Ubuntu 9.10 and Bluetooth audio.

Ubuntu 9.10 splash screenFollowing the release of the new 9.10 ‘Karmic Koala’ version of Ubuntu, we installed it on one of the Asus 901s, trying out a new configuration of all ext4 disk partitions and no swap partition. Discovering that the ‘Netbook Remix’ (UNR) release of the operating system now could only use the mobile phone look-alike interface and had the Desktop-Switcher package removed, we followed forum advice and tried the full Ubuntu 9.10 release instead. Having disabled the ‘wobbly windows’ graphics enhancements in Gnome, Ubuntu 9.10 was no trouble on the Asus 901 – all the devices worked from the start, dialogue and menu boxes fitted in the available screen area by default. One of the main reasons for trying Ubuntu 9.10 was to experiment with an early desire of ERA to use the bluetooth audio headsets commonly available for mobile phones instead of wired mic-and-headphones devices. With our Ubuntu 9.04 UNR installations we couldn’t get this to work, despite spending a frustrating day or two in early July with the latest software then available. At that time, improved bluetooth interaction with beta Pulseaudio releases and experimental device control with Blueman were not integrated into Ubuntu releases, but promised to make bluetooth audio as simple under Ubuntu as it is on a mobile phone.

At the end of last week we managed to create an IAX to IAX trunk between 2 asterisk servers on the local wired LAN. IAX trunking is a way to connect multiple Asterisk servers and allow clients of different servers to place calls to each other. Continue reading

Disk Imaging with Clonezilla.

CloneZilla!

CloneZilla!

Once our netbooks have their operating systems and software installed on them, when they’ve been tested and tinkered with, it’d be a shame to have to do all that again without good reason. To avoid wasting time in the future, it makes sense to back-up the whole system whilst it’s nice and tidy, so if there are problems later we can roll back to a ‘known good’ installation quickly. There are several packages for doing this – Norton Ghost and Ghost-4-Unix are well known, but a slightly obscure project from the Taiwanese National Centre for High-performance Computing called Clonezilla beats them all on either price or performance, or both.

UNR, revisited.

One of our netbooks needed rebuilding recently, and since we’ve not documented the installation procedure we used, now seems like a good time. We’ve been running our Asus EEE 901s on Ubuntu Netbook Remix 9.04 (UNR), since the supplied Xandros is a little unfamiliar and limited for our needs. It’s mostly like normal Gnome-based Ubuntu except that it fixes some issues specific to netbooks, e.g. the small screen. There are similar distributions available – EasyPeasy and Moblin for instance, but we’ve been using UNR. Continue reading
