No sound after update
by andreas.fournier＠runbox.com 26 Sep '22

26 Sep '22

Today I updated the software on my Fedora 36 and now there is no sound. I used Gnome Software to update. Neither VLC nor Firefox produces sound. In Settings -> Sound -> Output there are two values under Output Device, both saying HDMI/DisplayPort - Built-in Audio. No difference between them, when using the Test functionality both stay silent. Any advice?

ed2k-ovmf missing "4M version"
by Sam Varshavchik 26 Sep '22

26 Sep '22

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 25 Sep '22

25 Sep '22

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. Mgr. Janusz Chmiel

encryption and flash based media question
by Mgr. Janusz Chmiel 25 Sep '22

25 Sep '22

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 24 Sep '22

24 Sep '22

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. 24 Sep '22

24 Sep '22

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 23 Sep '22

23 Sep '22

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. So visually imp

linux intelligent ocr solution settings dialog problem
by Mgr. Janusz Chmiel 23 Sep '22

23 Sep '22

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. Mgr. Janusz Chmiel

is it possible to start non kernel dependent services in fedora chroot container
by Mgr. Janusz Chmiel 23 Sep '22

23 Sep '22

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. Janusz Chmiel
