Hi,

I'm planning on installing Gentoo on an old laptop, it's currently running gentoo with lxde but it seems it's too much for it as it can't really open firefox or youtube to well.

I was think if i set it up more minimal than that it might be just good enough.

We are talking about something like this:
1 GB RAM
Intel Atom 1.2

What do you think is the optimal minimal gentoo setup i should use? main purpose is internet and programming.
I'm not really familiar with all the software options but here is what i was thinking:
Gentoo
OpenBox
Midori
Pidgin
Skype
Geany

Troopo,

I have something like that that runs Gentoo. Its an Acer Aspire One, with 1.5G RAM and the original 1.2G 32 bit Intel Atom CPU.
Its the model with the 8G SSD, originally suppliehd with Linpus Linux. When I bought it, the shop tried to sell we a Windows anti virus package, so I agreed but only if they would install it :) They were being very pushy. Anyway while that's entertaining, is not really relevant.

The atom builds for itself but I really need to set up cross distcc for it. After 18 months, it takes just over a week of 24/7 building to update.
Due to the 8G of SSD, it builds on a USB HDD and I wove the useful part of the binary image over after. That needs about 6G.

It runs Xfce4, which replaced Gnome2. Gnome2 was getting abit heavy towards the end and I moved all the desktops I look after to Xfce4 rather than Gnome3 as Gnome made some questinable technical and user interface decisions.

Firefox is still installed but will be removed in favour of Palemoon at the next update. Firefox has lost its way, helping itself to binary blobs without asking.
I've been testing palemoon for the past few weeks. I also have Libre Office installed but I only use it if I'm desparate.

I don't use skype or Pidgin
Quassel Client works well for IRC. My Quassel server is in a datacentre.

Midori is a bit functionally limited for me but if it supports the functionality you need, its a better choice that Palemoon.

Geany I don't know at all.

I have an atom n270 1.6ghz, I upped the ram to two gigs and I run Gentoo with kde (just the bits I want, not meta) and it's absolutely fine. It's not fast but with the exception of hi-def video (and obviously games) everything including firefox runs ok.

Compiling takes ages, ccache helps a bit though.

mrbassie,

ccache, slows down first time compiles as the cache needs to be written.
It may speed up second and subsequent builds of the same package.

It also introduces hard to find bugs.

ccache may be good for package developers, who rebuild the same package many times but its more trouble than its worth for most users.

I use distcc for my Atom boxes, only preprocessing is done locally. More powerful remote nodes do the compiling.

Buffoon,

Why do you not use pump mode?

I thought Atom has the power to do the preprocessing. Am I wrong? (Wouldn't be the first time.)

Buffoon,

With distcc, the client does the unpack, link and install.
It can offload some of the preprocessing and the compile.
Offloading is a good thing but it has the compression, netwerk transmission overhead and the reverse for the results.

I've not timed it as I let my Atom do everything since I don't update it very often.

Troopo, start with replacing firefox. It's the biggest piece of bloatware in this set you mention.
My Pentium III with 256MB RAM worked fine until xorg abandoned drivers for gpu it came with (i810 I think, i915 didn't really do the trick), and flash started to require SSE2.
It was enough for LXDE, Midori usually got the web browsing job done. It's definitelly worth a shot, even though a few websites freak out in it. Looked like JS-related.
I didn't use it for compiling at all though. Just chrooted into NFS-mounted root on a AMD64 quad-core box instead, effectively "borrowing" it's CPU, RAM, and /usr/portage, while retaining the full, 32 bit toolchain.
BTW, LXDE is built on top of OpenBox. I don't know how much overhead it introduces, it was light enough for me.

I know but I do a bit of rebuilding as I like to tinker. Didn't think to mention that when I posted.

In any case I'm not sure if your atom has hyperthreading but mine does (I'm guessing same chip, different frequency. Mine is also in an aspire one [D250]) so with MAKEOPTS="-j3" it's not all that bad. Takes about nine hours to build firefox for example. To me it's tolerable.

With my atom 1.6 netbook I use pump mode (distcc), it's so much faster and much better than the netbook feeling like it's overheating.
Depending on the package the preprocessing is done either on the netbook or the desktop, also it will sometimes decide to compile locally. When something does completely fail to compile, just do a non-pump emerge.

Hi Guys,

Thanks for the replies i really got a lot of good stuff from your comments, i guess i've got quite a few things to try out ;)

Will defeantly compare
LXDE & openbox (maybe xfce too)
Midori & palemoon
local emerge and distcc (even tho locally it doesn't take more than 12 hours at most)

Quassel is a nice touch but running my own irc server can get a bit annoying (i like my conversation private).
pidgin is useful since it can connect to gtalk and other protocols if needed that way i can get in touch with a few people on various old networks.
skype is just a must since it's the most popular voip method and even if replace it at voip some people just use skype as chat and i can't talk to them otherwise.

I mostly prefer gtalk\whatsup for chatting and skype for gaming rooms otherwise i don't have any accounts anywhere else including social media.
