I have a half dozen machines updated to F11, and one to F12.
Im wondering if I should update the F11s to F12 or leave well enough alone.
I realize that the F11 distribution has reached a 'stable' status, and
the F12 distribution will probably take a couple more months to reach
that status, but would be interested in hearing what other users have
to say about the pair.
I am looking for a SMS server software for RHEL.
The phones we use can receive email but it does not always get to the phone
in a timely manner and sometimes I get "connected refused" when trying to
send messages via email. I've looked at smstools and Googled around but
would like the forums opinion on what they have used and experiences.
Thank you for your time,

I'll try these suggestions later today. Note that I was able to disable
interrupt throttling on the on-board 82574L NICs without seeing any

We run "mpstat -P 5 ALL" continuously; is this sufficient resolution? I've
attached the mpstat output from the 09:30-10:30 yesterday, which is one of the
busiest hours of the day for multicast traffic.
Also, here is the top of the output from powertop. Are you running with C-STATE
enabled? It is somewhat troubling that more than half of the time is spent in
the most power-saving state (C3), but I think this is averaged across all CPUs.

I had to re-install Fedora 10 on a home desktop PC. In regard to this:
Is it possible to have a local cache/ "repository" of all
1) Updates (Critical, Security, Bug-fixes), and
2) Additional installed rpm's (that were installed through PackageKit), e.g.
Opera, Adobe Reader, etc.
so that I do not have to download all those again (800 MB + D/L)
This would be similar to the 'aptonCD' package in Ubuntu (

I've looked thru the forums and done some googling but I don't see an
answer THAT WORKS for this question:
How to change the default GDM background/wallpaper to some other image?
I've tried all the things listed in the forums and none of them works,
including (but not limited to) copying the image I want into
/usr/share/backgrounds/images then running this command:
gconftool-2 --direct --config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults --set --type string "/desktop/gnome/background/picture_filename" "/usr/share/backgrounds/images/Fistmaster.FullHD.0190.jpg"
having done that either log off or reboot and voila! no change at all! :(
Thanks in advance.

I am having a problem on a laptop where the KDE "kickoff application launcher" takes several seconds to appear after it is clicked - 30 to 40 seconds would be typical. The same problem exists with the "lock screen" and "shutdown/logout" widgets that I have added to the taskbar. The problem only occurs over VNC - it does not occur when logged-in to the laptop directly.
The problem would seem to be similar to the one discussed at http://forums.fedoraforum.org/showthread.php?t=234227 , with the following differences:
o problem occurs on a VNC display, but not on the laptop's LCD
o system uses the radeon driver, not nvidia
o system has xorg-x11-server-Xorg.i686 and xorg-x11-server-common.i686 1.7.4-1.fc12 installed (I tried 1.7.4-4, but it didn't fix the problem, and "broke" the laptop display)
Has anyone else seen anything similar, or have any suggestions?

Can anyone help me with a disk usage problem? I have a disk
partition of 65GB in LVM; df says:
/dev/dm-0 65570580 60494828 1744888 98% /
However, if I use either du or Baobab they reckon the directories in it
add up to 30Gb or so. As it is my root directory, and there are various
others it is a little difficult to get the total, so I booted under
liveUSB and saw exactly the same - 30Gb used, but 98% full.
So something is stealing half my disk. If I try to write more it is
out of space.
Any ideas how I get my space back? fsck reports the disk is clean.

Could there be some bug with the radeon driver that is causing this?

On a new Fedora 12 install how can one add libraries and applications
for Xubuntu (i.e. add the Xfce Desktop with it's apps) ? Am using
GNOME as the desktop presently.
