Hi,
With all respect to your skill as a tester, Ali, I have to ask:
1. Has the GUI installer of Saucy improved a lot compared to Raring?
2. Or was I doing something seriously wrong?
Because I could not install Lubuntu Raring 32-bit without swap, not even
with the alternate installer, with 256MB RAM. I did it in VirtualBox in
a Precise 32-bit host.
I'll test it tomorrow in Saucy and switch off the memory hogs in
VirtualBox. I will also try to test low RAM in a real computer :-)
Best regards
Nio

I want to share these results from testing to install and run Lubuntu
with low memory. I was using today's daily build of Lubuntu Raring
desktop and alternate iso files.
See the attached file. Comments are welcome :-)
Best regards
