As I got no answer, I have digged into the source code.
At first: It's not KDE who tries to autodetect, but HAL. HAL uses "pm-utils" to
do all this "standby"-stuff, but it *doesn't* help to just uninstall pm-utils...
This is the code, used by HAL, to communicate with pm-utils:
http://cgit.freedesktop.org/hal/plain/tools/hal-system-power-pm-is-supported.c
And if we have a look at the "g_spawn_command_line_sync"-lines and the
GNOME-documentation for this:
<http://library.gnome.org/devel/glib/unstable/glib-Spawning-Processes.html#g-spawn-command-line-sync>
then we see, that they don't check the return value and just set "error" (last
parameter) to "NULL". This means, that a non-existent pm-utils makes this code
report that all ways of standby are supported...
The only way to really get rid of this stuff is to make sure
/usr/bin/pm-is-supported exists and always returns an exit code of one. So the
steps to get rid of sleep/hibernate are:
1. Uninstall pm-utils. You won't need them if you don't plan to use
sleep/hibernate. This makes sure that a possible update of this package
doesn't overwrite our "pm-is-supported"-replacement.
2. Run the following command to symlink between /bin/false and pm-is-supported:
# ln -s /bin/false /usr/bin/pm-is-supported
Yours
Manuel
