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 -------- Original Message -------- Subject: memory needed for Lubuntu tested with vbox Date: Sun, 14 Apr 2013 20:12:18 +0200 From: Nio Wiklund <nio.wikl...@gmail.com> To: ubuntu-qual...@lists.ubuntu.com <ubuntu-qual...@lists.ubuntu.com>, Lubuntu-users@lists.ubuntu.com 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 Nio alias sudodus ---------------------------------- On 2013-06-17 02:06, Phill Whiteside wrote: > Hi, > > Ali, firstly thank you for all the work you put in for the minimal > specs of what lubuntu will install on.
