Read screenblank(1) man page. By default is set to 600 seconds (10 minutes).

You might reconsider running X at a lower resolution and/or with a lightweight tiling window manager; I'm able to do this on a 533 MHz Via box with 512MB RAM and it seems just fine with a few XTerm windows, especially if you use screen or tmux.
Regarding the display: you might check for options in the BIOS to use instead of the ACPI stuff, and/or using a display OFF function key if available. Most laptops at least have a display switcher for use with external monitors; that can sort of act as a display toggle for you. Good luck! |

Thanks for solutions you give, but ... screenblank(1) is only make screen blank, don't turn off it. Screen still have a background light. I look in all the BIOS and there's no option for display. Another thing - I don't have power off button for display only, I don't have switch button for display too ... and don't wanna run any X. I can run xdm, it's a kind of X Login screen, whitout run X, but this is not a solution - this is avoidance of the problem. I think maybe with ACPI stuff I can do something, but ... I don't find a way. Here is my sysctl acpi output:

Try pressing FN+F4 - that's the display toggle for your model.
If that doesn't work, maybe try FN + F1 until display goes blank? It may not fully blank. There are various scripts under /etc/powerd that you might be able to make use of, specifically faking a "lid close" event which should blank the screen. Good luck! |

I have been enjoying the new vesa implement, but have noticed some problems on older machines (vintage crap Neomagic). When I exit an X session the screen is blurred. Anyway, if you find that your problem goes away without vesa it could narrow the problem down really fast. |

I've been experiencing the same problem with various 6.x.x NetBSD installations on a few ASUS laptops/netbooks. Reboot works fine, but halt doesn't power off system, I'm forced to do it manually.

P.S. I have the same problem in VMWare as well.

It needs to be compiled in the kernel. Quote:
NetBSD Poweroff tutorial NetBSD Power management Document Maybe not a VESA issue after all. Sorry, guys. Might not hurt to see what happens without VESA, if the screen problem persists. Last edited by fn8t; 15th February 2015 at 02:04 AM. Reason: spelt apm amp |

Thank you fn8t for your tip! Strange it's not enabled by default. I will test it and let you know how it went.
