DPMS will keep switching monitor on and off

Fri Sep 2 03:29:28 PDT 2011

Some time ago there was a patch [1] merged in which was designed to fix 
DPMS (monitor would go on/off all the time [2] instead of just going 
off), I was happy to see this one but unfortunately it doesn't work for 
me - I still experience the same behaviour.
I'm terrible lazy so I didn't report it before but seeing that some 
"unrelated" change might be the cause of bug in dri code (as in #42162) 
got me wondering.

Should I open a bug report for it ?
