Hi everyone,

So I've found a Thinkpad X200 online and I'm thinking of buying it for libreboot purposes. Do you think the P8600 cpu can handle all the
compiling on gentoo? For the record, I don't have any of the "big stuff"
like KDE, GNOME, Firefox (all I have is Tor Browser [which I don't
compile], dwl and some terminal programs like neomutt and profanity).
Surely, I wouldn't be spending 5 hours to do small upgrades,
right?..right?

Thank you

It's getting harder and harder. There's always GCC, which is going to
take you most of the day to build and will probably require -j1 to keep
you from running out of memory. But aside from that, the big ones are

* dev-lang/rust: pulled in by anything that needs SVG support unless 
you unmask an old insecure version of librsvg or can tolerate half-
broken SVG support. This takes over 24h, requires -j1, and gets
worse every day because it bundles all of its (growing list of) 
dependencies.

* LLVM: needed by rust, some video cards, and certain picky packages.
This one is at least _legitimately_ large but has annoying point 
releases every once in a while that trigger a rebuild for little 
benefit. Again, expect ~24h.

* net-libs/webkit-gtk: if you're avoiding firefox (which is huge, 
and requires rust, which is huge), then this is your best bet for 
a browser engine. Even if you don't use it directly, other apps
like evolution (mail client) can pull it in. It too is huge, just
not as bad as the others. This one finishes in something like 18h 
for me.

Everything else that's packaged well and uses a sane programming
language shouldn't give you much trouble.

libreboot cant microcode updates, pretty much all dead now

ie cat /sys/devices/system/cpu/vulnerabilities/*

LLVM is annoying even on my current machine but I already avoid rust

if it would be worth the 50-70 bucks, though. That's more than what the computer costs!

Do you have any other (more powerful) machines at home that you could
set up as a distcc cluster? I've run Gentoo on a T420 and X220 (so two generations newer than your X200), using my home desktop [i7-6700K] as a
distcc host for updates. It's livable, but definitely the kind of thing
where I'd kick off an emerge --update and leave it running for several
hours while I'm doing something else. I've also upgraded mine to 8GB
RAM which helps with certain builds.

In addition to the usual problem packages others have called out, the
main problem I ran into was heat dissipation: the X220 chassis is so
small that railing the CPU at 100% for hours on compiles was pushing the temperature over 90 degrees celsius. I disassembled the laptop and
applied new high quality thermal paste to the CPU/heatsink and it seems
to be doing a little better now.

GTK itself doesn't *really* need it. You'll just get warnings (and no
image) if it tries to render an SVG for some reason. ffmpeg and
imagemagick only need it to convert SVGs, which you can do with
inkscape instead. I'm not sure about djvu but I'd guess it's the same.

GIMP is annoying. It doesn't actually need librsvg for anything but
importing SVGs, and it used to be completely optional. The maintainers
have removed the option however, and don't want to put it back. In
theory it would be trivial to patch out (their words), but I haven't
bothered to try it.

My desktop is only slightly more powerful. I don't really mind the

I just run that (and/or gcc) overnight when I need to.

I have an old Acer laptop with a Core 2 Duo P7550 @2.26GHz CPU and only 4G RAM. It will compile everything, even rust and qtwebengine, although it may take more than a day to achieve this. Hence I use a more modern PC to build binaries which I then transfer and emerge on the laptop in minutes.

Or, use some blocks/books to suspend it off the desk. A couple of inches may be enough. Alternatively, you can buy a cooling pad. Some come with USB powered fans too, which help drop the CPU temperature by another couple of degrees.

Hi everyone,

So I've found a Thinkpad X200 online and I'm thinking of buying it for libreboot purposes. Do you think the P8600 cpu can handle all the
compiling on gentoo? For the record, I don't have any of the "big stuff" like KDE, GNOME, Firefox (all I have is Tor Browser [which I don't compile], dwl and some terminal programs like neomutt and profanity). Surely, I wouldn't be spending 5 hours to do small upgrades,
right?..right?

Thank you

libreboot cant microcode updates, pretty much all dead now

ie cat /sys/devices/system/cpu/vulnerabilities/*

I actually disable all the mitigations on my machines. Those issues are
mostly relevant for shared hosters and cloud providers which require tight isolation of their processes. For a personal machine at home, those
scenarios are mostly irrelevant, unless you click on every link you
encounter. I prefer performance. Besides, could it be possible that the
P8600 isn’t even vulnerable to Spectre & co, being so old?

@Topic: I‘ve been migrating my X250 (Broadwell i5, 2/4 threads) away from Gentoo because build times kept creeping up. If you want to play and
experiment and do upgrades only once in a while, go for it. But I’d also recommend binary packages and/or using distcc. Back in the day I had Gentoo running on a puny netbook with Atom N450 (1/2 threads, with a quarter of the P8600’s single-thread performance) and 2 Gigs of RAM, so packages were usually built on a beefier machine. I even built firefox on it once just for giggles, it took a day to build. But didn’t start any faster. I’ve been using bin packages whenever possible anyway, as I didn’t see any advantage over the effort.

Do you have some more powerful machine in the background? If yes, you can either create binary packages on this machine and only install them on your laptop, or use distcc for moving the big compilation tasks to this other machine.
Using binary packages, I can still use a Lenovo SL510, which seems to have similar properties regarding CPU and RAM than the X200, with all desktop programs, including full KDE/plasma, Firefox, libreoffice, etc.
