Enabling Airport wireless on Macbook Air with F12
by Colin Paul Adams
Thanks to Chris Smart, Peter Danenberg and others, I have been able to
install Fedora 12 as the sole O/S on my Macbook Air (first
generation).
However the wirless networking is not enabled.
I am following the instructions in
http://docs.fedoraproject.org/wireless-guide/f12/en-US/html-single/#chap-... .
There was no wireless device shown in the network Configuration, so I
clicked New and added a device for hardware Apple Airport.
I also tried adding wireless device on the Hardware tab (eth0), but although
it allows me to do this, after I save and then reopen the Network
Configuration, the hardware only shows a device pan0 of Type Ethernet
(which was there from the start). It does appear on the Devices tab
(it didn't originally until I added it), but has staus of inactive,
and no means to activate it.
However, even after restarting the computer, the wireless icon on the
panel says there are no network devices available.
So I tried removing the device from control by NetworkManager, and
activated it manually. But then I get:
Device eth0 does seem to be present, delaying initalization.
What do I need to do?

Problem with an external usb HD - slow usb
by Luigi Castro Cardeles
Hi list,
I use fedora 12 on a dell inspiron 1545 laptop.
(2.6.31.12-174.2.22.fc12.x86_64).
i have a external usb hd and i can't make it connect like a usb 2.0 device.
this device is ntfs format
I check if the device is using ehci (dmesg after i plug the device)
[root@localhost ~]# dmesg | grep USB
usb 2-2: new high speed USB device using ehci_hcd and address 2
I check if this device is connected on a usb 2.0
[root@localhost ~]# lsusb
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 015: ID 0471:2021 Philips
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I mount the device with this options:
/dev/sdc1 on /media/hd_backup type fuseblk
(rw,nosuid,nodev,allow_other,blksize=4096)
but when i use cp, mv or rsync, the max speed i get is max 6MB/s (a lot
800kB/s).
If i use this device on Windows (tested with Vista and Seven), i get much
high transfer rate.
I read about sync and async options, but if i put sync or async on fstab, it
does not alter the transfer rate.
Is this the normal upload transfer rate? I am doing something wrong?

Kernel boot problems or is my hard drive failing ?
by linux guy
If I power down my laptop via the usual KStart->Shutdown means, it can
take up to 4 restart attempts before it fully boots.
It has no problem launching grub and the kernel selection screen. That
it does reliably every time. After that, there are issues.
Twice I will get a back screen with a flashing cursor. Then I will get
an ehci -19 error. Then it will boot properly.
My fscks are fine. I had a block error once, about two weeks ago, but
that was with an older F12 kernel after completely crashing during a
resume from suspend to RAM.
Is anyone else experiencing a problem booting ? Does this sound like a
kernel problem or is my hard drive failing ?
Thanks

Vinagre???
by Antonio M
I have two boxes, both have UltraVNC and Vinagre (Remote desktop
viewer), exactly the same packages both in F11 fully updated
When I connect from A to B both Vinagre and UltraVNC work, but when I
connect from Ato B UltraVNC works fine but in Vinagre I see the list
of remote desktops, but when I try to connect I get the message
Connection closed: The connection to host B has been closed.
Any idea??
Tnx

assertion in NetworkManager

Hello @all,

Fedora 11 GDM - unwanted list of all local users and impossible to customize?
by jaivuk
Hello guys,
I did not use gdm for some time and now I'm not happy how it looks in Fedora
11.
First of all - the list of local users is unacceptable from security
reasons. Even if it supports such "an " option - how it can be the default
one?!
Second problem I have is shutdown button (and possibly restart as well) -
when you click on shutdown button by mistake, system will shut - there is no
confirmation dialog.
I also tried to find some ways how to customize gdm in Fedora 11 but I did
not find any usable guide.
Can anybody please advise me how can I have prompt asking for username only
(showing last logged user at maximum) and not displaying the list of all
local users?
Also can I somehow add confirmation or remove shutdown restart buttons from
gdm screen?
Or can you please advise any alternative to gdm?
Thank you very much,
Jan

Fedora 12, Xorg, and Apex Outlook KVM, - can't nail resolution
by Styma, Robert E (Robert)
Hi,
I've been looking at this for some time in both the
archives of the list and the web in general. The problem
is that when my Fedora 12 machine is connected though the
KVM (Apex Outlook 8 port) the monitor shows up as "Unknown"
and the resolution is limited to 800x600.
If I plug the monitor directly into the machine, it resolves
just fine and I have the full range of resolutions.
I tried an number of things so far and the one which seemed
most promising was to plug the monitor directly into the
machine and go to run level 3. I then ran "xorg -configure"
which created /root/xorg.conf.new (I may be remembering the
syntax of the command incorrectly). I copied that to
/etc/X11/xorg.conf and uncommented the NoDDC option with the syntax:
Option "NoDDC" "True"
Unfortunately the results are unchanged. The Xorg.0.log appears
to show that the xorg.conf file is being read, but it goes out
and probes the monitor anyway.
http://www.styma.org/xorg.conf
http://www.styma.org/Xorg.0.log
I have put the xorg.conf file and Xorg.0.log out at my web
site in the hope someone can give me a pointer on how to
make X use what I tell it in the xorg.conf file and not
do the probes itself. Note that my Fedora 6 machine, Redhat 9
machine, sparc 20, and assorted Windows machines work
fine.
I appreciate any time and help which can be offered.

Rendering chart from bootchart
by Suvayu Ali
Hi everyone,
I have been seeing very long boot times for the last few months so I ran
bootchart. But I can't render the chart after booting. The web interface
seems to be down. And the java application supplied with bootchart
generates the following error.

What seems to be wrong?
