LibreOffice bundled with Ubuntu 16.04.3.

Hello again.

In regard to my problems with LibreOffice in a recent message, I have just
downloaded, verified, and reinstalled the 16.04.3 LTS available from
canonical. This installation process seems to install a version of LO that
is older than the one available from the software centre.

I've remove the preinstalled LO and install LO Writer only. Even though
both installations say they are version 5, the installation from the
software centre has a completely different look and feel.

GRUB question


I'm trying to set up an SSD cache for my hard disk. Just in a virtual machine,
so far.

It's for my (encrypted) root filesystem. According to the instructions
(<a href="" title=""></a>), the
following is needed when the root filesystem is to be cached. Otherwise, it
won't be able to boot:

echo "dm_cache" >> /etc/initramfs-tools/modules
echo "dm_cache_mq" >> /etc/initramfs-tools/modules
echo "dm_persistent_data" >> /etc/initramfs-tools/modules
echo "dm_bufio" >> /etc/initramfs-tools/modules

Now, how do I make this take effect?

Notebook won't reboot after nvidia driver install

I think I goofed up....

My displayport doesn't work riht, and Nvidia has a newer driver than
the one in the Xubuntu repository (340.104, vs 340.102).

I downloaded the driver from nvidia's web site and installed it.

Now the notebook won't boot at all - I'm running off a flash drive.

It keeps stopping in busybox. I've tried going back to recover mode
and previous versions that used to work fine, and it's just plain

gthumb and gvfs


gthumb 3.4.3 doesn't display images on gvfs mounted smb-folder.

I'm using 16.04.3 LTS (Xenial Xerus).

I've found a bug report [1] from 2010 and it was fixed. Do I have to
change any settings?

Task Coach 1.4.3 in Ubuntu 16.04.3 LTS


I don't know if this is the right place to ask. Maybe one should file a
bug in debian's tracker, but there's already a similar one [2].

The TaskCoach version mentioned above has some strange issue with a
python locking library. When trying to open a tsk file created on
windows (don't know if this matters):

File "/usr/lib/python2.7/dist-packages/lockfile/", line
279, in _fl_helper return cls(*args, **kwds)
TypeError: __init__() takes at least 2 arguments (1 given)

It seems that the upstream authors know about this bug and fixed it in
their own ppa [1].

Can anyone tell me what is wrong with LibreOffice?

Hello again.

My faith in LibreOffice has been tested these few years because it seems
that large pieces of it haven't been functioning for a while. The format
paintbrush mechanism apparently hasn't been working for about two years.

Recently, I've been trying to use LibreOffice for the first time after I
installed 16.04, and I find that the spell checker is broken for Australian
and UK English.

unity error in a 16.04 LTS installation


I faced today a strange issue regarding my unity desktop app.
In particular, the launcher and the side bar along with the top bar that
displays time etc and all of the buttons such as minimize, maximize etc

I tried to reinstall unity by typing the following command:

sudo apt-get install --reinstall unity


sudo apt-get install --reinstall ubuntu-desktop without any success.

Moreover I read in a thread somewhere that the side-bar plugin may have
been disabled.

php-fpm status info under Ubuntu 16.04..

 On an older Ubuntu 14.x with php5 I had this status info put on a web
page with some other stats with no problem.

 On my Ubuntu 16.x server now using php7 I seem to be pulling out the
remainder of my hair, so wanted to see if someone could hit me with a
cloo bat so I can get this straight.

should be accessible, this seems to be the same as in the older php5.

The print job from hell... :(

Hi all,

My wife's PC (running Debian Wheezy) has our Laserjet attached, and I
can access it from my PC (running Ubuntu 16 LTS) as a shared printer.

I printed a PDF yesterday, but now every time we turn the printer on,
it starts printing that same PDF again!

I've looked at the print queue on my PC - it's empty. I've looked at
the print queue on Pat's PC, it's also empty. I've tried switching the
printer off, I've tried cancelling the job on the front panel of the
Laserjet. NONE of these things work.

To format Disk for ZFS or not ?

Setup for a dash cam.

I want to ask this question now, before I purchase a dash cam, because I
don't want to purchase one and find that it won't play with Ubuntu because
of flimsy bespoke compatibility minutiae.

Does anyone know a good hardware/software set up? I would think a dash cam
that recorded to a well known video format on a USB device that I could
mount simply by plugging it in is all I could ever need. Editing the
footage may be a concern at a later stage, but if it was, I would want to
worry about this at that later stage.

Anything like this?

Is there a way to disable it? Possibly by lying to apt about my terminal's

Systemd service files


I have Ubuntu server 16.04 LTS deployed on one of my servers. I have been working at slowly learning systemd but I ran into something that I hadn't expected.

When adding commonly used packages (Apache 2.4.x), I noticed that some of these packages have incomplete systemd service files. In the case of Apache there is a systemd stub that then calls an init.d shim script. As a result, on reboot, systemd shows a load failure (I am assuming from the incomplete service file), for Apache, but Apache is successfully started.

Kernel compiled with Stack Protector ?


In light of the recent report from Armis about the "BlueBorne" Bluetooth vulnerabilities that affect Linux (and other OS's), I was wondering if Ubuntu compiles the kernel with Stack Protector enabled (specifically for Ubuntu 16.04 LTS desktop and to a lesser extent 16.04 LTS server) ?

Secondly, is there a page that outlines the hardening steps that Ubuntu follows for ensuring kernel security ?

Printing oddity with Canon Pixma MP240 on CUPS server

I have a Canon Pixma MP240, quite an old item, but it prints, scans and

Worked well! Then an unfortunate incident involving a laser printer and

CUPS and made the old inkjet into a networked printer. There is a CUPS
driver just for that model, so that was good.

Geeqie is a nice tool I use when looking through a photo

there no matter what I do.

I'd appreciate any suggestions for recovering from this. Running 16.04

Software Updater messages

Hi all.

I'm getting a stream of messages from Software Updater's terminal read
out when I use it. They're mainly Perl errors but there's too many of

I've looked in about every log file for any trace of the read-out but to
no avail. Does anybody know where I might look so I can act on the errors?

Any help appreciated.



Planned Maintenance Advisory - Ubuntu Mailing List

Over the last week or so we've been having some issues with the mailing

We contacted the Canoncial engineers and they have been very responsive in

secondary screen only works until login


I'm using 16.04 on a Toshiba laptop. I want to use a secondary display,
a Samsung SyncMaster 712n. I have it connected to the Toshiba's
external VGA port. The display powered up and showed system activity
right up until the automatic user login took place. I had the system
configured to log me in without asking for a password. When the login
took place the secondary display went blank. The system control panel
shows an unknown secondary display.

In an attempt to see where the problem lies I made a new (second) user
with a password and required a credential check at login.

Two ubuntu bugs


I wanna report two bugs in (K)Ubuntu 17.04.

The first one is in the (K)Ubuntu installer. When you enter the new passphrase,
the keyboard is still in English localization. When you're German, this means
(among other things) that the keys Z and Y are interchanged. When you log in,
after the install, the keyboard has been localized.

The second one is the "ubuntu-bug" program.

Different kernels in same Xubuntu (16.04.3)

Do the ubuntu repo offer an conglomerate sort of perl pkgs

Sorry the Subject line is a bit confusing... couldn't think, right off
hand, of a good way to express what I mean briefly.

I run into some perl pkgs missing every once in a while, that I'd like
to get installed but would rather not have to screw around with cpan if I
can help it.

I'm a recent gentoo user where we had quite a lot of perl pkgs
available thru the pkg managing tools (emerge and friends) called

I wondered if apt has something like that.

This is just this last hour been installed (17.04) into a Vbox vm

Is the largish console being done in the kernel using KVM settings or

Whatever way it is, how can I make it even bigger.

I think it is 1024x(something close to 800 maybe)

I'd like to try something like 1400x1050 or there abouts.

Anyone know how to go about something like that?
