General :: Change System Console Screen Blanking Behavior?
Jun 14, 2010
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 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.
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 have tried this with many different configurations, however, I believe that the scroll bar that shows the progress of the boot is preventing it from changing successfully. I don't know how to switch it off. X is not installed. No gui, only tui.
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 ?
Is there a way to imitate OS X behavior of opening applications in Linux?
For example: Assume that I already have Firefox open. In OS X it is very easy to open that window from console (it is the default, using open -a firefox).
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.
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.
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.
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.
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.
I recently installed a new ubuntu system (10.10) as media center. I am running Gnome and xbmc on it. Until here, everything perfect!
I bought one of those cheapass media center keyboards with multimediakeys. Except for one, they all work out of the box.
My problem: When i press the volume down key, gnome lowers the volume of my mediacenter. This might be good for most users, but i have a surround receiver/amplifier (Denon AVR3310) that should handle the sound.
In fact, i am looking for this: When i press the volume up/down key, instead of changing the volume of my mediacenter, gnome should execute a script i wrote. This script sends commands to my receiver (using the serial port or the network connection) to lower/raise the volume.
Small additional question: I would like to get the one button that doesn't work yet to work. I have a 'mc' (mediacenter) button on my keyboard. I would like to make this launch xbmc. When running 'xev', i don't see any output when i press the button.
Is there any way to specify which monitor the console is displayed on in Linux?
Details: I have a 3 monitor setup with 2 video cards. When I boot the computer, the BIOS displays on the PCI graphics card (which has a small monitor). When starting Linux, the console is displayed on the same monitor. Is there a way to have the console output on a different monitor? I'm using the vesafb framebuffer.
I don't see a way in my BIOS to change the default video card.
I upgraded to Fedora 12 a few days ago and it seems that my X session is timing out after an idle period. Where can I change the settings or disable this behavior which was not happening on Fedora 11?
I'm using 11.3 64 KDE upgraded from 11.2. Every time I hit the shift key, the mute toggles. I've already tried changing the settings for kmix under global key shortcuts. Any ideas on how I stop or change this behavior?
I've been running Ubuntu 10.10 for four days now and love it. Is there a way to change the default behavior of the power/logoff icon on the taskbar?(not on Ubuntu now and forget what the bar is called) Instead of asking me what I want to do (power down,restart, log off, etc) I would like it to power down the PC.
I have been running two Ubuntu 10.10 servers for some time now. My main server is 10.111.1.65 and backup server is 10.111.66. The main server is to host my website and ssh remote access (Key auth). The backup server pulls via ssh key auth what is in my /var/www (among other folders) to the backup home dir (encrypted). For some reason today I checked the uptime and it was 7 hours on both servers. All my other computers on the same power supply have a uptime of over a month. For some reason I now cant access backup via ssh from main's key (I could before) and I can not get to the home dir, see below:
Code: carlos@UbuntuSvrDell2400:~$ sh "Access-Your-Private-Data.desktop" Access-Your-Private-Data.desktop: 1: [Desktop: not found
I just tried uprgading from 10.10 on my daughter's pc to 11.04(beta) as we wanted to find out about Unity et al. I thought the upgrade went well but on reboot when the desktop comes up, it's all funky in behavior - mouse is jump, arrows don't reliably work the menus - odd background images show up in graphic blocks. Do you think I can salvage this, or should I am I stuck reloading back to 10.10?
Just loaded Lenny, mostly with defaults. I'd like to go back to a command-line login for the console attached to the machine. Of course, I'd like to be able to 'startx' whenever I do want the GUI up.
