Ok so I have posted a couple of threads on here about the problems with graphics on my PC.
Its a AMD 7750 64 bit powered machine, 4gb of mem, 1x500gb HD(which ubuntu runs off as it wouldnt install onto the windows drive) 1x160gb HD and now I am running 2x Radeon HD4670 graphics cards.
Windows 7 (32bit even though this machine is 64 bit due to install problems)is fine with the dual card setup and is working lovely however my 64bit ubuntu is having none of it.
I have run through various versions of ubuntu all with the same result of not being able to use the full graphics potential of this machine. I started with ubuntu 9.04, then 9.10,10.04LTS 64bit, 10.10 64bit and now I am running 11.04 with only minor improvement.
Basically the standard graphics drivers seem to now be working so it boots up without crashing everytime, but under the update manager it says there is an ATi graphics driver to install but when I click to install it I get a new window appear that says:
'The package system is broken' 'If you are using third party repositories then disable them, since they are a common source of problems. Now run the following command in a terminal: apt-get install -f'
The following packages have unmet dependencies:
fglrx-amdcccle: Depends: fglrx but it is not installed
Depends: libqtcore4 (>= 4:4.5.3) but 4:4.7.2-0ubuntu6.1 is installed
Depends: libqtgui4 (>= 4:4.5.3) but 4:4.7.2-0ubuntu6.1 is installed
So then I go into terminal and type 'sudo apt-get install -f' which gives me this:

The following extra packages will be installed:

Unpacking fglrx (from .../fglrx_2%3a8.840-0ubuntu4_amd64.deb) ...
[Warning] Uninstall : inst_path_default or inst_path_override
does not exist in /etc/ati. This suggests that the ATI driver
is not installed, the ATI driver is only partially installed,
or the current ATI driver installed is an older version than the
one this script was designed for. Both files listed above are
required for determining where installed files are located.
To force uninstallation of the driver by guessing where the
uninstallation files are located, set the FORCE_ATI_UNINSTALL
environment variable and re-run /usr/share/ati/fglrx-uninstall.sh (this is not recommended).

I have followed the ubuntu wiki page on trouble with graphics drivers and purging the system of them and starting again but something still seems to be up and I dont know what to look at next
If anyone knows of what I can do I would appreciate the help. I wanted Linux on my machine as a bit of a test for me to get it to work and beat windows, but I find myself banging my head against the wall!
