Cannot Allocate Colormap Entry / Knowledge Base

Cannot Allocate Colormap

Issue	When I run any component of JExpress on my Linux machine, I see, "Warning: Cannot allocate colormap entry for default background".
Comments	You may see this Linux error message when you try to run a JExpress installer, or any other Java program that uses a graphic interface. It means that your XWindows configuration file, XF86Config, is misconfigured. The video display driver must have a default color depth of at least 16 bits. Remove any lines in the Monitor section that specify a shallower depth.
Status	Solved
Applies to	All
Platforms	Linux
Topics	colormap, XWindows, XF86Config
