Hmmm.... Looks like DISPLAY, by default, is set to :0 not :0.0 now.
ratpoison doesn't add the screen number if there isn't already one
there.
I am guessing the exact code is screen.c, from line 277:
=== cut ===
/* Build the display string for each screen */
s->display_string = xmalloc (strlen(DisplayString (dpy)) + 21);
sprintf (s->display_string, "DISPLAY=%s", DisplayString (dpy));
if (strrchr (DisplayString (dpy), ':'))
{
char *dot;
dot = strrchr(s->display_string, '.');
if (dot)
sprintf(dot, ".%i", screen_num);
}
PRINT_DEBUG (("%s\n", s->display_string));
=== cut ===
If the "if (dot)" condition fails, it needs to append the string at the
end I think. So something like (not tested):
char * dot;
dot = strrchr(s->display_string, '.');
if (!dot) dot = s->display_string + strlen(s->display_string);
sprintf(dot, ".%i", screen_num);
I think the buffer should already be big enough for this -
strlen(DisplayString (dpy)) + 21 bytes.
