Hi,
my laptop's (Thinkpad X201t) screen goes black if I don't use it for some time (between 6 and 15 minutes). In the gnome power management preferences the option "Put display to sleep when inactive for" is set to never - for both "On AC Power" and "On Battery Power".
This also happens if watching a movie using totem.
If an external monitor is connected both screens go black but the external one gets back on after like 3 seconds.
Video card: 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
CPU model name: Intel(R) Core(TM) i7 CPU L 620 @ 2.00GHz
Package Versions: xorg-x11-server-Xorg.x86_64 1.9.4-1.fc14 xorg-x11-drv-intel.x86_64 2.12.0-6.fc14.1 kernel.x86_64 2.6.35.11-83.fc14
I've tried setting some X.org config stuff I've found search the web about this problem: (here quote from Xorg.0.log) [ 51.714] (**) Option "BlankTime" "0" [ 51.714] (**) Option "StandbyTime" "0" [ 51.714] (**) Option "SuspendTime" "0" [ 51.714] (**) Option "OffTime" "0"
But it seems nothing changed.
I am really happy for any pointers anyone can provide how to solve this.
Thank you in advance, Florian

How are the screen blanking options set in your screensaver? Totem can be set to override the screensaver in full screen mode; have you checked to see if it is?

Some laptops have settings in the bios that you have to set separately from the OS's settings.
Also, check system -> preferences -> screensaver and from that GUI, click on Power Management, which will pop another GUI In the second GUI, if the "put display to sleep when inactive for:" is set to NEVER then your screen will not be turned off. Also, beneath that is a check mark for Dim display when idle. If it is checked, AND screen saver is set to ACTIVATE after some time, then the screen will be dimmed (not same as turned off).

As near as I can tell, you need to use all of belt, suspenders, duct tape, and bailing wire to really turn off screen blanking.
1st check the screensaver. You may actually have two menu entries for screensaver, one for gnome, and the other for the tradition X11 screensaver. Make sure they are both turned off.
2nd check the power management options and tell it to never turn anything off. If it is a laptop, you may need to fiddle both the on AC and on battery pages.
3rd run gconf-editor (which you may have to install) and go to the key for /apps/gnome_settings_daemon/screensaver and uncheck the option to start the screensaver.
4th write a bash script that runs these commands:
xset s off xset dpms 0 0 0 xset -dpms
and add it to your startup scripts (make sure you chmod it to be executable).
If, after doing all that, the screen still blanks, then there probably is something in the BIOS you need to disable as well.

Ouh, ... writing a little script that moves the mouse a pixel every 9 minutes sounds easier to me now. [0] But ...

That did the trick! Thank you very much.

Wasn't there a thread last week, or the week before, about Gnome taking away your configuration options for the screen saver?
