When executing the apt-get update command, you may get “There is no public key available” warning message. This article explains how to solve this warning message message.

If you are running a different Linux distro or don't have the Fedora CD, I'm pretty sure you can use a different Linux bootable CD like Knoppix and then just install the LVM tools (How to install LVM tools on Knoppix) and use that instead.

So, once you're at the command prompt, you need to activate the LVM partitions so they can be used. This can be done using the following command:

lvm vgchange --ignorelockingfailure -P -a y

I am running Ubuntu 8.10 with the Kubuntu packages installed. I use switch between ratpoison and kde and so I sometimes manually configure /etc/network/interfaces. When I went back to KDE I had lost of trouble getting my eth0 and eth1(wifi) connecting. Under network manager it said that eth0 was disconnected and eth1 was unmanaged.

I read this thread and decided to rename interfaces. I had to restart X to get it to take affect, but this gave control back to network-manager.

I will probably have to write a script to change out interfaces when I switch between windows managers.

There is an awesome program called firelight.

Installing Centos 5.2 x86_64 from DVD on a Dell the system hangs in the window Loading SCSI drivers with the message "Loading ata_piix driver.

If you Ctrl-Alt-F4 you can see the sata drives being retried over and over at lower and lower speeds.

You can disable this by editing a file and entering two simple lines.

vim /etc/modprobe.d/blacklist

And then add:

blacklist pcspkr

Save your file and the speaker beep will be gone when you reboot.

If you don’t want to wait until a reboot, simply type:

sudo rmmod pcspkr
