[Solved] xset dpms force off not working

With the latest kernel 'xset dpms force off' is not working, now it makes my screen blink (off/on in one sec).

With 'sleep 2 && xset dpms force off' and 'sleep 2; xset dpms force off' I got the same result.

vbetool works.

Re: [Solved] xset dpms force off not working

I finally found a way to fix it. With the lastest kernel versions the module topstar_laptop sends a event that
get in the way:

kernel: [43419.820250] topstar_laptop: unknown event = 0x82

Module added to blacklist and until now everything working as should be.
