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