Please bottom post on this list - thanks :-)

Then it sounds as if you may need to create an xorg.conf for that
particular monitor with the proper Horizsync and Vertrefresh options for
that monitor. Example:

Section "Monitor"
	Identifier	"Monitor0"
	Vendorname	"Dell"
	Modelname	"Dell E172FP"
	Horizsync	31.0-80.0
	Vertrefresh	56.0-76.0

Problem is that without an exact specific model I can't tell you what
they are. For example, I just finished with a customer using the above
monitor & I was able to determine the freq's from:
http://support.dell.com/support/edocs/monitors/e172fp/En/specs.htm
But searching for generic 'Philips 150S' on the Philips site I find many
different models. Only other thing I can suggest is having a look at:

<http://www.google.com/search?hl=en&complete=0&q=ubuntu+%2B"Philips+150S"&btnG=Search>
and see if you can find a solution. Maybe the settings shown in:
http://ubuntuforums.org/showthread.php?t=131868
will work.

That said, you should at least get _something_, when you start up (you
have tried rebooting?) Your problem is looking more like a video driver
issue as 9.10 should at least try to bring up the monitor even if it
doesn't know what it is. If all else fails, you can try putting this
into /etc/X11/xorg.conf and reboot:

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"vesa"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
EndSection

It will also help to know what type of system (hardware) & graphic card.
And just what happened and/or what you've done other than simply connect
a different monitor to the system. Also, what was the 'widescreen
monitor' that malfunctioned & details around that event.
