Re: dpms problems with X 4?



I've had DPMS problems with  4.0.2 as well, though different from what
you  describe.  In my  case,  APM seemed  to  conflict  with DPMS.  In
particular, the sequence

xset dpms force suspend
apm --suspend

did not work as expected (the second line would cancel out the effects
of the first).  FWIW, I've now turned on the  "DPMS on suspend" option
in  BIOS,  and  commented  out   the  call  to  xset.  This  works  as
advertised.
