Same here (current hardy, nvidia driver, external LCD Samsung XL20). $ xset -q | grep -A1 DPMS DPMS (Energy Star): Standby: 0 Suspend: 0 Off: 0 DPMS is Enabled Monitor is On
$ xset dpms 20 0 0 Then the screen blanks after 20 secs and then turns on again as the LCD searches the input signal and after a few seconds goes to standby (i.e. the LED backlight + fan are switched off). -- screen doesn't switch off by itself https://bugs.launchpad.net/bugs/207553 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
