<p>This driver release supports X screens with screen depths of 30
bits per pixel (10 bits per color component). This provides about 1
billion possible colors, allowing for higher color precision and
smoother gradients.</p>
<p>When displaying a depth 30 image, the color data may be dithered
to lower bit depths, depending on the capabilities of the display
device and how it is connected to the GPU. Some devices connected
via analog VGA or DisplayPort can display the full 10 bit range of
colors. Devices connected via DVI or HDMI, as well as laptop
internal panels connected via LVDS, will be dithered to 8 or 6 bits
per pixel.</p>
<p>To work reliably, depth 30 requires X.Org 7.3 or higher and
pixman 0.11.6 or higher.</p>
<p>In addition to the above software requirements, many X
applications and toolkits do not understand depth 30 visuals as of
this writing. Some programs may work correctly, some may work but
display incorrect colors, and some may simply fail to run. In
particular, many OpenGL applications request 8 bits of alpha when
searching for FBConfigs. Since depth 30 visuals have only 2 bits of
alpha, no suitable FBConfigs will be found and such applications
will fail to start.</p>
