When I first installed X-Windows my colors worked fine. After I installed a window manager called AfterStep my colors started acting weird. Many of my programs are in black & white. And I get the following errors from xterm when I run X programs from it.

XView warning: Unable to allocate control colors for colormap segment (Color package)

Any ideaz?

This is caused by X running in 8 bits (256) color mode. A fast fix is to try to start X in 16 bits (65536) or 24 bits(lots) to do so you type:

startx -- -bpp 16

To fix in a more permanent way you'll have to edit the /etc/XF86Config in the screen section and add DefaultColorDepth 16 or 24


Section "Screen"
    Driver      "accel"
    Device      "WhateverCardYouHave"
    Monitor     "WhateverYourMonitorIsCalled"
    DefaultColorDepth 16
    Subsection "Display"
        Depth       8
        Modes       "640x480" "800x600" "1024x768" "1280x1024"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "640x480" "800x600" "1024x768"
        ViewPort    0 0
    EndSubsection
EndSection

Hope this help!

I forgot to mention why you had black and white. It is because X wasn't able to assign more colors.
