I'm not completely sure what's going on here. fglrx properly supports xrandr and uses the Xorg XINERAMA extension to describe monitor placement for the window manager. So this is likely due to some quirk of the hybrid graphics, or maybe something with your xorg.conf file. I'd be interested in knowing if this xorg.conf file works correctly for you:

Code:

Section "Monitor"
        Identifier   "LVDS1"
        Option "PreferredMode" "1366x768"
EndSection

Section "Monitor"
        Identifier   "VGA1"
        Option "PreferredMode" "1600x900"
        Option "RightOf" "LVDS1"
EndSection

Section "Device"
  Identifier "Default Device"
  Driver "fglrx"
EndSection

Section "Screen"
  Identifier "Default Screen"
  Device "Default Device"
  Monitor "Default Monitor"
  DefaultDepth 24
  SubSection "Display"
        Depth 24
        Virtual 2966 2966
  EndSubSection
EndSection

This is basically my xorg.conf file, but with the Identifiers for the monitors changed.

Same thing with your xorg.conf, 1 big freaking desktop with windows stretching everywhere, this is so frustrating. Thanks for you help so far Adam.

Unfortunately, then, I'm not sure what's going on. I know that the fglrx drivers keep some configuration in /etc/ati/amdpcsdb but I don't know of anything in there that would cause your XINERAMA extension to display the wrong information.

Ideas anyone? Upgraded to 4.8.0 no change.

you could try to run

Code:

aticonfig --initial=dual-head --screen-layout=right

which should result in :0.0 on the first screen and :0.1 on the second one. you should be able to move the mouse between the monitors, but -- at least in fluxbox -- both desktops will act seperately.

You might try

Code:

aticonfig --initial=dual-head --dtop=horizontal --screen-layout=right

mysql_connect,

amdcccle does have display config in it.

Start it up, click on 'Display Manager' under the 'Pages' section, and both your monitors should be listed.

If you then switch to the 'Multi-Diplay' tab, it should allow you to configure your multiple monitor setup, the default seems to be cloned displays, this might be your problem. Change the selection in the drop down list to switch away from cloned.
It does require a reboot (or restart of X) to enact though.

This is the way I've always done it, never needed to mess with the X configs, hope it helps...

As I state in my previous posts I have tried everything (and posted my xorg conf, X log, etc), amdcccle doesn't show any display options as you can see here:

mysql_connect: Sorry, I obviously misread your first post.

The only other thing I can think is that you are running amdcccle without root privileges, or that you haven't run aticonfig yet (which has already been suggested). I assume there is nothing helpful on the 'Switchable Graphics' screen.

Either way, it doesn't seem like its to do with that utility anyway, more to do with X, and I don't have much experience in that area.

Sorry I couldn't be more help, hope you find a solution soon.
