SUMMARY:
xset blanking delays occur in series not parallel
xset dpms 30 60 90 means a total of 180 sec before monitor off
thus xset dpms 90 60 30 should also be legal -- but it is not



Hi!

$ xset dpms <seconds> <seconds> <seconds>

sets the delay before X turns your monitor to standby mode, to
suspend mode, and then off.

Pretty simple.  Seems to work fine too.  Sample output:

$ xset dpms 30 60 90
$ while true; do echo "`date +%T` `xset -q | grep Monitor`";
sleep 10; done
00:59:01   Monitor is On
00:59:11   Monitor is On
00:59:21   Monitor is On
00:59:31   Monitor is in Standby
00:59:41   Monitor is in Standby
00:59:51   Monitor is in Standby
01:00:01   Monitor is in Standby
01:00:11   Monitor is in Standby
01:00:21   Monitor is in Standby
01:00:31   Monitor is in Suspend
01:00:41   Monitor is in Suspend
01:00:51   Monitor is in Suspend
01:01:01   Monitor is in Suspend
01:01:11   Monitor is in Suspend
01:01:21   Monitor is in Suspend
01:01:31   Monitor is in Suspend
01:01:41   Monitor is in Suspend
01:01:51   Monitor is in Suspend
01:02:01   Monitor is Off
01:02:11   Monitor is Off
01:02:21   Monitor is Off
01:02:31   Monitor is On
^C
$

Note that it took exactly 30 seconds to reach standby, 60 seconds
AFTER THAT to reach suspend, and then ANOTHER ADDITIONAL 90
seconds
before the monitor turned off.  Great, I get it, now I know how
to ask for what I really want.

So!  Suppose we want X to wait three minutes before standby and
then 30 seconds each before suspend and off?

$ xset dpms 180 30 30
illegal combination of values
  standby time of 180 is greater than suspend time of 30

Oh no!

OK, this is not of earth-shattering importance, but on the other
hand it should be really easy to fix.

Thanks!
