Mobaxterm SSH client: stay connected after sleep.

Linux Questions - Wed, 10/05/2022 - 11:42
Hi

I use the Mobaxterm ssh client and need to know how to configure it to stay connected after coming back from "sleep" mode!?

compared it with 'putty', I logged in using both, next day (say after 18 hours) I found putty is still connected while Mobaxterm disconnected!

for sure it's not a server error..

any idea?

Intel Laptop Users Should Avoid Linux 5.19.12 To Avoid Potentially Damaging The Display

Slashdot - Wed, 10/05/2022 - 11:00
Intel laptop users running Linux are being advised to avoid running the latest Linux 5.19.12 stable kernel point release as it can potentially damage the display. From a report: Intel Linux laptop users on Linux 5.19.12 have begun reporting "white flashing" display issues with one user describing it as "[the] laptop display starts to blink like lights in a 90's rave party." Intel Linux kernel engineer Ville Syrjal posted this week on the kernel mailing list: "After looking at some logs we do end up with potentially bogus panel power sequencing delays, which may harm the LCD panel."

Streaming music from Ubuntu server - like a "radio station" for my LAN

Linux Questions - Wed, 10/05/2022 - 10:55
Hello good people. I've searched here (and elsewhere) to no avail for information on setting up a streaming service on my Ubuntu server. I want to stream music to my local area network. Right now I have miniDLNA running on it and it works fine but that's not what I want. I want streaming music so it can play the same thing on whatever client is listening to it - sort of like "Muzak". I have a very robust wi-fi network here - two routers, one acting as an access point. I envision using one of them via a "guest network" to stream the music. Is this even possible?

The server is a headless one and is running the 64-bit Ubuntu LTS release 20.04.1. Would Ampache be the ticket for me?

Thanks in advance for any info you might have.

memtest86+ missing from my boot grub menu!

Linux Questions - Wed, 10/05/2022 - 10:41
Hello.
I'm running Ubuntu 22.04 (recently upgraded) on

Code: uname -a
Linux kinsella-OptiPlex-5060 5.15.0-48-generic #54-Ubuntu SMP Fri Aug 26 13:26:29 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux It is fully updated to Ubuntu 22.04.1 LTS

In the process of chasing a possible kernel problem on another thread I noticed that memtest86+ is missing from my boot grub menu.

(I had been advised to use it to check that I don't have a memory problem.
In my defence, I had't noticed as my system hasn't had any boot problems and the boot menu is "hidden".

Code: $ grep hidden /etc/default/grub
GRUB_TIMEOUT_STYLE=hidden )


I'd be very grateful for advice on:
  1. How to restore memtest86+ to the boot grub menu
  2. possible reasons why memtest86+ "disappeared" from the menu.

Interestingly, memtest86+ does appear in my boot folder:

Code: $ ls /boot
config-5.15.0-47-generic      memtest86+.elf
config-5.15.0-48-generic      memtest86+_multiboot.bin
efi                          System.map-5.15.0-47-generic
grub                          System.map-5.15.0-48-generic
initrd.img                    vmlinuz
initrd.img-5.15.0-47-generic  vmlinuz-5.15.0-47-generic
initrd.img-5.15.0-48-generic  vmlinuz-5.15.0-48-generic
initrd.img.old                vmlinuz.old
memtest86+.bin Thanks.

debian-installer adding new udeb package

Linux Questions - Wed, 10/05/2022 - 09:30
Hi All,

i have created a new udeb package which ask for an URL, then i store the value into a debconf variable. This value is used by a debian .deb package to be installed by debian installer , in the postinst script. This deb package contains a .config file, used with dpkg-reconfigure command in case the value entered at install time via udeb has to be updated.

But at install time :
- i can see the question (url) from the udeb, this is good
- but also interface from .config file when the .deb package is installing

How can i ask the debian installer to not show the .deb config file and its questions ?

Regards

Installation of Slackware with Grub + UEFI (and isolinux/syslinux) ?

Linux Questions - Wed, 10/05/2022 - 09:10
Hello

Herewith the installation of Slackware in screenshot. fdisk allows to create the partitions.

How do you create a bootable harddisk, with Slackware, and with Grub + UEFI (and isolinux/syslinux) ?

> It would be expected:
GRUB is shown when the USB Pendrive is booted on EFI-capable machine.
SYSLINUX or Grub2 is shown when the USB Pendrive is booted on BIOS-only machine.



Likely, the rootfs should be at (hd0,gpt2).

What are first steps?


Kind regards


Ref.
https://docs.slackware.com/howtos:sl..._uefi_hardware
https://askubuntu.com/questions/6519...b-and-syslinux

Slackware for instance is readily bootable with:
Code: Device                                        Boot Start    End Sectors  Size Id Type
slackware64-14.2-install-dvd.iso1 *        0 5416959 5416960  2.6G  0 Empty
slackware64-14.2-install-dvd.iso2      2948    5827    2880  1.4M ef EFI (FA Isolinux is on hd0, gpt (beginning).

[SOLVED] QT6

Linux Questions - Wed, 10/05/2022 - 07:29
Quick question, don't want to start a flame war or anything. Just noticed that the pre-release version of Protonmail Bridge-2.4.0 has switched over to QT6 and I don't recall having read about qt6 in Slackware in recent times. The QT5 version works fine for me and if it craps out there is always the browser interface. So what's the status, if known? The pre-release version runs fine on Win 11 fwiw. Thanks

Contextualizing Ambrose Bierce

Linux Questions - Wed, 10/05/2022 - 06:40
It seems to me that Bierce was satirizing some set of opinions when he wrote this: Quote: Three great scientific theories of the structure of the universe are
the molecular, the corpuscular and the atomic. A fourth affirms, with
Haeckel, the condensation or precipitation of matter from ether --
whose existence is proved by the condensation or precipitation ... A
fifth theory is held by idiots, but it is doubtful if they know any
more about the matter than the others.
-- Ambrose Bierce, "The Devil's Dictionary" As someone who has not heard of any of his universal theories which have doubtless past their 'best before' date anyhow, what was the guy poking fun at?
