[juneau-lug] Re: Linux Games Notes

Well, I got the pixel depths problem fixed.  That wasn't hardware, but 
just too few details in the XF86config-4 file that X set up for me. 
When I put in the same mode lines for each monitor, they both work the same.

That means that I can't do the test that you suggested.  In fact, I'm 
not sure that they were running at different pixel depths: the ugly, 
switching colors was happening on both, so I think that X just settled 
for the lowest common denominator.

I've opened the Gimp and displayed a picture across both monitors, and 
it looks pretty good.

The one remaining problem is that the colors are somewhat different on 
the two monitors.  I found out about xgamma, and have been experimenting 
with changing gamma, all at once and red, green and blue individually. 
So far, I can't make the two look the same.  I wish I could find a gamma 
GUI, so I could drag something about through the color space and see 
what it looks like.  On the new monitor, the white looks a little dirty, 
perhaps slightly tinged with red.  Unfortunately, turning the red down 
to almost zero doesn't seem to change that.

Anyway, that's not a huge problem, so I won't panic about it.
