Fedora 17 troubles

Again... After some time, that  I've spend without any troubles with Ubuntu 12.06, I've decided to upgrade to 'more stable' 12.10. This was my mistake.  It is much more worse in real life then 12.06.
At first glance, it looks nifty, but Gnome 3 still looks like a cheap Chinese imitation of Mac OSX. But in Mac OSX, everything looks perfect! Every pixel or every icon is perfect! Gnome still looks like amateur's work... More worse, every time,  I've got  a lots of strange errors about calendar or something else, that I've never used. After upgrading to kernel 3.5.0.18, I can't even login to my system with NVidia driver without 'nouveau' support at all... I even can't switch to new terminal by Alt+Ctrl+F... !  That's all. I've decided to switch to Fedora again. Though.. Here are some troubles also... But with some help from Mr.Google, I've found some useful solutions.

Fedora 13 troubles

Don't know, why I've decided to install new Fedora 13, after being almost satisfied with my previous Fedora 11 desktop... I already became accustomed to disable SELinux and firewall for decreasing headache while installing specific software. But in F13 it isn't so easy now.
Any way, googling may help and in this case, though...
