I've installed bumblebee at my laptop due to the 520M GPU following the steps mentioned here.

What I see after logging out and in is this.

But I've noticed now that I do have some effects I didn't have, in example the windows open with a bounce effect (if we can call it that way) and the alt+tab feature shows now the screenshots of the windows.

What can I do?

Here's the link to pastebin with contents of xorg.0.log.

I see that optirun does not work for you. The Troubleshooting article mentions a solution for an error in your /var/log/Xorg.8.log: edit /etc/bumblebee/xorg.conf.nvidia and change DFP to CRT-0.

I've downloaded the acpidump for your laptop model and it looks like that the calls in /etc/bumblebee/cardo{n,ff} are correct. To get PM really working, you also need the acpi_call kernel module. You can install it by installing acpi-call-tools from the bumblebee/stable PPA (which you've already enabled):

sudo apt-get install acpi-call-tools

In /etc/bumblebee/bumblebee.conf, change STOP_SERVICE_ON_EXIT=Y to STOP_SERVICE_ON_EXIT=N to allow the card to be disabled after the last optirun instance has been quit. You need to restart the daemon after that change:

sudo /etc/init.d/bumblebee restart

You can try to reset the unity settings by opening a terminal and running unity --reset. If the driver from bublebee doesn't support Unity, then you can use Unity 2D by clicking the button next to the password field before you log in.
