General :: Monitor Power And Lock Screen - Ubuntu Lucid

Oct 7, 2010

I'm trying to get my screen to turn off whenever I lock my screen. I know that in Power Management, there's an option to turn off the screen after a set amount of time, and I know about xset dpms force off, but the former doesn't allow me to turn off the screen from the logout menu, and the latter only turns the screen off for a short amount of time (1 minute or so. The screen just turns back on by itself).

Is there a script I can modify to change what happens when "Lock screen" from the logout menu is selected, or is there a script I can add to the panel to lock the screen and then turn the monitor off (and turning it back on when I shake the mouse or something)?

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

Feb 4, 2010

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.

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

Nov 21, 2010

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).

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).

Fedora Hardware :: Monitor Not Going Into Power Save Mode

Jan 26, 2009

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.

Fedora :: Power Management Doesn't Turn Off Monitor

Jun 15, 2009

I just upgraded from FC10 to FC11 (32-bit) on an old Dell laptop. I set my power management settings (in Gnome) to turn the monitor off after some idle period but always leave the computer running and the hard drives powered. I also set my screen saver to a blank screen. I noticed that the screen saver does come on (turning the screen black), but the monitor back lighting never goes off. I tried different idle times for the power management settings (I usually set it to 1 min, but some other posts implied that 11 mins might work). I should also mention that this is after I've logged into a user account, not sitting at the login screen.

I didn't have this problem in FC10 (the monitor would actually turn off) so I figured it was a bug in FC11, but I can't seem to find a thread addressing this issue. I've found some what similar threads, but none mentioning this particular problem.

Fedora :: 14 - Overriding Power Management Preferences - Settings Are Set To Never Put The Monitor To Sleep

Nov 17, 2010

I have an odd problem since preupgrading from Fedora 12 to Fedora 14.

My power management settings are set to never put the monitor to sleep, yet after a certain amount of time, lo and behold, the Fedora box has gone blank and I have to enter my user information and password to get back to my gnome session.

In the power management preferences I have "never" selected for both putting the computer or display to sleep.

In the screensaver preferences "Lock Screen After" is *not* checked. (And if I click "advanced" I also note that "Power Management Enabled" is also *not* checked).

I'd just as soon not have to "log on" to this machine every time I'm away from it for a while.

General :: Execute A Command When Power Source Changes

May 20, 2010

My laptop has a dead battery. Even when it's fully charged, if the power cable is pulled out it only lasts for about 4 minutes before it dies. I'm running Ubuntu Lucid Lynx 32-Bit. What I want to do is create some sort of script or program that will immediately set my computer to go into hibernation once it detects that the power cable has gone dead. I'm willing to look into all ways of doing this. I can program in C, but I'm not familiar with the API used to manage Power Management in Linux.

CentOS 5 Hardware :: Kernel-xen 64bit And Ati ES1000 - Monitor Goes Blank And Says "no Video - Going To Power Save"

Nov 21, 2010

I have problem with onboard ATI ES1000. Server details:

Supermicro X7SBI, Q6600, 8G ram. Centos 5.5 minimal installation, without X.

Problem is that with all kernel-xen x86_64 from current kernel-xen-2.6.18-194.26.1.el5.x86_64 back to kernel-xen-2.6.18-128.el5.x86_64 after kernel boots monitor goes blank and says "no video, going to power save".

Google finds similar problems and sugestions was to add "nomodeset". With this option monitor also blanks after kernel boot, but says "out of range". Other options to modify xorg.conf does not apply, becouse there is no X installed.

I try with multiple monitors, without success. This happens only with 64bit kernel-xen. All other 32 and 64 bit kernels and 32bit kernel-xen works fine, video is ok. This happens to 6 servers, all are same hardware, used as cluster. Installation with "linix text" allways is fine, video disappears after first reboot when standart kernel is booted. I also tryed with almost all possible "vga=xxxx" kernel options and none of them works.

What else to try?

Ubuntu :: Shell - Command-dependent <tab> Autocomplete?

Jul 6, 2010

I was using windows recently and noticed that in their command line, the autocomplete is in some ways a little more intelligent (although based on my short experience ours is more robust); for example, if you have a directory named blah and a file name bl, in Linux "cd bl <tab>" will result in "cd bl" while in Windows I get "cd blah" because it recognizes that blah and not bl is the appropriate argument to cd. Similarly unrar will target rar files first.I am not saying Windows command line is better; Windows command line is in general a piece of junk.

Ubuntu :: Test Command In Shell Script?

Aug 29, 2010

I was trying to write a script, but for some reason I can't test two variables using -gt:

a=`expr $currentSize + 0`
b=`expr $fileSize + 0`
[$a -gt $b]
this is what I get:
[22234534: not found

what is the problem? It seems like I can't check if a variable is greater than another but only if a variable is greater than a fixed number. Is that so? By the way the variables $fileSize and $currentSize exist and $a and $b have a value.

Ubuntu Servers :: Run A Shell Command As Another User?

Apr 26, 2011

The short version: I have to manage some virtual machines using php shell_exec function, so far I cant do this because apache is run by the user www-data and virtualbox by the user vboxuserFrom what I've read so far, I've thought of 3 possible solutions: 1.- Create a script on my vboxuser that I can call from php to manage the Virtual Machines.2.- Change the apache user from www-data to vboxuser so I can manage the Virtual Machines through php
3.- Reinstall VirtualBox, this time using www-data as my user. I'm not sure if any of these will work and I'm not too sure of which would be the best solutionNow the longer more detailed version:

I have a remote server running Ubuntu 10.04.2, in that server I have set up VirtualBox so I can run several instances of WinXP to perform different tasks. Everything is setup and I can manage the virtual machines through SSH. If I want to run them as a different user than the one that created them (a user that so far only has been used to create the Virtual Machines) I have to do sudo -u vboxuser.Now, I need to create a PHP script to manage these virtual machines (I know about phpVirtualBox, but it's not what I need). If I try to run the virtual machines using shell_exec() from php, I get no answer at all (And I have tested that shell_exec is working on my server).

Ubuntu :: Emacs -- Run Shell Command W/o Output?

Jul 12, 2011

I write LaTeX in Emacs and then run a shell script to process the LaTeX code. I used to run a subshell buffer with M-x shell and then execute the script from within there, but this results in a lot of switching between buffers, which seems unnecessary. Then, I found out about executing shell commands with M-! cmd RET, as described here:[URL]The problem with this is that the output from the script splits my screen. It's a nuisance, and I would like to run the script without any output. I've tried appending > /dev/null to the command, but it doesn't work.For example, when from within Emacs I enter M-! followed by

sh make.sh > /dev/null
it splits my screen so that one portion displays output from the make.sh script. I want it to run silently, and leave my Emacs buffers alone
