At times when I have seen this DISPLAY error for :0.0 I've had luck with

setenv DISPLAY machine-name:1  (csh example)

The GDPLOT2 input doesn't exist in the grid file.  when I run into this, I use 
GDLIST to check that the grids to plot are available.  Run the same input

> GDFILE   = /opt/gempak/GEMPAK7/desktop/cosmo.gem
> GDATTIM  = LAST
> GLEVEL   = 500
> GVCORD   = PRES
> GDPFUN   = TMPC

in GDINFO to see.  From the Cosmo grib2 that I sent me earlier, I see 329 grids 
but not any grids are PRES=500 for GVCORD.  I've attached a text file of the 
Cosmo grid contents, where you'll see many HYBL (hybrid) layers and some NONE 
(surface) layers but nothing for PRES.  so then the question becomes, does this 
model, or this model file (in grib) supply fields at 500mb, and it's that they 
are not being decoded correctly, or do they just not exist in the grib files?  
(I'm asking because I'm not familiar with the Cosmo model or how you are using 
it within your organization).
