[linrad] Re: Knoppix 3.8.1 CD with svgalib-1.9.21 and linrad-01.33
Congratulations! You have made a very useful work. I have been reading
your text file and it is marvellous. And you have made a very good
instructions to build something similar.
Only some minor issues:
The text file is very difficult to read cause line lengths are not
equal. Some lines are very very long and I have to scroll the screen to
the left to see the end.
It would be desirable to create a real *.deb package for svgalib and for
linrad instead of installing on the /usr/local. But while we have that,
it is very fine like it is.
I can not test your CD now cause my internet connection is very slow at
home(it is a holiday day here today), but perhaps during the week I can
download it at the University were we have faster Internet connnection.
Sufferring from linux withdrawal after getting Debian to run on 3
machines here I decided to make a Knoppix CD with svgalib-1.9.21 and
linrad-01.33 on it, configured so that [if all is well] linrad would
come up running before one even got to the Knoppix attempt to start
XWindows [which you can prevent by typing 'knoppix 2' at the boot prompt].
I did this because I have been impressed that Knoppix 3.8.1 [with the
2.6.22 core] has the best hardware detection algorithms of any of the
distros short of Fedora that I've tried, and because there seems to be
this aversion to Fedora hanging in the air.
I had tried Morphix, but its hardware detection was NOT even close to
Knoppix, and by virtue of its small size it just didn't cut it, as if
it didn't work 'out of the box', the tools I wanted to fix it weren't
in the package. So if the network was being balky about starting, one
I added a bit of things I wanted to the standard Knoppix distro [Opera,
svgalib-1.9.21 and linrad-01.33 and a few other things], and removed
OpenOffice so that it would all fit on a CD; the KNOPPIX.iso file is
682.302 MB. I have tried it on 5 computers and XWindows video works on
all of them. By changing /libvga.config to use the VESA driver,
svgalib video works on all of them.
The computers range from an old 900MHz P3 and an old AMD P1800 [both of
which have bioses pre2001; 2000 and 1997, respectively] to a newer but
still not new 1G P3 to an old AMD 2100 thereabouts, to a Dell 1.8 GHz
P4. The video hardware ranges from old Radeon to newest Radeon to old
onboard to newer onboard. The sound is either onboard or Creative Labs
[only one card or onboard unit in each machine]. I am not more
specific about all of this hardware as its been a long time since I
assembled these specimens, I didn't take any of the computers apart
today to check, and they are mostly not mine, but belong to each of one
of us 5 in the nuclear family here, and I shoehorned my experiments in
on less than enthusiastic participants, so my data collection time was
I got XWindows sound out of 3 of the 5. One of the other two hasn't
had any sound for a long time, and the other may have had sound
available, but it didn't have speakers attached and I didn't have time
to attach them ;)
With 4 of the 5 machines linrad worked in some fashion, but it was
perfect with sound in only 1. In two others I got the appropriate
waveforms on the screen in all display windows, but nothing out of the
speakers. In one other I didn't have time to get any sound to
display; I think I ran thru all of the "U" configuration possibilities
with no sucess. The 5 one was an XP P4 with USB mouse and not
surprisingly that locked up. I didn't have time to play with it AT ALL
as my son was in the midst of wargames. Time spent on each machine
with the CD was less than 15 minutes, probably closer to 5 minutes in
I would be interested in some people trying the CD to see how it works
for them. I would also be interested in having it critiqued my some of
the Linux gurus on the list to see how it can be improved. I DO NOT
think we should try to pare it down in size, except to get rid of the
unnecessary configuration files, etc. that are probably on it.
I removed the XF86Config files as that is essential Knoppix is going to
go thru its hardware detection routines, but I don't know if there are
other similar files for audio or other subsystems that I should have
also removed, but didn't.
A brief note of what I did is at
I haven't formatted it and put it on a webpage yet, so it will be
easier to read if you download it into a wordprocessor where you can
set some margins.
I didn't make it up to Hilltop to try this on the real Linrad systems yet.
I did use Linrad some on the microwaves this weekend and was again most
impressed by the utility of being able to see +/- 45 KHz on the higher
Let me know if you are interested in the KNOPPIX.iso file, and if you
have any ideas about how/where it could be made available on the web.
I can upload it anywhere, but it will take 682.3 MB of space once it
arrives, and comcast doesn't give me that much ;)
