| Monitor Sleeping On occasion, the my monitor is going to sleep and cannot be awaken (Nvidia 8500 GT latest drivers, Kubuntu 12.04 LTS). The only way to recover is to reboot. Wired mouse appears to be active; however, monitor/keyboard are sleep. Any ideas? |

| I am running Ubuntu Precise but had the problem you describe with Pangolin. I just checked my display settings and my sleep policy is set to "never". If I remember correctly I researched the problem and never found a resolution. I can turn off my LG display with a soft button. My neighbor runs Win XP and was having a similar problem. I just set his sleep policy to never as well. |

Go in to the power settings and turn off sleep. In my experience with older hardware, sleep and hibernate support in Ubuntu is very hit-or-miss.

Howdy,
I've had similar issues and at times, I still do. I'm not 100% on the solution because it happens so infrequently but I believe I restart x11vnc /and/ I VNC to the machine. But I'm not certain .... :\
Cheers,
-pablo

I'm leaning towards Maxo's analysis but had a similar problem on a desktop running KDE where the gui configurations I could find were not keeping the monitor from blanking off.
man xset
has the syntax and options. What I used was
xset -dpms
It's a per-session so I added it to the KDE startup scripts or /etc/rc.local but I don't currently need it. |

Since I've updated to the latest Nvidia video driver (post original post), I've not observed this issue. Will continue to monitor. Thanks for your input. |
