Created attachment 13982 [details] logfile My Benq G2400W goes blue when DPMS kicks in. I drive it with an ASUS P5E-V HDMI (Intel G35), using git HEAD as of january 25 or so. The connection is HDMI in both ends. I have tried playing with the DPMS modes (not using 'off', only using 'off'), but it does not appear to make a difference.

I think it still is.

Do you have chance to try this on VGA?
The monitor goes to sleep after DPMS kicks in, if connected through VGA. The display goes dark, and the power led turns amber. If connected through HDMI, the panel turns blue when DPMS kicks in. Yanking the cable makes no difference, it stays blue.
Tweaked summery
Tested master now. Still no luck with DPMS.
Just tested with current master. My HDMI-connected monitor still does not suspend when DPMS kicks in.
Reassign Hong's bugs back to the default for triage.
I can't reproduce this with your xorg.conf on my ASUS P5E-VM HDMI board, with HDMI->HDMI connection. Do you mean you see this when BlankTime activated after 5 mins? Below line in your log looks weird, since you says only using HDMI: >> (II) intel(0): Output VGA connected Zhenyu, any idea?
When connected VGA-VGA, the monitor LED turns amber and the panel goes dark when DPMS kicks in. (At least it used to, I haven't tested this in the last few months.) When connected HDMI-HDMI, the monitor LED stays green and the panel turns blue, when DPMS kicks in. I.e. no powersaving. I'd like the same behaviour as for VGA, if possible. It is possible that the two if 0'ed codelines in the i830_sdvo_dpms function of i830_sdvo.c is to blame. The one time I tried to enable these two lines, I had to reboot to get output to the panel again. :-)
Also se my previous comment. I currently have DPMS disabled in xorg.conf. For testing, I enable dpms like this: xset +dpms xset dpms 10 20 30 DPMS will now kick in after 10 seconds of inactivity. xset -dpms disables dpms again.
Created attachment 20201 [details] [review] set SDVO monitor DPMS state This patch applys to current git master, and try to use monitor power state command for DPMS. Please help to test if this works for you.
reassign to Ma Ling, who has the identical hardware (monitor and G35) to test with this.
Tested with patch on top of tonights git. Sorry, no cigar. It doesn't work.
Hi I use the same motherboard & BenQ G2400W display, and reprodeced the issue. However if I unplug HDMI cable with power on, the screen is blue, when I switch it to VGA or DVI mode the screen is black. If I use another HDMI display, the dpms work fine. So the conclusion is not from driver . It belongs to HW Display (BenQ G2400W). Thanks Ma Ling
