thanks puppy_apprentice, As far as I am aware the boards have double the mentioned ram only the early boards have the lower amount - we can run without much ram - by todays standards. The review conclusions are correct - it is a marvel, the software - a Puppy speciality is getting the most from limited resources will be key OK gonna go see what apt-spy is doing . . . Sardines on a plate [Lobsterian cussing] . . . it crashed

pretty much most linux distros are multi user, its puppy that is the odd one out being a single user OS, seriously if you try stripping out the multi user things from debian it will cause alot more trouble than having to sudo -i or su root |

Size of external SD card that you installed http://downloads.raspberrypi.org/images/debian/6/debian6-13-04-2012/debian6-13-04-2012.zip to? I haven't gone through the whole thread to see what you are using lobster . I get by using a 8 gig SD card (preferably class 10 if possible) with a AntiX Full iso install. 690MB cd and after install with nothing added it comes in at a little over 2gig space taken up on SD card.
Inserting my nose, even though I don't have a raspberry pi board. For no X11 folder in /etc. You need to install xorg. I installed LXDE on this core install
this Laptop uses Hot swap drives. I run LightHouse 5.03 32 bit on here also. in case you want to install the inxi information script in your raspberry pi's In terminal as root
let it download and install. Then just run inxi -F to get system info on your raspberry pi's. You saw how in inxi -r I was able to show my repos I won't get into installing smxi or sgfxi into raspberry debian as it is a little more involved and can break stuff if not knowing how to run it, and inxi is just a info script. So it is harmless to install http://code.google.com/p/inxi/ I better back my nose out of here before I get into trouble.  [/quote]

if you are running the Rasp Pi debian image that can be downloaded from the Rasp Pi site, then everything should be configured to go right ahead and run apt-get update then apt-get install jwm what is in your /etc/apt/sources.list file? you cant just download and install debian arm from the debian and get a working iso like you can with the other i386 or amd64 type platforms, the packages all exist in a repository and you have to use an already working debian to download the packages and use debootstrap etc to chroot and do other things that i dont particularly know how to do.... im mentioning this above about the debootstrap method because to actually make the OS you have to have had the correct repo information already entered in your /etc/apt/sources.list file to begin with. but if you are running the debian image from rasp pi people and the apt-getting isnt working after you apt-get update and you know the network stuff is working, then post the contents of the /etc/apt/sources.list and we will help best we can |

I like being single user. In fact once a release version of Raspberry PupPy or whatever it is called, is released . . . the first thing I will do is push down the lock on the SD card and save on a USB keydrive However Sickgut you are more knowledgeable on potential problems/implementations. Appreciate your advice. I was hoping to use sound - but the ALSA drivers not yet available. _________________ Puppy WIKI |

re: lobster running out of space... is there a difference between the size of the image being used and the size of the SD card? What i mean is if you have say a 4gb card and your using a 2gb image, it could be that the entire card isnt being used, and if thats the case then its easiest to apt-get install gparted or some other partitioning software that will let you resize partitions so you can gain access to the rest of the card.... i dont have a rasp pi yet and i havent used their debian image in an emulator but i have had alot of experience with imaging one image that is smaller than the card to a larger card .... unless they are using a special installer that automatically fills in the unused space after the card is prepared imaged etc then you will have to assign the extra space yourself also, are their swap partitions and or a swap file presetup on the card if you use their image? |

Keep the snoz in 
You and the other people here are the nearest thing we have to an ARM development team
I appreciate all the suggestions and help I can get.
At the moment I am starting again . . . putting Squeeze on a couple of four Gig cards. _________________ Puppy WIKI |

Problem with running a debian image that is multiuser and trying to do everything single user is that yeah you can just log in as root and do everything as root, but when you install programs from the debian repos, they often expect a normal user to execute them not a root user, one example of this is VLC as it simply refuses to run as anything other than a normal user. And the problem with running as a normal user, after you have installed as much stuff as you can as root is that you boot into your X session and click on things and nothing works as you dont have permissions.... so you end up with having to log in as root to run half your stuff and as a normal user to run the other half. This is the problem with sticking with the base default debian image, once you puppy is compiled for it then ofc you can do whatever you like with users, but its basicly impossible to bleach out the multiuser stuff in the debian image that was built ground up to be multiuser. I think it would actually be quicker and easier to build a puppy from scratch than convert debian to single userness and have it work like puppy does. really? alsa drivers in the default image? wtf... do they have any other sound drivers installed or is the Rasp Pi simply mute at the current stage? If its a case of yes the drivers are in there but its not working then there is a line that saintless contributed to the pussy project that redetects the sound stuff once you are booted and this generally got non working sound hardware to come to life but it uses alsa tho, if alsa drivers arent there then it wont work..... ill see if i can find the line of code to run, i dont have it with me atm, ill update this post when i get it together.... it may or may not help, i dunno also... if there is no sound drivers for the Rasp Pi, i wonder if you can run a external usb sound adaptor and use that instead? does anyone know anymore about this? |

unfortunately the very few people who actually know about debian ARM are the same ones who actually contribute to it and funny enough are way to busy to answer questions and help end users... getting support for debian ARM is like accidently breaking your ARMs and your legs and rolling to the hospital.... you will prob die of old age before there is any help available.... i think once the rasp pi is in the hands of more people and the forums are alive with actual useful info about the debian image they use, things will get easier. hmmm.... ill see if i can get one of these rasp emulators etc and help out. can someone give me a link please? i have had pleanty of experience with the normal debian on intel hardware and most things are the same but there could very well be many many things i am over looking in relation to the Rasp Pi image and it running on ARM etc.. maybe a day or two messing with the emulator will help |

Lobster I guess an external USB type sound card would work but surely it would also require drivers. Since Pi has no sound support yet, this is the perfect excuse to reach for the soldering iron and build an external R-2R type DAC to get some elementary 8 bit sound out of the GPIOs Remember the Mod scene from days gone by? I remember building a crude DAC for the LPT port on an old 386 PC then writing software to send out samples from wav files one by one to the LPT port where the DAC would convert the samples into analog voltages. Filtering was very basic and consisted of a few capacitors and resistors. No awards for "hi-fi" sound, but it worked suprisingly well given it's simplicity. The output from the DAC can be connected to a pair of amplified PC speakers thus saving the hassle of needing to build a small audio amp. Since the Pi comes with gcc, then I assume it also has "usleep" which one can use for a delay and timing between samples. Once I get my Pi, whether sound support is available by then or not, I'm gonna build myself one of these just for the fun of it. The pin-outs of the Pi here: (The pins of interest are GPIO 0 - 7 and of course 0v) http://elinux.org/RPi_Low-level_peripherals |

Ok. You asked. Here goes nothing. Remember I am a tattooed GED educated Self taught Linux User. I remembered this fix after a power nap thinking about you ran out of room installing JWM. If you get an error like:
When you tried to install JWM . This has nothing to do with size of SD card The fix is to edit as root your /etc/apt/apt.conf file and increase the value of the APT::Cache-Limit line to 75000000, save that file and then re-run the command. Also. Always run
before installing anything through apt so you get the latest libs and applications available When done installing everything after updating. To clean the sd to free up space as root again
run df-h after apt-get update. Put it in a text file. Don't have to save it. Then do df -h again after apt-get clean. You'll notice the difference.
10MB aint much but it may make a difference later. My system is pretty up to date though since I run as a rolling release schedule. You might download more than 10MB. I'm off to install a 3.3.1 kernel next. Since I am a AntiX team member. As well as a MacPup team member for runtt21 (I have been a little busy to mess like I would like with Macpup528v2 Beta) but I get there eventually. |
