@Andruk: "I'm a complete newbie to X, so take everything I say with a grain of salt, but I doubt that you'll be able to do this without purchasing some good (read: expensive) hardware and doing some _heavy_ hacking on X and some heavy hard hacking. My understanding of video signals tells me that this probably won't work. I would hazard a guess and simply say that your usage case is at least close to impossible, if not completely impossible." A: Im no expert either (far from that, actually), but I think the good/expensive hardware wont be necessary.. I mean, if I choose to have like 10 virtual desktops and hold down Ctrl+Alt+Right Arrow Key, the VD's change so fast until the last one that I can barely notice anything... And thats on a low configuration machine. About the heavy hacking on X, yes, thats more likely.. I have no clue if I'll be able to do it, since, as Ive said, Im no expert on this, but.. Lets see how far can I go :P "I've implemented a pong-like animation using just hardware on a Xilinx FPGA over the VGA port, but I don't think you'll be able to find an FPGA with >2 VGA outputs. This means that you may be forced to design and implement your own circuit from scratch, which is not a trivial task." A: Forgot to mention on my huge explanation.. The external circuit won't be build by me, but by my boss, who's graduated (PhD maybe, not sure) in electronics (or something like that). He wants me to be able to switch desktops and send the synchronized signals through the parallel port (which is no easy task anyway ._.). "Heck, best of luck to you if you decide to try to implement it anyway, though. Be sure to post pics and a rough guide of what you did and how to do it if the project becomes unique enough to warrant it." A: Thanks, be sure I'll post all about it if I manage to do such thing :P ------ @Tim Nelson: "This may not be helpful at the moment, but should you decide that you need to go down the multiple displays route eventually, there exist screen cards that do 4 VGA ports on the one card. Unfortunately the only one I know of requires PCI Express, but I'm fairly sure there are others." A: Yeah, I hadnt heard of the existance of 4 headed graphic boards, until like half an hour ago, when someone mentioned you could find 4 headed PCI graphic boards easily on eBay (cant really remember who it was, sorry :S so many messages coming at once...). Ive already wrote down this 4 headed graphic cards alternative as my last try, when there are no more options available, thanks for the tip! :D
