Hi,

I have a Gigabyte GV-R455D3-512I which is essentially a Radeon HD 4550
graphics card. It's not quite operating properly, particularly when
connected to two monitors.

However, I have a probably-not-very-common setup and this might be
causing the issue somehow, and it may not necessarily be a bug in the
radeonhd driver. So, I'm not sure, and hopefully you can point me in
the right direction to investigate further.

Hardware setup:

Dell 640m laptop with an Intel 945GM integrated graphics card
ATI Radeon HD4550 connected via an Expresscard-to-PCIe 1x adapter

The hardware seems to be working properly, and the radeonhd driver
mostly works with a single monitor.

Software setup:

Ubuntu Hardy Heron
  - linux 2.6.24 ish
  - xserver-xorg 1:7.3+10ubuntu10.2
    - xserver-xorg-core 2:1.4.1~git20080131-ubuntu9.2

with xserver-xorg-video-ati 1:6.12.1-0ubuntu1~hardy from
https://launchpad.net/~tormodvolden/+archive/ppa

XOrg.0.log also says:

(II) RADEONHD(1): Unknown card detected: 0x9540:0x1458:0x21AE.
  If - and only if - your card does not work or does not work optimally
  please contact radeonhd@xxxxxxxxxxxx to help rectify this.
  Use the subject: 0x9540:0x1458:0x21AE: <name of board>
  and *please* describe the problems you are seeing
  in your message.

so you probably should at least update your hardware ID numbers.

When I have a single monitor attached to the Radeon, I can change the
screen resolution with command line xrandr.

When I have two monitors attached to the HD 4550, and I log into
Gnome/X, my mouse cursor stays within Screen 0 (the Intel graphics)
and I can't move over to focus onto Screen 1 (the Radeon).

If I have one monitor attached, and I log into Gnome/X, I can move my
mouse between Screen 0 and Screen 1 (so I can do stuff on Screen 1)
However, if I then attach the second monitor to the Radeon, I cannot
set the second monitor to a non-Off resolution from command line
xrandr.

(Throughout this, there is no external monitor attached to the Intel
945GM, only the laptop's internal LVDS).

Is it possible I need an up-to-date xserver-org-core? Or perhaps the
HD 4550 isn't well supported by radeonhd at the moment?

I can also provide logs and re-do my testing if required, but I didn't
want to jump the gun yet.

Thanks for any help you can provide.
