This recipe installs a init script to disable console blank
Hi Jason,
I had a bit of a look at this DPMS issue, I might have a solution it
is somewhat hacky but appears to allow for DPMS to function correctly.
https://github.com/nathanrossi/linux/commit/e4264e80116684297e353f6da4156c4ad6f8a03a
It would be nice to avoid this console blank + xorg config setup and
have DPMS work (albeit with a kernel patch). Would you be able to
confirm if the above linked patch fixes the DPMS issue with your setup
too?
It works for me but just to let you know that the patch does not fix the
DPMS issue, as you can still see the same issue if you force the
framebuffer into the sleep mode.
sorry i mean it works if i don't try to force the fb into sleep mode.
Patch does prevent the console blank, the problem was the doggy hdmi->
dvi cable.
Cheers,
Jason
