I found Ubuntu Hardy and Mint Elyssa have a lot of common problems from sound to scanning, and seems like you guys need to work out a bit to make them more stable. So far I had to remove pulseaudio to get back my sound, identify problems in font hinting of terminal and firefox browser and still have trouble with sane backends that completely missed out my scanning device. The package controller shows that the libsane has already installed but Kooka and Xsane cannot recognise this device. Kooka stated that: "No scanner was found: your system does not provide a sane installation, which is required by the KDE scan support. Please install and configure SANE correctly on your system".
Anybody has advice on this bug?
