Hi,<br><div><br></div><div> Ali, firstly thank you for all the work you put in for the minimal specs of what lubuntu will install on. To everyone else working on this, also a big thank you.</div><div><br></div><div>For our minimal specs, once we get to 256MB RAM, we are also stretching the applications (browser).</div> <div><br></div><div>@ Jluien, if Z-Ram works so well, could we drop alternate for some of the archs? </div><div><br></div><div>Regards,</div><div><br></div><div>Phill.</div><div><br></div><div><br><div class="gmail_quote"> On 17 June 2013 00:45, Ali Linx (amjjawad) <span dir="ltr"><<a href="mailto:amjjawad@gmail.com" target="_blank">amjjawad@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div dir="ltr">Hi everyone,<div><br></div><div><b><u>My Test - Part 1</u></b></div><div>*Note* These Tests have been done on Oracle VM version 4.2.12 running on Windows 7 on HP Pavilion DV6, Core i5 first generation and 4GB RAM. </div> <div><br></div><div><b><u>Test Case A</u></b></div><div><br></div><div><u>Hardware Details:<br></u></div><div>CPU: 1 CPU<br></div><div>RAM Used by the OS: 256MB</div><div>HDD: 5GB<br></div><div><br></div> <div><u>Scenario: </u></div><div>This is to simulate when the user has 256MB Physical RAM and a dedicated Graphics Card that does not steal/share its memory with the RAM.

IMHO :)</div> <div><br></div><div>My above 4 test cases were about the minimum system requirement to 'install' Lubuntu.</div><div>After all, the usage of the system purely depends on the user. If he is a light user, the system won't be so demanding at all.</div> <div>If he is a heavy user, that is totally different story.</div><div><br></div><div>So, IMHO, we should be clear about this point.</div><div><br></div><div><br></div><div><b><u>Recommendation:</u></b></div> <div>Long story short, I do recommend that:</div><div><b>The Minimum System Requirement to Install Lubuntu 13.10 from The LiveCD using the Desktop ISO, is ... <u>256MB</u> Physical RAM.</b></div><div><br> </div><div><br></div><div><b><u>Next Step:</u></b></div><div>I have moved houses so all my stuff are packed. I need to take my old test PC from the store, find my keyboard and try to play with it and repeat the above tests (not all of them).</div> <div>What so special about that PC is:</div><div>It has 512MB Physical RAM and its BIOS has a feature to share 32MB-256MB for the built in video card. So, I can test down to 256MB RAM.</div><div>I can not go below that. But, after all, from what I've found so far, it is useless to go below that as long as the above recommendation says it all :)</div> <div><br></div><div>Thanks for reading my report!</div><div><br></div><div>End of report.</div><span class="HOEnZb"><font color="#888888"><div><br></div>-- <br><div dir="ltr"><div><p style="margin:0px 0px 1em;font-family:'Ubuntu Beta',UbuntuBeta,Ubuntu,'Bitstream Vera Sans','DejaVu Sans',Tahoma,sans-serif;line-height:19px"> <span style><font color="#000000"><big>"All of us are smarter than any one of us."</big><span></span><span></span></font></span></p><p style="margin:0px 0px 1em;font-family:'Ubuntu Beta',UbuntuBeta,Ubuntu,'Bitstream Vera Sans','DejaVu Sans',Tahoma,sans-serif;line-height:19px"> </p></div><div><b style="font-family:'trebuchet ms',sans-serif"><span style="color:rgb(11,83,148)">Best Regards,</span></b><br></div><div><span style="font-family:'trebuchet ms',sans-serif"><b><span style="color:rgb(11,83,148)"><a href="https://wiki.ubuntu.com/amjjawad/" target="_blank">amjjawad</a></span></b><br> </span></div><span style="font-family:'trebuchet ms',sans-serif"><b><a href="https://wiki.ubuntu.com/Lubuntu/CommunicationsTeam/WOWLubuntu/StartUbuntu" target="_blank"><span style="color:rgb(204,0,0)">Start Ubuntu</span></a></b><br> </span><div><span style="font-family:'trebuchet ms',sans-serif"><br></span></div><div><i><span style="font-family:'trebuchet ms',sans-serif">Test Machine: ASUS F3F Laptop - </span></i><span style="font-family:arial,helvetica,sans-serif"><span><i>Intel Core Duo T2350 @ 1.86GHz with 489MB RAM</i><br> </span></span></div><div><br></div></div> </font></span></div></div> <br>--<br> Mailing list: <a href="https://launchpad.net/~lubuntu-wiki-docs" target="_blank">https://launchpad.net/~lubuntu-wiki-docs</a><br> Post to : <a href="mailto:lubuntu-wiki-docs@lists.launchpad.net">lubuntu-wiki-docs@lists.launchpad.net</a><br> Unsubscribe : <a href="https://launchpad.net/~lubuntu-wiki-docs" target="_blank">https://launchpad.net/~lubuntu-wiki-docs</a><br> More help : <a href="https://help.launchpad.net/ListHelp" target="_blank">https://help.launchpad.net/ListHelp</a><br> <br></blockquote></div><br><br clear="all"><div><br></div>-- <br><a href="https://wiki.ubuntu.com/phillw" target="_blank">https://wiki.ubuntu.com/phillw</a> </div>
