Slightly off topic, but:
No need to avoid Optimus. Just make sure it can be disabled from the
BIOS. I just purchased a Dell M4600 Precision laptop with i7 processors
and an Nvidia card.
F15 runs nearly perfectly (including Suspend to Ram), after a few system
tweeks. But the first thing I did was disable Optimus (and the 2nd was
to add "reboot=pci" to the end of the kernel boot parms in grub.conf to
fix a problem with warm rebooting.

Very frustrated with F16
by Paolo Galtieri
I just installed F16 as a VM under VMware. After booting up and installing
all the updates I cannot find the 2 system config settings that are present
in F14.
Specifically the Windows and Startup Applications config items. The first
allows me to configure windows so that they become active as soon as the
mouse enters them. The second allows me to setup my configuration so that
all applications that were running at the time I log out are automatically
started the next time I login. Where are these configuration items? The
Windows one used to be part of the control-panel package, but it's no
longer there.
Note I am not running gnome-shell since it failed to start so I'm running
in fall back mode.

Fedora 15 x64 stunning performance (vs Win7).
by Quicksort
Hardware platform: Dell Studio XPS, Core i7 950, 8Mb L3 Cache.
Operating systems: Fedora 15 x64 / Windows 7 x64 Ultimate
Hi everybody,
I have developed a sorting/searching library written in assembly
language. As long as one stays in the L1 Cache (in place physical sorts)
speeds are identical, but when the proportion of L1 cache misses
is hign (sorts by reference which return an ordering vector as APL
sorts do) Fedora dramatically outperforms Win7.
This performance gap is stunning but consistent and I am not overdoing
it. Something weird occurs when one leaves the L1 cache. As one remains
in the L3 cache (my Core i7 950 has a 8Mb cache) the performance penalty
is about 33%, with mixed L3 cache/main memory accesses it grows to
50%/60% ! I wish some x64 Linux kernel developer could enlighten me. The
assembly code is exactly the same in both cases(except or course for
calls to APIs being replaced with Linux system calls), JWASM assembler
being used. No disk swapping, large/huge pages, or virtual machine
involved and my test program is a plain application run from the command
line.
Any thoughts?

Might want to check this out.
http://www.nvidia.com/object/product-geforce-gt-555m-us.html
GeForce GT 555M
Outstanding DX11 graphics performance and long battery life with NVIDIA®
Optimus™ technology.
Try booting a rescue disk to check hardware out(lspci).
Again check your bios to see if you can disable Optimus.
There are some efforts out there to make this work with Linux.
I think bumblebee might be getting close to working or is.

What video card are you using with the i5 server.
Not sure if this is your issue but I just did a lot of research before
buying a new 17" laptop and avoided systems with Nvidia video that had
the Optimus technology. Seems there is a lot of grief with running Linux
with those cards.
We have some systems at work with Ubuntu but, they have a mux switch to
turn off Optimus in the bios. Couldn't find out if the XPS17 had this
option.

Where is it with f16/G3?
I once saw that poor excuse of a popup at the bottom of the screen

F16-X86_64-Live-KDE won't boot on XPS 17
by linux guy
I have a new Dell XPS17 laptop. (i7, 16 GB RAM, nvidia 555 video
device, Windows 7 installed)
I am trying to run F16-x86_64-Live-KDE on it via a USB flash device.
It find the USB device. grub(2) runs. I can select the kernel. It
starts the boot process.
It hangs with the following message:
udevd[166]: /sbin/modprobe -bv pci: <snip> [168] terminated by signal 9 (Killed)
dracut: starting plymouth daemon
The same OS on the same USB flash device runs fine on my i5 server.
Any ideas ?

f16 - locked out again
by Robert Moskowitz
This happens once in a while, but this is the 2nd time this week, though
the symtoms were different.
The latest occurance, I locked the screen <ctl-alt-l> and came back
later to use the system. I hit an arrow key which normally brings up
the password dialog box and even before the box showed up I started
typing in my password. This normailly works fine and opens up to the
workspace I was last on.
This time nothing happened. There was a flash across the screen like
the dialog box coming up, but the screen stayed black other than the
portion of the top panel that normally shows when the screen is locked.
I was able to <ctl-alt-F2> to another console and back. I tried
<alt-F1> then 'r' and saw the spindizzy but nothing after that. In the
end, I rebooted by logging into the F2 console. Perhaps I should have
done a tail on messages first?
Various things have happened over the past month on f16 with gnome 3.
Not coming out of suspend and having to ppull all power for a hard boot
recovery (AC and battery). Gnome locking on me with no keyboard or
mouse clicks, though the mouse will mouse around.
So it is still unstable for me.
Advise on trouble shooting?
Oh, and to the point of pulling the battery to get to a hard boot
state..... My brother-in-law was talking about his recent purchase of
a notebook with a sealed battery; ie he cannot remove it. His question
was on which kind of warranty to get. But now my question is: does
anyone have a notebook with a sealed battery and if so, how do they
recover when nothing works? When you cannot switch to another console
and the power button does nothing? How do you force a boot if you can't
pull all power?

gscan2pdf problem
by SternData
I have an HP 8500 printer/scanner and am trying to scan from gscan2pdf.
When I initiate a scan, the paper is fed from the document feeder, but
no content is transferred into it.
Scanning from xsane works as expected.
Any ideas?

About expelling "Linda" and similar people

As far as "Linda" is concerned, she (?) really, really felt to me from
the very first moment as nobody else than the K. Larsen guy who messed
up around here and on Ubuntu lists till one or two years ago, with
another address. But this is just a personal feeling, not supported by
any fact, only reported for your amusement.
Apart from this, I've tried to ignore this issue for as long as I
could, but apparently isn't possible anymore. I am against general
moderation here for a lot of reasons, but I am all for expelling
subscribers like these quickly, every time they appear, period. I
can't understand why it didn't happened weeks ago.
Arguing that one should be "patient with newbies who come from
Windows", as somebody wrote in defense of "Linda" weeks ago doesn't
make sense. Being a Windows user and/or a total newbie, and being a
totally annoying, group-destructing moron are totally separate issues,
why should the first be an excuse for the second?
The reason why people like these should be expelled is that they do
kill communities, but (also) in a way that I haven't seen mentioned
yet.
What makes one distro different from another is (among other things,
of course) the effectiveness and usefulness of its mail archives and
the effort it takes to follow them for a newbie.
Personally, I have NO problem at all to filter out everything about
"Linda". I do filter out uninteresting mailing list threads all the
time anyway with this great procmail trick I invite everybody to try:
http://freesoftware.zona-m.net/how-ignore-uninteresting-threads-in-mailin...
In spite of this, "Linda" still is killing this list because the
archives are full of crap from/about her. What recent archives tell
now is not "how to use fedora". It is:
a) if you want to get or give help here you have to set up special
filters, because no Fedora person cares about making your mailing
list usage as smooth as possible
b) if you want to learn something by browsing the archives, learn
first to do without **any** thread in which "Linda" appears, there will
be nothing but noise in there.
Even if there are never personal attacks, a community with a mailing
list whose inboxes and archives are free playgrounds for Lindas looks
like a restaurant whose owner won't kick out customers giving speeches
from their table because "ear plugs are so very easy to use".
This is the main reason why years ago I stopped trying Debian AND made
a point to NEVER recommend Debian to anyone. Three or four veteran
subscribers regularly used the list to ramble for days about
EVERYTHING that crossed their mind, filling both inboxes and archives
with hundreds (literally) of messages of irrelevant stuff. They would
explain you how to set up a firewall, then drop in some memory of
college in the same paragraph and ramble along for days.
the moderator wouldn't care and if anybody tried to tell them to stop,
he would be doctored both by those morons in a very Linda-like style,
and by other subscribers, that they could ramble as they pleased
because "it is very easy to filter me out, just set up your procmail
like this..."
So, no to actual moderation, but as soon as some character like this
PROVES he/she won't stop as Linda abundantly proved, block him for
good, please.
