A quick Google shows that laptop having integrated Intel graphics which can be a problem.  Try getting the latest drivers from HP:

GEM is going to be pretty painful on that laptop no matter what.

The laptop of one of the students has a problem rendering in GEM.
To reproduce the problem, all I have to do is to make a patch that
contains nothing but one [gemwin] and one [create, 1(. Click on the
message and the following error appears in the Pd window:

GEM: GLEW version 1.5.1
GEM: Start rendering
GL: invalid enumerant

When I make a basic pix_film player patch, the same error appears and
nothing is rendered in the GEM window.

I've searched the archives, but did not find anything useful to help
me find what causes this or how to solve this.

Any suggestions how to try to solve this are more then welcome :)

The machine is an HP 530, running WinXp and Pd-extended 0.42.5

Thanks

Rene
