Chucked another computer tonight. This one had been ill for about a year and stopped working about two months ago (the Raspberry Pi now does all that it used to do, except run a SCSI tape backup).
But I had to rescue an LVM set to get the files – so here’s how I did that:
At first all I could see was the
/boot partition, so I plainly needed to do more:
sudo aptitude install lvm2 – get the LVM software.
sudo pvs – see what LVM groups I have.
I could see that Volume Group (VG) called
Ubuntu (it will be whatever name you gave it when created – in my case about six and a half years ago).
lvdisplay /dev/Ubuntu – gives me details of the volumes inside the group – in my case just the one (ignoring swap), identified by
vgchange /dev/Ubuntu/root -a y – this makes the volume mountable (assuming it is marked as
unavailable before then.)
mount /dev/Ubuntu/root /your/mount/point – from this point you should be able to access the files on the volume.
- Basic instructions for using LVM on SCE for a dynamically attached volume (ibm.com)
- Lvm (wiki.archlinux.org)
…and I could really do with an answer to this question I have posted over on “Superuser”:
I am seeking to back up an encrypted volume used by Virtual Box on one OS X machine to another using rsync (I will eventually stick this into cron).
This is the command line (I am sharing public keys so no password is required) – with some details obscured:
But it won’t copy anything, just repeatedly giving me this, ie no copying is done – despite the fact that ubuntu1.vdi date stamp and size have now changed:
How do get this to work properly?
I cannot believe that Microsoft feel so threatened by Ubuntu and Canonical that they have done this deliberately, but it still seems like a very odd choice to me.
PS: Remind me never to use OS X to write blog posts – this is the second time I have tried it and every time I do, the text gets deleted. A bug somewhere.

It looks as though my wireless bridge, which relied on equipment more than a decade old – a Ricoh pci pcmcia bridge and a 801.11b DLink card – has died. The network interface won’t come up on booting the system and
lspci just lists the device as an unrecognised non-VGA card (interestingly the BIOS still sees it as a network controller though).
So, I need to replace it. But with what? My understanding, last year at least, was that Linux bridging software won’t work with anything more modern (this card had an old Prism II chipset)
. Has that changed?

Admittedly this is a “focus group of one” but returning home from some weeks away, the other half says “you know the way my computer works now?” Me: “oh, Unity?” Her: “Yes. Well, it’s ****. Can you get rid of it?” Me: “I thought you said you liked it?” Her: “That was before I had to do some work.”
But it seems Canonical still are not prepared to admit their mistake.

The first half of this blog’s title was a search string that took someone here. I tend to agree.
So is there a way to seamlessly switch to Mint? I don’t have a separate
/home partition so the route that most people seem to recommend is blocked to me.
I think there used to be scripts but I cannot find any up to date ones, so can anyone help?

OK, after a week of 11.10 I thought I’d list some of the problems and what to do about them. It’s not happy reading – I think it is fair to say Canonical have dropped the ball on this one.
- Unity – this is the joke Ubuntu think we should be using as a desktop interface. It’s rubbish, just use Gnome:
sudo aptitude install gnome-paneland then select Gnome when you login (click on that wheel thing beside your name on the login dialog).
- Evolution – this is nearly as bad as the Unity decision, but Ubuntu have banjaxed Evolution and I can see no obvious fix – I am using Thunderbird instead, but it is also broken (a bug is in the Ubuntu bugzilla but no fix is apparent) and complains about the Ubuntu One address book. You just have to ignore the errors and hope somebody gets around to fixing it. Better yet, gets round to fixing the distro so that Evolution works on it.
- Skype – this too is broken by 11.10. But it can be fixed.
sudo apt-get install libxss1:i386 && sudo apt-get install libqt4-core:i386 && sudo apt-get install libqt4-gui:i386 && sudo apt-get install libdbus-1-3:i386(NB: use
aptitudeseems to have some issues with this.) Be careful, though, as installing these libraries might cause you some other issues – have not for me, but they seem to drive a lot of other consequential changes.

I have now upgraded the laptop on which this is being typed to Ubuntu 11.10 and there were a few problems and issues:
- The upgrade killed the wireless connection and then failed (late on) because it could not download the Adobe Flash installer – but it was late enough in the upgrade process to allow me to boot into 11.10 and then complete anything that needed doing with
sudo aptitude dist-upgrade
- You are forced to use the abomination that is “Unity” – still looks and feels like something a five-year-old would have designed. It’s a disgusting waste of time. You can probably tell I don’t like it. So get rid of it with
sudo aptitude install gnome-panel
- Before I got to that point it tried to boot into something called “Ubuntu 3D” – which is something to do with the ludicrous Unity. It failed (this is running dual head) telling me I was exceeding the 3D capacity of my video card (at least that’s what I think it was trying to tell me) and then went into “Ubuntu 2D” – which worked reasonably well.
The issue I had with the desktop background disappearing when going dual head has gone, though Gnome panel handled the dual head properly while Unity 2D still had “issues”.
But, overall, it seems to have gone well enough. At least once I got rid of Unity. Have I told I don’t like it?
Five years ago I was a Fedora user but then they issued a release that oopsed on booting, so I had no choice but to use Ubuntu and until the release of the awful “Unity” desktop have never thought of using anything else.
I guess I would just go straight to Debian if starting from scratch these days.

Can confirm that I need both commands:
iwconfig wlan0 mode master
Not quite sure why as obviously the hostapd service comes up on boot and the
/etc/network/interfaces file has that exact mode setting line. But the bridge comes up with the wireless card disabled and while the mode setting line will enable it, it requires the hostapd restart to work.
Anyway, the fact I know what to do means it is easy to restore the network to full capacity, but it would be nice if it worked off-the-bat.
