thanks ... man page was a bit confusing, but now i can see my invisible cursor
where do i have to set the new cursor theme?
i use /usr/X11R6/lib/X11/icons/default/index.theme
it seems to work till the screen turns black (screensaver), after that i have the default big black X in the middle of my screen ...
where is the default cursor theme (with my lovely big black X) located?
