Can't disable screen dimming

kaipee · 2012-10-28 11:36:54

I'm using Gnome Shell and can't seem to find a way to completely disable screen dimming on my desktop. It seems to disable roughly after 1 hour, which is really annoying when watching movies in XBMC.
I have set DPMS to off but this doesn't seem to have any effect.

flipper T · 2012-10-28 11:53:28

i use a combo of commands to ensure no dimming:

xset s off
xset s noblank
xset -dpms

...works for me

Please post the output of 'xset -q'.

Next to last line says 'DPMS is Enabled'. Turn it off and see if it helps.
flipper T provided nice options (xset -dpms), read the wiki if you need more info: https://wiki.archlinux.org/index.php/Di … _Signaling

kaipee · 2012-10-28 13:38:07

Thanks karol , though I know I set it to disabled before, wierd lol

I'll not change this to SOLVED until I get a chance to test it with XBMC later

flipper T · 2012-10-28 16:00:20

"xset -dpms" is not persistant & does not survive a reboot.

"weirdness" solved.

aah that would be why lol
How do I set it to be persistent? Or how do I persistently disable dimming?

karol · 2012-10-28 16:08:07

You can put it e.g. in ~/.xinitrc.

kaipee · 2012-10-28 16:09:17

I'm native systemd, am I right in that ~/.xinitrc isn't used with systemd?

flipper T · 2012-10-28 16:14:48

create a text document called .xprofile in you home directory.

in it put the command, save, reboot, smile.

ps i have the 3 commands previously posted in mine.

kaipee · 2012-10-28 16:18:16

So I have ~/.xprofile and it will look like:

xset s off
xset s noblank
xset -dpms

correct? do I need the #!/bin/sh ?

flipper T · 2012-10-28 16:19:52

no. that's fine.

you are good to go.

Great, thanks flipper T.
I'll reboot and leave until later before I mark solved

kaipee · 2012-10-28 20:02:26

OK so I rebooted, went shopping, came back and the screen was black (kind of like when locked, but wasn't locked)

flipper T · 2012-10-28 21:09:17

not your day, is it ?

take another look at xset -q.

if changes to screensaver & dpms have been made, i'm out of ideas.

kaipee · 2012-10-28 23:08:46

It never seems to be my day with Arch lol. Have a look at my other issues

For some reason, standby and suspend seem to have reverted to 600 (though DPMS does seem to have kept itself disabled)

flipper T · 2012-10-28 23:19:57

i think that the standby / suspend values are not relevant if dpms is disabled.

what desktop environment are you using?

could it be a DE specific setting / screensaver?

(you have probably guessed that i'm no expert, just suggest stuff that worked for me)

kaipee · 2012-10-28 23:22:28

Using Gnome Shell
Brightness and Lock (settings) is configured to turn off screen when inactive for 1 hour - though there is no option to disable it.

Also have noticed that gconf settings I change manually don't keep after a reboot

kaipee · 2012-10-28 23:29:04

Well, looky what I found
Gnome Shell plugin

I'll test and see how it works

kaipee · 2012-11-10 19:17:40

OK so this plugin doesn't work with Gnome 3.6 (which I now stupidly have on my laptop)

So I need to come back to finding a solution to preventing the display from sleeping. (also noticed I cannot stop the suspend mode when closing laptop lid - nothing works)

r10t · 2015-03-28 16:53:45

might be some monitor mode, my LG always dims when set to movie mode.
