sis显卡驱动

2008.3.14

最近换了台机器，显卡是sis661的，在Linux下显卡默认驱动不行，搞的屏幕乱闪，看的头晕。在网上搜索了一下，发现Linux下sis系列的显卡驱动太难找了，找到的也都是很旧的，下了sis sg86c225的和sis620的，驱动文件上的更新日期还是1999年（汗）感觉上应该还是驱动不了，不过还是试试看。

进入linux系统（ps:刚开始选错了显卡驱动，结果启动不了桌面系统了，这里可以通过command行修改/etc/x11/xorg.config，如果有备份，则可以直接选择恢复成原先备份的配置/etc/x11/xorg.config.bakeup就可以启动桌面界面了），可以有几种方式来查看和修改显示模式和驱动。

1、利用图形界面的显示选项，可以图形化配置显示的参数。
2、命令行形式，主要是利用xvidtune和xrandr命令，其中可以直接通过xrandr -s 1 -r 85来设置，我机子上这样配置以后是显示1024*768和85Hz。
3、/etc/x11/xorg.config的修改，好像这个才是问题的关键，其他方法也都会修改这个文件，不过没有仔细看。试了下sis sg86c225驱动，没有效果，sis 620驱动，可以用哦（虽然老点，能用就好），屏幕不闪了，驱动成功。配置后的xorg.config文件还是贴出来吧，虽然不是太清楚每句含义，不过大概可以查看到显示器和显卡的型号以及驱动等信息……

# RgbPath is the location of the RGB database.  Note, this is the name of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# Option "Xleds"  "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
