K3B No CD/DVD writer found (No detect CD/DVD writer)

[Francesco Duraccio]

Binary package hint: k3b

Ubuntu karmic 9.10

No CD/DVD writer found.
K3b did not find an optical writing device in your system. Thus, you will not be able to burn CDs or DVDs. However, you can still use other K3b features such as audio track extraction, audio transcoding or ISO9660 image creation.

This is the error if i try to launch from shell:

QStringList Solid::Backends::Hal::HalManager::findDeviceByDeviceInterface(const Solid::DeviceInterface::Type&) error: "org.freedesktop.DBus.Error.ServiceUnknown"

Thx.

Rebooting the system fixed it !

[TK (tkrishan)]

I can also confirm that after rebooting, the problem went away.

Running the following command will also fix it without a restart:

sudo service hal restart
