Why Screen saver is white not black?

Why Screen saver is white not black?

Sorry for this question, I saw it before but I miss it.

Why My screen saver turn white instead of  black and how to set up the
default screen saver under X?

If I don't login as root, the modem is always lockup. How can I fix it?


1. Console-Screen-Blanking: black chars on white screen


I'm doing a lot of my work on the Linux console. Used to that good old
ASCII-Terminals I looked for a utility that would give me black
characters on a white screen. I found setpalette from Koen Gadeyne's
SVGATextMode-Packackage (thanks Koen). The following ioctl's along
with a proper setting of kernel_palette do the job:

    fd = opentty("/dev/console");
    if (ioctl(fd, GIO_CMAP, kernel_palette))
    if (ioctl(fd, PIO_CMAP, kernel_palette))

But there is one disadvantage: The routines for screen blanking simply
make everything show up with the background's color. This gives me a
blanked screen, which is really paperwhite :-(

Any hints ?
