<p>Ok, just to be sure we are on the same issue here. Your issue is that the Unity top bar is still visible?</p><p>A couple of things to try you might try togglnig the X11 bypass again after selecting the option to hide the launcher in your settings if you haven't.</p><p>Also just to be sure your main monitor (laptop screen) is on the left and your external on the right? You might want to try completely booting into Ubuntu then pluggin the monitor up (if you aren't doing it that way), sometimes Intel chipsets can be a little flakey with this and could possibly cause some strange issues, I doubt that will be the problem here but worth a try.</p><p>I still haven't had a chance to test, I am guessing your hardware wont handle Unity 3D? if not and this is a must go for you, in the short term you could install the gnome-fallback-session (i am pretty sure on the package name it will be available in the software center) And log in using gnome fallback I know from experience that this works well and will not install a whole new destkop environment since Unity is build on top of GNOME 3.</p><p> </p>
