透過vnc安裝oracle出現at least 256 colors Failed的錯誤處理

1 出現錯誤如下：
Checking Temp space: must be greater than 250 MB. Actual 1570 MB Passed
Checking swap space: must be greater than 500 MB. Actual 1810 MB Passed
Checking monitor: must be configured to display at least 256 colors Failed >> Could not execute auto check for display colors using command /usr/openwin/bin/xdpyinfo. Check if the DISPLAY variable is set.
Some requirement checks failed. You must fulfill these requirements before
continuing with the installation,at which time they will be rechecked.
2 處理思路是修訂vncserver的配置為以下內容：
#!/bin/sh
/usr/openwin/bin/xrdb $HOME/.Xresources
/usr/openwin/bin/xsetroot -solid grey
/usr/openwin/bin/xterm -geometry 1024x768 -ls -title "$VNCDESKTOP Desktop" &
/usr/dt/bin/dtsession &
#startkde &
#/usr/bin/gnome-session &
#/usr/openwin/bin/twm &
#80x24+10+10 -depth 16 -geometry 1024x768 -rfbwait 120000 -rfbauth& 這裡是xterm行原來的配置
3 重新啟動vncserver後ok[@more@]透過vnc安裝oracle出現at least 256 colors Failed的錯誤處理
