Simultaneously displaying Images with different depths
I read this about Solaris and I have tested this on Sun Solaris with Elite 3D Video card.
"The Solaris X server supports devices that can display windows of more than one pixel depth simultaneously. These devices are called multi-depth devices. Since most of these devices are implemented with separate groups of bit planes for each depth, the term multiple plane group (MPG) device is often used for these devices."
What i did was i set the screen depth to 8-bits, and then i displayed a 24-bit image. The image was successfully displayed in 24 bit colors.
Now when i try doing this on my Redhat Linux 7.3 (on 1.7GHz P4, Graphic card NVidia GeForce2 MX/MX400) using the "xwud" utility, an error message is generated
"xwud: Error => Visual type is not large enough to hold all colors of the image."
Similarly in 24-bit mode when i try to display an 8-bit image, the image is displayed but everything in the background changes its color. The background color become normal when i close the image or unselect it.
Can anyone tell me what is wrong and how can i fix this problem. Is this the limitation of Linux X Server or my Graphic Card.
