Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

this is the problem with automated software that has no customizations, without dual layer k3b seems to have no dual layer capeability, there is no user setting I could find that even huinted at dual layer, is it safe to assume that you do new dvd and it just shows 8.xgb instead of the 4.xgb? or is there a dual layer dvd option as well as the usual cd and dvd options?
k3b hides *software* dual layer capeability so that you cannot see that it *would* support dual layer *if* you had a dual layer drive correct? or is *software* dual layer capeability completely transparent to the user, if so how then would it work?
this is in contrast to command line utilities which have a --help and man pages describing all areas of functionality regardless iof weather you meet the hardware requirements, thus allowing you to check and see if the software would support the hardware before you actually buy it. thus my point is that software apps liek k3b that do everything for you leave you hoping and praying that if you buy the drive that the required options in the software would magically appear.
when I do new dvd in k3b it shows xxx of 4.xgb, if I go over it turns red, leading me to beleave it has dvd'as are only 4.xgb. this is before I specify wehat drive or query any media, so it is not simply reading 4.x disk, show 4.xgb, now, when you burn a dual layer dvd more than say 5gb does it show the usage bar in red? or does it query all the drives to see if any are dual layer?
In k3b, go to Settings -> Configure K3b -> Devices
Scroll down and looks for "Writes DVD-R Dual Layer" and "Writes DVD+R Dual Layer"
If you do not see either option, you need to upgrade k3b. If you do see that option listed but BOTH are "no" (I've never seen DVD-R DL, incidentally) then you may need to upgrade your cdrecord package, or depending on your burner, switch to a different device. I have a cheap reliable Lite-On and dual layer capability is recognized for that drive. What model drive do you have? What version of cdrecord do you have installed?
I've been able to sucessfully burn dvd -r dual layer only with nerolinux. I'm using Ubuntu and run both 64 and 32 bit operating systems dual boot. But the results are kind of buggy and I don't like how the proprietary nero interface is so totally non integrated with the rest. If you are desperate this is the only solution I have found. But as I say it is buggy - the disk after being burned takes a long time to mount and doesn't always work. Kind of unacceptable is you are doing -forinstance- a crucial backup.
I've read that dvd+r dual layer is more likely to be supported. I plan on buying some and giving it a try. I started with the -r dual layer because that is all the local store had and my experience from normal (single layer) dvd's that dvd-r is very sucessful and supported (by such things as nautilus, k3b)
Can anyone confirm who knows more about this that dvd+r dual layer is the way to go for linux?
If you need to use nerolinux just search that term on isohunt and there are many copies for *free trial* I wonder how the proprietary nerolinux succeeds (though not 100% consistently) Perhaps they are using some open source tools we aren't thinking of... Or perhaps they are "Ahead" of the OSS development and someone should try to study their method to develop one for the free world.
