hi all,
I'm new here.
I have similar problem with running a C project that uses GLUT/OpenGL graphics...


every run result with the two lines:

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

sometimes the graphics works ok sometimes there is an infinite loop, but every execution result with the two lines above.

what is the meaning of these 2 lines?
Is it an Error or Warning?
How can I fix the code?

My guess is that there is a fundamental problem with the graphics Glut Library...Or that I didn't write the MakeFile OK

Please help me, I would extremly appriciate it.

Are you running the program as root or normal user ?
I get that message with Suse if I try to run a program as root that starts the X server.
