Description Bryce Harrington 2009-02-19 14:25:52 UTC 
Created attachment 23121 [details] [review]
Xorg.0.log from an earlier -ati version.  More recent -ati's give the same errors

[Problem]
X gets confused by the presence of two primary graphics devices, resulting in "no screens found" and X exiting.  It also gives this warning:

  (!!) More than one possible primary device found

This issue was first seen in Intrepid (6.9.0+git) but is also still being seen in Jaunty.  It is seen with a variety of drivers including radeonhd (see fdo bug #19513), and it seems to crap out before the driver starts printing its messages, so might rather be an xserver issue, but filing here against -ati just in case.

[Original Report]
The specs:
Asus x56tr Notebook
AMD TURION X2 64
ATI 3200 & ATI HD3470
RAM 4GB

I can install Intrepid Ibex, but my graphics cards don't work in Intrepid.

Installing Ubuntu only works with the extra boot options acpi=off or MAXCPUS=1. Ubuntu Intrepid installed, but i couldn't get any GUI. The x-server tried to start but failed. I also cannot switch to terminal using crtl-alt F1, because X keeps trying. sometimes i get the error message: no screens found. I tried ati, radeon, vesa, radeonhd. I tried installing the official ati-drivers. Nothing worked, then after hours of mindbreaking i installed Hardy Heron, IT worked! Installed the restricted drivers and the screen looks nice. No sound though and no wireless.

How can i get Intrepid Ibex to work? I read somewhere that xorg 7.4 could be the problem or the 4GB of RAM. Don't know how to fix this though. Latest versions of Mandriva and OpenSuse also do not run from livecd or install and suse complains about the graphic card.

Does it work if you specify the busid of one of the cards in your config?

this is a dupe of #18321.
