在X86，sparc 下的命令不同：
X86 用kdmconfig
sparc 用fbconfig
我的机子无法 在图形界面设置分辨率，所以就搜了一下，以下是sparc 机子上如何命令行里设置分辨率；
在Solaris下更改分辨率是比较麻烦的 但大概的步骤可以如下：
常用的命令有：
ffbconfig,fbconfig,m64config
确定系统显卡类型：
# cd /dev/fbs; ls –l
确定系统有多少块显卡
# fbconfig -list
Device-Filename Specific Config Program
--------------- -----------------------
/dev/fbs/m640 SUNWm64_config
/dev/fbs/ifb0 SUNWifb_config
确定系统显卡支持的分辨率
# fbconfig -dev /dev/fbs/ifb0 -res \?
Valid values for -res option are:
NONE
1024x768x60
1024x768x70
1024x768x75
1024x768x77
1024x800x84 [1]
……………………
确定现显卡的分辨率
# fbconfig -dev /dev/fbs/ifb0 -prconf

更改分辨率
bash-3.00# fbconfig -dev /dev/fbs/ifb0 -res 640x480x60
注：更改分辨率后不必要重启，只要重新 logout/login 就行了。
