I am relatively new user (ubuntu 11.10) and I am facing a strange problem!!! Yesterday I was running a programme called liggghts for dem simulation. It was supposed to run overnight. In the morning when I came my screen was on but there was no display!! I tried to wake it up but in no avail!!

I have already uninstalled the screensaver, put the suspend in power options to dont suspend and in screen settings to turn off never. Could anybody kindly advice me regarding the same!!!! I have saved the log files. Please let me know if you need some thing.

Please help!!! I really want to stay away from windows, I love linux but this problem alone is making me crazy!!!
