I'm at my wits end - after trying solid for the past week to get a working display driver on my new hand-built machine, I have had zero success. I've exhausted the forums, trying every possible combination I could find and still have had no luck. Can anyone please provide me with some insight? maybe that one little thing I'm missing? Here's the low down:
I have a Gigabyte Radeon HD 7950 video card running on an intel i5 / z77 motherboard with a clean install of Ubuntu 12.04 64-bit Desktop. Verified hardware as working in Windows. I have tried installing just about every version of the AMD Binary Driver, as I have read repeatedly that the Radeon HD 7000 series cards are not supported by the open source driver. I have tried using the fglrx driver provided by the Ubuntu repository, as well as the amd website *.run files of catalyst driver versions from 12.1 to 12.6. I have also tried compiling the driver and installing exactly as directed by the page
But I still get the same error, regardless of which driver I use. I have also tried the drivers with the boot argument "nomodeset" to no avail. I'm not 100% sure which error is really the culprit of the failure in my Xorg.0.log, the "fglrx: No Matching Device Section for Instance" (note - the hardware @ PCI 1:0:1 it is complaining about is the HDMI Audio Device!?) error, or the "xf86OpenConsole: setpgid failed: Operation not permitted" error. You can see the full log, xorg.conf and lsmod, lspci output at the shared google docs folder below.
Any suggestion at all is appreciated (give up and wait for Ubuntu 12.10? haha). Thanks.
