But if I try to launch alsaplayer (with gtk interface) like this: nice -n-5 alsaplayer my redhat 8.0 + planet ccrma packages says: ------ Gtk-WARNING **: This process is currently running setuid or setgid. This is not a supported use of GTK+. You must create a helper program instead. For further details, see: http://www.gtk.org/setuid.html Refusing to initialize GTK+ ------ and the same for a kde app: nice -n-5 rosegarden gives this answer: ----- The KDE libraries are not designed to run with suid privileges. ----- But an app that is not linked with gtk or kde works: nice -n-5 nedit launches nedit and then gnome-system-monitor confirms that nedit runs with a nice value of -5 . Then, the idea is, as root, to do: mv /usr/bin/nedit /usr/bin/nedit.real and to make a new file called nedit, executable, with the text: nice -5 nedit.real and to put it in /usr/bin so the next time I launch nedit as a user, the real nedit will be launched with -5 nice value. So obviously it can be done, but gtk and kde don't like it :( gtk is suggesting that I should (ah yeah) create a helper instead, but the link (http://www.gtk.org/setuid.html) didn't help me alot. I'm trying something with renice, that is working very well. But I'm not a programmer, I don't know how to make a bash file with renice and pidof. I'm digging deeper. But if someone is enlightened and willing/has the time to help, please do :-) cheers GuyCLO~ ----------------------------------------------- #219055 http://counter.li.org ----------------------------------------------- http://perso.wanadoo.fr/guy.clotilde/index.html -----------------------------------------------
