Red Hat Bugzilla – Bug 19842
Monitor not being put to "stand-by"
Last modified: 2008-05-01 11:37:59 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..)
No, xset dpms force standby does not do it. If I do an xset q then I get:
prefer blanking: yes
allow exposures: yes
DPMS (Energy Star)
DPMS is enabled
Monitor is on
This is from enabling power saving in the screensaver section of the gnome
I have this problem too. I have an NVidia TNT2 and a sceptre dragoneyes D98A
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
I fixed this by putting the line:
in the /etc/X11/XF86Config-4 file in the Monitor section. I have heard that if
that doesn't work, try putting
The guys on the X newbie list rule!
Hope that works for you!
The Option "DPMS" line in the /etc/X11/XF86Config-4 file in the Monitor section
worked a treat for me.
This really needs to be done by Xconfigurator; it's not an xscreensaver bug.
It's been added in CVS a couple of weeks ago...
also, the monitor you speak of is now listed, among many others.
