ed2k-ovmf missing "4M version"
by Sam Varshavchik
It seems that Win10 guest VMs are now choking after Microsoft did …something
to reject the current OVMF firmware.
This entire discussion, pretty much, is way over my head:
https://github.com/tianocore/edk2/discussions/3221
As best as I can make things out:
There is an alternative OVMF firware called "4M" firmware that works.
The edk2-ovmf package contains files named OVMF_CODE.secboot.fd and
OVMF_VARS.secboot.fd which are blacklisted by Microsoft.
Debian and other distributions apparently ship "OVMF_CODE_4M" and
"OVMF_VARS_4M" firmware which is still good. People have reported success
extracting those images and repointing their qemu VM configuration to them.
I don't grasp the underlying issue well enough to be able to file something
intelligent in Bugzilla, in order to update Fedora packaging. I'm hoping
that someone else here has enough domain knowledge to create a bug that
points the ed2k packagers in the right direction. I tried looking at the
SRPM, and I did not see anything in there that I could understand.

wired headset and its integrated media controlling buttons issue
by Mgr. Janusz Chmiel
Dear elite developers, dear users in this mailing list,
Please, who of us know, if it would be possible to extend sound
devices support so wired headsets with The integrated buttons on The
microphone would be supported by not only Fedora distribution?
My dream is, that those wired headsets with buttons on The microphne
could be used as A alternate media controlling system on Mate desktop
environment.
But I do not know, if Alsa, Pulseaudio and The similar sound subsystems
support this technology. Or if it is impossible to implement at all?
I know, that The majority of users are using bluetooth devices. But
wired headsets have also its advantages.
Sure, if kernel device drivers would had to be reprogrammed from
scratch, I Am aware, that nobody will invest such plenty of time to
support wired headsets and their media controlling integrated buttons.
Mate can not grab such media keys as A keyboard code, so I can not
simply assign those media codes myself.
I Am very sorry for this non standard question.
With The deepest appreciation to all members of this mailing list.

encryption and flash based media question
by Mgr. Janusz Chmiel
Dear specialists,
I would like to know, if enabling encryption of Fedora installation
in Anaconda installer will dramatically short The life cycle of SSD disk
or USB flash drives or SSD memory cart?
By other words. Does enabling encryption enforces much more write
requests on file system when comparing with not encrypted partitions?
Thank all engaged Fedora kernel developers for encryption kernel module.

kworker leftovers
by Geoffrey Leach
Fedora 35, not fully up-to-date
I run a SiliconDust tuner that converts OTA TV to mp2, which I'm then
able to play back using mplayer. An hard-wired ethernet connection is
used between the tuner and the main CPU.
I notice that there are leftover kworker processes. They are mostly idle
and only a few have non-zero time, and then at most only a couple of
seconds.
For example,
87547 ? I 0:00 [kworker/u16:1-phy0]
87554 ? I 0:00 [kworker/7:2-events]
87555 ? I 0:00 [kworker/5:2-events]
87556 ? I 0:00 [kworker/u16:2-btrfs-endio-write]
87557 ? I 0:00 [kworker/u16:3-btrfs-delalloc]
87558 ? I 0:00 [kworker/u16:5-btrfs-endio-write]
87559 ? I 0:00 [kworker/u16:7-events_unbound]
87560 ? I 0:00 [kworker/u16:9-btrfs-freespace-write]
87561 ? I 0:00 [kworker/u16:10]
87626 ? I< 0:00 [kworker/u17:1]
The leftover processes seem to vanish when the system is suspended.
Should I be concerned? In particular, I was not aware that I had
installed the btrfs filesystem.
Thanks.

Boot Hangs When Ethernet Cable Plugged In
by Peter G.
I have recently started using the ethernet instead of wifi. I have not disabled the wifi, but I leave the ethernet cable inserted. Recently, I noticed that I was unable to start the computer. I thought it was a faulty F37 testing kernel, so I tried the previous kernel. Same thing. For some reason, I thought the only thing different is that I now have the ethernet hooked up, so I pulled the plug and tried to boot. Everything went fine.
How come I cannot boot the computer with the ethernet cable plugged in?

some positive words about anaconda installer and fedora kernel
developers
by Mgr. Janusz Chmiel
Yes,
It is time to express some positive attitude to very professionally
developed Anaconda installer.
Why do I have such need to publicly express my feelings?
The reason is, that I have never found so professionally created Linux
system installer.
What do I like best on The Anaconda installer?
User do not have to be afraid, that GRUB boot loader will be
accidentally put to his internal harddisk if user want to install Fedora
to some available USB bootable arbitrary media such as flash disks or SD
carts.
Next reason is, that Anaconda is The only one Linux operating system
installer which really care about professionaly configured FLinux
installation if user choose USB bootable media.
As A result, file system is correctly closed if user shut down system
booted from USB bootable media.
No file system corruption. No. Realy, file system is correctly closed
and I can safely turn on and off again and again even if I install in
such non standard botable device such as SSD cart.
I Am aware, that those achievements could be never reached without elite
Fedora kernel engineers.
Many users do not know, that without reliable and professionally
debugged kernel, kernel device drivers, their operating systems would be
The only source of pain and chaos.
So I would also to like express my deepest possible appreciation to all
Fedora kernel developers, who are spending many many hours of their
spare time to bring The secure and reliable kernel to us.
As a result, Fedora is not only stable and high performance Linux
distro. It is also reflecting new security issues, because kernel teams
are doing their best to also protect us against hackers.
So I would like to thank The Anaconda developers and also kernel
developers, because without The cooperation of those teams and very
professionally working developers, Fedora would not be so good Linux
distribution.
Fedora is also very popular Linux distribution in Czech Republic.
Students and absolvents of informatic ciences in our country have
created special Fedora flavour called Fegora.
It contain Mate desktop and Chromium accessibility support is prepared.

linux intelligent ocr solution settings dialog problem
by Mgr. Janusz Chmiel
Because I do not see at all, I have "fallen in love with" excellent app
named Lios.
It is complex app writeen in Python and it uses GTK 3 toolkit to create
its GUI.
Unfortunately, on Fedora 35, 36, some dependent Python component was
changed. As A result, when ever user want to access The settings dialog,
which is necessary, app hang. No errors are printed to The terminal
related to Python language errors.
So I Am having big plea to Python developers here.
Would you be so kind and would you try to debug and find The cause of
this problem please?
Github source code tree of this app LIOS is here:
https://github.com/Nalin-x-Linux/Lios
One absolvent of informatic science in our country has told Me, that The
problem causes new version of Pygobject introspection library or The
similar name.
May be, that advanced Python developers will find The exact cause and if
it could be solved even by having development debate with The author of
Pyobject introspection library.
Thank you very much for your help.
With kindness regards.

is it possible to start non kernel dependent services in fedora
chroot container
by Mgr. Janusz Chmiel
Dear advanced users and programmers in this excellent mailing list,
I have The following polite plea addressed to you.
I want to use Fedora 36 with The Mate desktop environment, Orca screen
reader and Espeak on my ANdroid 8.0 phone.
I must relay on non rooted device, because it is possible to use Fedora
thanks to Termux and Proot package for Termux.
But I do not know, if I can start some services which are not developed
to interacting with Fedora Linux kernel or hardware.
I can not use officially supported command systemctl for this task.
Is it possible to safely start or stop userspace based services which do
not communicate with hardware or with Fedora Linux kernel in chroot?
Or unfortunately, I must receive sad reality, that I can not control
services at all in chroot mode?
Thanks to VNC protocol, Tigervnc and Orca and Pulseaudio for Termux, it
is really possible to run Mate desktop environment including Marco
window manager. Sure, some apps which depend on consolekit daemon will
display warnings, but those warnings are not visible on X11 session screen.
Sure, there are massive limitations because of up to date Firefox,
Seamonkey or Chromium.
those browses are using shared memory very intensively and it is no more
possible to run them by using Proot and Termux on Android.
But fortunately, not all apps are so depend on shared memory calls. As a
result, it is possible to run even Pidgin, Libre office apps and many
many others including Audacity for playing or editing sound data. Not
for recording.
I know, that professional developers do not like such approach. Because
it is always big security risk to combine Android kernel with userspace
chrooted container.
But because I do not want to work for big professional company and I Am
only running Fedora for my personal pleasure, I Am hoping, that elite
programmers will forgive Me this approach.
Thank you very much for your answer.
With The deepest appreciationa nd with The kindness regards.

microphone not work with skype on fedora 36
by Mgr. Janusz Chmiel
After I have upgraded from Fedora 35 to 36 by using The following commands.
|sudo dnf upgrade --refresh|
|sudo dnf install dnf-plugin-system-upgrade sudo dnf system-upgrade
download --releasever=36 ||--allowerasing|
|sudo dnf system-upgrade reboot |Upgrade process have been finished successfully with no hangs or errors.
I have installed skype .rpm package from The official Microsoft WEB pages.
I have used dnf install skype.rpm
Original article link.
https://docs.fedoraproject.org/en-US/quick-docs/dnf-system-upgrade/
There is some sound configuration problem. Because Audacity also do not
record sound at all from internal microphone by default and it have
always worked before.
It has 100 % worked reliably on Fedora 35.
Unfortunately, Pulseaudio volume control app do not allow me to increase
Thew mic volume by using cursor keys. When I position on The recording
TAB, I can only hear combo box with several sub system names including
monitoring build in analog stereo
When I Am speaking waves are being changed, because The graphical
symbols on The display are created by using The progress bar so Orca
scren reader play random sound because The Progress bar percentage
indicators are changing.
But how to setup The build in microphone?
May be, that The package installation of VMK virtual midi kpiano has
installed some sound modules which has caused The issue.
Thank you very much for your advice.
