Re: [Hampshire] Ubuntu 12.04 Server Issue

[Mihai Badea]

Hi Sean,

If you managed to boot that means grub can work, no matter what distro you
use. So you should at least be able to boot to grub menu. I have an Ubuntu
12.04 server myself on an ASRock ION 330. Perhaps it was something you
forgot (such as grub not installed in mbr, partition not marked bootable,
hdd order swapped in bios at the time, and with the repartitioning and a
new install it got fixed). Perhaps it was just bad luck?

Re: [Hampshire] Ubuntu Unity

[Mihai Badea]

I reverted to KDE. I have 4.8.5 from Ubuntu 12.10 LTS.
It is stable and fast now, and works fine with or without desktop effects
(while Unity 2D is a disaster!).
I know it was always more been complex, but now it's also very intuitive
and straight-forward at a basic level.
Check-out the option now for taskbar icons (like W7 or Unity). You can
also customize the task switcher for best 2D appearance.

Re: [Hampshire] Raspberry Pi Questions

[Mihai Badea]

I got mine from CPC Farnell for £35 including transparent case (which is
awesome) and delivery.
A few points:
 - only booted once on desktop, then used ssh and vnc only
 - used a cheap class 10 SDCard from a photo camera
 - Raspbian is very easy to use and update, just like a normal Debian but
it only sees 256MB out of the box; to see the whole 512 RAM you need to
download the new /boot files from git
 - use any smartphone charger (750mA+) - gets stuck in bios if plugged in a
USB port such as router or laptop
 - not great as media player, server, router or desktop system; probably
more suitable for DIY projects such as web cat feeder and home security
