Second monitor doesn't quite work
Last week I replaced my video card. The old one, made by Zotac,
contains the Nvidia GT630 chip set. It has two DVI outputs, which I
used to feed two monitors: a BenQ GL2760 and my trusty old Sharp
LL-T19D1-B. The new card (ASUS with the GT730 chip set) has only one
DVI output, but also has HDMI; I switched the BenQ monitor over to its
HDMI input.
I used the Nvidia X Server Settings utility to set up the displays; it
detected both monitors. I set it up to use the larger BenQ monitor as
the primary display, but when I boot the system the POST and boot
messages come up on the Sharp monitor. Once the boot is complete, the
desktop appears on the BenQ monitor. The Sharp is black; I can move the
mouse pointer over it but no windows will open on it. If I try to drag
an existing window from the BenQ to the Sharp, it flips into an
alternate desktop. Interestingly, xscreensaver finds both monitors and
displays on both. However, xrandr can only find the BenQ monitor
(HDMI-0); the Sharp monitor (DVI-D-0) doesn't show up.
I tried swapping the monitors, but that just caused everything from boot
to desktop to appear on the Sharp monitor; the BenQ stayed black (except
for the mouse pointer and xscreensaver output).
I'm running Bullseye. Originally I was using versio 390.xx of the
Nvidia driver, but upgrading to 470.161.03 had no effect.
Any idea why the second monitor is sort of there but not quite? Below
is a copy of the xorg.conf generated by the Nvidia setup utility.
