xrandr complains that it cannot find the mode:
$ xrandr --output VGA-1 --mode 1280x720
xrandr: cannot find mode 1280x720
it only shows one possible mode (but in the older Ubuntu version I could chose multiple ones):
$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2047 x 2047
VGA-1 disconnected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 (0x13a) 75.0MHz
h: width 1024 start 1048 end 1184 total 1328 skew 0 clock 56.5KHz
v: height 768 start 771 end 777 total 806 clock 70.1Hz

and adding the mode fails:
$ xrandr --newmode "1280x720" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync -vsync

I wonder what kind of applet you mean as the standard Ubuntu desktop settings do not allow mto change any resolution.

My fault, sorry. the randr call should have read :
xrandr --output VGA-1 --mode 1280x720
Use plain 'xrandr' to get a list of all supported modes.
'man xrandr' for more details.
Also, it might be easier to use some desktop applet rather than the
command line to use RandR.

Xavier
