Bug#557578: xrandr: no index printed
On the man page we see
-s, --size size-index or --size widthxheight
This sets the screen size, either matching by size or using the index into the
list of available sizes.
However, there is no more index printed out when one just does "xrandr",
so one has to count by hand, and remember the first item is 0 not 1.
Also it seems this simple 'try some other resolutions' task is a good
candidate for an example, however it took me a long time to figure out
from the man page that all I wanted to do was xrandr --size 1 etc.
Also wow, all this version conflict info all over the man page...
