Badly, I guess :-( But if I did it I would buy: 1 matrox g450 AGP dualhead: http://www.buy.com/retail/product.asp?sku=10401969&SearchEngine=DealTime&SearchTerm=10401969&Type=PE&Category=Comp&Gad=0&dcaid=15891 and 5 matrox g550 PCI dual head: http://www.overstock.com/cgi-bin/d2.cgi?PAGE=PRODUCT&PROD_ID=931103&cid=44344&fp=F# giving me 12 monitors. I now have an epox ep8vtai mobo with 5 PCI slots, so it would all fit. I have 1 GB of memory. May be buy 2 1GB cards instead to get 2GB. Then 4 7-port USB hubs for my 4 usb ports: http://www.newegg.com/Product/Product.asp?Item=N82E16817111971 I plug the keyboards/mice into there. Voilá! Debian Linux 2.6.12 would have no problems with it. A cable Internet hookup I guess. Mobo has an ethernet connection onboard. [OT] from here on! What stops me from doing it: it would be a Debian Linux only shop and I am fearful of the crowd I see in Internet Cafes nowadays and the pervasive M$ advertizing that equates a computer with M$ products.

Well, even M$ users use firefox these days. They are open to different software. Debian has a nice GUI these days, you could choose one of those window managers that are similiar to windows. The biggest difference lies in installation and system maintenance, but your users won't be doing that. :-) I think a debian-based internet cafe would do fine, unless the crowd's chief interest is windows-based games. That's about the only thing you can't do. Internet browsing, including java&flash plugins works. Word processing have several options, openoffice for the masses and latex/lyx for the specially interested. And you can even throw in some linux-based games if you wish. >A case in point: my old alma mater has about 100 PC's >hooked up for its 1300 students.

Plug a hub into your USB, the hub has plenty of plugs for the mice and keyboards. Not enough? Plug another hub into the hub. And powered hubs solves the problem of powering all those devices too. >Wouldn't it be sweet to do a project like that some >place, to find out what the real bottlenecks would be. >Probably the PCI bandwidth like you say... > > Depends on what they do with those screens. They don't eat much bandwith as long as people only is looking. Office/internet cafe activities like mail, web, word processing and lightweight 2D games is 95% idleness for the computer. Scrolling and full-window dragging may be done by the acceleration hardware so it don't put much load on the pci bus. 3D gaming is a different story though. There are motherboards with several pci buses if bandwith becomes a limitation. They cost, but is way cheaper than 22 separate pc's. And only one os image to maintain. :-) Helge Hafting |

I have to disappoint you, unfortunately. SuperTux on my PCI Radeon stalls everything that e.g. tries to access the hdd. However, when I lower the X server's priority, the hdd access gets smooth during SuperTux, but the screen that the game runs on starts developing some interesting effects, like dragging the whole screen back, i.e. in the opposite direction where the scrolling goes and it does it regularly, causing nasty flickering. However, I experimented with Con Colivas' scheduler and it seemed to solve most of this. I expect Ingo Molnar's realtime work will solve this totally. > There are motherboards > with several pci buses if bandwith becomes a limitation.

$2844 for the 22 people Plus the cost of say, a stacked HP Proliant ML150 server class hardware, with 3 year same day onsite hardware warranty, you're still going to spend less than buying 22 even half-way decent workstations What kind of multi-console machine would you buy for $22,000AU (based on a bare-bones workstation =$1000AU x 22 seats) and that's probably a bit conservative.

Display cables have limited length, where image quality goes down if length (and price) grew. I suppose display cables make this mainframe-like build impossible. VGA cable 10meters - $100.

I have a a terminal connected to a keyboard/video/mouse switch, 17 meters of cable far from the computers. PS/2 mouse sometimes loss sync, but everything works fine for me.

You can look it up at: http://www.trendware.com/products/TK-400K.htm . It works fine for me. I have connected it to another small kvm switch in cascade, in order to use all my racked servers and my computer from a single console. The only one problem that I found, is that the magic key to switch between consoles is the same on both switches. I fixed it extending a manual switch key to my local keyboard.

Hi, I've successfully replaced a 2.6.10-ruby kernel with 2.6.13-1.1561 from fedora development using the faketty-0.03 solution-- thanks Aivils! I've got a complex setup....including a PCI Matrox G100 MMS driving three heads (one of which has two screens) and video-out from my old AGP 3dfx Voodoo3 driving my TV for mythtv output (as soon as I get the bt869 i2c driver working with 2.6.13, doh). Input comes from one AT keyboard, two USB keyboards, three usb mice and a ps/2 -> usb converter for my pc /tv airlink keyboard / mouse (useful from the TV with mythtv). Just updated to FC4. In working with it last night, I moved my usb printer (cannon i550) from one usb hub to another, and suddenly, the usb mouse on one of my heads stopped working. Took a look at /proc/bus/input/devices, and it looked like the faketty ordering changed, with the ftty2 entry normally associated with that usb mouse missing. Haven't tried reproducing the problem yet, so maybe it just a fluke, but after a reboot this morning, did notice that it was fine. Frederick Koehler Aivils Stoss wrote: >On Sestdiena, 17.
