I though to broaden the audience in the hope to get advice.
I forgot to mention that
exec /usr/bin/X11/X -dpi 100 -nolisten tcp
Combined with the information below, I do not understand where <startkde> is
activated in order to prevent it being activated automatically. I normally
need X and window manager twm or mwm and kde is now an irritating
Following update/upgrade of debian 32 testing/unstable, <startx> launches in
rapid sequence X-system and kde.
Because I normally use the X-system for special applications, how to avoid
launching kde automatically?
I was unable to trace the config files
in my home directory. I thought to comment kde there.
Thanks a lot, sometimes one gets confused
