[Lucid] radeonhd driver does not work with a monitor section in xorg.conf

[Ben Blout]

Binary package hint: xserver-xorg-video-radeonhd

The Radeon card in my machine does not detect EDID information from my monitor, so I need to use a Monitor section in xorg.conf to set a modeline for the monitor. When I do so, the radeonhd driver disconnects the VGA output. (See the xorg log.) Thus I can not use the radeonhd driver with this setup.

The radeon driver works fine with the same hardware, and the same xorg.conf file.

Attached is my xorg.conf file

Here is the xorg log, when I use the radeonhd driver

The key lines in the xorg log are near the bottom, I suspect:
(II) RADEONHD(0): Output VGA_1 using monitor section Sony
(II) RADEONHD(0): Output VGA_1 has no monitor section
(II) RADEONHD(0): Output DVI-D_1 has no monitor section
(II) RADEONHD(0): EDID for output VGA_1
(II) RADEONHD(0): EDID for output DVI-D_1
(II) RADEONHD(0): Output VGA_1 disconnected
(II) RADEONHD(0): Output DVI-D_1 disconnected
(WW) RADEONHD(0): No outputs definitely connected, trying again

Then there is a bit of a backtrace at the end, of course.

If I change one line in my xorg.conf file, so that I use the radeon driver instead of the radeonhd driver, then X starts and runs normally.

In particular, I change
        Driver "radeonhd"
to
        Driver "radeon"

I am attaching the (working) xorg log that results from using the radeon driver

Is this the right location (package) for this to be filed agains?

Separately, I could go upstream with it, if that is appropriate, but I would like some one with more
knowledge to tell me it is not a Ubuntu-specific

radeonhd doesn't work with lucid because kernel modesetting is used, and radeonhd doesn't support it. Closing as wontfix. The driver will likely be removed from lucid. As you noticed, -ati works and supports all the chips out there.. (though maybe not the newest ones just yet :)
