tarball of logs etc

when i boot with kms enabled my secondary display only shows stuff till kms kicks in
i cannot get anything to output to it after x has started either
both displays works fine without kms

my graphics card has 3 outputs (one i assume is svid and 2 dvi )

xrandr shows 4 with 3 connected

attached dmesg, xrandr -q and xorg.log with and without kms

You need to load fbcon to have the console use the framebuffer device provided by the drm.  Also, in the future, please attach files individually.  Make sure you are using the latest code from drm-next.

ive done some more poking-round and it is the plug intended for use with the hdmi adapter that is incorrectly detected with kms
Comment 4 aaron 2009-10-12 19:27:52 UTC
... and if i use a dvi -> vga adapter on that plug (and hook it up to my screen via a vga cable it works but looks less crisp than the other display ( ie a bit "fuzzy")

i also noticed that a few asus cards dont report things correctly - its an asus EAH4870 DK

what connectors does your card actually have?  According to the driver it has:
- DIN (tv-out plug)
- HDMI
- VGA
- DVI

If it has different connectors let me know and we can add a quirk for your board.  Can you also attach your video bios?

As root:
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom 

and finally, can you attach the output of lspci -vn?
Comment 6 Alex Deucher 2009-10-15 14:29:03 UTC
might be that your monitor doesn't like coherent mode.  I'm not sure there is a way to adjust that via kms yet.
Comment 7 aaron 2009-10-15 23:43:09 UTC
either screens work when plugged in to to the "working" dvi plug but i dont know what coherent mode does...

The card has 2 dvi and 1 din

  Will attach other stuff later
