I just updated my workstation from RedHat Linux 6.2 to Redhat 7.2.
my dual-head G400 doesn't display output to the second head anymore; even
tho X thinks the display is there. i.e. the second monitor is black.

The X logs seem to indicate that it thinks the display is there; it's
running Xinerama, both MGA modules (one for each head) load, I can scroll
the cursor to that area and it will disappear for a suitably long period of
time before desktops switch in that direction, windows will start and be in
that area (of course, I can't see them).

the old system was running X 4.1.0 and linux kernel 2.2.20; the new one ran
X 4.1.0 until I upgraded it to 4.2.0 (from Redhat's Rawhide source RPMs);
and I've tried kernels 2.4.7 and 2.4.9 (from redhat) and 2.4.19-pre2-ac2
(built from source myself.)

I have tried swapping monitors, to make sure the monitor isn't dead.
I have booted from the old hard drive (RH 6.2), and tried X; and found that
X works just fine, displaying to both monitors.

anyone have any similar experiences? any suggestions what to try next?
