Ubuntu :: Screen Blanking Out After Ten Minutes / When Output To TV Over S-Video
Apr 7, 2011
I'm running Ubuntu 10.10 w/ an ATI HD 4350 and trying to output to a CRT television over S-Video @ 640x480. Problem is the screen blanks out after ten minutes no matter how I configure my screensaver or power management settings. I've done some research regarding commands in Terminal, but I can't find anything straightforward.
I have both Computer and Display set to NEVER SLEEP in power management. yet after about five minutes of inactivity, Ubuntu always blanks out the screen (i.e., just a black monitor screen but the monitor power light is still on).How do I stop this? I want to continue to see what is on my desktop--I do not want the screen to blank out ever.
I'm using Debian Lenny with an nVidia 8400GS. Before I changed motherboards (and graphic cards, as apparently AGP doesn't exist anymore) this set-up worked fine, but with the new hardware, I can't use the TV as a second screen anymore: there's simply no image going through. All that's visible on the screen is "No video signal".I've tried the proprietary nVidia driver and nvidia-settings, but nvidia-settings doesn't even see the second screen. I've tried adding it manually to xorg.conf, but again, nothing.
I have disabled power management and un-installed gnome-screen-saver and themes. But the screen keeps going black, and it don't go into power-save. Exactly as if the screen-saver was present. Can it be xdg-utils ?
10.04 32bit Desktop edition. I have unchecked the "Enable screensaver when the computer is idle" option and have set "put display to sleep when inactive for" to "Never" but the display is still blanking out!
I have removed gnome-screensaver, and to the best of my knowledge, it has not been replaced it with any other screensaver application.I have set System->Preferences->Power Management to never blank the screen. However, Ubuntu still blanks the screen if there has been no user interaction for a while.
I recently upgraded my 10.04 installation to 10.10 and ever since my dual monitor set-up has been behaving oddly - my secondary monitor randomly goes black for a second and then comes back as normal. I've tried to reproduce it with no luck and it isn't something I experienced with previous installations so wondered whether it's a known problem with 10.10? NVidia Quadro NVS 290
The X server in Debian seems to have a "funny" habit to suddenly start blanking the screen if I don't touch the mouse or the keyboard for a while, although I've used the xset command (xset -dpms s off) in my ~/.xinitrc to tell Xorg specifically NOT to blank the screen. I know how to disable screen blanking in /etc/X11/xorg.conf, but I'd rather not have the xorg.conf file at all.
So, I'd be interested to hear your suggestions about how to disable the Xorg screen blanking without using the xset command or the xorg.conf file. Is there some other file in /etc/X11/ that I could tweak to disable this highly annoying desire of Xorg to insist on blanking my screen after a bit of idle time?
How do I stop the display from turning off? In 'System Settings/Screen', I can only choose from a preset range of minutes - there is no option to disable it. Very annoying when watching a 90 minute movie, for instance. At least under FC14 I had the disable option. I tried unchecking Power Manager in gnome-session-properties, but that disabled the system from suspending when the laptop lid is closed and might have other ramifications as well. I tried disabling Screensaver in gnome-session-properties, but 'System Settings/Screen' still showed up with the same options, so it appears to be unrelated. Anyway, I suspect this is a power management issue, not a screensaver issue.
Aboard TinyCore 2.7 and opting to run without Xorg. I'm needing either a pointer or syntax example. Seems my monitor supports dpms after executing a quick one-two with:
$ xset s blank $ xset s 150
Yet I'm unsure how it would look placed in Tinys .xsession:
I recently installed Mint 9 using/trying KDE, which I found very intuitive and feature-rich. However, a snag soon appeared. The screen started to blank every few seconds or minute. This is pretty annoying. I have so far tried every tried-and-tested means available, exhaustively, to no avail. Even their website has this as a known issue, yet the solution (i.e. configuring the screen resolution) doesn't seem to work for me.
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've just installed 12 new Dell Optiplex 960 computers with Dell 2009W monitors. They are identical hardware and OS installs. Some of them are exhibiting a weird problem with their screens: They boot up and run just fine, but then the monitor goes black for 2 or 3 seconds, and comes back, with the small DVI icon popping up in the upper left corner to show which video connection is active. This repeats at random intervals continously; sometimes just a few seconds between, and sometimes many minutes.
The problem initially happened on just one machine so I had Dell swap the motherboard thinking it was a hardware issue. That did not fix it. Soon after that, I got reports from several users of the same problem on other of the new machines.
I've done a very basic install of CentOS 5.5, skipping all of my local configuration management stuff, and it still happens. Then I installed Ubuntu 10.04 and over the last few hours the machine has been rock solid. No video issues at all.
I'm trying to prevent GDM/Gnome from turning the screen off prior to login. It's current behavior, under 3.14, slowly fades the screen out and then enters DPMS mode after 10 minutes.I have zeroed out the following dconf settings, under both root and user, but the default behavior persists.
How do I change the screen blanking behavior on Linux virtual terminals?
For example, if I switch to a VT from X, login, and leave the system alone for 5 minutes or so, the screen will blank like a screensaver. It comes back with any keypress, like a screensaver.
Mostly I just want to change the timeout, but I'm also interested in other settings.
If it helps, one of my systems is running Ubuntu 10.04 with the stock graphics drivers. fbset shows the console using the radeondrmfb framebuffer device.
Linux and ubuntu. second my computer is single os with ubuntu 9.10. the problem i have is trying to watch any thing streaming media. Movies, music, like from ....., divx, or even megavideo which seems to work best right now.
What happens is that the video or firefox it self seems to freeze up every 10 minutes or so.
It may be that i need to increase the buffer memory size but i do not know how to.
I have updated my computer and firefox and installed and updated any possible add-ons that would fix the problem.
What im asking for is either a patch or add-on that will help this problem or how to run windows inside of ubuntu. (Im am tired of windows and ubunu has made my computer work so much faster, when i am sure that i know how to make this computer stable with what i need for internet use i will apply it to my other computer.)
For some reason my computer screen keeps getting completely dim after around 10 minutes of inactivity. It's been happening when I use Oracle VM Virtualbox to watch movies on Netflix.I have all the setting on my computer so it doesn't dim the screen at all, so I don't know what to do now. You can see my settings on the attached images.
Since upgrading to 11.04, my screen goes blank if I am not active for 10 mins. This is really annoying if I'm sat on the sofa watching a movie through the computer!
The screensaver is set to 1 hour and the power management settings are set to 'never'. I never had this problem with the previous Ubuntu version. I'm on a desktop rather than a laptop.

I'm using Lucid and after a few minutes of inactivity the system goes into the Lock Screen status also available under the shut down icon. now I don't like the screen to be blocked mainly cause when I get back I've to type again my password everytime. Under Karmic the screen used to go into a sleep status but it only needed a touch of the mouse in order to come back....
I am trying to install ubuntu 10.04 on notebook, after choosing install, ubuntu starts after about 10 minutes with log screen, but I don't know logging parameters. Also the same with ubuntu 9.10. Hardware problem?
I have clean installed Ubuntu 10.04. After every 10 min. or so of not moving the mouse, I am asked for my password. How can I extend those short min. to say an hour?? Also, at startup I do not have a splash screen only a black screen for about 1min or so. How can I watch the splash screen at startup?
I have been having an issue with my screen blanking out after a few minutes (number of minutes unknown), since I reinstalled Fedora 12 (KDE) a couple of weeks ago. I have tried, yes, a lot of things to try to set it so that it doesn't blank out, to no avail. I have spent a lot of time on the Fedora forum seeking resolution, with a variety of suggestions, all to no avail. I went into System Settings > Power Control, and fooled with things around there and they didn't work. I tried xset and dpms and shutting them off. Still no cigar.
I have actually done a bit of searching on this, but the suggested solutions either don't work or are not applicable to my setup.First, I changed the setterm link in /etc/rc.d/rc.M to be setterm -blank 0 -powersave off -powerdown 0and have xset s off in my fluxbox startup file.Nevertheless, the screen goes blank after 10 minutes. I can't figure out what is causing it and how to stop it.
Just got my EeePC installed with the latest release of ubuntu netbook and have used update manager to get the system to the latest versions including the latest Adobe flash player.
I'm having problems with BBC iPlayer though. When I watch in full screen mode, it only lasts for 10 minutes then reverts back to the Firefox browser.
I have a Dell Vostro 200. Have been running Ubuntu on it for 18 months - no probs. Recently it became very slow to boot. 5-10 minutes before Ubuntu startup screen appears. Have installed Ubuntu 10.10 (on a reformatted hard drive) today. No change. It's fairly certain to be a hardware problem but I don't know where to start.
