Why? When graphic are sent to a graphics card, a huge bandwidth is used, and in modern architecture it still all goes through the processor. The computers resources are put in to sending information to the card. This slow downs all other processes - and graphical processes have a high priority, as they give us feedback. If this happens on a thin client, the server can go on chugging away and send out other graphics to other clients and its the clients that end up using most of their resources sending stuff to the graphics card, do the colur space conversion and so on. There is an equality of graphics processing amongst the clients. If this happens on the terminal server, the performance of every other machine the server serves is impacted severly. You don't really want your entire organisations computers to slow down because the person on the terminal server is dragging a window about, and this really is what happens. To take on your other points individually: ENERGY SAVING You don't need a monitor on the server, so you are only saving the cost of one thin client, which you can use a very very low wattage machine, and turn it off when you don't need it. The saving would be minimal. SPACE SAVING stick your LTS somewhere out of the way, and maintain it from a client. A MONITOR AND KEYBOARD ATTACHED TO THE TERMINAL SERVER no need, see above SAVING RAM AND HDD There is another way of looking at this. If you use the LTS as a workstation, the RAM and HDD swap will be on the LTS. If you instead us a thin client, which you are making out of an old machine you have lying aroung, then you get EXTRA RAM FOR FREE. There's some LTSP magic for you. GRAPHICAL QUALITY Sometimes true, but you can get hold of very good quality cards very cheaply. This is a very small gain IMHO, when using the server will lower the performance of everyones machine. DVI Same as above, beg or borrow a DVI card, stick it in your client. If you really feal you need a keyboard on your LTS, then use a KVM and swap between client and server. -- From Ben Green All the advantages of Linux Managed Hosting--Without the Cost and Risk!
