Advice: will this CPU run Lubuntu 20.04?

I’ve got an old Toshiba Satellite Pro A100 (I believe) that I’m wondering if I can install the new Lubuntu on. The CPU info follows. I’m sorry — I can’t work out it if it is 64-bit capable, of whether I need to install a 32-bit OS on it. Thanks for any help with this!

It needs the lm flag to do 64 bit.

Hmm… I assume this is a “no”, then - it won’t run latest Lubuntu. :slightly_frowning_face: Which is a wee shame!

Thanks for the quick reply, all the same. Much appreciated!

Right. It’s a no. I would suggest you consider looking at Debian as an alternative.


Try Lubuntu 18.04.5 32 bits version.
Your CPU have power enough to browse, videoplayback and others softwares.

Even then you may not get a great experience anyway. It’ll run for sure, but maybe task you want to do on it may be limited.

I tested Lubuntu 18.04.5 LTS on a

hp d220mt (dr159p), (celeron 2ghz, 1gb, 82845G/GL Brookdale-G/GE (i915))

and mine reports itself as Pentium 4 family (not Pentium III) in lscpu, and yet the performance of mine was less than pentium M laptops and pentium 4 desktop I also test with.

Yes Lubuntu 18.04.5 was perfectly usable, but I also stream a youtube video in testing, and here the hp d220 celeron kept pausing, where my pentium M & pentium 4 laptops/desktops do not. There are a number of things (like streaming vids I’d not want to use it for). Celeron’s have higher clock speed (2GHz used for marketing is faster than any pentium M I use), but less where it really matters.

It may also be i586 class, where i686 class of cpu is required for Lubuntu 18.04
