Problem with Ubuntu 12.10 64 bit & Ati Radeon 7870

Asked by Massimiliano Maniscalco on 2012-11-13

I use Ubuntu 12.10 64bit desktop versione on my system with Gnome 3 as a default desktop manager. Everything worked well with Intel integrated graphics HD4000, this is my system configuration:
Asus P8Z77-V Pro/Thunderbolt motherboard
Intel i7 3770k
16 Gb Corsair Vengeance

Now I just installed a graphic card Ati Radeon 7870 and I have several issues:
1) if I try to use Ati Catalyst driver nothing work anymore, Gnome 3 doesn't start, it always start as Gnome Classic, Unity doesn't work, no launch bar on the left, no menu bar, I just see the desktop.
2) if I use open source driver performance are very poor, Wine doesn't work anymore.

Should I re-install the system to make it work well?

By the way, should I connect my monitor on the HDMI of the motherboard or on the HDMI of the graphic card? I'm using the HDMI of the graphic card now.

Thank you for your help.

I ever received an alert that Compiz crashed and then it said that I have a 3D accelerated card but is using software rendering instead of hardware...

Seems that problem is about xserver-xorg-intel package, I found a guide on this post

This solved my problem, now I can use my Radeon HD 7870!
