I have just joined this list so I thought I'd say a little about why.
I enjoy using Linux and I look forward to sharing ideas about it with
like-minded people. I live in Wellington, Somerset, which is a long
way from Bristol but it doesn't matter because I don't drive now (age,
eyesight,etc) so I would not be able to get to meetings. I belonged to
the Glastonbury list once and occasionally went to meetings there.
There is no group in Taunton that I know of.
I first met Unix in 1984 and I've experimented with several distros
but I have fixed on Debian now. I have a PC running Squeeze and another
running Wheezy. I have just today installed the rolling Debian Mint to
try out.
Other interests: I use TeX (but sometimes LibreOffice is easier) and
MySQL. I can write in C and Python. I have created a couple of web sites
using HTML.
I don't have any problems right now but I'm sure I'll think of one soon.

No there doesn't seem to be one for Taunton, however there's a Devon and
Cornwall LUG, and it seems there may even be one for Exeter.
As for the Bristol and Bath Linux User Group meetings are at a pub
rather close to the Temple Meads train station in Bristol.

Ok although this list can also be used for general Linux/tech related
things etc as well.

Hi all,
Does anyone want some 2006-2010 era computer hardware? I have just
bought a new desktop and am trying not to accumulate piles of hardware
"just in case" (as I have been guilty of before).
I am offering this stuff up here before I take it for ewaste recycling.
I have available:
* ATX case with 80mm and 120mm case fans.
* ATX 450W PSU
* Winfast (Foxconn) socket AM2 motherboard with AMD X2 64 5000+ CPU and
4GB DDR2 RAM
* Variety of PCI cards (wired/wireless NICs, 56K modem, USB 2.0 hub etc)
* 256MB DDR DIMM and SODIMM.
* A few old AMD CPUs for various sockets and with various ratings.
The case is in good condition, bought about 2 years ago from Maplin. I
can't guarantee anything will be in 100% working order, though most
parts have been used recently and work okay. I do believe the
motherboard / PSU / RAM combination to be somewhat flakey, but do not
have the time or inclination to determine which of these is the problem.
Contact me off-list if you are interested in rehoming any of this, or
want further details.
Regards,
James

Hi again,
I muddled my way through the MBR/BIOS --> GPT/UEFI conversion process
for my Ubuntu install today. It went surprisingly smoothly!
For anyone else who might want to do this in future, I thought I might
update you on how it went.
The steps I wrote in my last e-mail were generally correct in my case. A
few extra details are relevant, though:
(i) The EFI FAT32 partition should be set to partition type code EF00
using gdisk (similar interface to fdisk) when converting from MBR to GPT
partition table.
(ii) Before running grub-install in the chrooted root partition, you
need to mount some system partitions inside that chrooted partition,
e.g. before issuing chroot /mnt (where you have mounted your root
partition), issue
for i in /dev /dev/pts /sys /run /proc; do mount -B $i /mnt$i; done
(iii) Before running grub-install in the chrooted root partition, the
FAT32 EFI partition should also be mounted at /boot/efi inside the
chrooted root partition, so the program can correctly install the efi
bootloader
Additionally, it is worth noting that installing Ubuntu's grub-efi
package inside the chrooted partition removed the grub-pc package (for
MBR type grub installation).
Finally, it took me a while to remember I had to disable the secure boot
option in my BIOS before Ubuntu would boot!
These resources were useful:

Hope this is useful/interesting,
James
