Christopher, My 2017-04-30 report was from standard UbuntuStudio live distro 17.04. Sorry for xdiagnose missing. Since 2017-04-30, I bought a new graphic card Radeon HD 7450 that works fine with UbuntuStudio 17.04 and upgrade to this new version (and got new Kdenlive version that works quite well!). I've just installed xdiagnose and I'll move out this new graphic card to apport new data as soon as possible.
