gnome-tweak-tool to change Gnome 3 Settings

[Updated 2013-06-20]

You can modify the gnome settings using gnome-tweak-tool

E.g. The clock/date settings
If you want to show the date in the clock on the top bar:

1. Launch the gnome-tweak-tool
2. Go to the "Shell" menu
3. Enable "Show date in clock"

Fedora 17: em1 Instead of eth0?

Network Interface Controllers (NIC) that are embedded on the motherboard are identified by udev as em1, em2, etc. This is part of an attempt to make interface naming more predictable and meaningful.
That's what you will find instead of eth0, eth1, etc.

To get back the old name go to: /etc/default/.
There you'll find the configuration file for the default Fedora boot loader, GRUB: grub

Add the following command (bold) to the line with the key GRUB_CMDLINE_LINUX:

GRUB_CMDLINE_LINUX="rd.md=0 rd.lvm=0 rd.dm=0 SYSFONT=True  KEYTABLE=us rd.luks=0 LANG=en_US.UTF-8 biosdevname=0 rhgb quiet"

Go to /boot/grub2, make a backup copy of grub.cfg and regenerate the GRUB configuration file:

> grub2-mkconfig -o grub.cfg

Reboot and eth0 will be back!

Hints here and there.
