Here at work, I am the only one interested into the new itools, yet
when running idl (linux) I get the following errors and the axis are
unreadable.
Did anyone have the same problem?
IDL> iplot,findgen(100)
% Loaded DLM: PNG.
% Compiled module: XMANAGER.
% Loaded DLM: IPTOOL.
% Compiled module: GET_SCREEN_SIZE.
% Compiled module: REVERSE.

% Compiled module: STRSPLIT.
% Compiled module: UNIQ.

Between this and the original error messages, I'm pretty sure that your
driver is broken with respect to texture mapping.
I would switch IDL to software rendering as I noted in my previous post and
start looking for driver fixes.
The only other thing that might be worth doing is to find a really simple
stand-alone OpenGL sample program that does texture mapping and see if that
runs. If it does not, then you have a simple test case that reproduces the
problem which is good to have if you report the problem to Matrox or whoever
is working on the drivers.

Oh, my gosh, when it rains, it pours. :-)
