I recently installed an AMD Radeon HD 7850 into my desktop, which had previously been running on Intel integrated graphics. Once I made the switch, X began failing to start. Xorg.0.log indicated that the ati and radeon xf86 modules were successfully loaded, and additionally indicated that udev had found a PCI graphics card with BusID PCI:1:0:0 and bound it to /dev/dri/card0. Then the process failed with (loosly) the messages: (EE) No devices found ... (EE) No screens found Adding a minimal xorg.conf (attached) that simply specifies the BusID of the card as reported earlier in the Xorg log resolved the issue and allowed X to start with the Radeon. Previously, I had no xorg.conf, and was relying on autoconfiguration. Unfortunately, the successful startup wiped out the logs of the failing Xorg processes. I am under the impression that X should be capable of autodetecting the card, given that it is identified in the Xorg log.
Without at least xorg log of such failed start, this is more of a rant, than a bug report. Also, in my experience, such minimal xorg.conf shouldn't be necessary (well, not unless it's ppc hardware - a few forum posts suggest in that case it might be). Again, without the log - no go.
1) Please post your `emerge --info' output in a comment. 2) Please post your `emerge -vpq x11-drivers/xf86-video-ati' output in a comment. 3) Please attach the relevant Xorg.?.log to this bug report.

That's much better. One other thing - kernel config file ?
Please attach kernel .config and dmesg, thank you in advance.
Created attachment 352038 [details] Kernel .config in use
dmesg output in general, or specifically when the X server fails to start?
Possibly it is a case of missing PCI id in the driver. You could try with latest xf86-video-ati from git, you can find a live ebuild in the x11 overlay.
There's not really anything Gentoo developers can do to solve this. Please file a bug upstream https://bugs.freedesktop.org/enter_bug.cgi?product=DRI if the problem persists.
