hey all,

i have a curious problem. basicly, my kdm background is set to black
and to auto-login, and my kde desktop background is set to black, so i
should go from "black to black". however, it would appear that when
kde starts, it has a blue background and displays it until it starts
loading my personalised settings, leading to a "black to blue to
black".

i cant imagine this would be too hard to solve, but i cant seem to
find anything about where this colour setting is stored and nothing in
the gui seems to change it.

is it possible to change this default kde background colour?

i should point out, i certainly dont mind getting my hands dirty
delving around in configuration files if required.

just incase it is helpfull, i am using kubuntu 7.10 on a toshiba
equium a200-1v0 and everything is working perfectly except for this
little blue flash when kde is loading.

IIUC, you have set your desktop background to black, and you think that
you have set the KDM background to black.

It isn't that simple: sorry about that. :-)

There is an X command option which I think is "-br" which substitutes a
startup black root window background for the standard 1 pixel pitch gray
checkerboard. With KDM, this is set in: $KDEDIR/share/config/kdm/kdmrc:

ServerCmd=

Then there is the background color for KDM which is set in the Control
Center:

System Administration -> Login Manager :: Background

Then the: "$KDEDIR/bin/startkde" script might be setting the background:

xsetroot -solid <color>

and you probably want to simply remove that, but don't remove:

xsetroot -cursor_name left_ptr

And then finally there is the Desktop background in the Control Center:

Appearance & Themes -> Background

And then there are utilities such as xloadimage that can also set the
root background color.

Thankyou for your very quick and informative answer, it was exactly
what i was looking for :) it turns out it was the startkde script
that had the colour set, one quick edit and no more blue flash.

i'm not sure if it is usefull to others or not, but just in case, here
is the problem and solution.

using ubuntu 7.10, the file /usr/bin/startkde contains the following section

-- copied from /usr/bin/startkde --

# Set the background to plain grey.
# The standard X background is nasty, causing moire effects and exploding
# people's heads. We use colours from the standard KDE palette for those with
# palettised displays.

if test -z "$XDM_MANAGED" || echo "$XDM_MANAGED" | grep ",auto" >
/dev/null; then
xsetroot -solid "#618DCC"
fi

-- end of copy --

i edited the file as root using the command "sudo nano
/usr/bin/startkde" to set the colour to #000000 (hex black) so i get
the black background i wanted without having to see x's default "head
exploding" grey dotted background.

-- updated /usr/bin/startkde --

# Set the background to plain grey.
# The standard X background is nasty, causing moire effects and exploding
# people's heads. We use colours from the standard KDE palette for those with
# palettised displays.

#change inserted here by me
#changed solid colour from 618dcc to 000000

if test -z "$XDM_MANAGED" || echo "$XDM_MANAGED" | grep ",auto" >
/dev/null; then
xsetroot -solid "#000000"
fi

-- end of copy --

and now i have a very shiny black background from startup to desktop.

thankyou for your quick and informative help, what seemed a difficult
problem has suddenly become easy :)
