There's color depth, and there's bits per pixel. Bits per pixel is how many bits of memory a pixel consumes. Color depth is how many of those bits are used to represent color information. Color depth <= bits per pixel, always. The normal format we choose is depth 24, 32bpp. You can also do depth 24, 24bpp, but it's usually much slower since 3/4's of your pixels will now require unaligned memory accesses. But there's literally no depth 32 format in the X server. All of which is sort of besides the point: your monitor never sees any of this. If it's VGA, then you're just wiggling analog pins, and the color depth just reflects the precision with which the pins are wiggled. If it's a digital connector like DVI-D or laptop-internal LVDS, then the DVI transmitter pads the color information out to eight bits per color channel anyway. So what you actually found was a bug in which we appear to program the monitor _timings_ wrong in 16bpp, but not in 32bpp. That's actually quite interesting, and I would greatly appreciate it if you would file a bug report with the X logs (/var/log/Xorg.0.log) from attempting to start at both 16 and 32bpp. - ajax -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
