OK, I've been fighting with ATI/fglrx/compiz for a while now, and I can usually get it mostly working.
I started a new job and decided to stick Kubuntu on the machine provided. (It was a pre-installed dual-screen vista machine). The machine has an ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]
Now, I had it running fine on a single screen using 8.42 and Xgl, although I did have a second screen (that remained Decorator-less) that I used for specific applications (fullscreen firefox for example). It wasn't quite how I wanted it, but it was functional, and both screens were 1280x1024.
I installed 7.11 drivers and with a bit of messing around managed to get it running using AIGLX, Compositing and no Xgl (yay). And even better, it's now running just fine on dual-head. BUT, the resolution of each screen is now 1024x768. Xorg.0.log doesn't even show 1280x1024 as an option for either screen, let alone 2560x1024 as an option for bigdesktop.
Does the 7.11 not have the full range of resolutions available?
Any pointers in the right directiong greatly appreciated. Let me know if you need any logs/configs etc...
OK, further research indicates it's a bug with fglrx not reading EDID information correctly when in a dualhead configuration: http://ati.cchtml.com/show_bug.cgi?id=160
Anyone know of a workaround, or anything, or should I twiddle my thumbs until it's looked at...
