Applications and Porting / Wayland support/port for PPC64el
« on: December 30, 2020, 06:21:11 am »
Hi All,

I've installed Fedora 32 (server and later added KDE/Plasma desktop) on my Blackbird and upgraded to F33 when it was released.

I cannot connect to Zoom (on any browser like Chromium or Firefox) and just found that the issue is that I do not have support for Wayland installed on my system.

Anyone here uses Wayland on Raptor P9 machines?

I do not have a graphics card/GPU. I run video directly through the embedded HDMI port that is integrated with the BMC.

Thanks in advance.

Hi All,

I've followed the instructions found on this link

I've created KVM VMs using Debian 10.7 ISO images but when trying to install non-qubes-whonix-gateway-xfce or non-qubes-whonix-gateway-cli I could not solve dependency issues.

Has anyone succeeded creating these VMs?

I have them working on a x86 machine with the same Fedora33 I use on my Blackbird.


I've found the issue preventing sandbox to work. Opening SeLinux Troubleshoot I saw that Selinux was the issue and, at the same time, found there a solution. With a few commands it is now working:

sudo setsebool -P domain_can_mmap_files 1
sudo ausearch -c 'Xephyr' --raw | audit2allow -M my-Xephyr
sudo semodule -i my-Xephyr.pp
sudo semodule -X 300 -i my-Xephyr.pp

and voila.. it works.

Hope this may help someone one day trying to run a sandbox on Fedora/SeLinux.

By the way, I'm running perating System: Fedora 33 (Thirty Three) Kernel: Linux 5.9.8-200.fc33.ppc64le

Hi Guys,

I have installed policycoreutils-sandbox and I'm trying to open firefox in a sandbox run this command: sandbox -X -t sandbox_net_t -t sandbox_web_t -w 1920x1080 firefox

The error message:
(sandbox:8075): Gtk-WARNING **: 21:34:28.459: Theme parsing error: gtk.css:2:33: Failed to import: Error opening file /home/claudio/.config/gtk-3.0/window_decorations.css: No such file or directory
/usr/bin/firefox: line 186: getenforce: command not found
/usr/bin/firefox: line 186: [: !=: unary operator expected

Any ideas?

Thanks in advance

Hi guys,

I found the issue here ( The right commnad to create a new /boot/grub2/grub.cfg from the installed kernels is "grub2-mkconfig -o /boot/grub2/grub.cfg" and not just "grub2-mkconfig" as I was doing.

Thank you all.

No idea. It just worked. I would remove it and install it again.
Hi MPC7500,

I've removed and reinstalled the three RPM packages (kernel-5.8.18-300.fc33.ppc64le.rpm kernel-core-5.8.18-300.fc33.ppc64le.rpm kernel-modules-5.8.18-300.fc33.ppc64le.rpm) but it did not work.

I've changed /boot/grub2/grub.cfg to a different name and ran grub2-mkconfig but no new /boot/grub2/grub.cfg was created. So I've changed back the name to /boot/grub2/grub.cfg and booted. On Petitboot I only see what's in /boot/grub2/grub.cfg.

If I issue command "rpm -qa kernel" I get this as a response:

If I issue command "rpm -qa | grep -i kernel" I get this:

It is really frustrating!

This works for me: How to install a kernel from koji
Hi MPC7500,

I read the article you sent and got excited because I realised I had installed just kernel-5.8.18-300.fc33.ppc64le.rpm, so I've downloaded kernel-core-5.8.18-300.fc33.ppc64le.rpm and kernel-modules-5.8.18-300.fc33.ppc64le.rpm and run "sudo dnf install kernel-5.8.18-300.fc33.ppc64le.rpm kernel-core-5.8.18-300.fc33.ppc64le.rpm kernel-modules-5.8.18-300.fc33.ppc64le.rpm". The result was:

Package kernel-5.8.18-300.fc33.ppc64le is already installed.
Package kernel-core-5.8.18-300.fc33.ppc64le is already installed.
Package kernel-modules-5.8.18-300.fc33.ppc64le is already installed.
Dependencies resolved.
Nothing to do.

I've checked /boot/grub2/grub.cfg, which had not changed. I've run grub2-mkconfig but grub.cfg did not change.

I've booted to see if something had changed but no, nothing changed.

Can you give me some additional advice? this is first time I try this and maybe I missed some important point.

Thanks in advance.

I assume it doesn't show up either as an option in Petitboot.
Yep. All I see on Petit boot is what is in grub.cfg.

Any idea?

Operating Systems and Porting / How to test a new kernel

I've upgraded from Fedora 32 to Fedora 33 and I want to test kernel-5.8.18-300.fc33.ppc64le.

Issuing command "sudo dnf upgrade --advisory=FEDORA-2020-6bac1c305f" (see I can see files initramfs-5.8.18-300.fc33.ppc64le.img in /boot directory.

When checking file /boot/grub2/grub.cfg there is no kernel-5.8.18-300.fc33.ppc64le option available. I've tried running grub2-mkconfig but /boot/grub2/grub.cfg remained unchanged.

I've then downloaed kernel-5.8.18-300.fc33.ppc64le.rpm from and run "rpm -ivh kernel-5.8.18-300.fc33.ppc64le.rpm" and the response includes "package kernel-5.8.18-300.fc33.ppc64le is already installed". Still /boot/grub2/grub.cfg does not contain kernel-5.8.18-300.fc33.ppc64le.

What am I missing here?

Any help is much appreciated.


It's not related to compacting mails. It looks like it gets slow/freeze every time it syncs with the servers and updates my many folders.


Thunderbird on my Blackbird often freezes for a few seconds during which I have to wait patiently, while on my Dell Latitude 5590 notebook it runs much smoother. Here are the two setups:

Blackbird SW: Thunderbird 78.0.4 64 bits runs directly on the host (Fedora33 - kernel-5.8.18-300)
Blackbird HW: Power9 v2 4 cores, 32GB and two SSD M.2 disk (128 and 256GB)

Dell SW: Thunderbird 78.3.1 64 bits runs on a VM (2 vCPUs and 400-4000MB RAM); host running Qubes OS R4.0 (updated to the last minor version), Linux 4.19.152-1 with Xen 4.8.5-25-fc25
Dell HW: Intel i5 8th gen, 16GB RAM and 512GB SSD M.2 (pretty average specs)

My suspitions:

1. The Thunderbird port to ppc64el is not optimized for the architecture, relative to the x86 version. Do not take me wrong, no complains. I'm thankful to whoever ported it.
2. My /home logical volume on the Blackbird (where Thunderbird stores my mail boxes) is split between the two physical disk, which in turn are each connected to a different PCI slot.
3. I have this feeling that after upgrading Blackbird from F32 to F33 it got worse.

Any feed-back is appreciated.

BTW, once I tried to install Windows 10 on a VM using QEMU. I was a pain because it was extremely slow and frustrating because in the end the install failed. Anyway, that Windows binary iso must have compiled for 4K memory Pages but QEMU seems to have handled that, I guess.

Yeah, I know. It's just that Classic wrote "loading PE binaries, which have 4K aligned sections, into a 64K page comes with [lots] of problems, so currently the best approach is to avoid that". So I asked if it was worth trying anyway.

Exactly. You'd need something like Hangover to do that.
Hey Classic,

I've just read your article ( about Hangover and visited the project page (

Is there a binary that I can download and test?

I read the warning about 4 vs 64K pages. I'm using Fedora 33. Is it worth trying?
