if i leave the laptop idle for a longer period of time (about 30min) when i come back i have no power to the display. the system is running and i can change music from the keys or shutdown, but nothing wakes-up the monitor. didn't noticed this on 3.6.11, also i have this xorg.conf for years now.
:: Code ::
Section "ServerFlags"
   Option "DontZap" "Off"
   Option "AllowMouseOpenFail" "true"
   Option "BlankTime" "3"
   Option "OffTime" "5"
EndSection

from what i have seen if it idles for 3 min and goes to blank screen if i move the mouse it turns on, same for 5+ min. the problem occurs after longer idles i can't specify the exact period of time.

dark-D, try commenting out those

Option "BlankTime" "3"
Option "OffTime" "5"

and restart xorg, I had issues with 3.6 and 3.7 kernels and my old xorg.conf for mouse, in my case mouse just didn't work, when I removed the mouse sections completely everything worked normally. That's because I had had mouse issues in the past with a kernel change, and then the kernel guys must have actually fixed the cause which made my patches to xorg.conf then break the mouse.

I removed all input device mouse sections and the call to them

# InputDevice "Mouse0" "CorePointer"

but in your case I'd try removing those flags first.

EDIT: hahaha, just i was checking the post for spelling and consistency the monitor entered blanktime, the one set at 3 min, and as soon as it did that i moved the mouse and it wouldn't came out of it. it is definitely something wrong in the last stable kernel. if i can't find out what is to blame, i will set them all at 0. (blanktime, standbytime, suspendtime and offtime). such a shame, i like to powersave as much as i can.

dark-D, do you think this bug is related? bugzilla.kernel.org/show_bug.cgi?id=51921

Maybe you can find a way to get the output of dmesg to a file before you do a restart.

hello damentz, looks about right. if my logs help maybe you can add them to that report, as i don't have an account there.
can you give me a command for terminal so i can use dmesg to a folder? because i have all my applications on key bindings and i can type it blindly.
also, here is what i retrieved:
this is the kern.log for the second post:
pastebin.com/3mMkyFWs
this is kern.log at 4:30 the latest error:
pastebin.com/3HiDeB23
this is /var/log/dmesg at 4:32 this is the time that is shown as the creation of the file:
pastebin.com/xf4MzCvw

$ dmesg > ~/dmesg-output.txt


Also, can you try the newest kernel that's out? I had a feature enabled named rcu_boost which is known to conflict with BFS. It may have also caused the bad behavior on your system.

ok i can confirm two things about the error:
-first is that it is occurring on the 3.7.1-2 kernel.
-second is that it gives the error with no relation to the above stated monitor settings for powersave. it manifested while i was browsing or watching youtube.

here is the dmesg saved to a file:

Can you try the suggestion on LKML? It appears that forcing SNA acceleration in X could work around the issue. You might need to do this until someone identifies which patch caused you problems:

lkml.org/lkml/2012/10/29/77

:: Code ::
Section "Device"
        Option     "AccelMethod" "SNA"
        Identifier  "Card0"
        Driver      "intel"
EndSection


Also, this bug is a high visibility item on the LKML. I'll be watching for any fixes. Will be monitoring for any new patches to test on bugs.freedesktop.org/show_bug.cgi?id=56916.

using SNA and no sign of the error, so far.
