Description Simon Oldfield 2000-10-25 23:29:10 EDT
I have an Hitachi CM753 monitor on a machine running RedHat 7.0.  The 
CM753 monitor is not in the standard list (though I thought it was 
supposed to be : refer bug #14951), however it detected its frequency 
ranges correctly.  Unfortunately, despite enabling power-saving mode in 
the gnome screensaver configuration tool, the monitor is never put into 
standby mode.  It used to be when I was running RedHat 6.2 with a modified 
CM751 (I think) monitor entry.

Does 'xset dpms force standby' do it? (I would guess so, but..)
Comment 2 Simon Oldfield 2000-10-30 15:27:24 EST
No, xset dpms force standby does not do it.  If I do an xset q then I get:

Screen Saver:
  prefer blanking: yes
  allow exposures: yes
  timeout: 0
  cycle: 0

DPMS (Energy Star)
  standby: 0
  suspend: 0
  off: 1200
  DPMS is enabled
  Monitor is on

This is from enabling power saving in the screensaver section of the gnome 
configuration tool.

I have this problem too.  I have an NVidia TNT2 and a sceptre dragoneyes D98A
monitor.
xset +dpms
xset dpms force (off|standby|suspend)
all fail to do anything.

It worked with RH 6.2  Perhaps this is an X 4.0 bug?

this looks to be the same bug as bug #20804
Comment 4 Need Real Name 2000-11-17 15:56:20 EST
I fixed this by putting the line:
	Option "DPMS"
in the /etc/X11/XF86Config-4 file in the Monitor section.  I have heard that if
that doesn't work, try putting
	Option "power_save"

The guys on the X newbie list rule!

Hope that works for you!
Comment 5 Simon Oldfield 2000-11-17 17:49:03 EST
The Option "DPMS" line in the /etc/X11/XF86Config-4 file in the Monitor section 
worked a treat for me.
Comment 6 Bill Nottingham 2000-11-19 00:57:54 EST
This really needs to be done by Xconfigurator; it's not an xscreensaver bug.
Comment 7 Trond Eivind Glomsrxd 2000-12-06 14:58:33 EST
It's been added in CVS a couple of weeks ago...
Comment 8 Preston Brown 2001-01-29 14:06:39 EST
also, the monitor you speak of is now listed, among many others.
