Debian Radeon X1600 KMS (MacBookPro2,1)

[robin1979]

Hi guys,

I'm trying to get KMS working on Debian (unstable), but I can't get it past the first steps.

I'm using the 'linux-image-2.6.32-trunk-amd64 (2.6.32-5)' kernel (which is based on 2.6.32.3), and as soon as I 'modprobe radeon modeset=1' the system hardlocks (LCD panel switches off).

Package 'firmware-linux-nonfree' is installed.

Any ideas anyone? Anyone experienced something similar?

Thanks,
Robin

Does it work any better with a newer kernel or drm-radeon-testing?

KMS is working fine with my Macbook Pro1,1 X1600 running Debian unstable and custom kernel. Currrently I'm running 2.6.33-rc7 with modesetting compiled inline and enabled by default

Firmware for R520 is built into kernel. There is no need for external firmware as is the case with R600.

My kernel config:

Ah... my config will not work for you as Macbook Pro2,1 is Core2. I only have a lowly 32-bit machine. :-)

The important part is the kernel version.

The important part is the kernel version.

I've had KMS working fine since 2.6.32 on my Macbook Pro. I wonder if X was running when robin1979 enabled KMS. I've always had KMS enabled prior to starting X. Also, is fb console inserted as well when enabling modesetting via module?

No, X wasn't running. I even removed X from the boot and did a fresh boot so to make sure X hadn't messed up some registers.

I'll double check the fbcon module (fbcon.ko isn't it?).


I'll try a custom (newer) kernel if I have to. Was hoping to get it working out-of-the-box .

Can you ssh to your laptop after enabling KMS? Or is it totally borked?

For what it is worth here are the salient parts of dmesg on my laptop:

It hardlocks, can't SSH to it anymore. Doesn't even reply to ping.

Another possibility might be a loaded module KMS does not play nice with. vesafb?
