Could not execute auto check for display colors using command

 Hi,

I am installing an agent on Solaris, when  uninstall the old agent, I get the following error message

I'm connecting from a remote server to another:

Could not execute auto check for display colors using command /usr/openwin/bin/xdpyinfo. Check if the DISPLAY variable is set.    Failed <<<<

Checking swap space: must be greater than 500 MB.   Actual 36864 MB    Passed

    >>> Could not execute auto check for display colors using command /usr/openwin/bin/xdpyinfo.

 Check if the DISPLAY variable is set.
