Here's a small list of things that may need attention.
Sleep button on desktop computer keyboard, if your cat walks across the keyboard and happens to press sleep, this puts the PC into a coma, I have tried everything to revive it, pressing the power button on the computer case give a false hope, keyboard flashes as well as the mouse, possible fix super glue the button.
Still have problems with themes Aurora and all of the TerraNova themes the right click menu in file manager won't stick, well sometimes it does.
If Cairo dock runs at startup and has a weather applet which runs before a network connection is established, it can't find a connection, even refreshing the applet has no effect and x needs restarting for it to work, one fix is to start Cairo dock manually, this maybe one of the reasons it has a menu entry.
fix for cairo-dock to give the network a head start.
/root/Startup, edit cairo-dock
The keyboard suspend is the main problem.
