Version: unspecified (using KDE 4.4.95) OS: Linux The problem in the next — if the screen saver is not needed for me, I cant disable it with KDE tools. If screensaver is disabled (even if kscreensaver is not installed), my monitor is still turns off after 10 minutes of idle. Xset shows to me that the screensaver is still enabled: DPMS (Energy Star): Standby: 600 Suspend: 600 Off: 600 DPMS is Enabled Monitor is On So, to completely disabling the screensaver I should add this command: "xset dpms 0 0 0 s noblank s noexpose s 0 0" in autostart. Reproducible: Always Expected Results: If the screen saver is disabled in KDE settings, X11 screen saver should be disabled automatically, or KDE's screensaver settings window should contain some advanced options to control all of these behaviours.
Oops, sorry, I copied a wrong section. This is what xset -q shows about screensaver: Screen Saver: prefer blanking: yes allow exposures: yes timeout: 0 cycle: 600
But DPMS management has the same trouble, btw.
Marking as invalid, as the DPMS config is not in the screensaver, and the 2 options are completely separated. Please find your DPMS management settings in Power Management in System Settings: disabling them will give you the desired effect. (In fact, what you reported says the screensaver is disabled and DPMS start after 10 mins)
