Public bug reported:
I've a Kubuntu Toshiba A110 with a 1280x800 display. I did like to set
poweroff time of my display at 5 minutes. After applying, it functioned
properly.
Two problems were caused by this bug:
1. Next morning the X system didn't start. /etc/X11/xorg.conf was changed in
such a way that my settings were incorrect. I assume that the settings were not
completly accurately copied and consequently wrongly written back. I only
wanted to change the poweroff time...
I replaced xorg.conf and started again.
2. Now the poweroff time was 5 hours instead of 5 minutes. I traced the
file displayconfigrc (in .kde/share/config) with the following contents:
[General]
targetgamma=2.0
[Screen0]
dpmsEnabled=on
dpmsSeconds=300
height=800
reflectX=0
reflectY=0
refresh=60
rotate=0
width=1280
Obviously the dpmsSeconds are treated as minutes. I changed the
dpmsSeconds to a value of 5 and indeed the display powered off after 5
minutes. Only exception is after starting a session, than it takes about
5 seconds to power of the display.
So I assume that on several places minutes and seconds are mixed up.
Further I think that only setting poweroff behaviour should not change
the xorg.conf file.
I'm installing two laptops, both had same problem.
Thanks for solving this.
