F9 - DPMS not working

[John Horne]

Hello,

Using F9, with KDE 4.0.4 desktop, my LCD display never seems to enter
power-saving mode. I have a screensaver configured to kick in after 5
mins, and that works fine. The Xorg log file shows that DPMS is enabled,
as does 'xset -q'. Running 'xset dpms force off' (or standy/suspend) and
the screen turns off, so it can do it. I have left the system for nearly
an hour, but the monitor is still on. This occurred under the vesa
driver, but I have today installed the latest Nvidia drivers and the
problem still exists. F8, using the same hardware, had no such problem.

Any ideas, suggestions?


Thanks,

John.

I think the problems with DPMS are probably general to all drivers. I 
did a fresh installed of fedora 9 on the box I am using now. This has an 
old Matrox 400 card, and has seen many versions of Linux. For the first 
time in years, the install did not pick up the screen type automatically.

I also see a problem with F9's DPMS being unreliable under gnome and
the Radeon Xorg driver.  I don't use one of the chew-up-your-cpu
screen savers (I just have a blank screen).  Sometimes when I come
back after *hours* the screen is still on and displaying my desktop.
I've learned to just hit the manual screen saver button on the lower
right-hand side of my Samsung LCD.

Same occurs using the vesa driver - automatically start screensaver and
it is always there; start it manually or just let dpms kick in and the
screen blanks.

Not necessarily.  I'd still feel better if you could reproduce using
fedora-provided drivers.

Fwiw, I can't reproduce this (so far).

Upon further investigation, the problem *only* occurs if the "Start
automatically" option is set when configuring a screensaver. Disable the
option, and DPMS works as expected. Most odd. Bugzilla'd at
https://bugzilla.redhat.com/show_bug.cgi?id=449280

This is not a graphics card driver problem.

Nope.  But you can remove the nvidia stuff (I think by running
nvidia-installer, if you didn't install the Livna packages) and set up
the vesa driver again.

Not sure that will help. Now that I have installed the nvidia stuff, if
I run vesa again it reports as coming from nvidia, not from the Fedora
supplied one. I suspect the Fedora people will not accept that.

Generate some traffic here:

        https://bugzilla.redhat.com/show_bug.cgi?id=351661

and let's see if we can't get some action on the vesa driver.  If you
can, update the version to 9, otherwise, include the fact that it is F9
in your comment.

Team Fedora won't help with the nVidia driver issue.  For that, check
out the nVidia fora.
