Ubuntu :: System Not Booting (Strange Power Save Mode)
Jul 31, 2011
Out of nowhere my computer will not boot up. I get the message like this
NMI received for unknown reason 29 on CPU 0.
Dazed and confused, but trying to continue
Do you have a strange power saving mode enabled?

I have a Dell Precision T3400 workstation (Nvidia Quadro NVS 290) with the kmod Nvidia driver installed. Everything works fantastic for power saving, the screen saver comes on , then the monitor blanks after a while. The only problem is that the monitor itself (Dell E228WFP) never goes into standby. The power LED stays green instead of orange. Worked fine under FC8, only noticed it recently under FC10.

when my monitor turns off after 30 minutes, I cannot do anything after. We're talking complete lock down of Ubuntu 10.04 64-bit. Not even alt+printscreen+REISUB reboots the machine; I have to do a hard reboot (which sucks and is hard on hardware).

I have a server that only runs durring the hours the house is asleep, to avoid bandwidth hogging. I know there are ways to prevent bandwidth hogging, but I figured I'd kill two birds with one stone. My other goal is also to reduce power and cooling costs. My two computers between them make a very nice space heater in the winter, in summer they make it sweltering in my room.I'm sure it would be trivial to get the sever to power itself off every morning, but is it possible to get it to power itself on at bedtime? If not, I do have Wake on Lan working, is there a windows program that would allow me to send a wake on lan signal every day and then shutdown windows

I want to switch off 3d i.e. dri on my laptop to save power. There is a bug in the intel video driver that makes it generate excess wakeups and thus increase power consumption. I don't use 3d so this is very annoying.
I have tried modifying /etc/X11/xorg.conf to insert an "NODRI" option in the "Device" section and have commented out both of the "load dri" commands in the "Modules" section. No go. When I look in the xorg log, these changes are seen but not acted on. The system appears to have hardwired defaults set somewhere which are difficult to override. It appears to be a new issue because with Karmic one still had control with xorg.conf.
Just generally I don't like changes like this because it is not documented on the wiki where and how to change the defaults in Lucid. Linux was supposed to be easily configurable so IMHO this is a step backwards.

I have created a custom linux distro originating from the ubuntu server edition and have slim as the login manager, and openbox as the window manager. When it goes into power save mode and turns off the monitor and I move the mouse to wake it up it just goes to the shell with a mouse cursor on it. How can I get it to go right back to the openbox window manager?

I'm not sure this belongs in this forum as opposed to the hardware forum, but I do not beleive this is a hardware issue.I want to stop the scrren from blanking and going to power save. I'm running 5.3_x86-64 and I'm using the nVidia drivers direct from nVidia called NVIDIA-Linux-x86_64-96.43.13-pkg2.run.
So far, I'm added DPMS off in /etc/xorg.conf, removed all the screensaver packages and all the power management packagesbut the screen is still going blank after a time of inactivity.What else do I need to do? I can not allow the screen to go blank, there should be no screensaver or power management and the machine should stay in a completely awake and ready-to-use state at all times.

I recently read that windows 7 has come with a special "power saver" mode which will ensure your computer does not take up any more electricity than you needed ( Control panel -> system -> security -> Power options & select power saver power plan) , Does ubuntu have this feature ?

I've re-set my password in recovery mode: now how do I save my changes and exit to a normal boot up ie to my desktop? Right now my screen shows "username@Username-desktop:~$"
I've also done a sudo apt-get updates and sudo apt-get desktop for good measure. But how do I get out? If I force quit the change is not saved and I cannot log on.

I'm on 10.10 64 bit. I have my power management settings configured so that on AC power, after 0:30 the screen is supposed to go to sleep.
But the problem is that it never goes to sleep. The screen saver comes on after 10 minutes, as scheduled, but when I come back even after a long period of time, the screen hasn't gone to sleep (it hasn't gone into low-power mode).
Please let me know what specific config information I should provide to help debug this and I'll post it here.

So the power went out at my house recently, and my home theater PC seems to have taken a blow. We had it on a surge protector, which didn't blow so that's fine, but it keeps telling me its in low graphics mode, and I can't seem to fix it for the life of me. I could reinstall ubuntu, but I have a bunch of movies and music on that drive that I want to keep.

Ok so I am a total newbie at Ubuntu Linux and I'm having problems I don't know how to solve.
1.) Up until yesterday this wasn't a problem, but after a power outage while I was connected I am now unable to connect to the internet anymore as it says "Networking is disabled", how do i enable the "networking"?
2.) Another problem I am having is that I am not able to dim the screen in order to save power among other uses, I've looked around but haven't been able to find a solution, I am running ubuntu on a Gateway M-Series Laptop.
3.) Finally, since installing linux I have been unable to listen to music or any other sounds through headphones or speakers, when i connect something into the audio output, the outer speakers do shut off but no sound is emitted through the speakers/headphones, and yes i have tried multiple ones to make sure it wasn't the headphones or speakers.

I attempted to install Catalyst 10.11 for my ATI HD 2600XT and the system now only displays lines and a large block of pixels where the mouse would go. CTRL-ALT-F1 kills the system and does not provide a command prompt. This is a single installation, not dual-boot, but there is no Press Esc to access the Grub menu during startup so I cannot choose safe mode. I attempted to get into Recovery mode using the flash drive that I used to install the system and it tells me there is no Recovery kernel (I used the 64-bit Desktop installer, not alternative). Does anyone know an alternative to get into the Grub menu other than ESC during bootup? Alternatively, do I need to download the 64-bit Alternative ISO and create a new boot disk with it so I can access Recovery mode? Is there something else I'm not thinking of?

Whatever settings I use in the power manager, (Ubuntu default Gnome Power Manager) nothing appears to change. Screen brightness does not change when moving the slider, but is reduced after 5 or 10 minutes (haven't timed it. Probably whatever is default) of inactivity, even though the reduce screen brightness checkbox is unchecked. The latter is pretty annoying when watching online TV streams, especially since the video also exits full screen mode when the screen brightness is reduced.
The weird thing is, as the title implies, that when booting in recovery mode with FailsafeX the power settings seems to work. At least the screen brightness varies as the slider is moved I should probably mention that it is possible even in normal mode to adjust the screen brightness by using the buttons for adjusting screen brightness on my laptop (Fn + arrow up/down)

I work on Ubuntu 9.04 and our application requirement is not to go to power saving mode when application is running. I added ServerFlags section to /etc/X11/xorg.conf
Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
EndSection
This didn't help. Then I tried following commands
gconftool-2 -s /apps/gnome-power-manager/ac_sleep_display --type=int 0
gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false
I see that it works fine only if I change settings via Settings>ScreenSaver>Power Management in gnome. I wan to do this via script. Can I do this? Which file gets updated when I change display settings via Settings>ScreenSaver>Power Management.

I have just installed Ubuntu in a Windows Vista system. The installation seemingly went fine. After installation, system restarted to boot menu (grub?) where I selected Vista. Vista started fine. I restarted the pc from the Vista login screen. Now the problems started. At grub, I chose Ubuntu. It began to start up, made it through the Ubuntu logo with the dots, some splash screen or wallpaper came up and *bam* the computer powered off. Next I Wanted to boot Vista again. Grub came up for a half-second before power-off.
I tried to boot from the CD again to see about repairing grub or just reinstalling. The installer ran for a second before power-off. Next, tried BIOS boot manager to boot from the HDD again. Powered-off at the BIOS boot manager screen before I could choose where to boot from. Twice in a row. Tried to boot into BIOS to check settings for anything odd. Powered-off within 1 second after I got into the BIOS. Finally, I would hit the power button and it would turn on and then power-off instantly.
I unpulgged my Logitech VX Revolution mouse and the charger (it's fully charged and holding fine). I thought maybe the computer was hot (feels normal though), so I waited one minute. After that, I was able to boot from Grub to Windows fine. I restarted the pc from the windows login screen to try Ubuntu again. Got into grub and just repeated the same process from before with the same results. Nothing works. I waited one minute again, and I was able to boot into Vista fine. I am posting this from Vista with everything connected and working fine.
I downloaded the 32bit desktop version from the "enhanced download page." I burned the iso with the Toshiba DiscCreator software that came with the computer. I've used DiscCreator many times before with great success. Ubuntu was burned to a normal 80min/700mb Maxell CD-R. I'm afraid to reboot from Vista now and find that one of these times, I won't be able to get back in. I installed Ubuntu into an empty 9.77gb partition and formatted it as ext3. Used an empty 1.46gb partition as swap.
Here's my setup:
Code:
Satellite A215 Detailed Product Specification1
Model Name: A215-S5837
Part Number: PSAEGU-03801J
UPC: 883974072095 .....

All of a sudden today there was no display on my Ubuntu PC. It seems to be powering on - I get the LG screen when the monitor is switched on - but it goes into "Power Saving Mode". How do I diagnose this? I already unplugged and plugged. Monitor is connected to a graphics card - no change when I switched to VGA.

I have a new Lenovo (thinkpad) x100e laptop. I've recently installed the new Ubuntu 10.02 distro and have found the oddest bug. If my power cord is disconnected (i.e. if I'm running off battery power) then the login window locks up. Conversely, if the power cord _is_ connected then things work as usually. (Also, trying to adjust brightness causes a crash --- but I suspect that this is not odd). Where I should put this information.

I recently converted a Toshiba Satellite A75 notebook with a broken screen into a minecraft server that me and my friends will be using at UAB. It's currently running the latest version of Debian in text-mode with a few shell scripts that backup files and update a webpage at specified times.
The server runs fantastic ( though it's currently on my home network so no one can join it unless they are on LAN ) but there is a minor problem. I took a look at the backups from last night and it seems the server shut down around 10:00 in the morning because the laptop went into sleep/hibernate mode or something like that. I'm not sure what's causing this exactly but I think it's some setting in gnome-power-manager, but I can't run it in text mode.

I am struggling to get Debian 8 stable to boot on an apple powermac g5. I installed using guided partitioning, and chose the all on one partition scheme. I am able to select the Debian hard disk from the boot drive selector from mac. I get to the first stage bootstrap, press L for Linux, and then it simply redirects me back to the drive selection. However, after I'm redirected the colors are messed up.

I have 3 old power supplies, each 3+ years old (out of warranty). One just blew out after a power failure, but it was on a beefy 750 kVA ACP uninterruptible power supply / surge surpressor. It just won't boot a 939 motherboard, but I can not find anything wrong with it. I short the 3rd and 4th pins to turn them on and check many of the pins. They are all ~exactly at nominal voltages. It is as though I forgot to plug in the ATX 4 pin, 12 V cable, but I didn't. Strangely enough, they all boot a very old Athlon XP (32 bit) single core processor on an AGP motherboard. I don't have a good setup to load test them. Is there any trick to rescue them? A fuse inside? Hotwire wire 4 to wire 8? I hate to throw them away as they are nice, quiet, high power supplies:
Antec Neo 480 W
Enermax Liberty 620 W
Enermax eg651p 650 W
Perhaps, I could charge my car battery with one? Install 12 V lighting? Electrolosize water and start an Oxygen bar?

I'm not exactly a computer pro. I had copied Ubuntu netbook on to a USB with the program given at Ubuntu.com. I plugged it in and booted it via F12 on my Alienware M17x and I chose to try it. When I selected to try it, it wouldn't work at all and I sat there for about an hour. I turned the laptop off, and now it says I'm "Missing" the OS. Which means my Windows 7 is gone.
My friend had told me to do something with Gparted, but it didn't help. He did say that my files could possibly still be there (which would be AMAZINGLY awesome. I just wish I could get things back to the way they were yesterday. I need to know what is wrong with the partitions though, since I think that the errors are related to the partitions. It is a Solid state drive. My priorities are:
1. Save my files (if they are there still) to an external HD
2. Re-install Windows 7 (if needed)
3. Install Linux alongside Win7

I am running a version of Ubuntu 10.4 with XFCE loaded (actually Qimo, a distribution for kids). I am using a pci wireless card with a broadcom 43XX chipset and WPA2 authentication using the Broadcom STA driver. In an account with privileges I set the auto eth1 (which is what my wireless card comes up as) to connect automatically, and make available to other users.
When I switch to the kid's account, the wireless connects just fine. Then, if the computer is not used for a period of time, the powersavings mode kicks in. When the computer is woken up, the wireless connection does not attempt to reconnect. If you right click on the networking icon it doesn't even show any available connections, even though it can be found by clicking edit connections. The only way I can get it to reconnect is to restart the machine (I will admit that I did not try to restart the networking service, I will try that tonight).
Any ideas? This has been driving me nuts for a few days now. The users during the day are non technical and can't deal with these kind of issues. I can post more details about the setup (as recommended by the sticky post) tonight. I am at work at the moment and can't get to the machine from here - because it has removed itself from the network again.
