Monitor wont turn on after sleep.

Hi there,
Not sure if it suppose to be here, or in "Kernel and Hardware".
I have a Dell Latitue E5410 with Intel HD Graphics and Arch Linux Kernel 3.2.2-1-ARCH and the system is up to date (no testing repos enabled).

Recentyl I noticed that the laptops monitor wont turn on after sleep. The laptop enters to sleep either after closing the lid or manually after one hour of inactivity. When I wake it up, it wakes up (the activity leds of HD, wifi and bluetooth are working) but the screen wont. Today I had an external monitor attached via VGA (two monitor layout) and the laptop went to sleep mode. After waking it up the external monitor was active but not the laptops monitor. I tried to change the layout via ARandR but nothing helped and only complete shutdown and turn on did.
I suspect the xorg update that happend recently, but not sure.

Any help would be appriciated. Thank you!

[EDIT]
I downgraded xorg-server and xorg-server-common to 1.11.2-2 (from the current 1.11.3-1) and it did not help. I must also add that during the wake up the monitor is inactive at all because I cannot switch to different terminal (for example Ctrl+Alt+F1) so Im not sure its the xorg issue, maybe more a kernel/module issue.

I have the exact some behavior and I'd like to find an answer too (->up). Be kind to share if you solve it, I'll do the same !

Other thing, could you please share your xorg.conf ? I can't use the external vga

Thanks in advance

Nevermind the external monitor prob, i915.modeset=1 was forgotten and did the trick...
Still have the same "resuming from sleep" bug

Thank you in advance.
