Description Peter D. 2010-08-16 22:41:08 UTC 
Two different modes can not both be the default mode, but the output of xrandr indicates that this is so.  (Two modes are marked with a "+".)  

I am using xrandr 1.3.2 and the open source ati driver on an X550 video card.

Comment 1 Aaron Plattner 2013-02-06 18:06:20 UTC 
'+' means "preferred" mode, not default mode.  In this case, xrandr just puts a + next to any mode in the preferred mode list.  The RandR 1.2 protocol explicitly lets the server return multiple preferred modes.

If there's an xrandr bug here, it's that the man page says modes are listed, "with a '+' after the preferred mode" rather than "with a '+' after the preferred modes."
Comment 2 Aaron Plattner 2013-02-12 22:53:07 UTC 
Should be fixed in xrandr 1.4.0.
