Hi,

First of all, I post in the newbie forum because I am a total newbie... I began with Linux (Ubuntu 9.10 "Karmic Koala") 4 hours ago. So if you answer this, please use simple words, and don't hesitate to be very descriptive

I installed the display drivers for my graphic card (nvidia 9600 GT), and configured the xconf thing and the Xserver to allow multiple displays, and it works fine. I have a computer screen on my table, and a television 3 meters away in front of my sofa, connected to the PC.

I used the "X screen separate displays" method, and I really like it, because, unlike on windows, I can totally handle my computer from my sofa OR from my desk.

But I have a problem : If I am at my desk and open firefox, then go to the sofa and try to open a firefox windows, it says "firefox is in use and does not respond, you must close... blablabla". and as it is X Screen, I can't drag a window from a display to another... so I am actually obliged to get up, close every open window on my "desk" screen and go back to the sofa.

Is there any solution to this (for example, a way to open a new window of Firefox without running the application ?

Well, this is not a huge problem, and I must admit that Linux progressed A LOT... I tried to go to Linux 5 or 6 years ago and it was so horrible that I gave up after trying to copy a file from the floppy to the HDD for 3 hours... but now, everything is really intuitive and in 4 or 5 hours, I have a working OS, internet connexion and multiple displays... GREAT !

Firefox's default starting procedure is to look for a running instance and connect to that if it finds one. You can only have one instance of a given profile running at a time.

From a console window, run "firefox -ProfileManager", where you can create new profiles. Then you can run that profile with "firefox -P profilename". You can then add this flag or "firefox -no-remote" to the command in whatever shortcut(s) you use to launch the program.

"man firefox" will show you all the available options.

PS: It's possible to create a simple startup script that will kill the currently running instance before re-running it, but it wouldn't be a clean shutdown.

So, when I try to open Firefox on the second display, why doesn't he find the first instance (running on the second display) and connect to it ?

Thanks for this answer (even if I didn't really understand the second part of it
