Nvidia drivers & related software (nvidia configurators) change settings for Intel drivers. And so tell the xorg-intel
driver the wrong info. For all NONE-Nvidia PCs, easy to fix: If you have "simple-ccsm" (Simple Compizconfig settings manager) installed: (if not install "ccsm" or "compizconfig-settings-manager") 1st right-click on your PC Desktop, use <Tab> to select, left-click on "Change Desktop Background". Use <Tab> again & select "Visual Effects" tab, use <Tab> key once again & select "None". (Upside down & mirrored is difficult to read or select by mouse. <Tab> will indicate where you are in a menu). The Desktop will right itself. Then use "Synaptic Package Manager" (or the Terminal, for those who know how) & purge all Nvidia programs, refresh (apt-get update), & it may be a good idea to reinstall your particular Video card software which will set configuration back to where it should have been. Then restart "compiz" & select your level of Visual Effects. Problem solved! Perhaps the Ubuntu Masters may build a fail-save, so that wrong video info can not corrupt configs.
