Distro ISO Download Questions


Compaq 32 bit Laptop
Dell 64 bit Laptop
Unknown 32 bit Desktop

First downloaded ubuntu 10.4 Netbook iso and the Demo ran on the Dell 64But hung with a blank screen on the Compaq
I know I know "Netbook" is not the same as "Notebook"

Could some kind soul elaborate on the variants available for download?
What is Alternate i386? Is it for Laptops?
What is Desktop i386? Will it run on a Laptop?
What is Desktop AMD64? Will it run on an Intel 64bit duo laptop?
Thanks for your help

Hi,

Any x86 will run on 32 bit or equivalent but x86_64 will not run on a 32 bit systems. So to answer your query is that you will need to download a 32 bit distro or i386. You can custom the kernel and applications but it would be a lot easier to be sure to select the proper architecture for the distribution of choice.

Yup thanks
Questions:
What does the "Alternate" distro run on?
What does the "AMD64" distro Run on (AMD or Intel or both)?

There are machines with different CPU architecture, so you need a distro that was compiled for your computer configuration. You may find this one useful http://www.amazon.com/Diversity-Coll...6023870&sr=8-3

Does the set include for different architectures? What about other platforms?

Why pay that much anyway? Just go to DistroWatch and download whatever you need for free.

Sure you will need media but there are ways to install without burning a image.

Doing the Downloads here on LQ
I have downloaded four of the ubuntu 10.4 distros.
Lacking an Info blurb for each of the distros I attacked the problem empiracally
So far I have burned three of the distros and these are my results
Ubuntu 10.4 Netbook works on Dell Laptop Intel 64but duo byt not Compaq presario 32 bit (No Video)
Ubuntu 10.4 Desktop i386 Hangs on the Dell laptop and has no video on the Compaq laptop
Ubuntu 10.4 Desktop AMD64 Works on Dell Laptop Intel 64 Not tried on Compaq Presario

Have not Burned Ubuntu 10.4 Alternate

Does anyone know what platform the Ubuntu Alternat distro is intended for?

I think I'd play with live cd's more. Live cd's tell you pretty much if a distro will work.

As for alternate. One post has this. "This installation CD is suited for computers unable to run the graphical desktop based installation, either because their computer does not meet the minimum requirements for the live cd or because their computer requires configuration after the installation is complete in order to use the desktop." http://www.ubuntu.com/desktop/get-ub...ative-download


Each one may need a distro choice and may have to have some work to get it all working. There is not one stop cd/dvd as of yet. Solaris has both on one cd I think.

Netbook is for those kids play laptops.

Might also have to see distrowatch and try some different choices.

Linux is not all that reliable about selecting a usable video driver on initial boot up of an installer and/or liveCD.

Probably those two CDs would work on the Compaq if you got them to select a usable video driver (or maybe refresh rate or maybe resolution).

For Ubuntu 10.4, I don't know the syntax used during boot to select a video driver (or refresh rate or resolution). But most Ubuntu things are decently documented on their web site, so you ought to be able to find it.

In a large number of cases, the vesa driver works OK when the driver selected automatically doesn't. So that is always my first try when having graphics problems with some specific Linux CD on some specific hardware. Once you have graphics basically working with the vesa driver, it may be worthwhile to figure out how to properly configure some other driver for a better choice of resolutions or refresh rates and/or for faster graphics.

But first you want to get graphics working at all. Usually, you don't need to drop a distribution because it guessed the graphics wrong on first try. Usually you can give it some boot time options to get past that.

ubuntu-10.04-alternate-amd64 is for 64-bit PCs (obviously). The main advantage it allows is /home encryption. Of all the LTS 'buntus out there, this is probably the best one to go with (either amd64 or i386), at present. Others I have spoken with say it runs well on their machines and I have it on one hard drive for my e8400 machine, too.

One may still have to go into Users and Groups and modify the original login, then go to console and
PHP Code:
passwd [username
and set login password for a new user with root privileges, then
PHP Code:
sudo passwd root 
if necessary, however.

This is why I'm disappointed in the new ubuntu LTS.

OK burned the "Alternate" as well. It has no Autorun and is unusable as a Demo version.
Does anyone have any idea what the AMD in Ubuntu1.04AMD64.iso stands for?
You would think AMD64 would indicate AMD vs. Intel but it seems to boot up and run on Intel with no problem.

I think you are right. What would I need to do to get those graphics working? I tried ctrl alt F1 and it was no go.

Hi,

one more thing about the alternate installer is that you also have some additional install options, e.g. encrypt the system. AFAIK, this option is not available with the liveCD. It is possible to encrypt the system with the liveCD though, just takes some additional effort.

The Alternate CD installs the same Ubuntu system as the Live CD. It is intended for users who do not need a demo, who just want to install Ubuntu quickly (with a few extra install options, like encryption).

There is no reason to download/burn the Alternate CD if you already have the Live CD and do not need advanced installation options.

You should start a new thread (with a descriptive title) for your Compaq video problem. At the minimum, you'll need to specify what kind of video card it has; without this information, nobody will be able to help you.

I am assuming you've already read the Ubuntu Hardware Requirements and the computer meets or exceeds the minimum?

It's always nice to know the brand and model of video card and monitor when debugging a graphics problem.

But even without that, someone here ought to know where the Ubuntu 10.4, kernel boot "cheat codes" are documented and/or what keys you press when to enter such codes at the Grub menu (before it times out and picks the default) as well as what codes you enter to force the vesa driver and/or force 60 Hz refresh.

You probably won't get optimal graphics with the vesa driver and 60 Hz refresh. But in the majority of problem cases you get usable graphics. Once you have usable graphics, you are in a much better position to investigate the question of what driver and settings will give you optimal graphics.
