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.

So I just installed Ubuntu 10.10 on a computer attached to my TV.
I have an issue.
If it is connected via HDMI the the desktop area is 1920x1080...
the top and bottom task bars are not displayed on screen but i know they are there because i can click on top left corner to get the menu.
If I use the VGA cables, I can see the entire thing(the top and bottom task bars are there)
Same exact problem, but I can say mine did it also with 10.04, so I uninstalled it and went back to Windows XP (fresh install there also).
I would like to ditch Windows XP, where it worked fine on the HDMI. Would love to make Ubuntu 10.10 my media center operating system, but it seems the screen is just a tad large and truncates all 4 edges just a bit (enough that the menus are not visible).
As with the original poster, you can click in upper left corner off the screen and then you can see the resulting menus.
Will post more info when I get more details, like video card and if the same happens at 720p.
I had a similar problem with Debian testing and a Samsung SyncMaster 2494HM when using HDMI (previous use with a VGA cable with no problem): at 1920x1080 the screen was truncated and the picture was not completely neat.
In fact, the problem was neither X.org nor Linux but the Samsung display itself. For a reason I ignore, two options were checked in the screen configuration (that can be changed thanks to the OSD menus and the buttons on the screen):
- A/V mode was ON, I disabled it and the picture became very neat and nice
- Image Size > Scan adjust was ON, I disabled it and then the picture correctly fitted the screen
