Few days ago, I have sent this test report:
It has been agreed to re-do the same test using different approaches so
there you go:
*Differences from the previous test report (
1. HDD1: Seagate IDE 80GB has been disconnected - Power Cable
disconnected and Data Cable Disconencted.
2. HDD2: Samsung IDE 20GB is the the only working HDD and has been set
to Master (was previously Slave).
3. Installation Type: http://i40.tinypic.com/14jx9h4.jpg
Please note that, there are two different options when installing Lubuntu:
- If Hard Disk is empty and there is no partitions at all:
- If Hard Disk is NOT empty: http://i40.tinypic.com/2iazx2v.jpg
In my test, I have first wiped the Hard Disk Drive (HDD) before starting to
*If you are interested how I did that?*
1. From "Try Lubuntu Without Installation, I used GParted to wipe the
HDD - Create New Partition Table - after I set swap to off because GParted
will not allow you to create new partition table while one of the
partitions is mounted.
2. Rebooted the machine and choose "Install Lubuntu".
- Test for: saucy-desktop-i386.iso
- Daily build: 17-June-2013
- Media: LiveCD
- Burned: using Xfburn at 10x Speed
- Tested on: Real Hardware
*Machine Hardware Details:*
- Desktop Computer
- Intel Motherboard
- CPU: Hyper Threading 64-bit Intel Pentium 4 @3.06GHz
- Cache: L1: 16KB - L2: 1MB
- RAM: DIMM DDR 200 MHz 512MB
- Graphics: Radeon Xpress 200 Host Bridge (built-in)
- HDD: Samsung IDE 20GB - *Wiped and has no partitons at all*
- CD/DVD Drive
- *From BIOS*: http://i44.tinypic.com/a4ug5s.jpg
*Test Case 242MB RAM*
- RAM used by the OS: 242MB only -- Onboard Video Memroy Size = 256MB [
- HDD: Samsung 20GB IDE wiped with no partitions at all
- Installation Media: LiveCD
- LiveCD Booting Menu: Selecting 'Install Lubuntu' From the LiveCD Boot
- Installation Type: Erase Disk and Install Lubuntu.
- Installation Period (time): From Selecting 'Install Lubuntu' from the
Boot Menu until the last reboot at the end of the installation process, the
time period of this installation was *43* minutes.
- The installation Process was *'very slow' *at the 7 steps of
installation (9-10 mins), specially Installation Type Step, Where Are You
Step, Who Are You Step (5 mins only on this step).
- On the very same machine, I have done these tests (
using 'Something Else' installation Type and the installer was much faster
on the 7 steps that required a human actions.
- Despite the great slowness as described above, the installer never
crashed during any step whatsoever - this is a one try test.
- The installation has been done successfully - *100% PASS*
- Time Rating: *LONG* - *40 - 45 minutes* from the very beginning
(booting, menu, etc) to the very end (taking the LiveCD out and reboot).
- Slowness Rating: *SLOW -VERT SLOW* - Something Else approach as per my
Test Report 2 is Faster than 'Erase Disk and Install Lubuntu' approach on
this test report.
- zRAM Rating: *100% Helpful* - it was a very wise decision to add it.
zRAM has made a great noticeable difference. In this very test, if zRAM
wasn't enabled by default, 100% this test would have failed and crashed.
- Overall Rating for this experience/test is *5/10*.
- *I do recommend to set the limit of 256MB RAM as the Minimum RAM required
to install Lubuntu 13.10 From the Desktop ISO using a LiveCD.*
- My Test is done on 242MB RAM, not 256MB and IMHO, the 14MB difference
could make a bit of improvement to the time (less than 40mins) but I *do
NOT* recommend to set the Minimum RAM required to install Lubuntu 13.10
to anything below 256MB. That should be the Red Line.
- 256MB is NOT going to be the recommended option for New Users, but
rather the Minimum. IMHO, we should mention clearly:
1. *Minimum* RAM required to install Lubuntu 13.10 is 256MB
2. *Recommended* RAM required to install Lubuntu 13.10 is 384MB - I will
explain later why :)
1. Lubuntu 13.10 can be installed 'successfully' on 256MB of RAM *(and a
bit below but we are NOT going below 256MB)* from LiveCD without
problems, without crashes, etc.
2. 'Something Else' is FASTER than 'Erase Disk and Install Lubuntu' -
3. *The Minimum *RAM Required to Install Lubuntu 13.10 from a LiveCD is
4. *The Recommended* RAM to install Lubuntu 13.10 from a LiveCD is 384MB.
5. Adding zRAM was very very very helpful and it was a very wise
6. Test done according to the agreed standards that Lubuntu Team has
discussed and agreed on which are described here:
