This isn't a driver bug. It's the default behavior of the xserver. By default, unless you specify otherwise, the xserver attempts to set all connected monitors to the same mode (whatever mode is common between all monitors if possible). If you want different behavior you need to specify preferred modes in your xorg.conf. See this page for more information: http://wiki.debian.org/XStrikeForce/HowToRandR12 Thank you for this information. Setting the option "PreferredMode" seems to work but just for my understanding: I'm still wondering why by default 1152x864 is choosen, as a) the highest common resolution of both displays is 1280x1024 b) the laptop is on a docking station and the lid is closed. The external monitor is the only one so I would expect Xorg to set it to its native resolution without having to set it in xorg.conf (I didn't have an xorg.conf at all before) Please attach your xorg log.

At the moment they are handled by acpi so you'd have to set up an event handler to deal with them and do the appropriate thing via xrandr. Created attachment 29299 [details]

The lid is closed all the time since bootup, so there is no lid event. Doesn't the radeon driver notice that the internal display is turned off/closed? |
