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.

I just recently got my old box back and now I'm running 10.4. I've had some minor issues that I have got through but now there is one which seems to really be frustrating me. At any random time my monitor may go black as if it is in sleep mode. The problem is when it does this, no mouse movement or keystroke will wake the thing up. So I am forced to press the power button. When I press the power button the Ubuntu logo pops up on the screen as if it magically woke up but it is too late because now the computer is shutting down... When I go to System>Preferences>Screensaver I get to the options for the screensaver and I have about 2 seconds before that triggers the screen going black.
I can't even start until I know that my screen won't shut off at any random moment!

This morning I woke up and while my computer was turned on, I couldn't wake my monitor up from "sleep". So I turned off the computer and turned it back on. I noticed that the normal boot screen (which usually shows a monster truck from Abit) was pretty severely distorted.Basically all output to the screen is so distorted visually that I can't tell what's going on. I've attached two images that I took below:
The first image is at the very beginning of the boot (perhaps when the monster truck should normally show <- sometimes it shows and sometimes it is just too distorted to tell anything). The second image is after it's been on for about a minute, and you can see a little text box giving me some sort of warning (which I of course can't read). I can click "OK" or something along those lines by using they keyboard though and progress to a new warning box, but again, can't read what they say. How can I figure out what the problem is?s it definitely a videocard thing, or could this be caused by anything? I don't know if it's a software problem (running Ubuntu 10.04), or if something went wrong with my hardware overnight.

Whenever I close my laptop lid or just press the suspend button, it will go to sleep just fine. Perfect. Waking up is the problem. The drive light flashes for a few seconds, and then it just goes to back to normal but my display is still busted.

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.

I'm having some trouble getting Ubuntu Netbook Edition to work properly on my Netbook. If I close my netbook for long enough for it to go asleep, which only takes 10-20 seconds, then when I open it back up and press the power switch, nothing appears on the screen.

I have an interesting issue. I have a computer running Ubuntu 10.10. I have a wireless USB Microsoft keyboard attached to this, and I have a cheap USB infrared remote also attached to it.The wireless USB Microsoft keyboard can wake up the system from suspend. The USB infrared remote cannot.To start off, I made sure my /proc/acpi/wakeup had wakeup enabled for all usb devices.
Code:
xbmc:~$ cat /proc/acpi/wakeup
Device S-state Status Sysfs node
[code]...

I have installed Debian 8.1 with KDE desktop on Lenovo t431s with intel HD4000 graphics.
When using it with dual monitor configuration, I experience the problem when I put system to sleep (by closing the lid), then remove the external monitor cable (from miniDP port) and then try to wake system from sleep. The login screen freezes and I am unable to move the mouse or type in credentials. In case I had music player running I can hear the music after system wake , but it shutters while playing.
This does not happen on some other distributions, but the problem is that I very much like my current setup and I would like to fix this problem and keep it.
I do not know if this problem is due to KDE or KDM or it's Debian base.

I've configured my F12 system to go to sleep when idle for a period of time and so far everything has been working out well except that it appears that the USB ports are completely dead with the system is put into sleep. I can't wake it using keyboard or mouse. only with the power button. Anyoen else experience this or know how to allow sleep from keyboard/mouse?

Firstly, wol works fine from shutdown and hibernate; it's just suspend which doesn't work.
I've got 2 types of workstations, all running 11.1. They both have this kernel:
2.6.27.45-0.1-default #1 SMP 2010-02-22 16:49:47 +0100 x86_64 x86_64 x86_64 GNU/Linux
Type 1 is a dell optiplex 745, bios version 2.4.1. Here's the relevant bit from lspci:
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5754 Gigabit Ethernet PCI Express (rev 02)
Kernel driver in use: tg3
Kernel modules: tg3
[Code]....
The fact that it's happening across two different machines makes me wonder if it is some OS setting I've missed, but then maybe neither card/driver supports it from suspend.
I'd really like to get them waking from suspend because training users to use suspend rather than hibernate would be a pain. Also, being able to configure such that it only wakes from suspend and not hibernate/shutdown, as implied in the bios, would allow me to wake machines up for backups etc only when the users are here, rather than on holiday/seconded to another department etc.

My laptop won't wake from sleep. I hit the powerbutton and it'll blink a few more times, turn green and the keys will light up but the screen stays black.
Running sony vaio s with windows 7 and 11.4 duelboot. I really need it to be able to suspend and wake because I'll be taking it to college in the fall.

Is there any way to find out which device/event caused Ubuntu (10.10) to wake up from the most recent sleep/hibernation? I am trying to troubleshoot some sleep issues on a new box, and knowing what's causing it to wake up would help. I did check /var/log/pm-suspend.log but all it seems to say is Sat Dec 11 22:18:27 GMT 2010: Awake.

I have set up a hdparm configuration file ( /etc/udev/rules.d/50-hdparm.rules ) with :
Code: Select allACTION=="add", SUBSYSTEM=="block", KERNEL=="sda", RUN+="/usr/bin/hdparm -B 255 -S 0 /dev/sda" .
This works correct when I power on my system, however after waking my computer from sleep mode , /dev/sda appears to operate with APM .
Is there a way I can make this setting to be persistent ,i.e. APM disabled when waking up from sleep mode?
I am running Debian Jessie x64.

I have openSUSE 11.4 KDE (upgraded to Tumbleweed but that's not relevant here). The computer is a Dell Optiplex. My sleep (suspend to ram) and wake (restore from ram) work very well. The box can multiboot to windows 7 as well as to Linux.
In Linux, the restore process is triggered by pressing the power button on the front of the case. No other action will bring it awake.
In windows, the restore process is triggered by the power button but also by moving the mouse or touching the Escape key, spacebar etc.
Here's the question: how do I get the computer to wake in Linux by activating a key (or mouse, whatever) instead of just the power button (which is under the desk and hard to get to)?

I have Ubuntu 10.04, and I have my power settings set so that my display is never supposed to go to sleep, yet it still does after 10 minutes of being idle. Has anyone else had this issue?

I am trying to install Ubuntu 10.04 on my PC using NVIDIA GeForce 9150LE graphics and HP w2207h monitor. After using the Wubi installer and rebooting my computer, i select the ubuntu boot menu option and it says it is preparing to continue with the installation. after a countdown before it begins, my monitor goes to sleep. i used an eMachine monitor that i used in a previous installation of 9.10 that worked fine and reached the exact same problem. When booting from a live CD and selecting try without installing the screen comes up with a blinking underscore, and both monitors went to sleep. I believe its a problem with the graphics chip, but i dont know how to fix it.

Whenever I boot into ubuntu 10.04, my monitor just automatically goes into sleep mode. As soon as I select to boot into ubuntu, the monitor just sleeps. There's no getting out of it. Booting into windows works fine though, so the problem has to be ubuntu.

I've been using Ubuntu for about a month now, gotta say I'm loving it. I've been spending more time in Ubuntu than W7 now. I've been trying to get Steam to work with Ubuntu without the whole thing exploding on me. I've got WINE and winetricks already pretty much set up, and Steam works flawlessly. The problem appears when I try to launch Team Fortress 2. The monitor instantly goes to sleep, but if I wait a few seconds, I can hear the in-game music, which means that the game is loading correctly.
I'm using the 10.04 LTS release, Wine 1.1.42. Kernel version 2.6.32-22-generic. My graphics card is a Radeon HD 4850, running Catalyst 10.5.

infact im kinda of a "pre-life" Ubuntu user I have burned a CD-R disk with the ISO image of Ubuntu with infrarecord however... When Insert the disk and boot a screen pops up and I press enter then the language thing comes up and I select english but here is where the problem is, Its seems that for only a few seconds I can control my keyboard then it stops working...So everytime I try to click "try Ubuntu without install" I cant and it just sits there
after it sits for maybe ten seconds it looks like it is rebooting but then it says "Monitor going to sleep." and if I try to turn it back on its just a black screen. Also if I like Ubuntu (which I probably will) Im going to run a DBAN and install it from scratch and I dont really want any problems :/

My monitor falls to sleep when I get to the Grub Menu and choose "Ubuntu". It will get to the purple-ish loading screen to a minute before the monitor falls asleep. I am using 10.10, and this is my first experience with Linux. As much details as I can think of: I recently installed Ubuntu 10.10 after playing with it on a live CD. I chose to install it alongside Windows 7. The install was quick and smooth, and booted up as it should. When I get to the GRUB menu, I had more choices than I thought I would (I figured I could nix them later.)
These options were:
Ubuntu Linux
Ubuntu Linux (recovery mode)
Memory Check
different Memory Check
Windows 7
I chose windows 7, to make sure ol' semi-reliable, slow, and resource hogging OS worked. As expected, it ran through some stuff white-text-black-screen stuff to make sure all it's files were there (probably due to the fact I had to give some of my hard drive space to ubuntu). As far as I could tell, this did not modify any files, and it checked out with windows. I restarted using windows at this point....

Ubuntu 10.04
Under Preferences > Power Management I have changed the settings to never put the computer to sleep and never to put the display to sleep.
My display still goes to sleep and I am prompted for my password when I leave the computer unattended.
I would like to be able to hit the "Lock Screen" app I added to the top panel to lock my screen, but otherwise I would like it to just stay on.

I can't get debian 5.0.4 i386 to load I can get as far as root for crash repair during boot-up but much further than that and my monitor turns off. Ubuntu 8.04.4 live cd (kernel is 2.6.24 i believe) works but says I have to enter noapic in the boot string. APIC is on and greyed out i.e. not accessible in BIOS --- might be non-compliant Only thing I can think of is to add acpi=off in GRUB entry but the change doesn't seem to work or take effect. I added it to the relevant entries in menu.lst in grub and it still didn't take effect. Grub must be getting its config info somewhere else...

I'm not sure, but I think this is hardware. Anyway, I have two different boxen running FC14. One has a Nvidia 9800, the other a Nvidia NV96. The former I use as a desktop, the latter a server. I've let the server go with whatever the system autodetects for video, but the desktop I've played with a ton: nouveau, nvidia, etc.
Anyway, since I upgraded both to 2.6.35.9-64, both go to sleep at some point during rhgb. I can't find anything in boot.log, messages, or what have you to try. This happens even if I go to runlevel 3, so unless I'm misunderstanding the boot sequence, this is way before X starts.
Now, just upgraded to 2.6.35.10-72 tonight, and the behavior slightly changed. Before, it would show the rhgb loading screen for a few, but then the monitor would sleep before it completed. As of this kernel, it just goes to sleep right away.
The only quirky thing I can think is that I'm running DVI out into a KVM. I have been making sure to have the machine as the active video when it boots, so it should still be able to feed EDID info to the machine, but I did notice when trying to track down nouveau/nvidia problems on the desktop that X was having trouble reading my EDID all the sudden.
I'm assuming there's some automagic default now that's putting my monitor out of range. The only way I've been able to keep the desktop running is to not have the nvidia driver installed, but also not have a driver type specified in xorg.conf. If I do that *and* specify a modelines, I can boot with rhgb off at runlevel 3, then manually start X. From the Xorg.0.log, it appears to be falling back to vesa, which is the only thing that works.
How can I debug this? If the monitor sleeps but there are no messages in boot.log, messages, or Xorg.0.log, how can I even figure out what rhgb is doing?

Running openSuSE 11.3 w/ a KDE 4.x desktop. Every time I'm using KTorrent, when I come back into the office and "wake" the monitor, I find KTorrent has crashed and I have to restart it. So I'm guessing that KTorrent is crashing either when my monitor goes to sleep mode or when I'm waking it up. I've tried changing some settings but when the system is running, I cannot seem to access the monitor control panel. Pressing the menu button on the side of the monitor does not bring up the monitor menu. There used to be an easily noticed "Desktop Settings" in KDE 3 but I'm not finding the equivalent in KDE 4. How to keep this Samsung SyncMaster 997DF 19" CRT from going into sleep mode?

You know that glitch where your monitor doesn't come back after switching off for power saving? That's gotten WAY worse since switching to Lucid. It used to happen every other day or so, now it happens 2-3 times a day. Songbird used to keep it from switching off on Karmic, but Songbird doesn't work on Lucid so that's out the window.
Also: as similar error happened when restarting after the glitch happened this latest time. Ubuntu started running its routine disk check and I hit C to skip it. The screen went down like it does in the Monitor Sleep glitch. I reset again, it did it again. Eventually, I just let it do the check. This has NEVER happened before.

I'm running a fresh 10.04 x86-64 on a thinkpad w500, using the default video driver. The monitor shuts off randomly, sometimes while I'm using it and requires me to trigger sleep mode and waking up to bring back the screen. When it shuts off, everything else seems to be running. (i.e. its not going to sleep) I've turned off screensaver, sleep, hibernation and installed the Caffeine util to no avail.
