Summary: [radeonhd] wrong selection of available resolution on
rs690

Bug reported by Cyrille Chépélov on the Debian BTS. Applies to 1.1.0 and git
bc88513. He says:



The radeonhd driver fails to properly enumerate available DVI connectors on my
system and assign them proper resolutions.

The video card is an integrated RS690 on an ASUS V2M motherboard. There is a
VGA and a DVI connector. The DVI connector is connected to the DVI connector of
the monitor through a single generic cable.

The driver reports two DVI connectors, one able to run up to 1280x800 and
connected to the monitor, the other able to run up to 1280x1024 (the actual
native resolution of the monitor)

RandR utilities see a similar report, grandr crashes when attempting to
interact with the phantom second DVI connector.

Once X starts with GPM, the card is initialized with a strange combination of
1280x800 and 1280x1024 resolutions: the X logical screen is 1280x800, while the
monitor and physical display areas are initialized to 1280x1024. Pixels are
reported square to applications. The mouse is free to roam all the way down to
the 1024th line.
Once the GNOME session starts, the top of the screen is replicated below the
800th line, and the mouse is free to roam on both parts. The GNOME-RandR applet
shows only a few resolutions from 640x480 to 1024x800; selecting one actually
changes the video mode to what's being shown in the RandR applet.

PS: I do not have an available VGA cable around, and would like to avoid this
extremity.
