Ubuntu :: Failure To Wake Using Rtcwake Command?
Sep 20, 2010
I'm trying to wake my ubuntu pc using an rtcwake event and pm-suspend. I basically use the scripts in this thread: [URL] I have by now tried everything I could imagine to get the box to wake up, but it just won't. I have the latest BIOS version and a quite new pc (ASUS M4A78LT-M LE motherboard). The BIOS clock is set to utc, and RTC alarms are enabled there. Does anyone have any new ideas I could try? I'm pretty surprised I can't get this to work because the same scripts work perfectly on another pc I have (which is actually older).

I'm using "sudo rtcwake -m disk -s 5000" or whatever the seconds is for the time I need it. It doesn't help if I use mem. Anyone know what's up or know a better program?

Doeas anyon know if rtcwake is supported on Sun V100 running Debian Lenny? See my attempt at using it below.
SV100-1:/sys/class/rtc# rtcwake -s 30
/sys/class/rtc/rtc0/device/power/wakeup: No such file or directory
rtcwake: /dev/rtc0 not enabled for wakeup events
SV100-1:/sys/class/rtc#

Here is what happens. I type in "su", without the quotes, to switch to root. I enter my password.
Code: jon-Tuxbox:~$ su
Password:
su: Authentication failure
jon-Tuxbox:~$ It fails, and I get kicked back to the command line. I recently fixed the permissions on the shadows file and the su file in the bin directory, and that is what caused this. Before it would give another error. I tried resetting the password for root, but it didn't fix it.

The goal is to do:
sudo apt-get install Virtualbox
sudo apt-get virtualbox
sudo aptitude install virtualbox
ive tried all those combinations and they all shoot back the same reply:
sudo: apt-get: command not found
Every forum ive read says that my Fedora installed wrong and that i am screwed. Can anybody help me with this please?
Also does anyone have a link to download a free windows xp iso for virtualbox to run off of?

I have a netbook with a 150GB hard drive in it. A while ago I dropped my netbook and it wouldn't boot. Had a "failed command: READ FPDMA QUEUED" error at startup. So naturally I went and reinstalled. Reinstalling worked fine and I had my computer back. What I didn't account for was the fact that anytime it lost power and didn't shut down properly, I'd get the same error. I can't seem to recover my data either. Can't get any live disks to mount the hard drive after this error but for some reason I can still reinstall Crunchbang (essentially debian). Now I know there are bad sectors or something because when I try to use the disk that came with the netbook with an image of Windows XP that writes to the entire hard drive it throws an error but linux will avoid this I suppose when installing.
Now all of this is to say, being a laptop, several times I have left it on overnight when I fall asleep working or have to run into to town and it'll die and then I lose all my data, rather irritating. What's causing this error? What can I do to prevent it besides getting a new hard drive? If I can't prevent it from happening in the future is there a way to recover the data off the hard drive? Here's the section of the boot log that contains the error: [url]

I want to run a script on wake but it doesn't look like /etc/acpi/resume.d exists in Lucid. I tried creating it anyway, but I didn't have any luck. Is this because HAL has been removed? Is there a new method in Lucid?

I'm running Linux Mint 9 (aka Ubuntu 10.04 + a couple of tweaks), and my machine won't wake up from suspend.It hasn't done so successfully since Ubuntu 8.04. I'm running the default graphics driver (not the proprietary NVidia one) on a quad-core Gateway FX. How can I go about figuring out the problem?

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 am trying to conserve electricity and was looking for a linux WOL app that will allow me to remotely wake my windows 7 computer so I can stream music on demand. I have to believe this exists/is possible. I am also an idiot so if there is such a thing I'm going to need help getting it up and running.

I upgraded my old HP Pavilion desktop to 11.04 a few weeks ago and at first things were fine, but recently the PC refuses to wake up in the morning. I assume it's going in to sleep mode overnight, but no matter what I push on the mouse or keyboard it won't wake up. I have set both the PC and screen in Power Management Preferences to Never go to sleep, but it doesn't seem to matter and it sleeps regardless. how I can either make it not sleep, or sleep a little lighter so it wakes up without a hard reboot?

All I want to do is to be able to shut the lid on my laptop, have it go into suspend like it already does, but upon opening it again, successfully start up again. It'll sleep just fine, but if you close the lid and try to open it again later, the lights will indicate it is starting up, but the screen won't initialize, and I am left with a blank, black screen.I've tried a line of code to enter into my menu.lst file, and it seemed like it should work, but it borked my computer and I had to manually reinstate the line of code it had before.

I have managed to make ubuntu (9.04) turn itself on from being completely off with the following code:
Code:
sudo sh -c "echo 0 > /sys/class/rtc/rtc0/wakealarm"
sudo sh -c "echo `date '+%s' -d '+ 480 minutes'` > /sys/class/rtc/rtc0/wakealarm"
[code]....

I have made a virtual machine on my server using virt-manager that I access using virt-viewer from my desktop/laptop. Currently I am having to leave the VM on all the time. Which is a waste of cpu/ram etc. Ideally I would like to be able to wake the vm up from virt-viewer or from a bash script being ran on my desktop.

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 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 have a macbook5,1 with ubuntu 9.10 on it. Does anyone got wake-on-lan working on this type of machine (or any other intel macbook?)
At startup, ethool sets the wake on lan parameter. I tried sending the magic packet with the wakeonlan utility.

For some reason when I wake my computer up, there is no sound. No matter what I try through the terminal, or by playing with the volume controls, no audio. I can only get audio working again by a restart.
Does anybody know why, and/or how to fix?

I'm trying to get WOL to work on my web server built on an ASUS P4A800D-X motherboard (which supports wol).I have it enabled in my BIOS and I've tried several different tools with no results, including my dd-wrt based router which has this functionality built into the firmware.All the guides I've read say it has to be enabled in the driver settings in the Windows Control panel before it will work, but I'm running Ubuntu Server 10.04.
Is there any special steps that must be taken in the OS to enable my web server to power on from the LAN? I've never used this feature before and would like to just shove my web server in a corner some where and have 100% remote control from my main PC.

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!

My computer runs really well when I first switch on, and usually I'll leave it on all day, and just suspend it when I'm not using it.But since a couple of days ago, it's been playing up after waking from suspend. Everything slows to a crawl, and the system monitor shows the CPU working at 96-100% permanently, even when I'm not doing anything.It's not like I even have many apps open. Generally I'll have a few tabs going on Opera, have Thunderbird open, and Gwibber. I'll open and close gedit and gimp as I need them, and that's about it. Having said that, this new version of Thunderbird seems very slow to me compared with the previous one.

I'm running Ubuntu 10.10. Is there a way to eliminate, or at least change the length of time, of having to enter your password after the screen timesout from no activity? I've looked all though Preferences but have not found anything that seems to address this.

I am having a problem with a slow wake up from the hibernate in karmic with gnome.My desktop has 2GB of ram and 4GB of swap.m doing standard hibernate from the menu.Hibernation takes 44s, which I can live with for now. But wake up measured from grub boot menu to unlock dialog takes 2m 47s. I think it's reasonable to expect it to take less than a minute.
