I just used a Live CD for the first time today, in part to show what CentOS can do for a co-worker who is looking at using it at work and home, but I got the strangest result. We booted the CD and let the centos user log in. It took a really long time to load the desktop and there were no panels, so the only things we could do were browse the computer, CD, home, file system, keyboard (sort of) and pretty much nothing else. <alt><f2> and <alt><f1> did nothing, either - no menu, no input windows - nada. Is that normal? If not, what did I/we overlook? I was expecting a lot more, and from looking around the wiki, there should have been, but I couldn't find a good reference for what the Live CD is supposed to be able to do or let a user do. Thanks. mhr

It sounds like there are hardware issues with the machine involved and the livecd booted. -------------- next part -------------- A non-text attachment was scrubbed...

(cd-r, cd+r, cd-rw, cd+rw ...) Or maybe it is just the skew of the burn is outside of that readers acceptable range. -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

I burned it at 40x (it's a 48x TDK CD) using K3B with write verification, so it passed the md5sum after the write completed. I suppose it could be an incompatibility between my burner (a Pioneer 18xXxXx DVD burner) and the reader (a TEAC CD-540E). I noticed that the target system, which normally runs (well, actually, walks is more like it) Ubuntu 8, only has 256MB of memory - could that be part of it? The other oddball thing was that, after we had booted the LiveCD and given up on it, we had to reboot the Ubuntu in repair mode to get it back up (!!!). I haven't tried it anywhere else just yet.... mhr

You were very lucky the demo was for a colleague and not for your Manager or his/her boss! Test what you do, as much as is possible, so others do not catch your mistakes! TYS... There are reasons for V&V (Verification and Validation), Design Walk Through, etc. The earlier mistakes are found, the easier it is to fix them. I have a Live CD for an earlier version of CentOS and we have one old box (Firewall/Router backup) it will not run on. I believe that's because of a video problem. The Live CD's have a number of uses, which include: (a) Being able to Rescue a box that has bad problems. They usually have many utilities on them (b) That one can see if the regular Installation will fly on the HW, before actually trying to install. (c) You can take a Live CD with you to a store, if you are contemplating buying a box, and see if Linux will run on it (d) I plan to take a Knoppix Live CD with me, when I travel, so if I need to use a Public box, I can boot Knoppix, do whatever I need to do, and not leave a footprint. The Knoppix Live CD has been recommended here on this ML and is very popular. In your case, the CentOS Live CD was a better choice, since your colleague is interested in using CentOS (a great idea). Seems like you have a TEAC burner. Someone here on this list, last year, told me that he does not like them. I personally will not buy any more TEAC drives, because recently, I learned they did not have Diagnostics for my CD-RW drive. It went into the trash. Drives that we have had good luck with include: Samsung, SONY & LG. Other's probably work just as well. We have other TEAC drives, but they are the last TEAC drives we will purchase. The CD-R media I usually buy are Imation or Verbatim. Never had a problem. There are probably other brands equally good. When I burned the Knoppix Live CDs, K3B burned them at a high speed as I recall, but, as has been suggested in prior responses, throttling back on the speed probably greatly increases the chance of getting a good burn. K3B checks the MD5 sum, as I recall, when it begins the process. HTH, Lanny
