Public bug reported:
Since last night's updates, automatically logging in with LightDM causes
the screen to be blank with only a cursor shown. The desktop does appear
to be rendered on the background, because moving icons and clicking
menus (after guessing where they are) does work. The only way to get
things normal again is by restarting the lightdm service. I haven't
(yet) noticed anything weird when manually logging in.
It doesn't seem to happen every time, but it does happen a lot. I have
also noticed that when it does seem to work normally, the dmesg output
on tty7 sometimes blends in with the desktop; for instance, a black box
with a blinking cursor is shown, or when plugging in a USB thumb drive,
the output from 'mount' will be displayed, until I move my cursor over
that area.
I'm running fully up-to-date Xubuntu 12.10 (no proposed packages though)
on a laptop with Intel graphics (xserver-xorg-video-intel driver).
P.S. When LightDM was updated, the X server was updated as well, so that
might also be what causes this.
