Live Knoppix Is Very Nice Desktop Linux

Cheat Knoppix 4 to Improve Performance

Part 4. Computer on a Disc and a USB Key

The Knoppix live CD or live DVD together with a USB Key and the persistent Knoppix trick pretty much give you a portable computer on a disc and USB key. Considering that you can download the Knoppix live CD or live DVD at no cost, the only thing your Knoppix portable computer costs you is the price you pay for your USB key -- and that can be as little as $25.

How to Boot Persistent Knoppix

If you want to use your persistent Knoppix image, use the Tab key to light up the OK button and hit enter. If you do not do this within 20 seconds, the startup process will continue without loading your persistent Knoppix settings and information. Please see Figure 2, below.

Please note in Figure 2, below, that only three of the four options are checked. Normally that is the way you want those selections to be when you are booting the persistent Knoppix setup. As far we know, you only want to check the overwrite option when you boot your persistent Knoppix into a different computer.

We have not been able to find any good documentation about the overwrite option nor have we found any good explanations of how the overwrite option works and what it does in any of the books we checked. None of the Knoppix experts we have asked have been able to provide any details either.

That said, it appears that you need to check the overwrite option in order to have Knoppix scan the hardware and other machine-specific settings whenever you change the computer on which you are running your persistent Knoppix. Unfortunately, the overwrite option also seems to erase its memory of things such as recent documents too.

The good news is that if you simply reboot a computer once you have used the overwrite option, you do not have to use the overwrite option again if you have not used your persistent Knoppix on another computer in the meantime.

Conclusion

Knoppix is a nice desktop Linux. Because Knoppix is a live CD/DVD it is ready to go right out of the box. That makes Live Knoppix an even nicer desktop Linux. And the Knoppix cheats make Live Knoppix even nicer yet.

For all intents and purposes, the Knoppix live CD/DVD eliminates installation and eliminates going through the installation dialogs. The Knoppix live CD and live DVD are pretty much load and go operations. If a person can turn on a personal computer and drop a disc into the CD drive, that person can run and use Live Knoppix Linux.

Nevertheless, for Live Knoppix as with most computer systems there usually are tweaks, tricks, and things that you can do to improve performance and make things work smoother and better.

The Knoppix cheats let you make such tweaks and do such other tricks and things at boot time, even though you are loading Knoppix from a read-only CD or DVD.

In this series of Knoppix cheat code articles, we looked at the basics of using Knoppix cheat codes in general. And we specifically looked at some performance cheat codes and a cheat code to force Knoppix to use the ALSA sound drivers instead of the default OSS sound drivers.

Today, we also looked at making Knoppix very portable by using the persistent Knoppix trick.

The Knoppix live CD or live DVD together with a USB Key and the persistent Knoppix trick pretty much give you a portable computer on a disc and USB key. Considering that you can download the Knoppix live CD or live DVD at no cost, the only thing your Knoppix portable computer costs you is the price you pay for your USB key -- and that can be as little as $25.

The 4-GB Kingston DataTraveler Elite Flash drive (USB key) that we used for today's tutorials has an MSRP of $399. Some vendors sell the 4-GB Kingston DataTraveler Elite Flash drive for around $300. (Link in Resources section at the end of this article.)

However, you can buy Kingston Flash drives (USB keys) for as little as $25 MSRP for a 256-MB DataTraveler I (DTI/256). There is a 128-MB model for $19 MSRP -- but the extra 128-MB in the 256-MB model is more than worth the extra $6.

In the DataTraveler Elite line of Kingston Flash drives (USB keys) you have a choice of:

  • 256-MB (KUSBDTE/256) at $43.00 MSRP,
  • 512-MB (KUSBDTE/512) at $68.00 MSRP,
  • 1-GB (KUSBDTE/1GB) at $124.00 MSRP,
  • 2-GB (KUSBDTE/2GB) at $213.00 MSRP, and of course
  • 4-GB (KUSBDTE/4GB) at $399 MSRP.

If you have not already done so, give the Knoppix live Linux CD or live Linux DVD a spin around the block. We did and we liked it enough to do several stories about Knoppix and have added Knoppix to the Linux distributions we cover. And while you are at it, you might as well give the performance cheats and persistent Knoppix tricks discussed here today a try too.
