Created attachment 100656 [details] Xorg.log I get the message "No devices detected" in Xorg.log if I try to use my PciE GeForce GT 610. The device seems to be initialized correctly in the kernel module but Xorg refuses to use it. output from lspci | grep VGA: 01:00.0 VGA compatible controller: NVIDIA Corporation G96 [GeForce 9500 GT] (rev a1) 06:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1) The other graphics card is my main graphics card. If I configure both cars in xorg.conf only the main card is used. If I only configure the GT 610, nothing is displayed.
Created attachment 100657 [details] output from dmesg Ouput from dmesg added.
Created attachment 100658 [details] Xorg.conf with both cards configured Xorg.conf where both cards are configured. Only the primary card is started. Xorg.log is from another config.
Created attachment 100659 [details] Xorg.conf for only the secondary card This is the xorg.conf where only the secondary card is configured. In this mode only a blank screen is shown. The xorg.log is from this configuration.
Should be fixed with commit adbbdbac04f093c0abf946b1e93e4e5291808491 Author: Dave Airlie <airlied@redhat.com> Date: Wed Mar 26 14:09:37 2014 +1000 drm/nouveau: fail runtime pm properly. If we were on a non-optimus device, we'd return -EINVAL, this would lead to the over engineered runtime pm system to go into an error state, subsequent get_sync's would fail, so we'd never be able to open the device again. (like really get_sync shouldn't fail if the device isn't powered down). Signed-off-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> which went in 3.14.0-rc8. Feel free to forward it to stable if it resolves the problem for you.
