http://askubuntu.com – I am running Ubuntu 12.10 on an HP Pavilion dv9000 with the MATE DE. For some reason my screen keeps going to sleep (going blank) after 10 minutes of being idle, but I have the screen saver turned off and I have the power settings set to NEVER turn off or dim the monitor. I also checked to make sure that there wasn't a setting in the BIOS that could be doing this and there are no power saving settings in my BIOS. This problem seemed to begin happening after a recent automatic software update, so it seems like it's a bug in the OS. Also, someone here posted on a similar thread that enter (HowTos)
