i have the same problem. multi monitors in linux has always been a
reason i never went 100% linux in the house. i have the exact same issue
described here. the external monitor drives a projector and that won't
show the video, just black in that box. i have not tried a screen
capture. i tried to reinstall and reconfigure xserver-xorg-video-ati as
above but that did not help, possibly because i am not in 24 bit color
mode but i don't know how to change that. one thread i tried indicated
editing the xorg.conf file but that had no section in it for color
depth. why isn't color depth just part of the screen resolution tool as
one would expect?

speaking of the screen resolution tool: if i uncheck "clone displays" or
whatever, it still only shows the one display. "detect" does nothing
either, but when i try to change the resolution after unchecking clone,
then suddenly it shows the other display as "unknown". i can change the
resolution of that seperately and that actually widens my projector
display (though it doesn't stretch the taskbar to fit). now i am from
the windowsXP familiarity so i expect a button to "make primary", so
that you could at least watch video on the external but not the
internal.

another question i have related to this is why does my Fn key to switch
between int/ext/both do NOTHING? in windows you have to be set to "both"
before it even sees the displays seperately, else if set to int it
clones to the ext. what i want to do in ubuntu is just set it to EXT
only because i have a hunch that would be a workaround to this bug but i
can't even do that because of what appears to be another bug related to
Fn keys. i tried using that xev tool to see if i just have a x keyboard
congfig issue, but pressing Fn or Fn+ext display key does not indicate
any activity is happening at all.

AND, at no point after the booting-up screen is the S-video output
detected or displaying anything. on boot up it shows a clone of the main
screen, after that it is disabled and i can't find any info on
activating this. i windows you used an ATI tool to switch between no
more than TWO of: INT, EXT, S-Video in various combinations of cloning
and multi-displays.

anyway, this is the ONLY thing i do with this laptop: display movies to
a projector from a network with the occassional browse of the net, so it
seems like a real shame that i have to run windows to accomplish
something that Macs could do 16 years ago.

can someone resume this thread and help us start working through these
issues until they are resolved? i would be happy to post any debug info
or config info to help. i am running a compaq evo N610c, but i have seen
that Fn keys and external/multi monitor issues are a common problem on
many laptops.
