And take care: vectorial export of a 3D scene can be slow.

Hi Calixte,
thank you very much for your comprehensive reply! Now I understand why
I must either install the proprietary driver (beware!) or use the
vectorial export. I will probably choose the latter when I want to
export a figure to be able to use it at my web site.
I just want to correct my code lines below:
f = scf(1);
should NOT be there, before
driver('PNG');
because then it didn't work!
Best regards
Stefan

Hi Stefan,
Few comments:
i) driver(...);xinit(...);...xend(); implies a vectorial export: all
the scene is completly drawn vectorialy (so the graphic card driver is
not implied in the draw)
ii) xs2png(0,...): a memory dump is done and the bitmap is converted
into PNG. The GC driver is called to retrieve the data and it seems
that this kind of bug is typical to Ubuntu with free driver... the
only workaround I know (for the moment ;)) is to switch to the
proprietary driver.

Hi Antoine,
are we supposed to reply above as earlier or not ;-(
When I did as you proposed:
x = [0:0.05*%pi:2*%pi]';
f = scf(1);
driver('PNG');
xinit('gridtest.png');
plot2d(x, sin(x))
xgrid()
xend();
driver('X11');
it was OK!

And, of course, thank you!

So, Calixte, it was not the graphics driver, was it? Shall I report
a bug?
Regards /Stefan
