Hi,
I am trying to run one display test through command line. I am getting the below error:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

To remove this error, i just switched to the UI mode and just logged in to that.
Then my test runs correctly.
Is there any way, i can do it without manually switching to the UI mode?
I tried to use xhost +localhost as root from command line too , but it give the following error:
xhost: unable to open display ""

Actually , i need to run this test on PXE server which doesnot contain UI mode?
Is it possible to do it on Command line without any console screen.

Needs Quick reply. It is urgent.
