Elementary OS - Loki
ElementaryOS is a wonderfull Distro. I'm using it because it has the best workspace shortcuts have ever seen.
The Freya version worked out of the box, but unfortunatly the new Loki has som strange "bugs". Whenever i start my computer i have to wait several minutes for the desktop to show up.
The solution is either to move the at-spi-dbus-bus.desktop to /etc/xdg/autostart/at-spi-dbus-bus.disabled
sudo mv /etc/xdg/autostart/at-spi-dbus-bus.desktop /etc/xdg/autostart/at-spi-dbus-bus.disabled
Press Alt+F1 when the problem apears. Login and restart lightdm with:
sudo service lightdm restart
