915resolution修改屏幕分辨率

dieken_qfz

我的DELL 630m, windows下DELL有驱动可以设置到1280x800分辨率,
不过是在系统启动后修改的, 会导致屏幕闪一下. 昨天在Ubuntu Dapper
Beta上用915resolution修改了一下, 因为是在X启动之前修改的, 所以
屏幕没有闪, 修改后屏幕看起来舒服多了, 字体笔画都细了很多, 就是粗体
看起来有点毛糙.

修改前最好看一下/var/log/Xorg.log.0, 这里面有提示说屏幕的分辨率
是多少, 我的板子是1280x800的. 奇怪的是修改前配置Xorg时有选中
1280x800的分辨率可就是上不去.

用Dapper的可以直接aptitude install 915resolution, 我这里从
debian主页找了一段描述来:

http://packages.debian.org/testing/x11/915resolution

915resolution is a tool to modify the video BIOS of the 800 and 900 series Intel graphics chipsets. This includes the 845G, 855G, and 865G chipsets, as well as 915G, 915GM, and 945G chipsets. This modification is necessary to allow the display of certain graphics resolutions for an Xorg or XFree86 graphics server.

915resolution's modifications of the BIOS are transient. There is no risk of permanent modification of the BIOS. This also means that 915resolution must be run every time the computer boots inorder for it's changes to take effect. If you want to automatically set the resolution on each boot and before X is launched, see /usr/share/doc/915resolution/README.Debian for information about configuring the provided initscript.

#apt-get install 915resolution

编辑 /etc/default/915resolution

#
# 915resolution default
#
# find free modes by  /usr/sbin/915resolution -l
# and set it to MODE
#
MODE=7e
#
# and set resolutions for the mode.
#
XRESO=1280
YRESO=800
#
# We can also set the pixel mode.
# Please note that this is optional,
# you can also leave this value blank.

然后：
#/etc/init.d/915resolution start

$startx

一般都是用gdm登录的, 很少有人直接startx吧, 这个包自己带着有文档,
就是针对915GM有个例子,  不过那个READ.Debian感觉改得过火了,
分辨率调的那么高, 我怕会坏事, 就按照它原来的说明文档做的, 说的很详细.

改完之后重启一下机器, 简单省事, 也就等那么几分钟. 不想等也许可以
/etc/init.d/gdm restart吧.
