Ubuntu :: Computer Freezing Up - Requiring Power Off

Mar 30, 2010

This computer freezes, requiring power-off, somewhere between 2 seconds and 2 hours after boot-up, most every time I use it. Sometimes I've had to power-down perhaps six times in 10 minutes. When it freezes I have a movable mouse-pointer that can select nothing. Right-
click does not operate. I don't seem able to isolate a single cause. I ran a RAM check with no errors showing. Matters not which version of Ubuntu I choose when booting. I've replaced mouse and keyboard. Only running 256 meg of ram and do plan to

Ubuntu :: Window Goes Blank At Random Requiring Restart

Jul 15, 2010

I have just installed kubuntu 10.04 (64 bit) on a moderately new Lenovo R500 laptop (dual-booting with Windows XP).

Problem: several times per working day the screen goes blank. It remains backlit, and I can still hear music or games if they were running beforehand. The only way I have found out of the situation is a full restart.

The problem occurs somewhat randomly, but is usually associated with movement of the mouse. Switching to a new user often causes the problem. Sometimes the screen freezes for 1 second before going blank. I have tried messing with the screensaver settings and the permissions for libusb (which are flagged in the mouse system settings page) without luck.

Ubuntu Networking :: Wireless - Constant Connection Drop Offs - Comp Freezes

Oct 19, 2010

I've been using a Netgear WG311v3 wireless card to connect to the internet successfully since 8.10. However, since 10.04 I've had some serious issues with this card (at least...I think it's the card). I updated to Meerkat hoping that the problem might fix itself, but it's still there. Here's the situation: The problem most often occurs when I'm running Transmission, but also Firefox. It also happens when streaming videos to my xbox via uShare...basically, any time I'm using the internet.

Suddenly, my download in Transmission will drop to 0.0 KiB/s or in Firefox, pages will stop loading. If I close and try to reopen Firefox, it tells me the process is already running. If I try to restart, it says firefox-bin is still running. I click reboot anyway, and the computer hangs indefinitely at the purple Ubuntu shutdown screen. The terminal also freezes if I try to run any commands that are wireless related, for example iwconfig or ifconfig. I have to close the terminal to kill the process.

I've also had more serious crashes when running Transmission where absolutely everything freezes and a hard reset is my only way out. Forgive my n00bishness and let me know what other information I can provide you with.

Ubuntu :: Comp Fans Stay On Low And Comp Too Hot

May 25, 2010

I have noticed a really bad problem on here that i never had on windows 7 even with overclocking.

It seems the fans stay on and are basically idling or are at minimum speed and the computer and graphics cores are just idling at 99c which is really dangerous, but not critical yet since this is an alienware laptop and the technician did say its temperature rating is above that.

The problem is I need to get the multiple fans in the case to start up and cranking like they do to keep the system really cool in windows 7. I kinda wanna get this fixed ASAP as i dont want to constantly be running at this temperature.

Ubuntu :: Disable The GDM/X Power Saving?

Aug 24, 2010

I recently installed the first non-virtual Ubuntu server in our office (to put it in perspective, it's outnumbered several to one by Windows servers). It had an inexplicable array failure, and now it's been retasked to run VMware Server for testing purposes since we don't trust it at the moment. For the sake of ease of use, on this server I decided to install Xubuntu desktop x64, rather than Ubuntu server as I've done with a couple others.

This server is on an old school 8-port Linksys PS/2 KVM. It's got a CRT monitor in the middle of a rack of somewhat aging equipment. The problem I'm having is somewhere between the KVM, this old monitor, and some power saving... when Xubuntu tries to put the monitor in standby, instead it gets this vertically scrolling garbage. The Windows servers in this rack don't have any problem putting it to sleep, but I figured I might as well just turn off DPMS on this particular server.

So I logged in via SSH, stopped GDM, generated a /etc/X11/xorg.conf, and changed Option "DPMS" to Option "NoDPMS" which according to the manpage should take care of it. I also changed the GDM video mode with this xorg.conf so it's definitely being used. Following some other suggestions I found in my search, I issued "xset s off" and "xset -dpms" but this hasn't disabled monitor power saving either. I've been restarting GDM each time I change something. 5-10 minutes later it's scrolling garbage again. What's it going to take to turn off monitor power saving at the GDM logon screen?

Ubuntu Servers :: 10.04 LTS - CPU (Power Saving) For Home NAS

May 18, 2011

I am planning to make a home made NAS running ubuntu server 10.04 LTS. Nothing fancy, simple samba with open access for all and openssh for admin access over the network. The NAS will not have heavy traffic, two home computers with occasional access, just to serve as central location. I am in doubt which CPU to use and I am after both budget and power saving solution.

1. I have an old Athlon Clawhammer I can use but the TDP of 90W is putting me off. I can also use existing 2x512MB DDR-400 memory with it. The board would be new.
2. I would rather invest in new mini-ITX board with built-in dual-core Atom D525 (TDP 13W), VGA and Gb ethernet. I would add 2GB DDR3-1333 memory.

Since I would need a new board for the Clawhammer too (current one doesn't have SATA), I am more attracted to option 2. Would the dual-core Atom be enough running this simple home NAS? I think it should but my experience with ubuntu server is limited.

Ubuntu :: How To Disable The Default X Power Saving Features

Apr 2, 2010

I am using Xubuntu 9.10 on a nettop as a X11 terminal.In order to do that, I created a custom session script that runs some commands instead of starting xfce4-session and the likes from GDM. When I boot this nettop, GDM automatically logs a dummy user in (called "test"), and runs a script that does "xhost +", and opens a small X Terminal to keep the X session alive, while some other computer sets the DISPLAY environment variable to point to <nettop>:0 and runs gnome-session.

My trouble is that after 10 minutes of idle, the screen is blanked(power saving I presume).
I tried to add "xset -dpms" and "setterm -blank 0 -powersave off" to my startup script, in vain. I want my power saving options to be configured on the remote computer, not the nettop. How could I prevent X/GDM/Whoever from blanking the screen ?

Ubuntu :: How To Avoid Power Saving Mode Running 9.04

Feb 19, 2010

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.

OpenSUSE :: 11.2 - Cannot Find Power Saving Features

Apr 18, 2010

I am running openSUSE 11.2 x86_64. I am processing work units from Folding@home on this pc. Strange thing is, when I actually leave the pc alone and working on folding@home, my performance actually drops instead of going up as I would expect. I believe there is some kind of powersaving feature I cant find or something else that's hurting quite a bit on the PC. I am talking about maybe 20-30% performance loss. PC in question is: Athlon II 630.

Already deactivated Cool'n'Quiet from the BIOS. Got no fresh ideas on what could cause this weird behaviour.

Update:
Code:
[22:05:52] Completed 260000 out of 500000 steps (52%)
[22:18:28] Completed 265000 out of 500000 steps (53%)
[22:30:41] Completed 270000 out of 500000 steps (54%)
[22:40:20] Completed 275000 out of 500000 steps (55%)
[22:48:16] Completed 280000 out of 500000 steps (56%)

PC was "idle" working on folding and I came back at 54%, see the huge difference? Frames were taking about 13 minutes each when "idle". When I am using the computer, frames are done within 8 minutes.

Ubuntu Multimedia :: No Display - Monitor Go Into Power Saving Mode

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.

Debian Hardware :: Monitor Can't Go Into Power Saving Mode

Dec 27, 2015

I've recently changed to Debian from Windows, it's a really great adventure so far, but I have one problem. So as I see you can set your monitor into "Blank Page" after 10 or any minutes to save power, like in Windows. 10 minutes passes, without any movement my monitor's led turns into orange and the monitor turns off, that's great, that's what i want.

But after a few seconds the led turns green (like when it's on), and it brings up a little box : "Power Saving Mode" (just like it did after 10 minutes), and it turns off, and then stars again from the beginning . And this goes on repeatedly until a move my mouse to get back from "Blank page" state. (It's like the monitor tries going into power saving mode, but it gets always a little bit of power, to show that text box, and start all over.) So what can I do? I use debian 8.0 "jessie", and my monitor is a LG L1750S(with Nvidia GeForce 9600 GT).

Software :: Disk Caching Utility For Power Saving ?

Nov 28, 2010

I run Ubuntu Netbook 10.04 on my EeePC 1005HA. I'm going to get a SSD for it eventually, but I can't afford one right now so it's running from a 200GB hard disk I scavenged off a dead laptop.

I went in power management and set the option that says "spin down hard drives whenever possible", but this accomplished a whole lot of nothing - whenever the computer is on, the drive's spinning. I ran hdparm -y and the drive clicked off, and then promptly spun back up after a few seconds. Iotop shows occasional tiny bursts of activity from "jdb2/sda1-8", which I don't really know how to interpret, but I don't have anything weird installed so I'm assuming this is normal system operation.

Now, what I need is some sort of application, utility, command - anything - that forces the computer to keep all filesystem changes in RAM with the drive shut down; every five/ten minutes or so (this would hopefully be configurable) it spins up the drive, dumps the filesystem changes to it, and spins it down again.

I realize this presents data loss risks related to crashing and poweroffs when the cache hasn't been dumped to disk, but I'm willing to risk it as Linux never really crashes at all, and since it's a netbook power failures won't cause unexpected shutdowns.

Ubuntu :: Power Saving Mode (monitor Off) Complete System Freeze?

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).

Hardware :: Wost Netbook Ever - Engage Any Power Saving Fetures?

Mar 10, 2011

I've covered a little of the exploration of this in another thread here. Unfortunately no replies.I've now installed as many power-saving features as I can get to work including laptop-mode scripts and my Asus Eee PC 900 has the battery lifespan of a gnat (2 hours 39 mins of extremely light usage including a long period of inactivity although with wireless turned on, from fully charged to battery cutting out, annoyingly this time ignoring my script that registers a critical battery APCI event and shut it down safely).

So, basically is my new Asus Eee PC 900 the worst designed netbook ever, or is linux just not supporting it's power-saving features? It is actually the version that comes with Asus's own linux distribution on it, but I've installed Arch.

[Code]...

What then are the power-saving options left available to me? How can I extend my battery life to long enough to check an email? What out of what I've said ins't working that really should?

General :: Optimizing Laptop Battery Life (Saving Power Consumption)

Apr 20, 2010

So I've come across several tips to optimize battery life on Linux. [URLs]. In addition to undervolting, I would like to underclock. Is there a way to control CPU speed outside of the BIOS via some software control in Linux... or some sort of boot manager? I would like to boot to linux using underclocked speeds and have Windows running full blast. Is there a way to run Linux completely in RAM? I have read that saves on power consumption from the hard drive.

Is there a way of increasing the TX power and if not then why not?

Ubuntu Networking :: 11.04 - Slow Wireless When On Battery Power

Sep 1, 2011

I am running Ubuntu 11.04 32Bit on an ASUS Eee PC 1015PX. I have found a strange anomaly concerning wireless connection when running on battery power. I have been experiencing very slow performance when connecting to my home NAS and also the internet through a wireless connection when using my netbooks internal wireless card (Broadcom Corporation BCM4313 802.11b/g/n (rev 01)) when running on battery power. The card works fine and connects at full speed when running on mains power but as soon as I switch to battery power the card connects to the internet/network fine but the connection speed is very slow indeed. I am using the Broadcom 802.11 Linux STA propriety wireless driver.

Ubuntu Networking :: Wireless Connection Lost When Using Battery Power?

Dec 18, 2010

I'm running Ubuntu 10.10 netbook edition on a Dell Mini 9 - worked around a few wireless issues on setup and connectivity has been fine, but now I'm suddenly losing wifi when I unplug my AC adapter. It still shows me as connected, but when I try to view web pages in Chromium, it will load pages for a few seconds, and then suddenly cuts out - though it still looks like it's trying to load the page.

It's the same if I boot on battery power - it will keep trying to connect to wifi but won't until I plug in the adapter. I'm assuming this probably has something to do with my power management preferences in battery mode, but I'm still pretty new to Ubuntu, and I'm not sure how to fix this. I've played with the options in power management, but I have a feeling there has to be more. Can anyone help me? This has been really frustrating.

Ubuntu Networking :: Slow Wireless Connection When On Battery Power

Mar 21, 2011

I have a problem with my wireless where when running the laptop from the battery the connection is very slow. When the laptop is connected to the power supply everything is fine, but the moment it's disconnected and run on the battery the speed drops when browsing the Internet or accessing files on other computers on my network.

The laptop is a Samsung SF310
Wireless chipset is BCM4313

Code:
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g LP-PHY (rev 01)
Subsystem: Wistron NeWeb Corp. Device 051a
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at f4c00000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: wl
Kernel modules: wl

In attempt to fix this I installed the latest drivers from the Broadcom site using this guide. When I enabled these drivers everything worked well. I did speed test and got the same speeds I get when connected via Ethernet:

Ping 51ms
DL 4.31
UL 0.65

So I set the drivers to load at boot using this forum post as a guide as the steps in the Broadcom guide didn't work and rebooted the laptop on battery power. The wireless connected fine, but the slow speed problem had returned. Running a speed test got the following results

Ping 235
DL 0.54
UL 0.30

So I ran iwconfig when running from battery and then from power supply.
Code:
xxxx@xxxx ~ $ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
eth1 IEEE 802.11 Access Point: Not-Associated
Link Quality:5 Signal level:215 Noise level:160
Rx invalid nwid:0 invalid crypt:0 invalid misc:0
As can be seen the signal quality is 5 and signal level 215

Code:
xxxx@xxxx ~ $ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
eth1 IEEE 802.11 Access Point: Not-Associated
Link Quality:5 Signal level:214 Noise level:164
Rx invalid nwid:0 invalid crypt:0 invalid misc:0

And when connected via the power supply the signal level is 5 and signal level 214. There may be some kind of power saving issue, although there are no relevant setting in the BIOS and I can't see anything in the various wireless control pannels. I have other wireless drivers and there are no problem with those.

Ubuntu Networking :: Wireless Auto Reconnect After Power Savings Mode?

Aug 17, 2011

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.
