Some configuration help for Ubuntu on USB as portable OS

Hi all,

This is my first post here so sorry if I make any mistakes. I'm a linux newbie but comfortable with trying things.

I have installed Ubuntu 7 (fiesty fawn) to a 8gb USB with a ext2 partition and a 300mb swap. I want it to be a portable web development OS as I don't always have access to a regular computer. I may use friends or go library etc.

I have 5 configuration questions to help with my setup:

1. Resolution, as I could be using any computer I'd like at least the option to try and run at 1280x1024 as most modern monitors can handle this. Obviously I don't want to install a driver for each machine I use, is there any generic drivers I can use or options? I tried xrandr but on U7 I have no option to add modes?

2. I had Ubuntu 7 on disc, download would have taken days on my internet connection. When I get to a decent connection can I download latest and simply do an upgrade? Will that upset my installed programs apache - php - mysql. What's the best method, I don't want to install everything again it took too long.

3. Repositories, though I'm using an older Ubuntu version can I still use the latest repositories for newer versions? And where am I to find a reliable list of all the best/latest repositories that I can use?

4. I would like to reduce the wear on my memory stick by limiting unnecessary writes in general. What should I be looking at to restrict, for example on Windows I might turn of indexing and such?

5. Finally, I compiled the 8712u.ko realtek driver for my 8188SU Wireless USB dongle as I will be using it wherever I use the OS. Each time I reboot I have to insmod the 8712u.ko file before my dongle works. How do I go about making this permanant so I don't have to do insmod each time I boot?

Thanks for the help

They will send you a new cd for free you know. Don't play with that old distro.

I use flash drives all the time. They fail for all sorts of reasons but I doubt they fail just because of r/w's. They cost nothing so just throw them away in a year. Normal issue is no swap but you may need it. And use the older ext2 to limit but other than that I wouldn't worry about it.

A newer version would help out on drivers but you may have to add in video options.

Someone may know about the driver.

Hi jefro,

Thanks for the reply,

I downloaded the latest version, I can only connect to internet on BT Openzone which constantly cuts out so a http or ftp download wasn't an option without a DL manager. They can't be relied on.

Anyhoo, I went looking for the CD you suggested and noticed the torrents in alternative DL's. Just had to stay up all night re-connecting to damn wifi, oh the challenges of a simple task :-)

You helped answer all my questions. Thank you :-)
