Intel HD 4000 (onboard video) does not wake up monitor

Just built a new system based on an Intel i7 that has integrated video.  I am using extra/xf86-video-intel.  When my monitor goes to sleep however, moving the mouse or typing on the keyboard does not wake it up anymore.  I have to CTRL+ALT+F1 which does wake it up.  Then I have to CTRL+ALT+F7 to get back to X.  Is this a known issue?

This seems to be a function of the sna acceleration.  Switching to uxa seems to have solved it.  I'd like to keep using sna as it is noticeably quicker.  Suggestions are welcomed.

Re: Intel HD 4000 (onboard video) does not wake up monitor

I'm running Intel HD 4000 with sna acceleration but I can wake up my monitor just fine. Granted, this is a laptop and not a desktop, but I'm not sure how that would make a difference.

Anyway, I can't think of anything in particular that might be causing the problem but if you want to compare notes, feel free to ask for info on my setup.

This is fixed in xf86-video-intel 2.20.3-1 currently in[testing].  Good job devs!

$ cat /etc/X11/xorg.conf.d/20-intel.conf

Re: Intel HD 4000 (onboard video) does not wake up monitor

I recentlly built a similar system (i7 with integrated Intel HD 4000), and I'm seeing the same behaviour that graysky reported. When my monitor goes to sleep, moving the mouse or typing on the keyboard does not wake it up. I have to CTRL+ALT+F1 which does wake it up. Then I have to CTRL+ALT+F7 to get back to X. This happens with SNA acceleration, but not with UXA. I'm running xf86-video-intel 2.20.5-1, which are the latest in [extra].

Is anyone else seeing this behaviour?

Just unmarked as solved... Works fine for my user, but does this behavior when the wife logs in... Odd and definetly unsolved.

having the same issue here.  I've disabled screenblanking and energy saving settings as a patch to keep it from turning off in the meantime.

It is obviously a highly sensitive piece of equipment.

I assume you have compared your groups to hers.

Re: Intel HD 4000 (onboard video) does not wake up monitor

I got the same error message that was in the link:  [drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting
They seem to be aware of the issue at least.  Coincidentally my external monitors are both dell, and connecting through displayport.

A safe assumption.  Identical except mine is in the wheel group.

Re: Intel HD 4000 (onboard video) does not wake up monitor

What I did was set grub to boot with GRUB_CMDLINE_LINUX_DEFAULT

acpi_backlight=vendor

and then I added this script to /etc/pm/sleep.d/restore_brightness

#!/bin/bash
case "$1" in
   suspend|hibernate)
      #do nothing
   ;;
   resume|thaw)
      echo 7 > /sys/class/backlight/toshiba/brightness
   ;;
   *)
      exit 1
   ;;
esac
exit 0

This is of course predicated on the condition you are using intel 4000 hd with a Toshiba laptop.

Are there any news regarding that wakeup issue with SNA? I have a similar problem using an Intel 5700MHD chip.

Re: Intel HD 4000 (onboard video) does not wake up monitor

Today I tried linux 3.6.11 and xf86-video-intel 2.20.16. No more problems with these.
