Position all the bar from the gnome manager prefrence on "Never" 2. Reboot the computer 3. Wait until the DPMS was activated or check it with the command "xset q" Actual results: The DPMS is enabled.

My attachment is the result from an experiment. I have tested three configuration, and I have rebooted my laptop between each test. Maybe it's not necessary. The third configuration test is problematic. We should not have : DPMS (Energy Star): Standby: 1200 Suspend: 1800 Off: 2400 DPMS is Enabled Monitor is On But : DPMS (Energy Star): Standby: 0 Suspend: 0 Off: 0 DPMS is Enabled Monitor is On Thanks for all, Sébastien Bertrand.

Can you attach your /etc/X11/xorg.conf file please. Thanks.

Young-Ho, that patch looks good, thanks. I've committed it to 2-18 and trunk. Sébastien, could you try with the patch, and see if it fixes the issue for you? Thanks to you both.
Ok. I assume this patch has been committed inside Ubuntu Feisty Fawn (GNOME 2.18). I follow the procedure to reproduce the bug and "xset q" give : DPMS (Energy Star): Standby: 0 Suspend: 0 Off: 0 DPMS is Enabled Monitor is On Which is correct. There is still no DPMS inside my xorg.conf file. So, from my point of view, this bug is resolved. Thanks.
seems to be a "feature" of xorg https://bugs.freedesktop.org/show_bug.cgi?id=9497
