post-GNOME 3.8 minimizing problem in Unity

[jaramarana]

I installed GNOME 3.8 from the PPA on my relatively fresh Raring install, and now whenever I minimize a program in Unity it crashes the computer - everything locks up except the mouse and I have to hard-reset.

Does anyone know what might have caused this? The default system font and icons have all changed to the GNOME defaults as well, which I wasn't expecting; maybe that has something to do with it.

Hi, could you post the content of your .xsessions-errors file located in your home directory.

+ This is something you should try (reset Unity):

sudo apt-get install dconf-tools

dconf reset -f /org/compiz/

setsid unity

The Unity reset hasn't worked, unfortunately. Nor has using ppa-purge to go back to the ordinary repo packages.

Here's how .xsession-errors looks:

I just down-graded from Gnome 3.8 to 3.6 and the ppa purge did not down-grade nautilus. I had to force re-installation of the old version and once done I was able remove the rest of the packages and re install 3.6 .
