Where is 2.6.32?
by Konstantin Svist
How come Fedora is still on 2.6.31? Is .32 held back on purpose or are
there issues merging it?
It took less than a week for .31.9 to be pushed through... but I don't
see .32 in updates-testing and it's been almost a whole month...

Between F11 and F12, which would you choose?
by Reg Clemens
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.

SMS server/gateway
by Jamie Bohr
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
rx_missed_errors.

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.

Local cache / 'repo' of updates and added RPM's
by JayLinux
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 (
http://aptoncd.sourceforge.net/)
APTonCD is a tool with a graphical interface which allows you to create one
> or more CDs or DVDs (you choose the type of media) with all of the packages

Thanks,
Jay

changing GDM background image on F12
by Fred Smith
Hi!
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.

KDE menus slow to appear when using VNC, but OK local
by Lets Go Canes
Hi all.
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?

Disk usage error
by William John Murray
Hello all,
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.
Thanks,
Bill

random lockups when using Firefox
by Julian C. Dunn
Hi,
I have a F12 box that periodically locks up solid when visiting certain
Flash-based sites in Firefox. There are usually no odd messages found in
/var/log/messages to indicate what went wrong, except a couple of days
ago, after a crash, I found this:
Dec 29 13:01:50 jupiter kernel: [drm:radeon_fence_wait] *ERROR*

(etc.)
My video card is a:
02:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60
[Radeon X300 (PCIE)]
Could there be some bug with the radeon driver that is causing this?
