https://bugs.freedesktop.org/show_bug.cgi?id=82527 --- Comment #13 from Martin Väth --- By accident, I am now traveling and have access on the machine for 1 or 2 days. I installed linux-3.17.2, and have still exactly the same faulty behaviour as described in the original posting: xset dpms force off holds for about 20 seconds and then switches on again. -- You are receiving this mail because: You are the assignee for the bug.
