Xorg.0.log - Driver "fglrx"

Adding myself to the CC list. I'm also running a Sapphire HD 4850 X2 and encountering the same problems.

Using the "ati", "radeon", and "radeonhd" drivers results in "no screens detected". Using the proprietary "fglrx" driver results in the console hard locking with either a black screen or a corrupted screen, and attempting to switch between virtual terminals doesn't work. You can, however, SSH in just fine to make changes, reboot, etc.

I've attached my "lspci -vvnn" output as well as the Xorg.0.log from each of the four drivers. (ati, radeon, radeonhd, fglrx)

Good luck and let me know if you need anything else.

added the pci id:
15ee78d37f8b64c3e6d234e7ab37a31e82327b6b

Thanks Alex, I'll compile in a short while and post the results.

Xorg.0.log - Driver "ati" PATCHED

It looks like the changes have fixed this bug. X now properly recognizes the 4850 X2 as can be seen in the Xorg.0.log I've attached. However, X still fails to work properly and the result is now the same as the "fglrx" driver. Running "startx" works but the screen goes black and you are unable to switch virtual terminals, use ctrl+alt+backspace, etc. You can still log in remotely and work though. I'll be filing a new bug report for this.

Thanks again Alex.

Does adding this to the device section of your config fix it?
BusID		"PCI:4:0:0"

Alex, try: BusID "PCI:3:0:0"
See my Xorg Log for details.

You'll need drm support.  Make sure you are using 2.6.30 or a properly patched drm.  You may also need to add the pci id to the drm if it's not already there.

That option may not be relevant for you, it was directed at Cody.  The pci bus ids depend how your system.

I got it working now, the system I was testing it on was running Fedora 10 and I think there was a conflict with having ATI's fglrx driver installed concurrently.

Currently I have it working perfectly on an Arch install running KDE.
