13.10 Screen flickers

[valley96]

I just upgraded to 13.10 and I now have my main monitor on my laptop flicker every few seconds. It doesn't seem to affect my second monitor. It doesn't seem to happen if I'm using it so I suspect it's trying to go in to a blank screen or something.

I found this section on the ubuntuguide.org site:

Screen Keeps Flickering
If you have an Intel Corporation Mobile 915GM/GMS/910GML card, your screen may flicker every 5-10 seconds. To prevent this:
Menu -> System -> Administration -> Advanced -> Service Manager -> Uncheck "Detect RANDR (monitor) changes"

This seems to address my problem but I don't believe the service manager exists anymore...or at least I can't find it. Any help would be appreciated.

DELL XPS702 i7
Nvidia GeForce GT 555M/635M
Intel integrated graphics controller

Thanks.

Same problem and also can't find "Menu -> System -> Administration -> Advanced -> Service Manager -> Uncheck "Detect RANDR (monitor) changes".

i solved my own problem: used synaptic to install the nvidia-cuda-toolkit and problem solved! no more flickering.

Hi, I'm wondering how would that solve the issue. Isn't cuda toolkit a development SDK?
Thanks
