I can't find the preferences menu for Nautilus in GNOME 3. But gsettings works.
To set the default sort order:

gsettings set org.gnome.nautilus.preferences default-sort-order name

To show the directories first, before the files:

gsettings set org.gnome.nautilus.preferences sort-directories-first true

It works :-)

I was trying to reuse and old disk by adding to LVM. The error appeared when I tried to use pvcreate. I had already created the type 8e primary partition on the disk and rebooted, but still got the error.

First, download the IBM Java SDK from http://www.ibm.com/developerworks/java/jdk/linux/download.html
Install java (by running ibm-java-sdk-7.1-0.0-x86_64-archive.bin as root) into /usr/lib/java/ibm-java-x86_64-71.
Change the alternatives links by running:

insmod ipt_mark
This is what I have:

insmod xt_mark
iptables -t mangle -A PREROUTING -i ! `get_wanface` -d `nvram get wan_ipaddr` -j MARK --set-mark 0xd001
iptables -t nat -A POSTROUTING -m mark --mark 0xd001 -j MASQUERADE

This was recommended...
In all builds newer than 17000 this script needs to be in your firewall if you have 2 WLAN's:

iptables -t nat -I POSTROUTING -o `get_wanface` -j SNAT --to `nvram get wan_ipaddr`
iptables -I FORWARD -i br1 -m state --state NEW -j ACCEPT
iptables -I FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu


How I got wally working on Fedora 18
Install prerequisites:
sudo yum -y install qt-devel libX11 libX11-devel cmake gcc-c++
Get source from SourceForge
Extract the tarball: tar -zxvf wally-2.4.4.tar.gz
Enter the directory: cd wally-2.4.4/
Go into the build directory: cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-lX11" ..
make
sudo make install

These are the settings of my zoneminder capture cameras.

As root:

ln -s /usr/share/applications/gnome-appearance-properties.desktop \
/usr/share/gdm/autostart/LoginWindow/

Logout.
The properties window is shown when gdm restarts.
Here's a new way to do the same thing, but easier:

xhost +local:gdm
sudo -u gdm dbus-launch gnome-appearance-properties
xhost -local:gdm
