Bug Description

Current Operating System: Linux Dual1.25G 2.6.15-10-powerpc-smp X Window System
Version 6.99.99.904 (7.0.0 RC 4) ATI 9000Pro dual head.

FBMerged will not create two displays of the same resolution in non-clone--seems
to default to cloned every time. If I request a resolution that one monitor can
not support, I have a Xserver start with one monitor (the other one shows
monitor out of range)--I then can use XRandR to change to a resolution that
allows both monitors to work. If I change the default to my "normal" resolution,
the next login will cause a .xsessions error. Xorg.0.log shows no errors.

Same problem here. Dual head works properly in Breezy with my manually configured xorg.conf. In Dapper I get the same effect you described.

I use the following config and it seems to work - I am able to switch between clone and "dualhead" modes using xrandr (even if xrandr shows negative refresh rates).

What is different in your configurations?

resapplet 0.0.7+cvs2005
xserver-xorg-driver-ati 6.5.7.3-0ubuntu5

A working config was reported for dapper, so basically the configuration for similar multihead setup just changed, I guess.
I've working similar setup in 6.06 and 6.10 with MetaModes stuff.
