Description Scott Jackson 2004-08-17 20:50:20 UTC
I'm using the xorg-x11 ebuild from gentoo, using a fresh move from XFree86, but
the colormaps don't seem to work correctly, nor does alphablending. Colors are
displayed incorrectly, and I can't run GL apps because 
"Error: couldn't get an RGB, Double-buffered visual"
Nobody on the IRC channel seems to know about this issue, but attached I have a
sample screenshot which I think is alright, but I can't look at it correctly due
to colormap problems.
Also attached is my xorg.conf.

I've also noticed that when loading images in image magick, it takes a
significant amount longer to load the program, and the CPU load coasts at 99%
for approx. 10-20 times as long as it should take to load the image.
Comment 4 Adam Jackson 2004-08-17 21:04:24 UTC
could you attach your X log too?

you don't specify a DefaultDepth in your Screen section; are you sure you're not
in 8bpp mode?  converting that screenshot to 256-color indexed mode looks nearly
identical (allowing for jpeg artifacts).
Comment 5 Scott Jackson 2004-08-17 21:08:46 UTC
Found the problem, NOT RESOLVED
problem is in xorgcfg,
I had to set the DefaultDepth in the config file, but xorgcfg should have done
that for me!

Mass reopen.  The "REMIND" resolution is lame, I'm deleting it.  Consider yourself reminded.
Comment 7 Aaron Plattner 2008-04-21 10:16:03 UTC
This should long be resolved.  The server switched the default to depth 24 ages ago.
