Re: [XFree86] dual-head - dual-user question
How about using Backstreet Ruby? http://varna.demon.co.uk/~svetlio/ruby-contrib/how-to/ XFree_local_multi-user-HOWTO/about_bruby.html It allows the use of multiple graphic cards, keyboards etc and I guess would allow what you are looking for. rgds anders On Friday, October 3, 2003, at 08:03 AM, Mark Knecht wrote: Jay, Thanks.

Re: [XFree86] dual-head - dual-user question
Can XFree86, with any known graphics hardware configuration, handle two separate users running two separate XFree desktops on the same PC? These two users would log in separately, but share machine resources. ssh is not an option. Yes. You should use unofficial patches. The best solution, in my mind, would be if a single dual-head graphics adapter could be used such that one user is on one monitor and the other user is on a second monitor. Will not work in my end! Less compelling, but still acceptable in my specific case, would be a second graphics adapter, PCI-based, that displayed the second desktop. Dual-user works for me since APR-2002 and triple user since SEP-2002. This mean 1 AGP and 2 PCI video adapters. Also 2 PS/2 keyboards, 1 USB keyboard, 2 serial mice, 1 USB mice. This system runs with Nvidia video adapters only and Nvidia closed source drivers. This one allow run two GLX applications (like Quake3) run simultaneous. Linux already can serve multiple sound cards. So I use 3 sound cards. Each user has X server, sound device. Each user has video adapter, keyboard, mouse, sound card. http://startx.times.lv/ http://www.tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/ Advantages: Cheap full independ second (triple) head. CPU power utilization. Disadvantages: Unfortunately applying the kernel patch and system set up is not easy task. GLX performace is not wery good if 3 instances of Quake3 run simultaneous. User's workplace must be placed near each, because cables are short. Some video adapters are enemy by default and will not run simultaneous. Is anything like this possible? Can the two monitors be considered as two completely separate displays by XFree? Yep. I have success report about system with 4 concurent X servers (Inet cafe or similar). If it matters, I had intended to run Gentoo Linux if I can. You can use any distro. Aivils Stoss ___ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86

(Unless possibly User 1 == User 2) Since they're both on the console, yes, you'd be able to switch between them: remember, they're on the same monitor. If, in fact, they're *not* on the same monitor, then I don't know *how* the console driver (which is in *front* of all of this stuff) handles that.

I'm not sure how well that will work; you'd have to *keep* Linux from seeing the one on the USB port -- you *only* want X(2) to see it, and I'm not sure you can.

My point was merely that it may be cost-ineffective to go through all this work, unless you can find someone else who's already done it, and can cookbook it for you. But I guess that's what you're doing, isn't it? Any special reason why they need to share the machine? Computers are *CHEAP*. You can't cost-justify the *labor* to figure this out before you've paid for a new box... Cheers, -- jra -- Jay R.
