Ubuntu 12.04 - mining with GTX 660 ti and AMD 7770

Hello.

So I have recently started mining bitcoins. I have my own custom built PC with dual boot Windows 7 and Ubuntu 12.04.

I had previously purchased an Nvidia 660 Ti as a gaming GPU upgrade from my old GTS 250. Which is fine, but when I started bitcoin mining with it, it was only giving me ~98 Mhash/s, which is alright, but not too great.

So today, I made a purchase of a ATI 7770. I have been able to mine off both my Nvidia and ATI card on Windows 7 fine with GUIminer, (the 770 adds a nice 185 Mhash/s to what I was previously doing.

However, when it comes to configuring it for Linux, I start to have some problems as Ubuntu is having problems detecting the card (even with ATI drivers installed)

I have aticonfig detecting the ataptor

aticonfig --list-adapters
* 0. 02:00.0 AMD Radeon HD 7700 Series

* - Default adapter

but otherwise, I cannot seem to get it working as an actual option (it seems to not like my xorg.conf file).

Some form of help would be appreciated, I have done some reading around and I *know* it is possible, but no luck yet.

however, lspci seems to pick up the devices existence, but I cannot get the device to be detected by any of the miners under Ubuntu

01:00.0 VGA compatible controller: NVIDIA Corporation Device 1183 (rev a1)
01:00.1 Audio device: NVIDIA Corporation Device 0e0a (rev a1)
02:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 683d
02:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Device aab0

The reason why I would like it working under Linux is that I happen to do a alot of work under a Linux enviroment (LaTeX and programming etc). So having my GPU's mine is a nice use of resources whilst I am working on something.
