个建议。

tmp1=`gtf 1440 900 75` ; tmp2=`cat /etc/X11/xorg.conf` ; echo "cat ${tmp2%%Section "Modes"*}Section "Modes"${tmp1}${tmp2##*Section "Modes"}" > /tmp/xorg.conf.new ; sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak ; sudo cp /tmp/xorg.conf.new /etc/X11/xorg.conf

复制代码

谢谢linuxahah!我试过,但是不行

invarcher · 发表于 2007-1-27 10:27:19

是不是没有安装kernel-source呀

bigbighill · 发表于 2007-1-27 11:28:30

我也是这种板载显卡，intel官方的那个不行，好像有一个第三方的驱动，当时我也编译安装了，后来我测试了好像还不如suse自动安装的显卡驱动呢（也许安装的不是很正确！），这种显卡我重来没有想过要开启xgl

马大瞎子 · 发表于 2007-1-27 12:58:24

SUSE对显卡、显示器这块的检测上都比较“变态”，俺有台14的HP显示器装了SUSE10.1后默认分辨率居然是1024*768，闪得死人。折腾N久后发现其实用不着驱动啊、X11下面改文件啊什么的。最简单的办法是在SAX2中手工降低显示器的同步频率，俺有台ViewSonic的G76f+就这样，把最高同步频率（水平和纵向）同步下降10％左右就好了。这个对显示器本身来说没有任何损伤，建议LZ试试。

nhluqun · 发表于 2007-1-27 15:24:22

已经安装了内核source了，今天在重新编译内核（第一次），慢啊！我的显卡可以打开3D和xgl,效果还好，现在最大的问题是分辨率上不去，原来那台14寸显示器，这个分辨率足够了，但换了19寸后，字体不太清。sax2中显示器型号没有我的这种类型。左试右试都不行。
