Hardy: Screen still goes blank even with power saving set to 'Never'

[jimv]

My laptop screen still goes blank after awhile when plugged in, even though I've set the Power Saving control panel to never blank the screen. To add an even odder bit, if I move the mouse a few minutes after it goes blank, then the screen comes back up. But if I wait about 20-30 minutes before moving the mouse, the screen doesn't come back on until I restart the X server.

Any ideas?

I thought I was the only one having this problem. I constantly have to keep restarting the laptop for it to become active again. I would love a solution to this as it's driving me a bit insane.

I think I may have found a solution. I was googling around and found some guy who said to add these lines to your xorg.conf (back it up first

Section "ServerFlags"
	Option	"BlankTime"	"0"
	Option	"StandbyTime"	"0"
	Option	"SuspendTime"	"0"
	Option	"OffTime"	"0"
EndSection

If you already have options in that section, you can leave them in. I didn't test it yesterday when I made the change, but I'll try to watch and see if the screen goes off today.

Ok, so I fully tested this out this morning and after the screen goes "blank" I have NO way of "waking" it up to input my password. I have to ctrl-alt-backspace to get back into the system. I am almost at wits end with this anyone have another suggestion?

Does it help if you type the following on the command line before playing video?

sudo /etc/init.d/laptop-mode stop

You can undo this afterwards with

sudo /etc/init.d/laptop-mode start
