I don't
know if it helps, but I'm using Trinity 3.5.12 on Debian
Squeeze with the NVIDIA proprietary drivers. I don't have multiple
monitors, but randr seems to work fine. I can resize from the tray
icon anyway.
Using nVidia here as well. In fact, my primary development machines use
nVidia cards. :-)
While nVidia does not have XRandr 1.3+ support (and therefore cannot
handle multiple monitors, etc.) this does not break Trinity. The
appropriate configuration options only become available if the underlying
hardware supports them.
If you really want multiple monitors via XRandr with nVidia cards, try the
nouveau drivers. Be aware that they do not support 3D well at all at this
time however.

Oh, and I forgot to mention that if your distribution does not support the
newer versions of XRandr the appropriate course of action to take is to
turn off libkrandr and krandrtray completely. I do not want to get into
legacy support of older, possibly malfunctioning graphics subsystems
unless I am paid to do it! ;-)
