Public bug reported:

Binary package hint: xorg

I have a laptop (Sony Vaio VGN-SR51MF/S) which I use together with an external monitor (Benq G2410HD). I'm running Kubuntu Lucid (development version, latest updates installed).
The video card is an Ati Monility Radeon 4530 HD; i'm using the xserver-xorg-video-ati drivers.

When looking at Screen settings, there is printed (Auto) after the
correct native resolutions for both the laptop screen as the external
monitor.

What the system does when booting while the HDMI cable is already
connected and the external monitor is switched on, is that it enables
the external monitor in clone mode (which is good), but it sets both
displays to 1024x768. This resolution is lower than both the native
resolution of my laptop (1280x800) and the native resolution of my
external monitor (which is 1920x1080).

What I would expect that if the system can detect which resolution is
the native resolution, it would enable clone mode and set the
resolutions to the respective *native resolutions* instead of setting
them both to 1024x768.
