What is needed to run X gracefully under Interactive? Can someone
please throw some light/wisdom on possible incompatibilities and/or
known bugs/limitations with the components I have. Please email
your comments; I will summarize and post them later.
On an ALR 33/486 we are running Interactive 386/ix 2.0.2, along with
their X Windows 1.1 distribution ... and the performance sucks.
We have a Microsoft serial mouse and a high-performance Microfield
V8 graphics card on the system, ... but, the mouse drags are at a
lag of 3-4 seconds behind!
I would like to know what is the best known combination of components
if I were to go for a price independent choice of graphics card,
machine etc., preferably with Interactive o.s

You've got Real Nice Hardware, and interactive is really able to use it! we used a 386/25 with a microfield and a genius mouse with very good results. keep trying! -- Heiko Blume <-+-> src@scuzzy.in-berlin.de <-+-> (+49 30) 691 88 93 public source archive [HST V.42bis]: scuzzy Any ACU,f 38400 6919520 gin:--gin: nuucp sword: nuucp uucp scuzzy!/src/README /your/home

Something is horribly wrong with your system. I run 386/ix 2.0.2 with
Interactive's X11 1.1 on a 20 MHz 386 and the performance is pretty good --
actually very good, except for loading big bitmaps. At work I have a 25 MHz
386 running SCO Open Doorstop; it's quite a bit slower, but nothing like
what you've described.
I have noticed that my work system, which has a Logitech serial mouse,
exhibits very slow (although not measured in seconds!) and erratic mouse
response. At home, I have a Logitech bus mouse, and it works MUCH more
nicely. So I would recommend ditching the serial mouse, but I suspect
there's something much more fundamental wrong with your system.

Some clients animate mouse drags badly. When mouse motions can be generated faster than the thing being animated can be drawn, the naive code produces animation which lags the mouse, and lags the mouse more and more as the mouse is moved. (If the mouse is left still, the animation eventually catches up.) This problem will often go unnoticed, because when everything is running on nice fast machines with a nice fast network between them, the time to update the animation is tiny compared to the interval between mouse events, for any common animation (eg, window outlines). But throw in a couple of slow gateways, or a machine which draws relatively slowly for some reason, or a hardware/server combination which produces mouse events unusually quickly, and you have a recipe for bad lags when mouse dragging. This problem arises when clients stupidly update the animation on receipt of each MotionNotify event, without paying any attention to all the other MotionNotify events that are sitting in the queue. This is precisely what PointerMotionHintMask was created for; everybody doing this sort of mouse dragging should learn how to use it. (Some clients "fix" the problem by doing a stream of QueryPointer requests instead. This sort-of cures the problem when it's due to slow drawing or fine-grained mouse tracking, but actually makes netowrk-caused problems worse. It's not the right fix.) der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu

Just a whim, but check to see what interrupt you are using for the mouse. I tried my tape drive on interrupt 2, and it did not work. I changed it to 9, and it works fine. The sympthoms were similar--it sort of worked, but real slow. A net neighbor had a similar problem with his mouse. -john- -- =============================================================================== John A.

This isn't the case with any of the Logitech serial devices we have here. They all work like a charm and the response is great. (we use both serial mice and serial trackballs). If you are having problems with a mouse, it isn't the class of mouse itself (in other words, your mouse may be screwed up, but replacing it with another one from the same manufacturer should fix the problem). -- Conor P.

I've got a serial Logitech-mouse here, and had some trouble with it, especially when starting the server (it would fail every other time) until I changed the configuration from LOGI-S to MSC-S and since then it's been working just fine. I think I saw this fix in the Release notes somewhere. Heimir Thor Sverrisson (TF3ANT) heimir@hafro.is
