Description Mike Burns 2010-02-08 10:57:55 UTC 
Linux 2.6.33-rc7 using KMS, xf86-video-ati from git.

ATI Technologies Inc Mobility Radeon HD 3650, Apple 30", Thinkpad T500.

The Thinkpad has a DisplayPort on it; the monitor is DVI; using a DP->DVI converter.

The BIOS and console show on the monitor, but X doesn't. xrandr says:

 DisplayPort-0 disconnected (normal left inverted right x axis y axis)

Unsure how to proceeed from here; #radeon suggested I file a bug report since this should work.

Xorg.log

My fault; I thought I had attached it before but I didn't double-check.

Is there anything else I can do to assist this ticket? Patches to try, git branches to compile, etc?

You are mixing a KMS drm with UMS in the ddx.  Make sure the radeon drm is loaded before you start X otherwise both drivers (drm and ddx) will attempt to drive the hardware.

Alex, that tip fixed it. Thank you.

I added `radeon' to /etc/modules and it now works.
