dpms problem..

[Jaytee]

To prevent getting a black screen and no sound after ten minutes or so at idle, I do in a terminal this:
xset -dmps

Which has the result of turning off the display power management system for the rest of the session. On reboot dpms starts again.
Does any one know of a script I can use to turn off this feature permanently???

[Jaytee]

Bump any help anyone????

Hmmmm.........


Go into the BIO's settings.
Look for power settings.
Look for Sleep Mode, or Screen Saver.
Disable them, or set the Power Saver Mode to: Always On.

Thanks for your response ET.
My bios has nothing remotely like the suggestions you gave.
I am convinced that it is a system bug and could be fixed by going back a couple of updates. Usually bugs in Linux are fixed fairly quickly but this one is taking a while.
I think I will study the release notes for the next version of Mint (Vera) to see if the problem still exists..

Unless this computer your using is an ancient relic.
It should have "Power Management".
And "Wake System from":
USB
Lan
Keyboard
Mouse

I was looking for love in all the wrong places. I have a gigabyte board with award 2014 bios
I thought i was looking for a specific function to disable which I did not find.
Do I need to disable the PME function????

[Ensign Tzap]

Yes,
You should try disabling the "PME Event Wake Up".
Then see if that solves the Sleeping Issue, every ten minutes when no activity is detected.

There is also, "ACPI Suspend Type".
This setting dictates what power saving state your system goes into.
ACPI replaces the older Advanced Power Management (APM) scheme and requires a compatible OS,
such as Windows 98 and up, along with several Linux distributions.

Many thanks,
Will give them a try and let you know the outcome...

Changing the bios setting has had no effect on DPMS..

Hmmm.......


Quote:From TomsHardware
Video Off Method: The DPMS (Display Power Management System) option allows the BIOS to control the video display card if it supports the DPMS feature. The Blank Screen option simply blanks the screen — use this for monitors without either power-management or “green” features. The V/H SYNC Blank option blanks the screen and turns off vertical and horizontal scanning.

The next thing you could try is the ACPI Suspend Type settings.
You could try S1 or S3 settings.
Changing this setting may not have any effect either, but it is worth giving it a try.

Edit:
Check if INVIDIA or AMD have Video Control Tools App for Linux.
Note: You'll need to check what GPU Chipset you have, and if either of the Linux Video Control Tools will work with it.

no results sadly..

Hmmm...........


Maybe try getting the latest Video Drivers?


Here is the NVidia Linux Driver Site:

Here is Linux® Drivers for AMD Radeon™ and Radeon PRO™ Graphics:

Yes I have. AMD graphics accelerator.
Thinking of swapping to Ubuntu as the problem does not seem to exist in that system for some weird reason.
