Fedora :: Make The Display To Turn Off When The System Enters In Save Energy Mode?
Sep 4, 2010
I installed fedora 13 in its LXDE flavor in my laptop. I noticed when it goes to save energy mode, the TFT retro-illumination is not turned off. The display just stays black with light. How to make the display to turn off when the system enters in save energy mode?
How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup.
The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen). But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor?
After installing Ubuntu 10.10 on a laptop Acer Aspire 5942G graphics card ATI Mobility Radeon HD 5650, some time after the boot falls color monitor. Color depth is only 65000 colors or more. In all settings, all is well (and the color depth is there spelled 24bit). Color depth is reduced at some time after a reboot. After further experiments with the screensaver was set: color spoils the energy saving mode and turn off the display!After disabling the option "disable display through .." color is now always saved in the norm!
I am running a dedicated server with linux cent os 5.5 32 bit with lighttpd, php 5.2.14 and mysql
I am getting problem in my server. The filesystem enters read only mode automatically and then I can't edit any file in my server. This happens by itself. I tried to run fsck command and it gives the following output:
When I try to run the 'system-config-display' program for Fedora 11 and I use the dual head tab, attempting to save the settings results in this:

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? NMI received for unknown reason 39 on CPU 0. Dazed and confused, but trying to continue Do you have a strange power saving mode enabled? I read something about it being the video card, so I took my old one out which it being an ati, an replaced it with an nvidia.
Is there a command to turn off my Broadcom wireless card to save power. In Apple, the have an Airport off listing under the airport menu, Is there something for Fedora?
I am currently trying to turn off ordered data mode for ext3 filesystem. I want to shred some files and apparently this won't work with journaling on.
I can't seem to find any good explanations of what exactly "ordered data" means in terms of data recovery/security...or at least none that are written in simple n00b terms. It is all written in terms of disk crashes and whether old data will mix in with the new. It doesn't say whether one's cousin will be able to poke around and find some thought-it-was-deleted porno if he's on the computer.
Can someone step me through the process of turning this off using tune2fs? (if that is the best way to do it!) Do I have to revert to ext2? Can I turn it back on later? Will I lose data (for example, does the drive need to be reformated?) once this change is made? And how does one find, read, and delete/shred the journal itself? Is "ordered data" even a real problem for data recovery?
It appears my profiles are gone, and thus i have got no way in changing settings in the 'Desktop Configuration' (Systems Settings)so, when I go toapp starter --> Configure Desktop --> Power Mgmtthere are NO profiles under 'global settings' or 'power profiles'anyone has got an idea what's cooking here
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.
I recently installed Fedora 13 64 bit with KDE and everything works perfectly with the exception of display properties. I have two monitors which I have setup as multiple displays here is the result of xrandr when all is good.

I'm have an ATI Radeon 3450 HD graphics card and I believe I installed the mesa driver as the proprietary one simply won't install.
I have just installed KDE 4.4 on Fedora 12 in addition to GNOME. The default Display resolution is the highest available. I changed it to a lower resolution. However, when I reboot, the resolution switches back to the default setting.
I have XFX ATI-HD5670 and use proprietary catalyst 11.2-1 in 64-bit Fedora 14.
I am not sure when this started, or if it ever did work before, but when I started noticing that the screensaver will not turn off the monitor, I set the gnome power manager to make the monitor sleep after an hour.
Now, the display will not turn back on after it has been in sleep mode. I know the system is still running fine as I can ssh from another PC and see that everything seems to be normal, no error message in dmesg, /var/log/Xorg.0.log, etc.
/var/log/Xorg.0.log shows that monitor DPMS is not detected but still enables DPMS:
Is this a problem with catalyst driver? I know it's not the PC or the monitor, because I have a 2nd PC with the same video driver with the same problem, but others without this driver don't (ati open source, nvidia, etc. all work fine.)
I'm wondering if the problem always existed before, but I just didn't notice it because the display sleep mode was never set? If that's the case, my hunch is that it looked like it worked because the monitor was smart enough to turn itself off when the screensaver kicked in and just showed a blank screen, and the video driver was never involved with sleep mode until I set it in gnome power manager, at which point it started showing this problem of not waking up? And because the screensaver was no longer set to blank the screen, but to show some animation, that's why the monitor will never sleep anymore?
my mediacenter is attached to an beamer with the optimal resolution of 1280*720 ubuntu 10.04 doesnt offer me this revolution (on my intel 915 graphis controller). this means i have to add this resolution to the possible resolutions. first i used cvt
now i can select and use the new resolution - until next reboot. after an reboot 1280x720 is again not available. even if i work with sudo - the resolution isnt there....
I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?
F9 has been running great since it came out. I read that one should install F10 before F11 so I did install F10! Everything went great.
(1) Then I tried to install the F11 iso dvd. After the "anaconda started" message at the bottom of a blue screen, the screen went blank and occasionally the message would appear: "cannot display this mode 2:dvi-d". Thinking the monitor had gone into power save, I hit many keys and moved the mouse to no avail.
I gave up! BTW I had checked all media CDs for errors.
(2) then working under F10, a little message appeared from the lower right of the screen asking if I wanted to upgrade to F11.
I accepted and again "cannot display this mode 2:dvi-d" on a black screen after anaconda started on a blue screen. This time no ISO DVD F11. I've never seen such an error message in 11 years (off and on) of using Linux. HD Disk activity was showing on the disk activity light so I let it run all night and part of today. I hit a bunch of keys and moved the mouse and the blue screen returned saying all was done and restarting.
After restart, I seem to have F11 installed. I did a yum update and got some more F11 updates. On the grub screen, the only F11 kernel was the PAE kernel which I selected and got:
Does F11 have any F11 kernels? BTW running >setup (hd0,0) under F10 grub ruined my XP prof OS on scsi 0 so I reloaded XP Prof from scratch.
Questions:
(1) what is this "cannot display this mode 2:dvi-d"?
(2) Now I cannot boot to Fedora 11 and all the advice on how to reinstall grub has failed failed. Did a rescue and chroot /mnt/sysimage and the fdisk -l
Now XP Prof seems to be on /dev/sdc and Fedora on /dev/sdd. What do I do? In the meantime I have retreated to Fedora 10.
during boot-up on my desktop, running openSUSE 11.4 with KDE 4.6.3, there are sometimes (not always) some failed services. Most of the time it is postfix and some other service. Today it is just mcelog. So when I switch to the first terminal by strg+alt+F1, I see that mcelog has failed.The system is running anyway, so I wonder if it is safe to turn them off? I would turn off postfix and mcelog. Do I harm the system with that? Would it boot again, after I have turned them off? Or is it recommended to let them stay as they are?As far as I understood, postfix is just a mailserver, which would be used, if I would run a mailserver on my own. But I donīt. I just read mails, via IMAP... But mcelog? Whats that?
how do I make grub boot to allow me to choose, like safe mode and normal mode and all that second, how do I do automated back ups (preferably using file copy) for something like every sunday at 11:00 am using the command line, i use to know but forgot.
In fedora, to use browse mode, you have to right click on a folder and choose browse. How can I make that the default option, like in Ubuntu if that rings a bell on what I am talking about. Every time I double click a folder I would like browse mode.
Disclaimer: I have very little linux desktop experience...I've only used command line stuff for work in my previous life. I am joyfully coming off of a long addiction to MS but am having a bit of a hard time adjusting.
ISSUE: I can't seem to figure out how to turn off suspend mode. I have turned every setting I could find in the power management to "do nothing" and I have turned off all of my power mgmt options in the system bios. A "friend" suggested I remove HAL...which caused me to lose my secondary internal HD and all of my usb devices...and the issue persisted. Every 20 minutes of no action the screen blanks and my monitor goes into standby mode which is making watching movies in bed a less than relaxing experience.
Some background that may or may not be useful: I installed kubunutu 10.04 (2.6.32-28-generic) from cd on a fresh HD. Initially I had issues with the wireless network and alsa/pulse sound. I worked through those through much trial and error but the suspend issue persists. I've uninstalled and re-installed lots of packages I probably shouldn't have been messing with and would really like to avoid a reinstall as this seems to be the final fix I need to get things running the way I want them.
Configure the HTTP server via system-config-httpd brings up some nice gui.I start a console, login to root and start it with: system-config-httpdGoto tab Virtual Hosts, then addI name my Virtual Hosts "sea", set its document root to: /home/sea/webs/sea.hs/www where index.php is located for that 'local test server'.Host information is on Name based Virtual Host.But what do i have to enter for IP Adress and Host Name? Neither of these accept 127.0.0.1 nor localhost Further, when i try to exit, it wont let me close the app.Its not saved, hence i can even delete the default virtual hosts and its there again after restarting the app Even with adding sea /home/sea/webs/sea.hs/www or sea localhost.localdomain localhost to /etc/hosts doesnt change anything
I am running a service (Selenium) that relies on launching browsers, even when there is not an active display. So in my startup script, I have
Code:
What is the equivalent code I should put in the shutdown method? In other words, to de-activate the display? Right now, if I restart, I get the errors ...
Code:
server: Fatal server error: Server is already active for display 15 If this server is no longer running, remove /tmp/.X15-lock and start again.
Based on much internet searching, I've found that I was/am not the only one struggling to get Fedora 10 to span the display across a laptop screen and an external monitor. So what I have here are instructions to do so:
1) Fedora 10 does not (by default) use an xorg.conf file to configure the display. So type the following command into the command line: yum install system-config-display
2) Go to the menu bar and navigate to System>Administration>Display. I left all the display settings as they were and hit OK (repeat this step twice to make an xorg.conf backup). This will generate the xorg.conf and back up files in the directory: /etc/X11/
3) Now we need to see what size virtual screen you need. Type the following command into the command line (without the quotes): "xrandr --output VGA --auto --right-of LVDS" It will tell you that you are asking for a certain size screen. Write those numbers down. I have a 1600x1200 external monitor so my number is 2624x1200 (1600+1024 x 1200).
4) Change directories to /etc/X11 and type (without the quotes): "sudo gedit xorg.conf" Scroll down to where the device section is. Mine looks like this:
Some videocards need to turn 3d acceleration off in order for dual screens to work. It is important that you turn off desktop effects if you turn off 3d acceleration!!! So under the driver line add the line (with quotes): Option "NoAccel" "true" Mine looks like this:
[Code]....
Scroll down to where the screen section is, and then find the display subsection. It should look something like this:
Is there a way for the time at the top of the screen to display seconds as well as the date ?
My clock seems to be about :40 seconds off... before i upgraded from f-13 i had my time controlled by ntp(how to verify ntp is enabled) ? even with network time = yes, it seems to lag a little.
I figured out the network time. it is under a whole separate menu for some reason.
Is there a way to get weather/ temperature like in classic gnome ?
Rite now my clock reads: tue 3:50 pm...Is there a way i can make it read: tue, aug 20, 2011 3:50:45 pm
Can anybody have an idea of an ftp client code using raw ftp commands.
OR Can anybody tell me how to turn off passive mode using raw ftp commands. PASV is the command which turns on passive mode but there is no such alternative of active mode. I have already tried using pasv_enable=NO in vsftpd.conf but that is not working.
The GUI for network configuration of Fedora is marvellous such that the configuration is almost fool-proof. But how can I make the connection by hand in the command line mode? It goes okay except the very last step. When I disconnect the eth0 interface from the right-hand side of the desktop GUI, I tested how to bring it back by command line but I failed. When disconnected, the ifconfig still shows the eth0 interface, with just the ip address portion changed.
I tried "ifconfig eth0 192.168.1.xx" to give it an ip address but the connection is still down even if the ifconfig shows an ip address for the eth0 interface. Then I tried "/etc/init.d/network restart" and "ifup eth0" and also "route add defaut gw 192.168.1.1" but none of these could accomplish the same work as a single click on the GUI to connect. I am very curious about how to do it in the terminal.
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.
