Description Oliver Henshaw 2009-07-23 15:43:57 UTC 
Version:            (using KDE 4.2.4)
OS:                Linux
Installed from:    Fedora RPMs

In System Settings -> Power Management -> Edit Profiles -> Screen I can configure timeouts for "Standby after", "Suspend after", "Power off after". But according to my Xorg.0.log, standby and suspend are not supported by this monitor:

$ grep -i dpms /var/log/Xorg.0.log                  
(II) Loading extension DPMS
(II) RADEON(0): DPMS capabilities: Off; RGB/Color Display
(II) RADEON(0): DPMS enabled
(II) RADEON(0): DPMS capabilities: Off; RGB/Color Display

Powerdevil should only allow me to change the settings that make sense for my monitor.


Affected packages:
kdebase-workspace-4.2.4-5.fc11.i586
Comment 1 Oliver Henshaw 2009-08-26 19:18:52 UTC 
This is unchanged in kdebase-workspace-4.3.0-9.fc11.i586

I assume Xorg is reporting accurately? In any case, the monitor never enters any kind of power-saving mode on idle.
Comment 2 Dario Freddi 2009-12-01 18:40:34 UTC 
Uhm, actually I'm grabbing the capability from XOrg, I'll see if I can improve that
Comment 3 Oliver Henshaw 2010-10-07 23:58:58 UTC 
What's actually happening is that the monitor's EDID reports that it only supports the DPMS Off state. However any of the DPMS states can be forced with xset, so I don't know whether the EDID is wrong or what.
Comment 4 Dario Freddi 2010-11-09 17:16:32 UTC 
Should be fixed in 4.6
