Have you tried ARandR? I always use it when I have two monitors...

Hi there.
I'm trying to configure my monitors on my Xubuntu 18.04.3 (64-bit)
installation.
I have two 4k monitors and a 2k monitor that I'm trying to use to
display an extremely wide (9600x2160) desktop.
However, when I enter the display settings and configure the monitors
horizontally, the right side of the rightmost monitor goes blank.
The tip of the mouse pointer won't go into the blank area (as the edge
of the blank area seems to be the edge of the desktop), but if the tip
is at the far right of the desktop, the rest of the pointer is visible
in the blank area.
Some tinkering suggests that anything to the right of 7680 horizontal
pixels is blanked out.
If I rearrange the displays such that one is above the others (and,
therefore, the full desktop is no more than 7680 pixels wide), all
three monitors work perfectly. But that's not the configuration I want.
A bunch of googling didn't give me any ideas.
Is there a maximum-desktop-width limit somewhere in the stack that I'm
brushing up against, or is there some weird problem with my specific
setup?
Thanks,
Steve McClellan
