Hello, everyone. ...
The Powerpoint displayed perfectly on the large screen for the audience. And when I switched desktops and launched Totem, the audio component of the video clips played through the speakers. But, in the Totem window where the video was supposed to be, I only had a blue screen up on the wall for the audience.

Hi Gil,
I believe that this problem might be related to the fact that most video application use some 'work arounds' to speed up the video output when playing movies. This means that they do not use the standard X server but simply create a window on the desktop an then fill that window by writing more or less directly into the graphic card's memory. That will not work with a dual-head set-up. The only way I can imagine here is to use a standard output method which does not go around the X server but uses it. If you use kaffeine, the
xine
program is used to do the real work. Call xine directly with --help
and it
will display a number of options for the video output methods. Try these and have a look whether any of these will give a display on the second head. Most likely, the output will be pretty slow if it works at all.
Bye, Jürgen
Jurgen, thanks for the reply. I looked at
and found lots of options. But nothing jumps out at me as applying to second head displays. Perhaps I'm not experienced enough to know what I am looking at?
Are you saying that viewing the videos in Xine (with a special option for the video output) might work where neither Totem nor Kaffeine did work? Or am I not understanding?
Maybe a major stumbling block in figuring this out is that I do not have a projector to test possible solutions. I will get my first chance in 2 weeks, when I fly 1500 miles to lecture and only then connect to a projector. Yikes! What a mess.
Gil, my idea behind using xine directly is to make things simpler. As kaffeine is only the graphical front-end for xine, using it directly will remove one step of complexity. If you get it to work with xine directly, you can then edit the setting in kaffeine so that you can use it as the front-end. xine has serveral video drivers (option -V or --video-driver). You should try all of them and see whether you get any picture at all on your notebook and if that works on an external monitor (try to get a monitor which allows similar settings as your projector). For more information about xine's video drivers you can go to http://xinehq.de/index.php/faq#VIDEODRIVER My guess would be that xine -V XShm might provide the best chances but depending on your graphics hardware another of the drivers provided might also work. You could also try to use another graphics driver for your X server if any is available. Sorry, you will have to put some time into trial and error here and the outcome is pretty unsure. This is one of the points where 'that other OS' is much better supported by the hardware producers.
