Bug Description
Binary package hint: ubuntu-live
Hi,
On old computers, the live cd installation can fail due to insufficient memory (i.e. less than 500mb). This information isn't provided to user, who are often confronted with an installation which stalls/
Ubuntu live should check the amount of available memory before attempting installation and provide a warning or use the swap file if the memory is too low. Fedora Core and others do this before installation
Thanks,
James

Trying to run Xubuntu 7.10 on an old Gateway Solo 3350 with only 256MB of memory (= max installable) was a pain, with constant "swapping" of data in from the live-cd.
Trying to install was completely impossible, and even the ubiquity-only option would stall before starting (showing the first install screen).
Solution: I followed the recipe given in http:// cutecomputer. wordpress. com/2006/ 07/18/ubuntu- 606-installatio n-on-legacy- pc-low- ram/
Basically, I booted from the live-cd, immediately Ctrl+Alt+F1'ed to the console, created a 1GB swap partition ($ sudo fdisk /dev/sda)($ sudo mkswap /dev/sda1), added the new swap area to the live-cd system ($ sudo swapon /dev/sda1), then Ctrl+Alt+F7'ed back to the desktop and double-clicked the installer icon.
This time it ran like a charm.
So yes, if swap is available, then use it (ask first, to be polite).
Furthermore, since we're talking about somebody wanting to use the installer, and the installer requires the existence of a swap partition anyway, why not run fdisk (or similar) for them if swap does not already exist yet? Especially if there is free space already available on the disk!
Because a really helpful fix will cost time/money, if it is judged that there is not enough real need for a real fix, then at least provide useful info about the lack of memory being a problem, and what to do about it, instead of just spinning the wheels off the cd...
