DPMS Turns Itself On

[IanSammel]

I investigated the problem a bit more. As I mentioned above, DPMS gets turned on when I enter the administrator password when doing a software update. If I turn it off whilst the download is still in progress then it gets turned on again when the actual update starts. Still no idea what's causing it though.

Any news about this issue? It is getting really annoying to have to move my mouse every 9 minutes so the screen doesn't go blank while I watch a movie

Add the following lines to ~/.bash_profile (If .bash_profile does not exist create it -- notice it is a "hidden file", its name begins with a period.)

xset dpms 0 0 0
xset -dpms
xset s noblank

Zeros are supposed to turn off those settings, but you could use

xset dpms 32547 48820 65094

to make the times longer than a movie.

dpms flags...
The dpms option allows the DPMS (Energy Star) parameters to be set. The option can take up to three numerical values, or the `force' flag followed by a DPMS state. The `force' flags forces the server to immediately switch to the DPMS state specified. The DPMS state can be one of `standby', `suspend', `off', or `on'. When numerical values are given, they set the inactivity period (in units of seconds) before the three modes are activated. The first value given is for the `standby' mode, the second is for the `suspend' mode, and the third is for the `off' mode. Setting these values implicitly enables the DPMS features. A value of zero disables a particular mode.

this seems to work for me for the moment, thank you

I have the same problem and look forward to a possible resolution!

[slopechz50]

Can someone explain how to do this? I don't think I did it correctly.

xset dpms 0 0 0

stopped the blanking. I put that command into ~/.bash_profile

Dragon Player is causing DPMS to turn on on my system. Its happened a couple times where I turn DPMS off, watch a video and as soon as I close Dragon Player, the screen blanks.

It also seems that messing with DPMS breaks power management. Power management on my system is as useful as a coprolite.

#!/bin/sh

# no sleep display

xset -dpms;

xset s off

setterm -blank 0 -powerdown 0


exit 0

copy this into your favorite text editor and save it to /home/your user name/.kde/Autostart
make it executable
reboot

Thanks! Is there anything else I need to do? I tried the script out, but it seems to be sleeping even more now.

On the other hand, I can go to System Settings > Power Management > Energy Saving Settings and check the box next to Screen Energy Saving, and then set the time as high as it will go (360 min). Since I don't think I'll ever be watching anything for 6 hours straight, this seems like a reasonable workaround.

Just tried this. I thought this issue was resolved, but Ubuntu did update the kernel yesterday. I have no idea if that is the issue that has started this problem again. Thank you.

#!/bin/sh
#
# no sleep display

xset -dpms;

xset s off

setterm -blank 0 -powerdown 0


exit 0
-----------------------------
copy this into your favorite text editor and save it to /home/your user name/.kde/Autostart

This has worked for a while, but after recent updates, it's gotten a lot worse. DPMS is now turning itself on and resetting itself to default values extremely frequently, and I don't know what the cause is.

[GreyGeek]

I go the other route, set the blanking to far into the future ... 32000 seconds...

xset dpms 32000 32000 32000
xset s noblank
xset -dpms

DPMS seems to be resetting itself when I view videos in Firefox. Both Flash and HTML5. But it doesn't seem like it's every time.

Does this nonsense happen in GNOME or Unity, or any other KDE-based distro? I'm really getting tired of dealing with this.

EDIT: I think it might actually be VLC that's resetting DPMS.

Hooray for Vlc! XD
Try out Smplayer+Mplayer2 combo, works much better for me than Vlc.

I'm also using this combination now. I tried many GUI front-ends for MPlayer; SMPlayer is the only one I could find that passes the left-bracket and right-bracket keys to MPlayer to speed up or slow down playback.
