   After I installed Linux Red Hat 6 I tried to connect the server via vncserver.But I get
some error about 'xsetroot'.When I wanted to connect vnc,vnc start successfully but
there was an error in log file.I tried to solve this problem for two days;but I can't solve it.Then  I changed viewpoint.Sometimes we should change our viewpoint:))
