Package: xserver-xorg-video-ati
Version: 1:6.6.2-2
Severity: important


Back when X.Org was introduced to unstable, there was a bug where when X
was started up, the DVI flat panel (Apple Cinema Display 20") went into
standby mode, and wouldn't come out.  This could be worked around with
IIRC a PanelSize option and a few other manual tweaks.  This was later
fixed, and the special options were no longer necessary.

With the latest version, this bug has reappeared, and the monitor again
goes into standby when the X server starts.

The relevant parts of xorg.conf follow.  If I uncomment "UseFBDev", the
monitor won't come out of standby even if I kill the X server.  The
other commented out options don't appear to have any effect.

I'll be happy to do any further testing.
