[yast-devel] Changing (all) desktop files ...
I just stumbled over this bug report: https://bugzilla.novell.com/show_bug.cgi?id=540627 #### snip ############################################ All YaST .destop files in /usr/share/applications/YaST2 use the "X-KDE-SubstituteUID" to make them running as root. X-KDE-SubstituteUID is a KDE only "workaround" for that only KDE is supposed to be able to understand. Really, also GNOME as very famous DE understand that. All the others DE like XFCE, LXDE, Icewm and so on do not understand that (and they are not supposed to do that) so they run all yast2 modules as NON root user. all that Desktop files should edit their exec line and maybe remove X-KDE-SubstituteUID exactly as has been done with /usr/share/applications/YaST.desktop into yast2-control-center package. #### snap ############################################ Any comment or solution for this problem? What consequences does it might have if we changed all desktop files? Ciao, Daniel -- J.

You did not mention the actual fix: using xdg-su -X-KDE-SubstituteUID=true -Exec=/sbin/yast2 +Exec=/usr/bin/xdg-su -c /sbin/yast2

We would have to resubmit nearly all yast packages. Why don't the desktops implement X-KDE-SubstituteUID instead. -- Martin Vidner, YaST developer http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

You did not mention a consequence of your actual fix: YaST must additionally require the xdg-utils RPM. At least on my openSUSE 11.1 system, "rpm -q --whatrequires xdg-utils" does not show a YaST package.

Yes, indeed, that is how Qt4 control center does it atm.

It would enable YaST modules to be run as root e.g. from the menu or from the shortcut on user's desktop independently of DE. This is possible because xdg-su wrapper script figures out which *-su (kdesu, gnomesu) to call and if none of these can be used, prompts for root passwd in xterm.
Why don't the desktops implement X-KDE-SubstituteUID instead.
Because they are not required to. Freedesktop standard[1] states the following: "If one particular party wishes to add a field for personal use, they should prefix the key with the string X-PRODUCT, e.g. X-NewDesktop-Foo, following the precedent set by other IETF and RFC standards." In other words, X-PRODUCT (in this case X-KDE) is intended for the use by and within PRODUCT, e.g. RedHat applications do not have to read X-SuSE- prefixed desktop entries ;-) Now for this particular situation: Afaik, none of lightweight DEs - xfce, icewm, lxde,..- reads and understands X-KDE-SubstituteUID. Even upstream GNOME does not honour it (our GNOME does, due to SUSE-specific patch). As a result, YaST modules can't be launched from menu or desktop as root, if user's DE is other than KDE or GNOME hB.
