在X86，sparc 下的命令不同：

X86   用kdmconfig

sparc   用fbconfig

我的機子無法 在圖形界面設置分辨率，所以就搜了一下，以下是sparc 機子上如何命令行里設置分辨率；

在Solaris下更改分辨率是比較麻煩的  但大概的步驟可以如下：

常用的命令有：

ffbconfig,fbconfig,m64config

確定系統顯卡類型：

# cd /dev/fbs; ls –l

確定系統有多少塊顯卡

# fbconfig -list

  Device-Filename              Specific Config Program

  ---------------              -----------------------

  /dev/fbs/m640                SUNWm64_config

   /dev/fbs/ifb0                SUNWifb_config

確定系統顯卡支持的分辨率

# fbconfig -dev /dev/fbs/ifb0 -res /?

Valid values for -res option are:

        NONE

        1024x768x60

        1024x768x70

        1024x768x75

        1024x768x77

        1024x800x84 [1]

確定現顯卡的分辨率

# 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啟，只要重新 logout/login 就行了。
