I'm not so sure. If the session manager parents fvwm2 with a legitimate $DISPLAY value already set (like :0.1), ignoring it and setting $DISPLAY anyway seems risky, especially since Xlib _may_ tell fvwm2 that display is "unix:0.1". It seems to me _any_ window manager should attempt to use the display handed to it if possible (either inherited through $DISPLAY or hardwired via command line option), to keep the wm in sync with the session manager's other children. > > Just for a curious, what is your setup? > > Real session manager and multi-screen display? > > How do you restart, using which command on which screen? > I am running a two-headed display under Solaris 7's dtsession (not Xinerama). At login, twin instances of the default window manager are started. I bring up an xterm on the right screen (:0.1) and kill the right-side wm instance. In that same window, I start fvwm2 manually: % /<path>/fvwm2 -s -f /<path>/<config_file> I am able to recreate the problem with this minimalist <config_file>: ModulePath /<path>/modules:+ AddToFunc StartFunction + I Echo $[DISPLAY] + I FvwmTaskBar + I FvwmCommandS On startup, I always see in the xterm: [FVWM.1][Echo]: :0.1 I restart using fvwm2's built-in root menu on the right screen. Sometimes on the first restart, I see the "wrong" answer: [FVWM.1][Echo]: unix:0.1 Sometimes a few dozen restarts are required before I see it. With my "regular" (bigger) config file, only one or two restarts are required before the problem occurs. Gregg Dameron -- Visit the official FVWM web page at <URL: http://www.fvwm.org/>.
