[SOLVED] gnome-screensaver is active but display is asleep?

[unebaguettesvp]

i don't know how else to explain it. this only started happening when i bought a new video card yesterday. i tried to search the forums but i don't know what to search for.

i want gnome-screensaver to activate when i leave my computer. it used to just turn on automatically after 10 minutes. now, after i installed a new video card, the screen turns black. i know it is running because if i touch the mouse VERY slightly it MIGHT come on. so, it's almost like the display is turning off even the gnome-screensaver is running.

so, i have my screensaver settings set to a random screensaver theme, it turns idle after 10 minutes and the activate screensaver when computer is idle checkbox is checked. the lock the computer checkbox is not. these are the same settings before i got the new video card. also, in power management put the computer to sleep when inactive is set to never. put display to sleep when inactive is also set to never. again, i haven't changed these settings.

what has changed is my video card and my xorg.conf:

i know this might seem stupid but i need to get this working so my lcd screen doesn't get any ghost images!

any suggestions on what i could try? thanks!

[unebaguettesvp]

i tried a few other things.

commenting out Option "DPMS" in my xorg.conf did nothing.

i used to use an ati radeon aiw 9800 pro. that's when gnome-screensaver was properly working. i used to have my projector hooked up to the dvi to vga connector. now i have an nvidia geforce fx 6200 and i had the projector hooked up to the vga connector. i switched it to the dvi to vga connector and it still produces the same result.

i set the gnome-screensaver to go off after 5 minutes. and it does!!! but after another 5 minutes with the gnome-screensaver going, the screen goes black. if i tap it lightly i can bring back the screensaver.

so, i'm pretty convinced that the projector is turning off. any ideas on how to make it stop?

more information, i installed the driver for nvidia using envy.

changing "Put display to sleep when inactive for" from Never to 1 hour did nothing as well.

sorry for the bump. any ideas? i'm running out. my knowledge is limited to whatever is a gui.

[unebaguettesvp]

damn it! i found this:

https://bugs.launchpad.net/ubuntu/+s...ver/+bug/46575

and then this:

http://www.unet.univie.ac.at/aix/cmds/aixcmds6/xset.htm

so, i tried this:

xset s noblank

that didn't do anything! ARGHHHHH!!!! any help?

I'm having the exact same problem.

Just installed XUbuntu 7.10 Gutsy - using the restricted drivers for my GeForce 7600GT. When it's time for the screen-saver to start, the screen just goes blank. I move the mouse and it goes right back to the desktop. If I remove the restricted driver, OpenGL applications chug along.

Any input would be greatly appreciated!

[unebaguettesvp]

i haven't tried that yet. so, if you remove the restricted drivers, gnome-screensavers work just like normal? if that's true, then it definitely has something to do with nvidia. did you install the restricted drivers with envy or from the gnome main menu? i couldn't get the main menu to work properly.

also, how is your 7600 GT card? i just ordered one! is it fast?

[unebaguettesvp]

sorry for the bump but does anyone have any ideas?

[unebaguettesvp]

fixed it! add this to your xorg.conf:

Section "ServerFlags"
	Option "blank time" "0"
	Option "standby time" "0"
	Option "suspend time" "0"
	Option "off time" "0"
	Option "screen blank" "0"
EndSection

and restart X. <CONTROL><ALT><BACKSPACE>

Nice work! I'll try this when I get home.

The 7600GT is a great budget card. I've had it for a little less than a year... runs Battlefield 2 and any Source-engine game just fine (mine's an XFX Fatal1ty), though I did replace the HSF with something from Zalman because it was crazy-loud.

Now my screen won't go blank at all.
