[clug] Upgrade from Ubuntu 12.04 to 14.04 has destroyed Gnome customisation


Hi All,

I am totally p!$$ed off!

I have an eeePC with a 10.1" screen. About a month ago I upgraded from
Ubuntu LTS 12.04 to 14.04. In the process I stupidly answered "no" to
all the prompts to accept the default configuration hoping that all the
customisation of my Gnome windows - with many thanks to this list -
would be saved, but I lost almost everything that I like about Gnome.

I don't like Unity. I want a simple menu list with categories that I can
edit. During the upgrade I ended up with a stack of categories that I
don't want, don't know how to change and are so long that I can't see
the last few categories or their applicaions because they are off the
bottom of the screen. (I don't even know how to screen capture to show
this list the mess that I'm in.)

I also had the options at the top panel automatically hide itself so
that I can fully use the limited screen space. I also added my favourite
applications to the top panel eg. Midori, Evolution and ebReader. Those
options are now lost.

I also had the bottom panel automatically hide itself to fully use the
screen space but that option has gone. The bottom panel used to show
*all* the applications so that I could easily switch applications no
matter what window it was in. That option has now gone. I can only see
in the bottom panel the applications that apply to that window and not
the other windows.

[clug] .bash_aliases and .bashrc

People have posted their favourites before...
Here's a couple I use that I haven't seen elsewhere. Peer review
wouldn't hurt me.

I'd also be interested in what other people find useful.

Replace "su -c" with "sudo" if you use it.

~/.bash_aliases

[clug] Programmable title

I have the following in the config.fish file.

function fish_title
     echo $_ 'shell '
     tty | cut -c 6-8
     echo ' on line '
     echo (tty) | cut -c 10-
end

So the terminal window title reads as follows.

"fish shell pts on line 0"

I would like that to substitute instead of "pts" rather "pseudo terminal".
In the case of being a "tty", then I'd like the title to say "terminal" 
instead.

[clug] Debian Jessie (Testing, ) "no installable kernel was found in the defined APT sources"

    Hi, 

I recently tried to install Debian Jess using VMware Workstation 10,
and the installation fails with the error "no installable kernel was
found in the defined APT sources". Has anyone else seen this issue ?

I finally succeeded using the following suggestion from a web site.

The solution I found was to let the installation continue (say Yes to
the message asking if you want to continue without installing a
kernel).

 Then, when the final prompt "Installation complete" appears (i.e.
the one that appears just before it goes down for reboot), do the
following:
1.Press Alt+F3 to switch to a virtual console, then press Enter to
activate it.
2.Type "apt-install linux-image-amd64"
3.Wait for the prompt to re-appear (you can monitor progress by
pressing Alt+F4, but you must Alt+F3 to see whether it's actually
finished)
4.When the installation of the kernel is complete, press Alt+F1 to
return to the installer, and press Enter with the Continue button
highlighted to reboot the system

Re: [clug] NFSv4 "Invalid argument"

Check umask settings maybe? - if it's set to default, then any new file
being created by virt-manager in the ISO directory may not have the
read-write permissions that it needs.

Has anyone got any of the three monitor cards working with 3 monitors under linux?  

Any recommendations?  Any pitfalls?

[clug] NFSv4 "Invalid argument"

    HI,

I am unable to understand how NFS works with user permissions.  Does
anyone have experience with NFS shares in Debian Wheezy and could
explain to me how to manage user permissions for an NFS share ? Maybe
it is not even needed?

I searched the Internet but did not find anything useful, I did find
mentions of libnss-mysql and nfs4_disable_idmapping but I could not
find any detail on how this related to Debian.

[clug] [OT] Supporting a FOSS project

Prof Steve Keen is raising money to keep his programmer going, he’s been working unpaid for last 6 months.
Donations can be made via PayPal from a ‘Donate’ button on the page

<http://www.debtdeflation.com/blogs/2014/10/02/assistance-for-minsky-required/>

The FOSS project was Sourceforge’s Product of the Month last January.
It’s a generic Dynamic Modelling framework, not solely Economics:

<http://sourceforge.net/blog/january-2014-potm/>

I wouldn’t be raising this on-list if I hadn’t already given.

One side of FOSS is using the free software, the other side is supporting the developers.
For those of you who don’t already have a considered “gifting programme”, I encourage you to think
about it.

[clug] Seeking FOSS Hypervisor and Management GUI

     So far I have always created VMs and servers with all files in
the one partition. I have not understood any usefulness for having
separate partitions. My main concern is that I do not know how large
to make the partitions and fear they will fill up as updates are
installed. Some operating systems are like that.  I have one
application that wants to install itself to /usr/share and thus takes
up space I would not have necessarily provided for.  From my limited
understanding, it is /var/log and in particularly /home that are known
to grow large, where as I would expect the other directories (what
should I call them?) like /etc /bin /sbin, etc will only increase
slightly, if at all. I guess partitioning would be a topic of its own.

$ virsh snapshot-list
http://wiki.libvirt.org/page/VM_lifecycle

As for FOSS Hypervisor and Management GUI, my efforts for installing
Virt-Manager 1.1 seemed to have not completely succeeded. When
attempting to use my installation of Virt-Manager 1.1 I found that
there was no Connect/Disconnect for the CDROM, thus I could not add or
remove CD/DVDs or ISOs of CD/DVDs.  In the end I uninstalled and
reinstall Virt-Manager 0.10 which then left me with no GUI for
managing snapshots.

I have yet to try restoring from snapshots or consolidating snapshots,
however I have now used the command line to take snapshots (took a
while for the first snapshot to be taken).  I tried to take a
snapshot of a powered down raw image but of course it would not do
this, the image has to be Qcow2. I also took a live snapshot and a
snapshot of the VM when it was shutdown.

[clug] Virt-Manager & snapshots Vs Xen


I was using KVM with Virt-Manager under Centos 7 and Debian Wheezy and
when I went to take a snapshot of a 6 TB server before applying
updates, and found that there was no snapshot support. For me
snapshots are a base requirement for any virtual machine. For example,
before applying any updates to a virtual server, take snapshot,
install updates, test running software to see nothing as broken,
delete snapshot while consoldiating image, or if the changes cause
issues, roll back the image to the snapshot and live without the
updates until you can apply them without causing issues.

Searching on the Internet I discovered that Virt-Manager >= version
1.0 can take snapshots if the image is qcow2.

http://blog.wikichoon.com/2014/03/snapshot-support-in-virt-manager.html
The biggest feature we added in virt-manager 1.0 is VM snapshot
support. ... Only works with qcow2 disk images. ... While the overlay
files have to be qcow2, these snapshots will work with any base disk
image. They can also be performed with very little VM downtime, at
least under a second. 

When checking both Debian Jessie and CentOS 7, I discovered that
Virt-Manager was < version 1.0, so using standard packages was not
going to be a useful solution. I will be pleased with these OSs
upgrade to a virt-manager that can support snapshots,but it could be a
long while away.

Going to the Virt-Manager home page, I downloaded the latest verison
of the source code, "virt-manager 1.1.0 Sunday September 07, 2014", 
http://virt-manager.org/download/
