Ubuntu :: Stop The Display From Going To Sleep?

Aug 11, 2010

I just recently changed one of my OSs to Ubuntu 10.04. I have run into a somewhat annoying problem. The problem: My monitor is going to sleep after 10 min. of inactivity no matter how I have the system set. I do not wish for this to occur, I mean why bother having a screensaver? lol I am using a desktop PC. The Power Management daemon is enabled. I have power management set to - Put computer to sleep when inactive for: Never Put display to sleep when inactive for: Never When power button is pressed: Shutdown When suspend button is pressed: Suspend

I have screensaver set to- Activate screensaver when computer is idle: unchecked Lock screen when screensaver is active: unchecked The duration slider is maxed out to 2 hours. The sleep function of my monitor is turned off. It's a Compaq WF 1907. I know it's Ubuntu because my monitor OSD is showing a "No Signal" message when it happens and it never happens when I am using Linux Mint 9. Since LM9 is built on top of Ubuntu, this leads me to believe a setting is simply not taking. Ubuntu is fully updated. I have a wonderful desktop set up and I would really hate to scrap it and go back to LM on this partition but this is really irritating. Is there some way to make it work the way it's supposed to?

Ubuntu :: Display Going To Sleep?

May 14, 2010

How can I stop my display going to sleep?

I've got the Power Management settings for mains power as:

Actions - put computer to sleep when inactive - never

Display - put display to sleep when inactive - never

Screensaver settings are:

Regard computer as idle set to 2 hours

Unticked Activate screensaver when computer is idle

Yet the screen still goes blank after a few minutes when I'm not using it.

I dual boot and it doesn't do it in Windows. It didn't do it in 8.10 or 7.10 either.

Ubuntu :: Put Display To Sleep Via Key?

Oct 28, 2010

My display is set to sleep after 30 minutes of inactivity. When I go to sleep at night I don't want to wait 30 minutes for the monitor to shutdown, is there any way I can use the keyboard (like a hotkey) for :

1. Start my screensaver (when I go for 5-10 minutes afk for example).

2. Make the monitor go to sleep mode.

Ubuntu :: Maverick Display / Computer Sleep Despite Being Set To Never

Oct 20, 2010

I applied Power Management settings to put my computer to sleep in the hope that it would only sleep when it wasn't downloading something in Deluge. Unfortunately it would seem that it puts the computer to sleep despite Deluge being active. No biggie I thought, I'll just disable the sleep settings my setting them both back to NEVER. However, it ignores my new settings and still puts the display / computer to sleep, at the exact times I set originally!

Fedora :: Display 'sleep' Ignoring User's Settings?

Aug 8, 2011

installed Fedora 14 on my desktop a couple of days ago. For the most part, it seems to be fine, but I've got a problem with the 'put display to sleep when inactive for' setting. From the desktop, I've tried going to system/preferences/power management, where I've set the display to go to sleep when inactive for 30 minutes - however, it instead goes to sleep after five minutes. The same applies whether I set it to 10m, 30m, 1hr or never.

Having looked online, someone mentioned gconf-editor as a fix to another issue, so I decided to give that a try as well. Under /apps/gnome-power-manager/timeout, I tried setting sleep_display_ac, sleep_display_battery and sleep_display_ups each to 1800 ("The amount of time in seconds before the display goes to sleep" - 30mins, by my maths) on the off-chance that the OS had incorrectly detected the power source, but the display again went to sleep after five minutes.

If it makes any difference, I'm not using a screensaver, and I think the kernel I have installed is 2.6.35.13-92.fc14.i686 (that's what's given in System Monitor). I've also tried running yum update, again just on the off-chance it'd fix something, but everything is up to date.

General :: Display With No Signals And Go In Sleep Mode After Update

Jan 24, 2010

Linux downloaded new updates and worked perfectly. Next time I started mint, just before the login screen appears display says No Signal and goes in sleep mode. I think that mint downloaded somekind of display driver update wich is not compatible with my driver card. I can't see desktop, I just hear the login sound and that's all. What should I do? I'm new with linux.

General :: Stop From Re-setting The Display Brightness?

Mar 16, 2010

After manually setting the display brightness on my laptop, the system re-sets the value. If the laptop is plugged in, the value is set to full brightness; if it is not plugged in, it is set to dimmer. How do I stop that behavior?

Note that I am not talking about what it does in response to the event of plugging in or unplugging my system. It changes on it's own - usually several minutes after I change the brightness value. I have observed this behavior on different systems, different distributions, and different desktop environments.

Fedora :: Screensaver Doesn't Kick In Or Display Doesn't Suspend/sleep?

Jul 25, 2009

Anyone noticing intermittent problems with the screensaver not kicking in or the display not sleeping? This is in gnome under F11.I have the Power Management Preferences set to put the display to sleep after 30 minutes of inactivity and gnome screensaver is configured for 5 minutes idle time.On a regular basis, I'll leave my computer come back anda) the screensaver hasn't kicked inorb) the screensaver kicked in, but the power management features didn't kick in to put the display to sleep.It seems to be an intermittent problem and usually it goes away after I restart X, but then at some point it comes back. In the past, I've gotten in the habit of being logged in for weeks/months at a time but I find that I can't go more than a few hours without logging out and back in or else the screen won't go to sleep.

OpenSUSE :: 11.4 Gnome 2.3 Display - CRTC Error That The Display Is Over The Maximum - 1920x1920

Apr 16, 2011

I have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).

I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.

I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.

Fedora :: System-config-display Just Ruined Display?

Jun 29, 2010

I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?

General :: X11 Forwarding - Error: Can't Open Display: <ip Of Display>

Jun 28, 2011

I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:

From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0

I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:

From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>

I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.

I get these error messages: Error: Can't open display: <ip of display>

Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.

Ubuntu :: Switch Off The Sleep Key

Jul 20, 2010

I have Kubuntu 10.4 cleanly transformed to Gnome (aptitude task kubuntu-desktop was removed and ubuntu-desktop installed). I want to switch off the sleep key, because I sometimes press it accidentally and the computer goes to sleep. Fortunately the sleep is correct, no applications crash, but still some network connections goes away and it is annoying and time wasting. I tried to switch it off with the power management tool, but there are only two options: sleep to memory and sleep to disk. I am sure, there was "do nothing" option in some other versions, but it isn't there.

How can I fix it? Is it possible to hack it with some "edit gnome variables directly" tool? I am experienced linux user, but not a gnome or X expert, and I don't like to solve simple problems (and I think this is a simple problem) with complicated scripting and strange hacks.

Ubuntu :: Sleeps Again After Returning From Sleep

Feb 2, 2010

I configured Dell Latitude D620 to go to sleep mode (suspend to ram) when i close the lid. It suspends ok and then I open the lid. It wakes up ok, but few seconds after goes to sleep again! So I need to press the power button to force it to wake up.

Sleep button works just fine. /etc/acpi/sleep.sh from console too.

/etc/acpi/events/lidbtn

Code:
event=button[ /]lid
action=/etc/acpi/sleep.sh
update:

I noticed that it always goes to sleep again when I wake up laptop by opening the lid. For example if I run /etc/acpi/sleep.sh, pm-suspend or press the sleep button laptop goes to sleep, then i close the lid and when i open it back - the problem occurs.

Ubuntu :: Wake From Sleep And/or Hibernation?

Mar 1, 2010

I'm running 9.10, how do I wake up from sleep or hibernation on my Dell XPS notebook? I have no problem putting the comp to sleep/hiber but can't seem to work out the keys to wake it up again.

I don't get any responses from the keys even when I try CAPS LOCK or NUM LOCK, so all I can do is reach for the on/off switch.

Ubuntu :: Monitor Goes Into Sleep - Won't Wake Up

Apr 27, 2010

I am running Ubuntu 9.10 on my desktop and everynow and then I get this annoying problem. If I walk away for a bit, just upstairs to use the bathroom, sometimes when I come back the monitor is off and the power light is blinking. You know, like what monitors usually do when they are still powered on but the screensaver is done playing. However, this happens to me well before the 10 minutes that the screensaver is supposed to end.

It does not always happen, and I can't really isolate what may be causing it, as I never take a note of what I'm doing when I go pee. HOwever, I rarely do anything other that run VLC, Chrome, Firefox, or OpenOffice Writer.

The problem is that the screen won't wake up. Moving the mouse does nothing. Jamming some keys does nothing. Trying to go to text terminal does nothing. I have to either REISUB or hold down the power button on the tower.
