GNU/Linux Desktop Survival Guide

Dell OptiPlex 740 (Kyral)
Kyral is an AMD64 desktop and server with 4GB of memory, a 250GB hard disk, a DVDRW dual layer burner, and nVidia GeForce 6150 video chip. The machine came with MS/Windows Vista installed so the machine was set up for dual boot (an option during the install).
A default install using the Etch (version 4.0r0) release of Debian
GNU/Linux, booting from DVD-RW, was performed . The DVD
image was obtained using jigdo-file, running the command
jigdo-lite (see Section 3.6.2) and specifying
MD5 checksums confirmed the integrity of the downloaded DVD image, and
similarly for disks 2 and 3.
The non-free nvidia driver was required, which is quite a downside--we should avoid the nvidia graphics chips until they provide open source drivers. Each time the kernel is upgraded we need to recompile the nvidia module 
Ubuntu Karmic was later installed as a clean install (after backing up the hard disk and restoring what was required . This was upgraded to Ubuntu 12.04  and a clean install of Ubuntu 13.10 . Unity 3D had issues (slow and the nvidia proprietary drivers kept freezing) so Lubuntu was installed and has worked well.
