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.

I have recently upgraded to Linux Mint 15 Cinnamon 64bit and I keep getting a message on my screen at startup telling me that I have no video acceleration ...
I didn't have this problem with LM14.
How do I switch on Video Acceleration?
My graphics is Intel GMA HD series.
The message on the screen says, "Running in software rendering mode".
The whole message says, " Cinnamon is currently running without video hardware acceleration and, as a result, you may observe much higher than normal CPU usage.
There could be a problem with your drivers or some other issue. For the best experience, it is recommended that you only use this mode for troubleshooting purposes."
Incidentally, the gaming test ran perfectly although I wasn't quite sure what it was supposed to do

I think it just tests the video acceleration. If it looks normal then I guess it passes the test. If Mint is constantly whinging for no good reason, switch to Debian or at least LMDE.
Your not going to believe this ... I installed another desktop environment, in this case XFCE as it's fairly lightweight, and the "Message" problem disappeared. I switched back to Cinnamon and the "Message" no longer appears ... Talk about weird
The two commands I use to test for video acceleration are:
glxinfo | grep direct
The second one shows gears spinning, and gives your FPS reading. It's stopped by pressing "q". If the FPS reading is lower than it should be, then there's a problem. Try it on Mint, and then on another distro (IE, run by Live CD) and see if there's a difference. If not, then there is no problem (though, from the sound of it, it seems you've solved the problem anyway, so good!)
