xrandr doesn't like cvt's suggestion, says BadMatch

[vwr0527]

My screen should be able to support many resolutions, and included are 960x600. My native resolution is 1280x800.
I know it can do those resolutions easily. So I type "cvt 960 600 50" and I get this: "960x600_50.00" 37.00 960 992 1080 1200 600 603 609 621 -hsync +vsync.
I copy that and do this: xrandr --newmode "960x600_50.00" 37.00 960 992 1080 1200 600 603 609 621 -hsync +vsync
then I do this: xrandr --addmode default 960x600_50.00
then when I do this: xrandr --output default --mode 960x600_50.00
I get this:
X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 156 (RANDR)
  Minor opcode of failed request: 7 ()
  Serial number of failed request: 15
  Current serial number in output stream: 16

I also got this error when I used this modeline: cvt 960 600
which gives this: Modeline "960x600_60.00" 45.25 960 992 1088 1216 600 603 609 624 -hsync +vsync
Anything else?
