Public bug reported:
See the four separate issues (all of which affected me and some of which
affected others) documented at https://bugs.kde.org/show_bug.cgi?id=128696,
https://bugs.kde.org/show_bug.cgi?id=129717,
https://bugs.kde.org/show_bug.cgi?id=129999, and
https://bugs.kde.org/show_bug.cgi?id=130001.
In short, DPMS values do not stick, if you go into administration mode,
your xorg.conf file is liable to being completely screwed up (which
causes a crash for those using one of the display managers rather than
the startx method), even if you avoid administration mode, your screen
resolution gets screwed up, and only one DPMS time delay, OffTime, is
controlled by the displayconfig module when it should be all three of
them (StandbyTime, SuspendTime, and OffTime).
Until these many issues with displayconfig are resolved I suggest to
users that they disable displayconfig (put NoDisplay=true as the last
line in /usr/share/applications/kde/displayconfig.desktop) and install
kcontrol and use the tried and true display module instead (which must
be enabled by commenting out the NoDisplay=true line at the end of
/usr/share/applications/kde/display.desktop).
To make this last change official until the many upstream bugs in
displayconfig are fixed, I suggest to the kde-guidance team that they
take whatever technical measures are necessary to simply replace the
displayconfig module with the display module in the kde-guidance
package.
