Using ionice -c3 in f13: system seems less responsive than under f12
by John Pilkington
Hi: My system spends a lot of its time processing video data, often
with not much numerical processing involved - just remuxing or making an
iso image. atop often shows disk activity above 90%. I do most of this
using ionice -c3, (ie 'idle' scheduling) which is supposed to reduce
impact on other tasks. The man page says "The impact of idle io
processes on normal system activity should be zero" and certainly
under f12 that seemed at least approximately true; but under f13
terminal response is often very sluggish when these tasks are running.
Using kde 4.5.3, scheduling elevator=deadline (as in f12).
Am I expecting the right thing? Does anyone else see this?

F12 -> F14 (via preupgrade), not so smooth
by Kevin Cummings
Last night, after I successfully upgraded my F13 test desktop from
F13->F14 w/preupgrade, I started the same operation on my F12 laptop.
The results were not so good.
X86_64, Asus S96J laptop, w/ATI Mobility Radeon X1600 video card,
IPW3945, 2GB RAM, 350GB disk.
1) I had recently installed WICD (from ATRpms, so shoot me) because it
worked better for me than NetworkManager under F12. Under F14, it fails
to start properly (yes, its the fc14 version now). So, I disabled it
and re-enabled NetworkManager. I have networking back for now.
2) X11 no longer starts up. I'm using the radeon driver for my ATI
Technologies Inc M56P [Radeon Mobility X1600]. It was working just fine
(as fine can be with the radeon driver), but now it dies with a seg
fault with only 3 frames on the stack. I have re-configured to run the
VESA driver, but, I miss my 1200x800 native resolution. VESA can only
do 1024x768. I can attach my (used to be working) xorg.conf for anyone
interested, but it fails in exactly the same way if I delete it as well.
I can try again and send along an Xorg.0.log if it will help.
2a) VESA has lots of problems returning to a proper video mode. If I
run dosbox in full-screen mode, when it returns to X11, the resolution
is less than stellar. Its the same size, but it seems like every other
pixel is missing. Heck, All I have to do is switch to a diferent
virtual console, and X11 is hosed when I return to it. Even the color
pallette seems to be changed. I have to logout and restart the X server
to get it back.
3) VMWare-Server won't compile. Seems it can't find the kernel
headers. Its looking in /usr/src/linux/include, but that directory
seems to be missing. (I built it successfully a number of times under
F12.) I have kernel, kernel-devel, and kernel-headers installed. That
used to be enough for VMWare-server.
4) There are a number of python errors during bootup. They are not in
DMESG.
5) the console screen during bootup contains lines starting with [ [
mmm.nnnn ] messages that were not visible on F12. It makes looking
at the [OK] and [Failed] service messges difficult.
I'm sure I've missed something else (I haven't tested suspend/hibernate
yet), but for now, this is what I've noticed.
Imagine my surprise at No Network and No Graphics after completion of
preupgrade. Not a lot of fun.
I still have an F11 server that I need to upgrade, but not until I get
my laptop's problems sorted out.
And, for those of you who are still reading, yes, I have read both the
F13 and F14 release notes, but nothing stands out (to me) that I may
have missed.
Suggestions welcome.

OOo and delta RPM
by Ron Yorston
Is there a problem with openoffice.org and delta RPMs? I've just
done a yum update on F14 and all the OOo packages were downloaded in
their entirety, whereas about 30 others came in as deltas. And it's
not like OOo is small. And this is the second update in a week.
If it's going to carry on like this I'll exclude OOo from updates:
I only use it once in a blue moon to examine documents in proprietary
formats.

ltsp-5.2.4-1.rpm Coming soon to Fedora !!!
by Gavin Spurgeon
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi LTSP/Fedora Community.
(1st let me say "Sorry for the X-Posting to multiple Lists")
I would like to take this opportunity to say that Myself and a friend
have stepped up and I will now take over trying to keep LTSP in Fedora
Current with the upstream.
@ the end of last week I was given access to the LTSP Package on Fedora.
I have the src of ltsp-5.2.4 and am in the process of getting this into
and .rpm for Fedora 13 & Fedora 14 (x86 & x86_64).
This is going to take a little bit of time to get this release into an
.rpm, but we hope to have this done within the next week or so...
I first need to get my head around how the current version is packaged
and then we should be able to get the new version packaged the same way
to try and make this all as seamless as possible.

Build custom Xen Kernel
by Kostas Sfakiotakis
Greetings ,
I have a Fedora 14 64 bit installation running on a machine with a
dual core AMD 64 bit at 3,00 GHz cpu ,
2 GB of RAM and a lot of hard disk space ( the Fedora installation
resides on a 1,5 TB hard disk drive ) .
I have succesfully installed and run a virtual machine running Windows
XP Professional under QEMU but
now i wanted to do it with Xen . I have google for it and it seems that
the first thing am missing is a Xen
kernel . Since am quite new on this thing i was wondering if there is
somewhere a step by step guide with
instructions on how to install and run a virtual machine under Xen
instead of QEMU .
Kind Regards ,

flash.exe files
by Hiisi
Hi, List!
Correct me if I'm wrong, but there's no way to run windows exe flash
movies under linux without wine? I have a foreign language video
tutorial packaged for windows users. On the course dvd there's all data
(video lessons, images and texts in xml format). Testing it under
VirtualBox windoze xp reveals that main executable (start.exe) opening
flash player with different menus and buttons. Without that it's
difficult to organize all that stuff in right order. However performance
of video under VirtualBox is very poor. And I don't want to install wine
on my machine. It would be a big hole in security. So, any suggestions?
TIA

Fedora 14, wireless keyboards and encryption
by Chris Northwood
Hi there,
So, I'm having a problem with my Fedora 14 setup. I've recently
installed the distro on the machine, and set up full disk encryption
using the standard method in Anaconda. However, on the passphrase
screen (the one which appears as the OS starts), any input on my
wireless USB keyboard (this one:
http://www.maplin.co.uk/Module.aspx?ModuleNo=223792) doesn't work -
there appears to be no response to input from the keyboard. If I
connect a wired keyboard (this isn't a long-term solution, however -
the box is to become a media server, hidden behind my TV), then I can
enter the passphrase and continue just fine - once I get to the normal
user login screen, then I can enter my password and log in then. I
don't believe it's a BIOS problem as I can use the keyboard to
navigate around the BIOS setup screens no problem.
I did set up my machine using the wired keyboard, and only changed to
the wireless one at a later date, so I'm wondering if some relevant
kmod is missing when it's required, or something like that.
Any help to get my wireless keyboard up and running so I can enter my
passphrase with it would be much appreciated!
Regards,
Chris Northwood

Installing Openshot video editor
by orschiro@googlemail.com
Hi guys,
I'd like to install openshot. As it is not available in any repo I
picked the rpm package from here.
http://killobyte.com/openshot/
Unfortunately it needs python2.6, giving me the following error:
mlt-python-0.5.4-1.fc14.x86_64 requires python(abi) = 2.6
openshot-1.2.2-1.fc13.noarch requires python(abi) = 2.6
I'm using f14 so there's only python2.7 in the repos. Where could I
find python2.6?

Firefox and Opera on FC14 fail to access Globus site
by Abu Attar Musharih
Hello List,
I have two browsers, the Firefox and Opera on F14. Both can watch
without any problem
youtube videos and access almost any site except for Globus (
http://www.globus.org/ ). Using the Firefox of F7 on another box, I
found no problem of accessing that site.
Does anyone have an explanation?
Thanks in advance.

FC14 good/bad news
by Bill Davidsen
I installed FC14 in a VM, on a 7.7GB disk image. After that was installed and
tested to some extent, I copied the image to an 8GB SD memory and booted off it.
Worked with the micro-SD in an adaptor to full size SD, and in a micro-SD to USB
nubbin. When I installed I made the filesystems ext2 to avoid beating the
storage, other than that stock install.
Now I can select enhanced effects for video, and they work fine (for values of
fine considering I wanted to see if they work, not that I want them on).
However, the display is still dog slow, glxgears runs at 60fps, video is jerky,
etc. So the "better" video now doesn't crash, does provide effects I don't need,
and is still too slow to be useful, even on a non-game machine. So much for not
using vendor drivers.
System is i7-950, 12GB RAM, Radeon HD 4350 video, used as a VM host most of the
time. Not a killer machine, not a dog.
I will be doing some testing to see if the newer KVM is any better in a
measurable way, but when VNC to a machine with fast video is better than
console, there is room for improvement.
