Dual Monitor problem on HD3450/RS780/RS690

[Blue Beard]

Since radeonhd 1.2.4 (including the upgrade 1.2.4-1) came to jaunty Alpha 4 the outputs of my HD3450 became locked together with any xrandr command. See example below. I have two motherboards one with RS690 and the other with RS780. I switched between radeon and radeonhd. Both motherboards and drivers produce similar results.

Currently my xorg.cong is stipped with only a virtual subsection being added to allow the monitor to be moved out of the default 1360x1360 area.

What direction should I concentrate my research effort to solve this problem? a) expanded xorg.conf, b) use extended R6xx code, c) x.org git driver.

Suggestions?

I have heard a few people mention similar problems recently.

Since radeon and radeonhd have fairly different modesetting code if both of them suddenly broke then it sounds more like xserver than driver.

Why x-server related?

The major change between working and not working may be related to OPTION "HPD" "off" which is now depeciated.

X-server went from rc1 to rc2
kernel from 2.6.28-4 to 2.6.28-8
radeonhd from 1.2.4 to 1.2.4-1

The last time both monitors worked:
2.6.28-4-generic #11-Ubuntu SMP Fri Jan 16 21:50:52 UTC 2009 x86_64

Fixed - almost

I did a fresh install of jaunty alpha 5 and went thru the python problems
x-server 1.5.99.902-7
libxrandr 1.2.99.4-2

The radeon driver (6.11.0-2) now ignores my second monitor.

The radeonhd driver (1.2.4-2) not only fixes the problem, the sharpness of my LCD monitor has improved significantly.

The screens are now swapped (i.e. right-of produces left-of). In the past this was fixed by OPTION "HPD" "off"

Please file bugs (https://bugs.freedesktop.org) and attach your xorg logs and configs.

Fixed - again

See Bug report 20407 for more details.

x-server 1.6.0
libxrandr 1.2.99.4-2
radeonhd 1.2.4-2

The radeon driver (6.11.0-5) still ignores my second monitor.

Using radeonhd driver and OPTION "HPD" "off", DVI-D_1 now appears.

Fixed - Best results with

x-server 2:1.6.0-0ubuntu1
libxrandr 2:1.2.99.4-2
radeonhd 1.2.4+git2009031

I get the best results with

Section "Device"
Identifier "HD3450"
Driver "radeonhd"
Option "monitor-VGA_1" "Daytek LCD TV"
Option "monitor-DVI-I_2/analog" "Daytek 17 inch CRT"
Option "RROutputOrder" "Daytek LCD TV"
Option "DRI"
EndSection

The Option "HPD" "off" is no longer required.

My server layout section seems to be ignored.
