KDE 4 "funnies" in 11.1

I’ve been running KDE 4.0 with SUSE 11.0 on my laptop and I
had been running KDE 3.5 with SUSE 10.3 on my desktop until
my system disk crashed last week. I have since replaced the disk and installed 11.1 with KDE 4.0 on my desktop system.
There seem to be a number of differences (oddities) between
KDE 4.0/SUSE 11.1 and the previous combinations I’ve run:

  1. When I plug a USB disk into a port now, the “recently plugged”
    devices window comes up. But if I don’t EXPLICITLY click on
    the object in that window and open a dolphin window the disk is not mounted. Since I don’t really want to use the GUI window
    this is a **** annoying way to have to mount the disk. I note
    that with KDE 4.0 and SUSE 11.0 on my laptop the disk is
    always automatically mounted. Is this a difference between
    11.0 and 11.1? Can I change the way it’s behaving in 11.1?

  2. I sometimes want to use a different windowing system
    (specifically FVWM). In previous versions (including on my
    laptop), I had the option of changing windowing
    systems between logins. That seems to be gone now? I see
    that if I go to Configure Desktop → Default Applications →
    Window Manager, I can make a change but the only two that
    seem to be available are “Compiz” and “GNOME”. If this
    procedure will actually switch windowing managers then
    how do I add FVWM to the choices and most importantly, how
    can I switch BACK to KDE once I’ve gone over to a different
    windowing system if I no longer have a choice at login?

  3. I’m running two monitors (in Xinerama) on my desktop
    system. KDE seems to be unaware of the second monitor. I can
    drag windows into the second monitor, but KDE doesn’t
    automatically put a background there, and if I drag a window
    around on that monitor, the window “wipes” the default black
    “background” and leaves a white “trail”. This did not happen
    with KDE 3.5/SUSE 10.3 before my disk died.

Well, scratch number 3 from the list. I found a fix
on my own.
