Public bug reported:
In the "energy saving" applet on kubuntu 15.04 I have the "dim screen"
checkbox marked (5 minutes)
If I leave the computer untouched for this period of time, the screen
correctly dims.
However it does not restore to nornal brightness when the computer is
used - ie keyboard touched. This is big usability issue as it means
after idle I have to manually return the brightness level to something
usuable, unlike windows for example where a simple touch or mouse move
will revert the display to the correct brightness level.
My workaround for this is to disable the auto-dim, and just reduce the
screen timeout a little as after blanking the brightness does go back to
normal, but this isn't ideal
computer is a Lenovo Thinkpad W530. I'm using the proprietary nvidia
drivers provided with ubuntu (3rd party option). Currently I am only
using external display though am configured for int+dvi+displayport
which I use in the office. the issue still occurs there on internal
display only.
