Comment (by dylan):

 Some updates (2008-03-26 SVN) & "nvidia" driver with DRI/GLX enabled.

 1. export to full-res PPM, no error messages but results in black image.

 Final Assembled Image will be 3185 x 4096

 Assembling Tiles
 Destroy pbuffer
 ------------------------------------------


 2. set env. variables:
 export GRASS_NO_GLX_PIXMAPS=TRUE
 export GRASS_NO_GLX_PBUFFERS=TRUE

 export to full-res PPM, resulting image is at the coarse grid resolution.
 After setting the coarse resolution to 1 and the fine resolution to 1 the
 output file appears to be correct.
 ------------------------------------------
 Final Assembled Image will be 3909 x 4096

 It seems like Glynn's recent changes + setting environmental variables is
 the trick to getting things to work using the "nvidia" driver.
