I tried Xgl today - and whist it looks nice and supports my twinview setup (shocking!) I coudn't get on with it. The reason I couldn't get on with is it because you need to replace kwin with something else, as kwin doesn't have support for it yet.

So... I went onto #kde and asked if there was going to be support for it in KDE4, apparently there will be, but this answer isn't offical. Some kind person (PhilRod) pointed me to a digest , which in turn pointed me to the KDE svn repos showing commits to kwin that appear to be relevent. I'll try to figure out who lunakl is, and ask him for an offical answer.

Update: Having mailed lunakl (Lobus Lunak) he pointed me to an article on On KWin wobbling and such stuff over on kdedevlopers.org. As it turns out, KDE is in need of graphics developers, and this was dgged about last month. So, it's planned... but some code monkeys with ubergraphical skills are needed.

Yes, it's possible. You can even use it for webcam chat under Kopete IM (and other probably).

Firstly, the camera doens't present itself as a v4l (video 4 linux) device, so you need vloopback kernel module. This kernel module will create 2 v4l devices, usually /dev/video0 (input) and /dev/video1 (output).

You'll want to install coriander and libdc1394, probably the latest versions.

Plug your camera in, insert vloopback, and start up coriander. Click 'v4l' button so that coriander will start to export your camera via the vloopback module, and that's it, you can now use your iSight as a v4l device. Fantastic.

I'm far from an expert in this field, so if you have questions about this setup, you're best taking them elsewhere

Update: If you're finding that your colours are messed up and green and purple, you'll need to make a change to the coriander source (effects versions of at least up to coriander-2.0.0-rc1)

Thanks to Marc Roberts who pointed this out to me...

I have fixed the color problem that I had with Coriander. In conversions.c, I changed the enumeration in line 32 from
DC1394_BYTE_ORDER_YUYV to:
DC1394_BYTE_ORDER_UYVY

update: Seems my blog software doesn't allow HTML in the comments, so here are some useful links.

Domi is a tool for building Xen domains. It's usage is covered in HOWTO Xen and Gentoo hosted on the gentoo wiki site. It says you can use it to install Ubuntu, but no where actaully tells you how. So.. here's how!

# cat ./ubuntu.cfg
DOMI_XEN_CONF="/etc/xen/test"
DOMI_XEN_KERNEL="/boot/vmlinuz-2.6.16.18-xenU"
DEBIAN_MIRROR="ftp://ftp.ubuntu.com/ubuntu/"
DEBIAN_RELEASE="dapper"
DOMI_DISTRO="debian"
DOMI_NAME="test"
DOMI_VDISK="hda"

Yes, I do know the DOMI_DISTRO is set to debian, but ubuntu is based on the debian package manager, so that's correct.

Note that you have to setup the /etc/hostname and /etc/hosts after.
