Confirmed issue still exists in Feisty. Both workarounds (XLIB_SKIP_ARGB_VISUALS=1 gnome-terminal, and explicitly turning off Compositing) worked. Also, I was able to get Xinerama working with two different nvidia video cards with the 'nv' driver. The nv driver was not able to activate the second monitor on a two-monitor video card, however.
Also checked multi-gnome-term and found it fails as previous reporter reports; I suspect this is just because MGT is derived from the same codebase so is inheriting whatever codepath in gnome-terminal triggers the bug.
