This is only a partial answer, but will help start things on the way.
If you set your virtual resolution, via either a configuration utility or editing
/etc/XF86Config,
to match your desktop size, then you have the essential part of making your desktop
the same size as
your screen.
If you set the resolution to higher modes, e.g., going from 640x480 to 800x600, it'll
place the same
number of dots on the screen, but place them more compactly...it'll appear to shrink.
You may have settings for these for each color depth, so you might want to change this
in more than
one place to see the results everywhere.
Note that any mode that is not within your listed scan rate ability for your monitor
will be
rejected summarily. So if modes are there that should do the job, but they are
rejected, likely they
call for something the server thinks is outside your monitor or video card specs.
You can also edit your modelines to do some fine tuning. You can get new modelines by
viewing the
results from xvidtune, and noting what it tells you for a particular mode. Then
comment out your old
mode lines for that scan size/rate, and enter those instead (again, /etc/XF86Config).

Date: Thu, 08 Apr 1999 22:11:32 GMT
Unfortunately, /proc/devices shows:
Block devices:
2 fd
even if the floppy drive physically is not there. So this test does not
work. I have a machine here with no floppy, and this shows up.
The output from the "dmesg" command also shows the floppy even if it is not
physically there. Apparently the floppy driver doesn't actually care if the
physical drive is really there or not. So modprobe may well give a false
indication that the floppy is present when it is not because the driver may
well load even though the floppy drive isn't there. I'll go ahead and try
making the floppy be a module anyway and try it just in case. A quick look
at drivers/block/floppy.c doesn't look very promising.
Interestingly, on a machine with an empty floppy drive, attempting to read
gets a quick error. This is fully satisfactory. If I could get the same
thing to happen with the drive not there, that would be the solution.
I may have to find a way to literally do some sort of I/O machine instruction
to probe the status of the floppy base address to see if it is there. Even
then I don't know if I'm waiting for some interrupt that won't come back.
Alternatives?
The purpose of this is to have a cheap place to store a small set of config
data for a system that is booting up from a CD into ramdisk, with the CD
mounted as /usr, and some things in / being symlinks to a subdirectory on
the CD. What I plan to do with the data on the floppy is to untar it into
a /tmp subdirectory, pick certain files from it to replace corresponding
ones in appropriate places, and then remove the /tmp subdirectory. This
will be happening before /sbin/init runs (so I can even get /etc/inittab
from the floppy).
I am considering flash disks. But a cheap removeable media would be highly
preferred. Are there any removeable flash devices that work with Linux as
an ordinary device (e.g. emulates a floppy or IDE drive)?

Looking at the different possibilities to achieve the task, I think the way that best suits my needs is the patch from Robert Kaiser, since it is the only one that allows to supply a standard read()/write() interface for the user, without requiring him to work with specially allocated buffers or anything like that. There are already quite a few applications requiring data transfer rates high enough for not wanting them to be copied around in memory only for operation system handling reasons, and their number will definitely increase in the future. Just think about things like FireWire or ADSL. Therefore, I am somewhat astonished that Linux obviously lacks the capability to support such a thing unmodified! This is something lots of OS's like AIX, SOLARIS, Lynx etc do support. Even Windows NT can do it and does not even require much additional effort for the driver writer. Is there any chance that Roberts patch (or any other code that achieves the same thing) will make its way into a future kernel version? IMHO, it would *really* improve Linux.

Can your BIOS actually read the device for booting purposes? It may or may not really be a "plain vanilla" IDE device. PCMCIA cards tend to use special commands with special drivers, and booting from there may not even be possible. -- Phil Howard KA9WGN [EMAIL PROTECTED] [EMAIL PROTECTED] -- From: Eugen Dueck [EMAIL PROTECTED] Subject: Re: Newbie Date: Fri, 09 Apr 1999 11:12:37 +0200 comp.os.linux.DEVELOPMENT.system Craig Christensen wrote: I resized my resolution in XWindows and after rebooting it is gigantic and I can't read anything.

I don't have a Solaris 2.7 here, but I doubt if it is any different. It depends what you mean by "STREAMS TCP/IP" :-). Most of the SVR3 derived systems used the Lachman stack which used a BSD-ish IP module with STREAMS wrappers front and back. The socket interface was dumped behind a STREAMS message interface and accessed by simply setting up the socket call number and arguments in a buffer instead of on the stack and passing it down through the STREAMS head using an ioctl. Back when Wyse were in the large(ish) systems market (around a decade ago) they mapped all the internal socket stuff back in to the system call table and their socket library bypassed the STREAMS layer. SCO introduced the system call bypass in, I think, the net100 patch to 3.2v5.0.0. Even with today's network speeds the overheads in dereferencing through STREAMS module stacks and the cache pollution implications become significant - especially once you start talking about fast pathing IP.

Subject: Stupid shell question:
Date: Fri, 09 Apr 1999 14:12:53 -0400
Ok, I feel like an idiot for asking but my shell experience is still
somewhat limited and I haven't had much time in the shell recently, so I
thought I'd ask:
How do I phrase a command such that the command is actually spawned into
another shell, creating an entirely new window in an XWindows session?
For some reason it seemed like it was simple like ending with a '' but
there must be more to it. I'm using the BASH shell.
Also, along these same lines, I use the Cygnus GNU compatibility toolkit
under my Windows toolkit. Using the BASH that came with it, is this
something that is even possible? I've written a little batch file that
launches cmd -c under NT and will run "start" to pass it the parameters
so as to have this effect. It just seems like there would be a better
way to do this the same as under Unix. I will be putting Linux back on
my home box soon and I wanted to remember how to do this since I tend to
use shells, makes and VI as my development environment.
Thanks!

Hi,
I profile my programs (prof or gprof )
And before now i have no problem.
Now,
I've wrote a dynamic library ( .so ) that I link at the complilation
step to my main
program.
gcc myprog -o a.out -lmylib
BUT : gprof see symbols only in the main program ( a.out )
and give no statistics about the functions of the library.
Do anybody know the option ( of gprof or gcc ) for watch the symbols
of a liked library
Thanks .

Who hasn't accepted which "fundamentals of process improvement"? The difference in motivations and payoffs and intended user community should be pretty clear. Nope, not at all. How would having a decent IDE hurt?? It probably wouldn't hurt but I don't believe it's a necessity either. The phenomenon of masses of volunteers creating novice-friendly applications for Linux due to altruistic motives or a desire to see a free software platform succeed is a relatively recent phenomenon, and the efforts of these intentions haven't been fully realized yet. Probably because the tools suck! Well, that's your opinion. I'd guess that most of the people using them wouldn't classify them as "suck". Another issue with Unix software is that graphical apps make demands on the availability of X Windows running and on bandwidth of a network connection that prohibit work in many situations, so people typically refrain from doing something that only pays off in eye candy rather than functionality if it is going to be useful in fewer circumstances. Yeah right, like people develop over a LAN or WAN. Give me a break. Your child-like resistance is noted in your use of "eye candy" and dropped your case to ground zero. Well, around here, that's how we do our developement. For instance, I typically have xterms open to 5 other machines for developement and testing. My editor (Xemacs) runs on my local workstation and I do compiles or testing on the other five machines. I never compile on the machine that I edit on. Developing over a LAN may not be common with WinDoze programmers, but it is not unusual for Unix developers. There is one part of the quoted text above that does hit near the truth, I think - the libraries for creating GUI apps on Unix were traditionally too hard to use. For example, I recently worked at a software company where the main development environment was HP-UX, and I found myself far and away preferring the character based version of their debugger to the graphical one, even when I was sitting at an X station, because the character based one offered more functionality. It was obvious that so much effort had gone into the initial production of the Motif GUI for the visual one that access to functionality and bug fixes had gotten left on, even though the underlying internals of the debuggers were identical. This library situation is changing rapidly. Agreed, X sucks. No, he said Motif sucks. Big difference! This is partly historical accident (generalizing from the transition of MS-Dos to MS-Windows), partly socialization (Windows users are trained to be application oriented rather than tool and data format oriented and trained to learn by trial and error rather than by reading documentation), That's not a particular correct way to state it. The fundamental principle is that people can relate to pushing buttons and such just like most can use a stereo system. And most people can't operate their VCR for anything other than straight playback either. Single examples don't prove much of anything. I think the defensive posture taken by your kind is probably because you just don't have a GUI that is useful or elegant (X sucks) so you have to patronize yourselves. Right? Can you name this "useful or elegant" GUI? (Opening myself up to the Mac fanatics!) It sure
