Gnuplot not plotting, error message: Could not connect to existing gnu

Hey guys,

I apologize if this has been posted before. I did a search and couldn't find anything, but sometimes I miss things.

I have not used gnuplot for a while and have recently tried plotting with it again. After a ~5-10 second delay after running a simple plot command, I receive the following error:

Could not connect to existing gnuplot_qt. Starting a new one.

Warning: slow font initialization

I am not sure what might have caused this, but if any of you guys have ideas, I am all ears!

I have gnuplot 5.0 patchlevel 4, if it helps

Thanks!

Everything is working fine here. This is with the standard gnuplotrc and no .gnuplot. So maybe you should check those two files first for possible problems. Maybe also check if /usr/bin/gnuplot_qt is correctly installed.

$ gnuplot

I could not quite find the issue but using

 set terminal x11

Will do the trick for now (in case someone comes across this thread through helpless googling).
