Comment 3 for bug 1066410

I am disappointed I can't close the bug. The problem still persists. The reinstallation of lightdm package affected only first 3 boots after the procedure, but it no longer seems to make any effect.
In addition, I've noticed that my mouse pointer is not only visible on virtual terminal 7, but also on every other terminals. How could that be so? However, I can't use the mouse on vt1 through 6.

I now assume everything works correctly except the fact I can't see anything (only a cursor) and the cursor is visible on all virtual terminals independently.

I can login in lightdm even though I don't see anything, even after unity loads. (lightdm, xorg, compiz - those all works, but for some reason I've got almost blank screen on vt7).

To get my screen working I have to either kill lightdm and then start it again, or login through lightdm I don't see and then kill the gnome-session.
