My major gripe with GNOME is its incredible slowness as soon as you
enable any kind of pretty theming, in either Gtk or Enlightenment. Am
I missing something? I haven't seen anyone else complain, but I've
tried it on two fairly high-end machines, and glacial is about the best
way I can describe it.
The other thing I dislike about the default Red Hat (5.9) distribution
is the fact that E is not as nicely integrated as one might like - E
places a row of icons over the panel, in the bottom right of the
screen. That's a pretty minor cosmetic issue, to be fair, but first
impressions count, and that's not a good first impression.
Sort the speed out, and GNOME will be extremely nice. Until then, I
just can't use it.

It might be hardware related. A friend of mine had an Abit BX6 Pentium
II board that had a broken PCI slot. If there was a card in that slot,
using it sometimes caused spontaneous reboots. You could try using
another motherboard to see if possibly the AGP slot is faulty.

Subject: Help with GCC!
Hello all! Im having a problem with GCC... A while ago, for some
stupid reason, I upgraded my GCC to 2.8.1.. hehe Well, I
recently got the 2.0.36 kernel source, and tried to compile it and I got
an error saying "Blah blah.." and that I needed to have
GCC 2.7.2.1 (or anything within the 2.7.x.x range, I think).
So, I went and downloaded Gcc 2.7.2.1 and installed it via RPM--no
problems there, "gcc -v" reports version 2.7.2.1. Thats
all nice and dandy, but I go to compile the kernel and what do I get? A
missing .o file! =( I couldnt find it on my machine at all, so
apparently RPM deleted it while it was.. well.. downgrading. I used
"rpm -Uhv --force blah.rpm". Maybe that had
something to do with it..
BTW--the file name that was missing was crtbegin.o.
My question: Where and what package does that file (and its
dependencies) reside? Preferrably in rpm format.
Thanks alot! and please reply via e-mail to: [EMAIL PROTECTED]

I never looked at it but this seems right.
The following mail might be interesting for anyone interesting in
doing DMA to user space; it does not explicitly talk about DMA but I
don't think that makes any difference.

You cannot.
This keeps coming up, and even sane people like Alan Cox want to do it,
even though it is fairly obvious that it should not be done that way.

No. That doesn't help in the least.
By the time your interrupt handler is called, the process is long long
gone and even if it was the current process it might have changed its
mapping.
Basically you should never EVER even consider writing to user space from
interrupts. EVER!
Basically, you should always use a kernel-space buffer. Just accept that
as a fundamental notion, and your life suddenly turns a lot easier.
Now, I know about zero-copy. I'm not a big believer in it, but I certainly
know about it. And having a kernel buffer does not imply that you can't do
zero-copy. It just means that you can' tdo the initial copy to user space.
Sounds contradictory? Think "mmap()". It works, it's there, and magically
all the problems go away. Don't make the mountain go to Mohammed. Instead,
think of your problem the other way around: instead of the kernel writing
to user space, think of it as user space asking to see a window of a
kernel buffer. You make a device driver that has a mmap() function, and
suddenly the device driver can write to kernel memory, and whatever it
writes magically shows up in user space too.

There is an application being made which is called 'dia' and is
supposed to be an open source replacement for VISIO. At this moment
it is still alpha, but it looks *very* promising.
Have a look at: http://www.lysator.liu.se/~alla/dia

Then edit /etc/lilo.conf to boot the new kernel image and then run
/sbin/lilo. It's usually a good idea to just add an entry to
/etc/lilo.conf rather than replace the existing one...that way you can
still boot to your old kernel if something goes wrong.
Hope this helps.

Something about glibc-2.1 not being able to be compiled with the Official
GNU C compiler (i.e. gcc), but that it needed to be built with egcs. Now
that egcs is going to be the official GNUC C compiler I would expect this
to be resolved relatively soon.

Subject: Extending LILO - booting over serial port?
Date: Wed, 28 Apr 1999 16:37:43 GMT
Hi!
I want to do some experiments with OS development and I am in the
lucky situation of having two computers. So I suppose floppy
swapping would do.
But since there is this nice nullmodem-cable between the two
computers I wondered wether it is somehow possible to load a kernel
image file over a serial port.
If it has been done, it would be striking. If it has not been done,
I'd volounteer to implement it.
But I'd need information about LILO - it seems (to me) that the code
is not too-well documented - so perhaps somebody got a clue how to
implement this best?
I see two possible ways:
- writing a loader, then creating a 'dummy' entry in lilo.conf
(meaning: other=3D/dev/zero; unsafe; loader=3D/boot/serial.b) - is not
very elegant, but wth...
- modifying the second stage loader and extending tha map installer
with a "serialboot=3Dimage" or "serialboot=3DbzImage" option for
lilo.conf. Besides of being elegant, this would have the advantage,
that I would probably only have to replace the disk reading parts of
the second stage loader.
I will probably try to implement the first variant - could somebody
tell me, in what environment the loader is loaded? Which registers
are set up etc.?

And with the above bug fixed, the range goes down to 12180 -> 23551,
so 16384 would actually not work right (lucky I stayed at 8192).

It is gnome-core-1.0.4-34, but I have a feeling that the problem may be with
enlightenment. (enlightenment-0.15.5-32) If I am running netscape
communicator with the Mail and newsgroups window and a browser window, and
lets say that the browser is on top, if I click on the little lower right
