How to fix the blank screen on clutterview problem on ubuntu 10.10 maverick meerkat
And here's the contents of the link in case it goes down:
Couple of days ago I installed “Nautilus Elementary” on my Ubuntu maverick meerkat. Strangely I was not able to enable clutterview. When I pressed F4 it just showed a black blank screen and that was real annoying. A few considerable search on google showed me the way to fix this, a comment on webupd8.com.
The problem is linked to a vblank issue which occurres in combination with Intel GFX cards and clutter services. To fix this edit /etc/environment by issuing the command:
sudo gedit /etc/environment
and add the line
Save it and reboot your system. Clutterview should work like a charm now.
