Postings by Xen


Funnily enough my local town has a primary school called "Oeboentoe".

I didn't know but there is a million children on the street in front of
my house holding some "Oeboentoe" banner up above their heads ;-).

auto configuration systems

I just want to ask here colloquially.

The promise of Linux is of course that you can modify your own system.

But if you do; you run into the issue of perpetuating your changes.

Keeping configuration alive through many installs is not very useful;
and hence you seek a way to regenerate config or to reapply it from some
config system that you design or use from someone else.

I am sure there are millions such systems in the world because everyone
pretty much develops his own thing :p.

But are there any well known such systems that you use?

For example I had a set of patches that would tu

system boots extremely slow with AMD R9 GPU

I was actually just meaning to ask here,

that my Linux system boots very slowly when I have inserted a AMD R9 380
graphics card.

I don't know how to say it now, my message was aborted because I
attached a dmesg log.

Both when running kernel 4.4.0 and 4.8.0 on a Kubuntu 16.04 system the
booting takes almost indefinitely long, both during the kernel
initialization, or actually mostly during that, after a while the system
is functional.

Basically the kernel takes extremely long before it even enters the
systemd stage.

I am talking about several minutes before it hits SystemD.

Remove NetworkManager


I just wanted to remove NetworkManager because it was interfering (once
more) with manual setting of my connection in case I needed to change
the DHCP server temporarily and I just...

want to be able to use "ip addr" myself and it interferes with that.

However after removing the service and the package I still get

I also uninstalled dnsmasq.

There is still some dhclient process being started by something and I
don't know what, leading to /usr/lib/NetworkManager/.....

Plasma started crashing

So I an an update today but now that I think of it I also exchanged a
graphics card (same driver, no driver exchange).

I don't know which is which at this point but plasmashell crashes about 10
times per hour.

I assume it is going to be the graphics card. Makes KDE nigh unusable
though. One problem gone (the tearing with the other card) a new one
arises (I have had another card in there, so of the say 3 cards in my
possession from nVidia, 2 don't work. And this is just a very new card,
nVidia GTX 950).

It doesn't get much better does it...

streak across the screen

I have the streak across the diagonal of the screen in KDE now too.

(With a different graphical card).

The GT 640 I have doesn't do it, this is some older cheaper card that

I guess I'm off to Cinnamon again :(.

Cannot disable kwallet

I had already set up kwallet to "satisfaction" and yet on every logon
the kwallet migration assistant keeps bugging me.

I decided to turn kwallet off, but I cannot do so. I can turn it off in
kwalletmanager5, but then every single application that uses it, or
wants to use it, will cause prompts for creating a new wallet (chrome,
opera, etc.) so I cannot effectively turn the subsystem off even though
kwalletmanager5 would have said that it is turned off.

kwallet not working

I reinstalled Kubuntu 16.04.

With a default created user of course.

First thing that happens is that it presents me with opening a wallet
the moment some program like Chromium-browser starts. But my user
password doesn't work on it. I delete the wallet and create a new one
with an empty password. That used to work. But now it doesn't. Maybe
because I have chosen blowfish, I don't know.

What is the procedure of actually getting this working?

encrypted system fails to boot when Sil3132 is present.

How can I debug a failure in the initrd boot sequence if and when a root
filesystem cannot be loaded?

I have a Sil3132 SATA RAID controller card that when installed into the
system (even with no harddisks on it) will cause my (encrypted) system
to fail booting.

The first thing that visibly happens is that the volume group on which
the root partition is situated, cannot be found.

"Volume group "linux" not found"

But before that the crypt device opens *fine* -- this happens both on
Kubuntu 16.04 and Mint 18, which ...kinda stem from the same roots.


- crypt is getting unlocked and

KDE freezes for me.

I just want to mention that I have regular KDE GUI freezes and I have no
clue what causes it.

It is about as nonspecific as it can get. I suspect the rest of my
system keeps functioning as normal, so I just activated dropbear (I
hope) as an SSH server so I can at least reset KDE from outside the

I didn't have this on my previous install on the same computer, slightly
(say 2 weeks) before 16.04 was released, and until I installed my new
system, some time later.

The mouse will freeze, the clock will keep ticking, and animitions
continue to animate.

IO blocking under load

I wonder if anyone can answer the question why or how a system could be
experiencing total IO blocking for basically all processes under certain

I am meaning to say that on this current system, I have experienced the
majority of processes getting IO blocked (because they were reading from
the disk what was seeing the "choke") for as long as 120 seconds or

Meaning: the entire system becomes unresponsive (if this is the system
disk) if any process actually does try to read from the disk.

qtchooser / qdbusviewer (ksnapshot / spectacle)

On my system (16.04) there is:

qtchooser: /usr/bin/qdbusviewer
qttools5-dev-tools: /usr/lib/x86_64-linux-gnu/qt5/bin/qdbusviewer

qdbusviewer will try to start

qt4-dev-tools: /usr/lib/x86_64-linux-gnu/qt4/bin/qdbusviewer

but is not installed.

installing requires 146 MB additional diskspace.

/usr/lib/x86_64-linux-gnu/qt5/bin/qdbusviewer works fine when directly
invoked, but from KDE it also doesn't work as it probably starts

I was trying to discover how to replace Spectacle with KSnapshot as I
consider the latter a vastly superior program at least in terms of user

default font of Konsole

I would suggest changing the default font of Konsole to Liberation Mono
pt 10.

Also the thing has been bugged for a long time and if you change the
font of the default profile, next time chances are high it will have
reverted to the old, which is way too small.

16.04 live dvd: locale

In the live DVD I changed my locale somewhere in KDE.

the new setting resulted in LC_ALL=nl_NL.UTF-8

It is not installed however:

kubuntu@kubuntu:~$ locale -a

and resulted in utf8 filenames no longer being displayed correctly.

Notice that "UTF-8" in general would probably have been wrong, it would
have needed to be "utf8" ?

I believe I only changed the locale for

a simple video editor that works


I have for the previous few hours been trying to cut out a little bit of a
youtube video and be able to upload it elsewhere I guess.

I first tried kdenlive but it froze the moment I started playing the

It is just an mp4 from YT @ 720p.

Then I tried Openshot. It kept crashing for a while but eventually I
learned how to rudimentary reduce the video to a small section.

15.10 fails to boot thin-LVM

I have a 15.10 install that I copied onto a thinly provisioned LVM. After
this change, the system wouldn't boot anymore. I'm not sure about the
exact error messages at this point, but suffice to say for now that there
were errors about the thin-volumes not being able to be loaded. This may
actually have to do with the package thin-provisioning-tools not being
installed by default, or not being included in the initrd.

I can't regen my initrd at this point due to the other problem of not
being able to chroot into my install.

chroot fails into kubuntu system


I am trying to chroot into an installed Kubuntu system. Version is 15.10,
just before the beta.

Fwd: My document is nearing completion

I sent this with the wrong account last Wednesday, and it was rejected.


still not sure if anyone is wanting it, but...

I have my document about the design of the website (in structural
terms) ready almost.

It is not perfect, but on paper (or PDF, in full view) looks much
better than in the small format of a Calligra window.

I was surprised by how readable it really is once you expand your
scope a little, once you allow yourself to be treated to a normal
experience (such as a printout).

Maybe it

Re: New site Feedback

Erm, let me just summarize that piece a bit, it is a bit of a chaos writeup it

1. I have a WPML version that is the latest version and that might still work
very well in WP 4+. It has a feature that in its (desired) mode of having a
language URL as "" the default language also uses
that setup, ie. a default language of english comes up as
Apparently it does not work fully for pages (static pages) yet but that should
be easy to fix with a bit of time.

Also, that behaviour can be removed again, probably not all that hard.

experiences alpha 2


completely new to Kubuntu and Linux :p, but I had the wish to get Kubuntu
Vivid on Ubuntu Server with some kind of LUKS setup.

Experiences thus far, in short:

- Vivid installer is fine, no issues. Encryption is dysfunctional though.
