First official non-testing Chimera Linux 32-bit PowerPC images have released today.
If you haven't heard of it - it's a relatively new distribution founded by the creator of Void Linux PPC that's built with a little non-standard building blocks at it's core (core tools from freebsd, llvm, musl).

It is very interesting.
Adrian Glaubitz said, that LLVM stil supports SPE extension...

the graphical isos aren't going to work well in general due to mesa being broken on big endian upstream, the unresponsiveness is probably due to it attempting to start display manager in a loop and failing
so don't bother with anything but base and install whatever graphical stuff later (alongside mesa-amber to replace regular mesa, since that should have working gpu drivers) and don't bother with anything wayland on ppc32 because the gpus are never going to be new enough

Thank you. I will wait a little when more be fixed and give a try with Chimera.
And about ppc32 computers - Sam460LE and A1222+ has no problems with modern cards. Btw, are there any other 32-bit computers with PCIe?
And A1222+ is surprisingly fast with classic fpu non-spe system. With lxde desktop is much more responsible and usable than Sam460LE. Two cores are counting. Office and even Gimp are fine here. Of course, no 3D games or more heavy desktop.
But we will see if last kernel for A1222 will be modern enough for Chimera.

Hi.
Install Chimera on a empty partition. Just extracted chimera-linux-ppc-ROOTFS-20250214-full.tar.gz to the disk. then I booted with vmlinux-6.12. . At the prompt I logged in with root and chimera.
Tried to install something with apk , but there is no working network. I get the error that can be seen in my photo (segmentation fault) every time I try to use the apk command. Set the correct date and time with the command date 202503092245.
Have a nice day

Looks like the crashes I was getting after the debootstrap Debian install I tried. Which also was also crashing in package manager. Did you run dmesg to check log?
While it won't help in the direct system you could try to chroot to your Chimera volume from a working Linux and see if it can work. Seems there is something missing from the Chimera rootfs. Or they expect you to setup network already. Either way, crashing is not a good sign, and reeks of bad coding.
Example chroot if Chimera was mounted to /mnt:
Code: Select all
mount -t proc /proc /mnt/proc/
mount -t sysfs /sys /mnt/sys/
mount -o bind /dev /mnt/dev/
chroot /mnt

Hi
@Hypex thanks but I have installed Chimera 64 instead and everything works here,
but because of the mesa bug I can't get a graphical login (black screen).
I have tried renaming libglamoregl.so but that's not enough.
Can mesa disables?
Have a nice day
edit: A little bit closer . I got a working mouse now and a black screen
New edit: install mesa-amber and get a graphical login. Unfortunately my X1000 kept saying it wouldn't work.
Maybe it will again tomorrow when it has had a little sleep on it.

Hi
I have solved the problems I first had with Chirema by installing the 64 version.
I have created a user, new password and given the user the groups whell and plugdev.
I have installed mesa-amber and plasma-desktop.
Then sddm start and on to a graphical login. After that everything is so slow that it can't really be used for anything. Over 5 minutes to log in and after welcome, black screen.

So on your system your graphics is supported with 3d? I've known problems with login and desktop managers that refuse to work with 2d. But if you have 3d drivers that won't be an issue.
Have you installed an xorg config file from a working system in case it needs it? I'm not aware of how to disable mesa apart from renaming the library. Which looks like a slight hack that could fail.
Another thing is if you have two graphic cards you can see the symptoms you describe:

Hi
I have solved the problem with no speed. I had forgotten to rename back libglamoregl.so after installing mesa-amber.
I am running xfce4 on this screenshot. I have some problems with permissions for my user. I can't open usb drives for example.
