[Gnuplot-info] Problems with my gnuplot...

[Gonzalo V. R. <gvi...@gm...>]

Hi, my name is Gonzalo Vilella. I'm writing you because I've got some
problems with my gnuplot for Kubuntu. I had the 4.0 version and I
tried to ugrade it to the 4.2 version. It told me to install the x-11
package. Once I did that, it has started failing. Now, every once I
try to execute the gnuplot I have a problem: it says:

Terminal type set to 'x11'
gnuplot> Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


gnuplot: unable to open display ':0'
gnuplot: X11 aborted.


Since I'm not very keen on Linux or computer sciences, I don't know
how to solve this. If you could help me...

Thank you very much, and forgive my poor English (I'm a spanish boy...)
