Thanks for sharing all this but needless to keep repeating myself here
which I must do to make sure everyone is really aware of this:
"It is 'not' about installing Lubuntu on a low RAM machine but rather
how to use the system 'after' you install it" - Ali Linx/amjjawad
I have P2 with 64MB RAM and 4GB HDD and it has Lubuntu 11.10 installed
on - http://ubuntuforums.org/showpost.php?p=11832431&postcount=152
Yet, the best that machine could do is login to the desktop and
sometimes run sudo apt-get update. Beyond that, it will produce smoke
and might burn the house.
Please make sure that you're dealing with totally 'new' people to Linux.
Those who might read these will understand that Lubuntu is a life savior
and their 256MB RAM machine will work like a charm. THIS IS BAD. I'm
serious. You're not dealing with advanced users, you're dealing with all
kind of users from different levels and backgrounds. When you say
'Recommended RAM' that means when you install that system on that
'recommended RAM', your system 'should be' working as expected.
That said, as per my +3 years endless tests, the Recommended RAM for
Lubuntu 'must be' IMHO = 512MB
If you will ever mention 'minimum' then you should mention too that:
"please note that your machine will not work as expected after installing."
Let's be 'extra' clear when we're dealing with our users if we do care
about them. This is 'very' important IMHO.
I hope this is clear. I'm 'still' trying to help you guys as long as I
can. And you need to provide the 'correct' information as always.
To me, it is totally non-sense to even waste time to test that on less
than 256MB RAM simply because your machine will not handle one open tab
say Facebook or Gmail. As for YouTube, you should mention a huge red
label note that those with less than 512MB should forget YouTube and
watching movies.
IMHO, that should be the job of the Wiki and Docs Team to make sure that
the Wiki Pages are 'correct' and 'clear'. Feel free to have a look at
Ubuntu GNOME Wiki Area and don't hesitate to ask me if you need anything
as I'm the creator of that area:
https://wiki.ubuntu.com/UbuntuGNOME/OneStopPage
If you're doing this out of curiosity or for theoretical research, you
shouldn't mention that on the Wiki. Yeah, it is okay IMHO to share it
here but IMHO, it is a mistake to put that on a Wiki Page. This will
confuse the 'new' users that you guys are targeting in regards of
StartUbuntu Project and all.
If you still in doubt, please ask!
