New laptop derecommendations

I'm looking for a new laptop.

I am NOT looking for recommendations (but if you have them, by all means
send them directly to my email address) because I suspect one or other
variant of Ubuntu will run on pretty much all modern laptops.

What I am looking for is warnings: DON'T use XYZ laptops because...

Knowing what to avoid is probably more useful than knowing what to
choose from, and I already have a checklist of things it MUST have.

I have been using an ancient but reliable Dell Latitude D810 through
many versions and distros of Ubuntu.

shell pipe "loses" parts of the data, was: help needed to debug Perl script

Hello all, again

(sorry, this is a bit long, but it can't be helped)

in another thread today, I wrote how a Perl script I had been using
for weeks without problems had suddenly started to drive me mad, losing
~80% of the data it was supposed to print.

Basically the script was telling me "I have built a hash with ~26K keys,
and now I am going to print them all, one per line", but instead of ~26k
lines of data, it would only print ~4700.

OT: help needed to debug Perl script

Greetings,

A few weeks ago I quickly put together a Perl script to parse big CSV
files, for a project I am working on (I need to do this several times a
day, always with new data).

Install a printer driver

Hi,

I am having problems with getting a Brother MFC-J485DW printer to work
with Linux.  I am using Mint - Rebeca and the Mate desktop.

I deleted the profile for my old printer and then connected the printer
to my computer with a USB cable.  When I turned the printer on a pop-up
window said that "No printer driver for Brother MFC-J485D.  (It is
obvious that there is some communications between the printer and the
computer.) I clicked on the "search" button.
A new pop-up window that gave three choices 1. Select printer from
database  2. Provide PPD file and 3.

Cannot run a program at boot that uses a serial device

I have a couple of Python programs that will no
longer start at boot time.  This was working until
yesterday afternoon just after a did a reboot.
There haven't been any changes to either program,
but I did do an update (upgrade and dist-upgrade)
a few days ago. I cannot recall if I did a reboot
at the time though. I'm guessing that I did not do
the reboot until yesterday and that my problem
might be due to the upgrade.  Using systemctl
status command revealed that  USB serial device
could not be found which caused the abort.

What are the differences between systemd and non-systemd Linux distros?

Good afternoon from Singapore,

What are the differences between systemd and non-systemd Linux distros?

Is systemd implemented in all the latest Linux distros?

Please advise. Thank you.

18.04 has no support for my printer

Hello Ubuntu Support

18.04 looks good until I discover that I cannot print. Your advice will be
a huge relief.
Maybe I could restore files from 16.04 backup but have no idea which files
I would need?

Many thanks.

Desktop brief anomaly

Hi,

Ubuntu has just behaved very strangely. I booted my computer, logged in and
all my desktop icons had disappeared.

I thought that was strange, went into Firefox and started using it.
Suddenly, without warning, I was logged out and facing the login screen.

Logged back in again and the desktop icons were back again and now I'm back
in Firefox, passing on this message.

Weird,

m4a/aac file formats

Hi,

I have a new MP3/AAC player with some problems reading the metadata on
some of the m4a files, so they come up "Unknown Artist" and "Unknown
Album", even though I've made sure the tags are correct using easytag.

The file command gives
ISO Media, MP4 v2 [ISO 14496-14]
for the ones the player handles correctly, and
ISO Media, Apple iTunes ALAC/AAC-LC (.M4A) Audio
for the ones the player mangles.

I may have ripped some of the files with grip a few years ago, but the
recent ones are all ripped from CDs using abcde.

changing default grub entry??

Hi sisters & brothers in unbuntu

I swaped my motherboard in a 16.04 box with 5 disks.

Now the boot sequence has changed.

I would like to have the 9th entry of the list that is displayed when I boot, to

this is what I tried (and failed):

1. in /etc/default/grub

    GRUB_HIDDEN_TIMEOUT_QUIET=true
    GRUB_TIMEOUT=10

How do I disable hot key combinations

How do I disable what I believe are named hot key combinations?

I am using UbuntuMATE linux 16.04.x, and, I can be typing text into a
form, and then, a half hour or so, of text typed in, suddenly
disappears and the screen hanges to show that something has happened,
and I am not sure what has happened.

I am losing about an hour's typing, each day, because of whatever is
happening, and, I am assuming that it is due to some inadvertent and
unwitting key combination.

The mouse keeps bringing up menu's in web pages, when it is not
supposed to be doing that, but that is another problem.

Hibernate 18.04

Hi

Or maybe more accurately "Resume" after Hibernate

I've Googled (& DuckDuckGo'ed) for an answer that works, all tests of "if
hibernate should work" are positive

I could Hibernate & resume under 16.04 and the dual booted Win7, but didn't as
that screws access from Ubuntu to Win partition (as win cant read Ubuntu...)

Since I upgraded to 18.04 it stopped working, Hibernate does close down but
after re-boot it's just like a clean cold boot

'Emacs style' delete line shortcut (CTRL/U) doesn't work correctly in Firefox

I have the 'Emacs style' keyboard shortcuts enabled on my [x]ubuntu
18.04 systems. The shortcut I use most often is the (not really
Emacs) CTRL/U for deleting a line of text.

This should delete the whole line of text even if the cursor isn't
placed at the end of the line. It *does* do this in other GUIs but in
Firefox it just deletes from the cursor to the start of the line.
This makes the shortcut much less useful as it means I need to move
the cursor to delete the line and this means I have to use the touchpad
or mouse.

who maintains mailman 2.1 for ubuntu 18.04.1?

know a) who that is or b) how to find out (apart from asking here).

Anyone?

Are these instructions meant to be executed on Ubuntu Server 18.04 LTS?

Good afternoon from Singapore,

I came across this Linux Journal article titled "DIY: Build a Custom Minimal Linux Distribution from Source", written by Petros Koutoupis.

Please advise.

Which project should I use to submit sleep / power management bugs with ubuntu-bug?

Hi there folks.

I'm running Ubuntu 18.10 beta on my Alienware 17 R5 and I want to report
a bug about the fact that if the machine goes to sleep it won't come
back and I need to power cycle it.
I thought maybe Xorg but that path leads nowhere as there are no options
for power management.
Any suggestions anyone?

Thanks in advance!

Excessive Logging problem in /var/log

Dear all Ubuntu Users and developers,

I have a problem. More than 4G in this directory

Software Updater broken on 16.04.x

Hello.

On one of my computers running UbuntuMATE 16.04.x, the Software
Updater shows "Updated software is available for this computer. ..."
and "323.1MB will be downloaded.".

But, it now does not display a (selectable/deselectable) list of what
packages are to be downloaded/updated/installed/removed/changed.

This also occurs after the computer is rebooted.

I am not aware of any setting to conceal what packages are to be changed.

What is happening?

Release-upgrade broke internet connection

Hi!

The hint, that /etc/resolv.conf should probably point to
/run/systemd/resolve/resolv.conf was correct. The connection is back.

Now, my desktop (after being online again) sucks all the mail from my
mail provider, and places it in my local IMAP server (Dovecot). Which
doesn't work yet. There are problems with kmail. So, at the moment, I
don't have a working email connection any more. (Last, I've used a
webmail interface).

I have to repair my mail connection, before I can answer any mail.

Bye, and thanks for that hint!

Hi

I've done a do-release-upgrade on my 16.04 LTS system. This has broken

Openbox quite messed up on Ubuntu 16.04, need sample config files..

..or so it seems on my own computer, at least.

I used openbox a lot years ago, customizing it with pipe menus and other
stuff as I needed, then migrated to other window managers. This week I
wanted to try it again, so installed openbox, obmenu etc.. but:

the openbox root menu is almost empty, and I haven't found any
*working* way to make it display the same menus of applications that
kde, enlightenment etc...

evolution error on first start

I've installed evolution and on first running it, from a terminal, I
get:

I've looked in /usr/lib/evolution-data-server/ and sure enough there
isn't a file or directory called credential-modules. I'm not surprised
in a way because I haven't provided any credentials. My understanding
is that a first run wizard will start up to solicit such information
but this has not happened. Ideas?

Settings

I am running Ubuntu 18.04.1 with no customizations

Where did the settings get move to as they are no longer on the settings icon?

Yesterday I had the system set up the way I wanted it. An update was done and
now today the configuration of the monitors has changed. I went to settings to
change it back to the way I wanted and the settings are no longer there. I
also want to change the settings for system updates but they also seem to have
been moved somewhere else.

This is reminding me of MS where every update they change where things are
located and do not care about the users.

Why does Ubuntu 18.04 doesn't create multiple BTRFS subvolumes anymore during installation by default?

Hi all,

during installation of Ubuntu 16.04 LTS Server I could choose manual
partitioning and create a /-partition using BTRFS. The installer
automatically mapped that to creating one subvolume called @ for /
itself and and another one called @home for /home.

That doesn't seem to be the case anymore for UB 18.04 LTS Server, I
only managed to get one BTRFS subvolume for / itself if I only create
one partition.

He started with Mint, then something else

to show up at all. In each OS there is
only ethernet.

Ive not dual booted so Im not sure this is
something normal or what. Though looking
in the mint forums a lot seem to have problems

time.

We did go through and install broadcom
drivers but it didnt seem to work.

Turning off pam for Unix Authentication completely disables Passwords

In my quest to keep things simple and easy, I used to use
pam-auth-update to disable PAM from Unix logins, (this would disable the
password 'complexity' inanity, and prevents pam from automatically
re-enabling it when it updates itself.). However, with Ubuntu 18.04,
that completely disables passwords entirely. Is there a way to
re-enable traditional login?

USB question

I play music stored on my PC via a USB connection to my DAC.

The player (HQPlayer) does not detect the DAC after a reboot unless I

This suggested to me that some module was not automatically loaded at
boot, so I did lsmod before and after re-inserting the cable to see if
there was a new module in the list after re-insertion.

Canon MP272 printer on 18.04

I have a Canon MP272 printer which works fine on 16.04 but although my 18.04 sees it, it can't print to it. All the articles I've found point to the Canon driver page, which only has 32 bit available. Can I use that driver? Seems unlikely, but I can't find a 64-bit driver.

sound control on 18.04

I upgraded to 18.04 from 16.04 yesterday.

Ubuntu option.

I have looked for hours for a way modify this applet (if that is what it is

Along the same lines you can not access rhythm box and VLC from that

Perhaps this is no longer possible. Any thoughts on the matter?

help with serial i/o from a device?

Is there a linux Driver module for Elitech data logger RC5 ?

Hi to Everyone,

This 'Elitech data logger RC5' is a temperature recorder available from
amazon. From the online notice, it is supposed to be a "windows only"
system. However, quite a few such apparatus can operate at least
basically on linux, either directly (the system appears as a usb device
once connected to the computer), or through a debian or ubuntu module
available.

Could anyone tell me if this may apply to the 'Elitech data logger RC5',
and what would be the name of such module ?
