This software changes the resolution of an available vbios mode. It is useful，when the native screen resolution isn't advertised as available by the video bios by default.

如果机器的分辨率上不去，或者调整好后，下次重启机器还得重新调整的，应该用这个工具来尝试调节；

二、安装和配置855resolution：

1、安装 855resolution

在Fedora Core 4.0 中，如果您通过yum 在线更新软件包，请您参考 《Fedora/Redhat 在线安装更新软件包，yum 篇》，来查看yum的使用方法和软件仓库；

[root@localhost beinan]# yum install 855resolution

在Fedora Core 4.0 中，如果您通过apt 在线更新软件包，请您参考 《用apt+synaptic 在线安装或升级Fedora core 4.0 软件包》，来查看 apt 的用法及软件仓库；

[root@localhost beinan]# apt-get install 855resolution
2、应用及配置 855resolution

855resolution 被安装在以下的目录中，所有的文件如下：

[root@localhost beinan]# rpm -ql 855resolution
/etc/rc.d/init.d/855resolution
/etc/sysconfig/855resolution
/usr/sbin/855resolution
/usr/share/doc/855resolution-0.4
/usr/share/doc/855resolution-0.4/CHANGES.txt
/usr/share/doc/855resolution-0.4/LICENSE.txt
/usr/share/doc/855resolution-0.4/README.txt

[root@localhost beinan]# 855resolution --help
855resolution version 0.4, by Alain Poirier
Usage: 855resolution [-p] [-l] [-f bios_type] [mode X Y]
  Set the resolution to XxY for mode
  Options:
    -l display the modes found into the vbios
    -f skip the VBIOS detection by forcing a VBIOS type
    -p display the registered plugins

首先我们列出vbios的模式：用 -l参数；

[root@localhost beinan]# 855resolution -l
855resolution version 0.4, by Alain Poirier
Chipset: 855GM (id=0x35808086)
VBIOS type: 2
VBIOS Version: 3360
Mode 30 : 640x480, 8 bits/pixel
Mode 32 : 800x600, 8 bits/pixel
Mode 34 : 1024x768, 8 bits/pixel
Mode 38 : 1280x1024, 8 bits/pixel
Mode 3a : 1600x1200, 8 bits/pixel
Mode 3c : 1920x1440, 8 bits/pixel
Mode 41 : 640x480, 16 bits/pixel
Mode 43 : 800x600, 16 bits/pixel
Mode 45 : 1024x768, 16 bits/pixel
Mode 49 : 1280x1024, 16 bits/pixel
Mode 4b : 1600x1200, 16 bits/pixel
Mode 4d : 1920x1440, 16 bits/pixel
Mode 50 : 640x480, 32 bits/pixel
Mode 52 : 800x600, 32 bits/pixel
Mode 54 : 1024x768, 32 bits/pixel
Mode 58 : 1280x1024, 32 bits/pixel
Mode 5a : 1600x1200, 32 bits/pixel
Mode 5c : 1920x1440, 32 bits/pixel
Mode 7c : 1280x768, 8 bits/pixel
Mode 7d : 1280x768, 16 bits/pixel
Mode 7e : 1280x768, 32 bits/pixel

通过上面列出的内容，比如我想让显示支持 1024x768 32 bits/pixel ，查看其Mode为 54 ；所以我们应该用855resolution来设置；
[root@localhost beinan]# 855resolution 54 1024 768

上面是命令行式的的配置，最好是改配置文件最方便；855resolution配置文件为/etc/sysconfig/855resolution ;
# Mode to overwrite (use "855resolution -l" to see all available modes)
MODE="54"
# Resolution to set (i.e. "1280 768", no "x", only a space as the separator)
RESOLUTION="1024 768"

改好后，重启 /etc/init.d/855resolution ，下次启动机器进入系统，就不必管他了，他是自行启动的服务；

[root@localhost beinan]# /etc/init.d/855resolution start
Overriding video bios mode 54 from 1024x768 to 1024x768: [ 确定 ]

另外还要修正/etc/X11/xorg.conf ；查看类似下面的一段；
