Debian Multimedia :: How To Disable Xorg Screen Blanking
Feb 11, 2011
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?

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.
org.gnome.desktop.session idle-delay
org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout
org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout

I am new to Linux and installed Debian. After the Installation I started Debian and ended in a black screen. I came out there changing to a terminal (ctrl+alt+F1) but I dont know how to get Xorg running. I am using the Mainboard:Gigabyte GA-D510UD without any extras (means just the Mainboard with Ram and an IDE Hdd). here is the Log file from Xorg [URL]... System Information is in the log.

After a install on a old Toshiba today everything looked fine. But when i tried to start Xorg it start but doesn't use my whole screen. It is not a resolution problem it just doesn't use the whole screen. Hopefully this explanation is understandable. On lenny i had the same issue but once i changed the console resolution size in grub everything was fine. Sadly this is not the case with squeeze. I already tried "X -configure" and had a look at the generated xorg.conf (posted below)
[code]....
After that is tried to run the generated xorg.conf but then it just frooze.

I'm using Gnome as my desktop environment in Debian stable, I have previously address this issue at another post with the solution of setting xset command to disable screen blanking. However I'm still looking for a method that can automatically disable screen fade while watching videos in a browser. I don't want to permanently disable the powersaving idle method. I have both cpufreqd and laptop-mode-tools to conserve my powers.

I run a custom build of linux running kernel 2.6.24 and busybox. At the moment I'm investigating a kernel panic. The problem is that after 10 minutes the screen is blanked, i.e. it is still on but has been turned black. If you press a key then the command prompt is shown once again, but if the kernel has crashed then this won't work and any info about the panic is inaccessible. So I'd like to prevent the display being blanked. I've tried booting with 'apm=off' and 'apm=off acpi=on' kernel parameters but neither had any effect.

I've installed Squeeze 2.6.32-5-amd64 on my laptop (Alienware M17X R3, Intel i7 Sandybridge, ATI Technologies Inc Broadway [ATI Mobility Radeon HD 6800 Series])The screen is 17", with maximum resolution of 1920 x 1080. After a default install of the operating system, the maximum resolution I can select is 1280 x 1024.My research so far has suggested that I need to edit the /etc/X11/xorg.conf file and provide xorg with the necessary resolution.
Again, by default, the xorg.conf file is not created. This leads me to believe that xorg is scanning my hardware at startup and providing me with whatever it thinks is appropriate. I tried following these instructions to generate an xorg.conf file. This process created an xorg.conf file under /root/.
When I copy this xorg.conf file to /etc/X11, I get a blank (i.e. black) screen. Deleting this file restores the default resolution 1280 x 1024.This system is dual booting with Windows 7. Under windows I am able to get a 1920 x 1080 resolution, so I know my hardware is up to it.At this stage I have yet to install the drivers for the Radeon graphics card.What are my options regarding configuring xorg to give me a higher screen resolution?

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 ?

Screen blanks out while I'm watching a movie. It happens about 10-15 mintues of not touching anything. As you can imagine, really annoying.

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 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.

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.

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

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.

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:
Code:
Xvesa -br -screen 1024x768x32 -shadow -mouse /dev/input/mice,5 -nolisten tcp -I >/dev/null 2>&1 &
waitforX
"$DESKTOP" 2>/tmp/wm_errors &
export WM_PID=$!
[ -n "$THEME" ] && cp /opt/jwmThemes/"$THEME" .jwmrc-theme
if [ -n "$BACKGROUND" ]; then
setbackground image /opt/backgrounds/"$BACKGROUND"
else
[ -x ./.setbackground ] && ./.setbackground
fi
[ "$ICONS" == "wbar" ] && /usr/bin/wbar.sh
[ -x ./.mouse_config ] && ./.mouse_config &
[ $(which flit) ] && flit &
[ $(which watcher) ] && watcher -g +0-0 &

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.
Here is the output of lspci:

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.

I'm trying to get my screen resolution set in Mythbuntu 9.10, but there is no xorg.conf on my system! I'm trying to figure out what to do (the xfce tool on mythbuntu doesn't offer the correct resolution, and I'm not even sure what driver I'm using). I've seen other threads saying to run nvidia-setup or somesuch. I assume the appropriate tool in my case would be aticonfig (I saw that elsewhere too) as I'm using an ATI Radeon 9600XT, but that tool says:
Code:
aticonfig: No supported adapters detected

I upgraded all xserver-xorg packages in my notebook. After restart system Xorg (GDM) don't run. My screen is black. If I will go to console CTRL+ALT+FX, screen is black too. I will go to console only in single-mode and I tried run dpkg-reconfigure xserver-xorg, but without results. I haven't got /etc/X11/xorg.conf in my system. I have got integrated Intel graphics card.

A few months ago my monitor broke and began using an old one that does not have EDID.Since then i havent been able to configure my computer with a stable video configuration.I`ve tried a thousand times to edit xorg.conf and i actually got it let me use resolutions higher then 800x600, but when i reboot my computer my usuall setting 1024x768 gets switched back to a lower one - its a pain... my icons get scrambled, the gnome panels, etc.Do I need to edit any other file then xorg.conf?
And another thing I noticed today is that the gnome display manager does not recognise the higher resolution of nvidia-settings. Does it have a seperate settings file?

I'm trying to install Xorg manually in Squeeze on my IBM X30 Thinkpad with intel graphics (it works in Lenny). I used aptitude and installed "xorg" and "fluxbox", but when I restart my computer I get a blank screen, instead of the console login request that I was expecting. (Note: I did not install any login managers). So exactly what happens is that the screen goes black (just backlight on)during boot process. Once I'm at the black screen doing CTRL+ALT+Backspac, Ctrl+Alt+Del or Ctrl+Alt+F[1-7] will not result in anything.
I tried booting with the single user mode, but same result, so the only way I could acess my log-files was by using a systemrescue-CD. What I find odd about this is that I cant find any configuration files at all. No xorg.conf anywhere in /etc, /etc/X11, nor in /home. I don't even have a /etc/X11/xorg.conf.d folder.Am I expected to write these by myself? And if Xorg is the source of my troubles, why is it starting by itself, without any installed login managers? Xorg not working is one thing, but not even being able to access the console, or log in to my computer makes it rather difficult to search for errors.

I just recently got a Dell Inspiron 1525 laptop and have installed Debian on it. When I installed it, I did not install the 'Graphical desktop' packages...only the 'Standard system utilities'Everything has been fine, however when I installed Xorg (aptitude install xorg) and restarted my computer, my screen goes blank at bootup. I can see the grub menu, as well as the beginning bootup process, up until udev begins to load. I have a feeling it has something to do with KMS now being loaded but am not sure.

I installed debian 5 in a pc with a Intel 4 series VGA. The optimal resolution for the monitor is 1360x76, but the system does not allow that. I tried to change my xorg.conf, but got no success.In my xorg.conf I used this:
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"

I have an Asus z9100 laptop with an Intel 855GM integrated graphics chip, which is running Karmic (the purpose of the laptop is to be a MythTV frontend so my understanding is that it needs to run 9.x in order to connect to the MythTV 0.22 backend - I have installed and configured this using the installable Mythbuntu package) and the laptop is subject to this bug which causes random freezes:
[URL]
So, following advice for similar freezes I've seen, I have added the following options to my grub menu.lst on the kernel line:
nolapic nomodeset
and I have edited xorg.conf so that it makes use of the vesa driver instead of the Intel driver. This results in no freezes and if I wanted to watch Myth on the laptop screen I'd be squared away. However, the laptop has a damaged screen so the point was always to output the signal to an external monitor via its VGA out.
When I attach the external monitor and boot with the setup as described, the external monitor is never detected. But I noticed that if I remove the "nolapic nomodeset" from the kernel boot line, it is detected. However, signal is only output to it during the earliest part of boot (when the Ubuntu logo is in the center of the screen before the full-screen graphic with the animated progress line), after which the external monitor goes black and all the display output goes to the laptop screen. The external monitor power button is still lit up green as if it has been detected and is receiving signal, but it's just a black screen.
get the signal out to the external monitor after the initial part of the boot process, using the vesa driver? Here is the current state of my xorg.conf:
Code:
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
