Becoming a bit annoyed here. Using the graphical configuration tool for KDE, I have disabled power management stuff. This is a desktop for my personal use, and I am not interested in monitor blanking. The screen, however, continues to blank.
I have determined that the culprit is DPMS. xset q output shows that DPMS is enabled.
Ubuntu 12.10 quantal: On login, I run "xset -dpms s 0 0 s off". This works great until I suspend and resume. For some reason, dpms is re-enabled after resume. Is there an easy way to completely disable DPMS without recompiling X?
