since changing the http_proxy, https_proxy and ftp_proxy environment variables didn’t work out with me, I had to search and find another way, and it worked flawlessly:
1- Add a new file with name “80proxy” to “/etc/apt/apt.conf.d”, e.g. “vi /etc/apt/apt.conf.d/80proxy”
2- Add the following lines:
Acquire::http::proxy “http://<proxy>:<port>/”;
Acquire::ftp::proxy “ftp://<proxy>:<port>/”;
Acquire::https::proxy “https://<proxy>:<port>/”;
3- That’s it, now I’m a happy apt-get user :))
You have to do “sudo apt-get install libreoffice libreoffice-gnome”
The trick here is the libreoffice-gnome, which will integrate properly with Gnome (since LibreOffice windows weren’t showing up in the botton bar) and enhance the GUI significantly.

PDF printer comes by detault in linux mint, and when I tried it, it produced blank pages with no content whatsoever.
What I did to fix this is that:

I was having terrible tearing while playing any videos on my Ubuntu Oneiric 32-bit with Gnome 3 on my new Thinkpad T420 laptop with Intel SandyBridge Graphics Card.
I have googled around a bit, and found this only solution, haven’t investigated much behind it, but gave it a try, as I could easily revert it back.
I just added these two lines
CLUTTER_PAINT=disable-clipped-redraws:disable-culling
CLUTTER_VBLANK=True
to my “/etc/environment” file, then restarted, and surprisingly it worked out!! No more tearing whatsoever in any videos I play!
Enjoy!
Update: This also solved the video tearing issue on Precise with Gnome 3.4

If you’re getting really annoyed – like I do – whenever you’re typing something and you touch the touchpad by mistake, which transfer the cursor to some other window on the screen, then this article is what you’re looking for:
Open a terminal and type in:
synclient MaxTapTime=0
If this successfully disables the tap to click, then add a new startup entry (Settings->Settings Manager->Session and Startup->Application Autostart) where the command is:
bash -c “synclient MaxTapTime=0”
