• Xorg problems on dual boot machine

    I have an HP dual-boot machine running both FreeBSD 10.0
    and Solaris 11.1. These systems have the following Xorg
    server and Intel drivers:

    X.Org X Server Intel driver
    FreeBSD 10.0 1.7.7 2.7.1
    Solaris 11.1 1.12.2 2.18.0

    In short, xorg runs under FreeBSD driving the monitor at
    the preferred mode, while it fails to start under Solaris.

    The monitor is an HP L1910, its preferred mode being
    1280x1024 @ 60 Hz. Even though the log file shows that this
    mode is being selected (well, a mode called '1280x1024')
    the monitor complains about the 'signal being out of range'.

    Xorg under Solaris appears to pick up the monitor's
    preferred timings, i.e, after 'First detailed timing is
    preferred mode' it details the monitor's (manufacturer's)
    'Supported standard timings' and then 'Supported detailed
    timings' which are what FreeBSD xorg is using, which in
    Modeline format would be:

    Modeline "1280x1024"x0.0 108.00 1280 1328 1440 1688 ...
    ... 1024 1025 1028 1066 +hsync +vsync (64.0 kHz eP)

    The machine (HP dc7900) has the complication of having an
    HDMI slot which is not in use but this seems to be ignored
    by both the FreeBSD xorg and Solaris' xorg and the latter
    picks up some other kind of output called 'DP1', which is
    absent from log file on FreeBSD and which 'xrandr' on FreeBSD
    doesn't report; but again, this seems to be ignored
    ('disconnected') by the Solaris xorg.

    I would be grateful if someone could give me some hints as
    to what's going on here.
