KMS & Mobility Radeon X1400 (LifeBook N6410): black console on internal display

Hello All,

The system is a Fujitsu-Siemens LifeBook N6410 with on-board
ATI Mobility Radeon X1400.

Testing with vanilla linux-2.6.32 and
libdrm, Mesa, xf86-video-ati all from git (2009-12-15).

I've blacklisted both 'radeon' and 'radeonfb' in /etc/modprobe.d/blacklist.conf
to prevent problems at boot, also I've removed any 'vga=' in
the bootloader (GRUB) configuration.

As root, logged in the first virtual console:
#modprobe radeon

Puff! The internal display turns completely black but...
After several reboots with the tree-finger-salute,
I've come to realize that the system wasn't in hang and thought
about connecting an external monitor to the VGA connector on the back,
just before the modprobe command...
Surprise! That worked and I got a nice 160x64 console.

The next thing I've tryied is a plain 'startx' (no modprobe in advance).
That seems to trigger the 'radeon' autoloading, the X11 server
starts 1440x900 but when I ctl+alt+f1...f6,
I'll stare at a black internal display.

Some interesting lines from syslog:

The problem is the video bios on your card has the same ddc line
specified for both LVDS and VGA so they get combined as the same
connector. The attached patch should fix the issue. Can you confirm?
Can you also send me a copy of your video bios?

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

The next thing I've tryied is a plain 'startx' (no modprobe in advance).
That seems to trigger the 'radeon' autoloading, the X11 server

I'll stare at a black internal display.

What part got rejected? Can you send me the radeon_atombios.c.rej?
Another alternative is to download the drm-radeon-testing branch:

and apply the patch to that.

Hi Alex,
Here's the rejected hunk vs. vanilla linux-2.6.32 tree.

Looks like pretty much the whole patch.

Could you confirm the correct 'git' command?
git clone git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git

yes:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git
cd drm-2.6
git checkout -b drm-radeon-testing origin/drm-radeon-testing

Alex

Cheers,

Eureka! That branch with your patch works great.
I get a 180x56 console, transition between X11 and console
is flawless and takes no noticeable time.
Do you need me to collect any info from the system?
Many thanks for your help, Alex!

Great. Dave should pick up the patch and it will show up in the next kernel.
