Innocent old me. It’s been years since I have even thought about /etc/X11/xorg.conf and I thought I never would have to again. Wrong.
Today I updated Fedora Linux on my PPC workstation and on reboot, I had lost my GUI login. That turned out to be because the systemd gdm.service had failed, because the X server had failed, because… well, because it had no conf file.
These days you’re not supposed to need one (it’s meant to auto-detect stuff during boot) but after the updates, this install needed one.
I generated one with the Xorg command, and while that command errored out, it seemed to generate a complete-looking config file. With fingers crossed I dropped it into place and rebooted and it Just Worked[tm].
Not a fun thing to debug, but I am glad to have solved it.
#linux #fedora38 #power9 #xorg

@orowith2os yeah, I might. My issue is a known bug, I commented on the relevant github issue.

Being on the #POWER9 architecture does slow things down a bit as there are fewer people using that. (not to mention #guix which insists on reproduceable builds which is another delaying factor)

@ted_dunning @profoundlynerdy @Houl the only.asvantage is that #SPARCv9 & #POWER9 are #FLOSS'd like #RISCV so the limiting factor would be economies of scale and the ability to procure fabbing, which sadly isn't #FLOSS'd yet ( #LibreSilicon works on that!)...

This literally bit #Russia in the rear as #TSMC canceled any deliveries for #MCST's chips they fabbed on 28nm nodes...

@filterpaper it's perfect for me, because my #guix install locally regularly breaks (#power9 arch is not that stable yet) and this way I can at least update my keyboard, which is obviously a primary life need ;-)

So guess who gets to play with a Talos II while his friends on vacation? Me. #ubuntu #power9 #guix #openbsd What should I do on this supercomputer? Also I do need to get a modern web browser set up and try to get his AMD graphics card to work.

Anyone here have a computer running on a #Talos II mainboard?

It is recommended by @fsf for its #FreeBIOS. It is well out of my budget at the present time, but I'm just curious to see if anyone uses it here.

Just looking cost / performance comparisons with a CPU that I have, and the #POWER9 is about 6 times more expensive per operation.

@vikings @fosdem Just visit and use a toolcart with embedded #power9 machine? 😜

I'm a fan of #power9 on #raptorcs as open source hardware and I'm wondering, are there any other examples of commercial, completely open, hardware out there? Something less expensive perhaps? Still seems hard to find.

My #power9 machine distro (#archpower) does not provide a #telegram desktop package.

Compiling it is far from trivial, so I cobbled together a container spec which works almost flawless. Based on the telegram package availble in #debian #ppc64el Drawback is that no apps from the host can be used; e.g. the web browser can not be used to open links directly, as the telegram app runs in the container.

Much faster than using the telegram web version.

Ironically the new HMC is #power9 and uses OPAL to boot, so go figure!

Lo so è un po' una poracciata però mi sfizia un bel po'

@jrozanski the machine is my daily driver

highlights: many vm-s, compiling packages (guix/yay), development in python/lisp/scheme/haskell, testing/simulating server loads.

If it is suitable for what you outline I can`t say. I personally would be ok with it.

The machine has excellent IO options, great multithread performance, mediocre single thread performance.

It`s basically a server oriented design.

https://wiki.raptorcs.com/wiki/Main_Page is a great resource for all things #talos and #power9

First #ppc64 patch for #guix submitted!

There's a ton of work needed for the ppc64 platform in guix.

#power9

The #power9 #talos computers are so freaking powerful that i doubt you would need to upgrade that computer anytime soon.

Dear lord, a 16 core processor is 64 threads of execution.

@ruffni@mstdn.io rebuilding is very slow, guix pull also takes forever for example.

I'm on a #power9 machine, so it may be early days.

At the moment, it's just not a workable solution.

Perhaps it's me.

bootstrapping a compiler...

That's a first in, I dunno, 25 years. Last time it probably was gcc on an HP-UX (apollo 425 I think) cluster I bought from university leftovers

I'm sort of getting used to having 'changeme' as the name of my #power9 workstation. Probably should change it before it's 'muscle memorized'

#til I never used `comm` before; handy for keeping track of which packages I still need to migrate to a new machine:

`comm -23 <(pacman -Qenq|sort) <(ssh #power9 'pacman -Qenq'|sort)`

#openPOWER #POWER9 CPU heat spreader removed.

CPU was destroyed in the process. Removal of said heat spreader is probably straightforward if you can guarantee a max. depth of cut.
