Interpreting iostat results for raid
by Madhav Ancha
Hi,
As a result of running this command, 'iostat -x -m 30 30'. I get the
following output. sda and sdb are sata3 drives in a striped raid (0).
How do I interpret these results for a raid. Specifically,
a) await to svctm ratio is close to 1 for individual drives but > 2 for
dm-x.
b) I expected to see rMB/s closer to 300 which is the SATA3 speed with
the reasonable good disks I am using. But these are at 1.xx MB/s. What does
thie mean?
c) What's the interpretation to monitor the raid performance? Seems like
there is enough bandwidth for I/O here but when I bump up the processes just
a notched, there is a long await to svctm ratio.
Thanks,
Madhav.

F12 and system-config-display on nvidia fx5200
by Joachim Backes
Hi,
In previous Fedora versions I was successfully using kmod-nvidia-173xx
(from rpmfusion-nfree) together with my fx5200 video card. When first
installing F12, the nouveau driver was installed for graphics, and no
kmod-nvidia-173xx was available.
In the meantime kmod-nvidia-173xx became available, and after
downloading and installing it I wanted to configure my video card with
system-config-display, which fails each time I try to run (see bugzilla,
there are a lot of bug reports for system-config-display in F12).
Question: is there another way than the usage of system-config-display
for configuring my video card for the nidia-173xx driver?
All hints are welcome.
Kind regards

VDQ fullscreen
by Beartooth
One machine has the background pic switched to fullscreen (I
think; I never go near putting anything into that.), or at any rate
doesn't show either my bottom panel or my left panel. How do I get out of
this display and get my panels back??

Brasero multiple disks
by SternData
Brasero seems to have a feature to let one burn multiple disks when the
content is to large to fit on one.
I selected about 40 MP3 files for an audio CD. Brasero correctly notes
that that's too much for one CD. A button appears that says "Burn
Several Disks". Sounds good. But, when I click it, there's no BURN
button. How do you actually get it to burn several disks?

Then I must fill a bug in Fedora or Gnome bugzilla ?

KVM reboot fails
by Seann Clark
All,
I have been searching google for about two weeks, and looking over
everything else and I just can't figure this out, so I am polling on the
greater combined experience of the list to help me out with this.
I have recently set up a virtual machine under KVM, which runs fine
on my system. The problem is, I can't reboot the system, nor can it
reboot itself. The Guest is running Windows 2008 Standard, and instead
of shutting down, or rebooting, after it is all done, it goes to a
BSOD, which only happens when it is trying to reboot. If I try to do
this from virsh I get the error:
libvir: error : this function is not supported by the hypervisor:
virDomainReboot
The host running the VM's is fedora 9 64 bit edition, that I haven't
gotten around to upgrading yet (patch management is EOL, or very close
to EOL, so upgrading is something I have been working on getting done)
virsh is version 0.5.1 and qemu-kvm is version 0.9.1 (kvm-65).
Outside of sucking it up and upgrading, which is what I figure would
need to be done, I would like to try to understand why this is having a
problem. If I can fix this, I can take my time and fix other issues that
are preventing me from upgrading properly instead of being rushed.
Thanks in advance,
Seann

SELinux alerts concerning tmp_t and mount_tmp_t
by Henrique Koesjan
I have lots of SELinux alerts like this one:
SELinux denied access requested by abrtd. /var/tmp may be a mislabeled. /var/tmp
default SELinux type is tmp_t, but its current type is mount_tmp_t. Changing
this file back to the default type, may fix your problem.
Daniel J Walsh solve the trouble for me using this command:
chcon -R -t tmp_t /var/tmp
but every time I started my computer the trouble is back:
I remember having add these lines to /etc/fstab:
#### RAM Drives ####
tmp /tmp tmpfs rw,mode=1777,fscontext=system_u:object_r:tmp_t:s0 0 0
vartmp /var/tmp tmpfs rw,mode=1777,fscontext=system_u:object_r:tmp_t:s0 0 0
Is this the reason for the SELinux messages? What am I doing wrong?

xrandr w/ laptop and ext monitor
by Joseph L. Casale
I have an HP laptop w/ an Intel chipset and am trying to clone the laptop display to an
external lcd but not having luck. I want it to appear exactly as is (task bar etc) but with
the obviously different resolution, can anyone point me to a doc that suggests this config
versus that of extending etc?
Thanks!

missing HP printer drivers for PSC 12xx series?
by Jud Craft
My Hewlett-Packard printer-scanner-copier 1210 auto-detected and
installed automatically just fine in Fedora 11.
In 12, it says "can't find driver for HP Series 1200 PSC" or somesuch.
Clicking "search" on the alert shows the giant vendor list of
drivers, and sure enough, the HP PSC drivers stop at 900.
Have they been moved to another package?

Anyone have Java working with Chromium
by Patrick O'Callaghan
I've been using the Chromium browser under F12 on my netbook for several
days, and generally like it a lot (especially on the small screen). It's
fast and doesn't eat RAM like Firefox.
*But* Java sites don't work. This is a known bug with Linux versions of
Chrome/Chromium but I wondered if anyone out there had managed to get it
to work. I'm using IcedTea. Would it make a difference with Sun Java?
