Re: Minimum and recommended RAM to install Lubuntu Trusty

Hi Phill and Julien,

Hi all,

Here are my test results concerning minimum and recommended RAM to
install Lubuntu Trusty

Testing with the boot option 'mem' in the following computer


('effective' is what is reported by 'free -m' as total memory)

Erase disk and install (with swap partition on the HDD)

Lubuntu Trusty desktop 32-bit beta2
mem=256M (effective 241M) OK
mem=224M (effective 210M) heavy swapping to zram and disk, but OK
mem=192M failure

Erase disk and install (without swap partition on the HDD)

Lubuntu Trusty desktop 32-bit beta2
mem=256M (effective 241M) OK
mem=224M (effective 210M) heavy swapping to zram, but OK
mem=192M failure

lubuntu Trusty alternate 32-bit beta2
mem=192M (effective 178M) OK
mem=176M (effective 162M) OK
mem=160M failure


Absolute minimun RAM for the standard installers

Lubuntu Trusty desktop 32-bit: 224 MB
Lubuntu Trusty alternate 32-bit: 176 MB

More memory is necessary for more advanced install alternatives, for
example dual boot using 'Something else' at the partitioning window.

Recommended minimum RAM for the standard installers

Lubuntu Trusty desktop 32-bit: 384 MB
Lubuntu Trusty alternate 32-bit: 256 MB


The One Button Installer can install systems with 128 MB RAM.


The 9w installer can install systems with 80 MB RAM, but Lubuntu Core
Trusty needs 128 MB RAM to run and at least 256 MB RAM to be really useful.


Computers with less memory can be used in text mode (or maybe in
graphics mode with some other really small linux distro).

See posts #88, 89 and the following posts in this thread about 9w.


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!

Best regards

Thank you!

Hi Phill,

Yes I can. I'll test with standard Lubuntu 32-bit.

I guess the priority list should be what is possible with the

1. desktop installer

2. alternate installer

and the non-conventional alternatives can be tested with standard
Lubuntu and or Lubuntu Core

3. OBI (only booted from mass storage devices, typically USB pendrive)

4. 9w (booted from CD/DVD/USB drives)


I was not able to install Lubuntu Saucy with 128 MB RAM and any of the
conventional installers. The alternate or mini iso (netboot) installer
needed at least 160 MB. I could install with the OBI with 128 MB. I did
not try the OBI with less RAM. The text in that page is brief, and I
think it should state the limit for each installer. I expect that the
limits will be the same or slightly higher with Trusty.

Best regards

     Hi again!

     A couple of friends at the Ubuntu Forums have helped us find the low
     limit of hardware, when Lubuntu Saucy and Trusty can run (as installed
     with the 9w installer)

     See this link (posts #76-79)
