[PyMOL] Re: Screen problem - G3 Powerbook - external display [Mac OS X 10.2.1]

[Kersey B. <kb...@js...>]

Hi all,

I posted a few days ago about a screen problem I was having.  In short 
form it was that the color map was getting screwed up when trying to 
drive an external monitor (though that was not specified in the 
original note), even with mirroring, even with all possible 
combinations of color profile settings, and even at relatively low 
resolutions.
I am doing this on a 400 MHz G3 Powerbook, which has 8 (non-upgradable) 
MB of VRAM.
I have seen a couple of flaky behaviors before which probably relate to 
this limitation in hardware, though for all but a couple of things, 
including PyMOL, driving an external display generally works fine.
None the less, this problem potentially restricts my ability to use 
PyMOL interactively in presentations.

Warren came up with a fix that seems to be working!
Thus, instead of writing back to him alone with thanks for his time, I 
thought I would post this
fix for others who may encounter the same problem, and save him having 
to answer this query in the future (or at least reduce that load).

And I quote ...

I added this to a script and all seems to be well.  I will let you know 
if that changes.

Thanks again

Cheers,
Kersey
