Monthly FAQ for debian-user mailing list
an-user is a mailing list provided for support for Debian users, and to facilitate discussion on relevant topics. Some guidelines which may help explain how the list works: * The language on this mailing list is English. There may be other mailing lists that are language-specific for example debian-user-french * It is common for users to be redirected here from other lists - for example, from debian-project. It is also common for people to be posting here when English is not their primary language. Please be considerate. * The list is a Debian communication forum. As such, it is subject to both the Debian mailing list Code of Conduct and the main Debian Code of Conduct https://www.debian.org/MailingLists/#codeofconduct https://www.debian.org/code_of_conduct * This is a fairly busy mailing list and you may have to wait for an answer - please be patient. Please post answers back to the list so others can benefit; private conversations don't benefit people who may be following along on the list or reading the archives later. * Help and advice on this list is provided by volunteers in their own time. It is common for there to be different opinions or answers provided. * Please try to stay on topic. Arguments for the sake of it are not welcome here. Partisan political / religious / cultural arguments do not belong here either. Debian's community is world wide; don't assume others will agree with your views or need to read them on a Debian list. * There is an FAQ on the Debian wiki derived from some questions asked on this list at https://wiki.debian.org/FAQsFromDebianUser * One question that comes up on almost all Debian lists from time to time is of the form: "I have done something wrong / included personal details in an email. Could you please delete my name / details / remove the mail" Practically, this is impossible: the mailing lists are archived, potentially cached by Google and so on. Unfortunately, there is nothing much we can do to ensure that all copies anywhere on the Internet are deleted. Asking to do this may only serve to draw further attention - the so-called "Streisand effect" https://en.wikipedia.org/wiki/Streisand_effect Problems? = Complaints about inappropriate behaviour should be referred to the Debian Community Team . Inappropriate behaviour on the list may lead to warnings; repeated bad behaviour may lead to temporary or permanent bans for offenders.

You can't have a bug-free system, you can't have a stable system, and you can't have an up-to-date system. You can lean closer to any two of those by getting further from the third. In general, each Debian stable=>stable upgrade has been less disruptive than the previous one. A distro can go to a rolling release, but that means that either something is broken all the time or there is only one canonical way to do things: a notional Debian "Luxo" rolling release that tried to produce a stabilized stream from testing would require twice as many Debian Developers, or an 85% cut in the number of packages, or perhaps both. -dsr-
having high cpu problem related to kernel version
note that i'm using debian sid and xfce4 it shows full of red bars on htop on one of the core between two(i have atom n455 cpu) iirc red bars means kernel threads i've tested using debian's boot menu so only thing changed is kernel version it was fine on kernel 5.10 it's happening on kernel 5.14 and 5.15 i don't know exactly how to represent, but it isn't hard to if i just do something like browsing or reading pdf it just starts to happen and never stops even after i close all apps or log out https://asciinema.org/a/xTXqyZhg06enfrcHbuhasGJrm https://asciinema.org/a/y0klCFDWSOsjjAQTUHlHM84mq 1st link is when it's fine(right after boot) 2nd link is when it happens there is no difference on application running between two xserver is unrelated it's high cpu usage is just because of more updates on htop screen if i watch htop on ctrl+alt+f1 terminal xserver isn't even on the first page but htop still shows high cpu usage https://asciinema.org/a/l81ZO3hSHbA4jLm6fwLlIrfUS recorded on ctrl+alt+f1 terminal ran htop as root and enabled to show kernel threads tho cpu usage of kernel threads aren't being displayed

But it certainly would be nice to at least be able to use my old jupyter notebooks, even if it's unlikely that I'll create any new ones. Judging from [1], you're required to reinstall all these "jupyter kernels", because what you have was installed for python2, but what you need is to install them for python3. But then again, I could be wrong. Sorry, cannot help you further. That's probably a good bet. I don't remember how any of those kernels got installed [I thought that all except the sos kernel were from debian repositories, but my memory might be faulty], so I'll have to search around and see what I can dig up. The evidence to hand does seem to suggest that they don't auto-upgrade and therefore need to be upgraded manually somehow. Thank you for taking the time to share your thoughts, especially as you don't use jupyter yourself. Doc -- Web: http://enginehousebooks.com/drevans

What I do know is: a) /usr/bin/python was python 2.x in Debian 10. b) Python 2.x and python 3.x modules are not compatible nor they are interchangeable.

Solved! Re: pulseaudio only finds one sink but alsa shows all
Success! I copied the default.pa file into my local .config and uncommented the line: load-module module-alsa-sink Initially, I tried adding device= options to this line (as the manual suggests) but I could not get the right incantation. Without it, PA found the device just fine as a possible sink although, funnily enough, it does not appear in the configuration tab of pavucontrol... I did leave the udev module, as Didier suggested. I did have to use alsamixer to adjust the volume (to the maximum, letting PA then have control up to that maximum). Thank you all for the help in solving this mystery. I remain wondering why it stopped working last year... but it's good to have some mystery left. ;-) eric -- Eric S Fraga with org 9.5.2 in Emacs 29.0.50 on Debian 11.2
