Screen Stays Blank

[olograph]

Hello, I'm quite good in computers but a huge noob in linux.

I installed the latest ubuntu server amd64for my NAS and everything goes lovely except if I leave the console for too long, the screen goes blank and says no signal.

The server's still on... e.g.: I can access my webmin page.

There's no way I can access the console back through the keyboard, I can only restart...

Tell me if you need more info.

Thanks

sudo nano /etc/default/grub

Look for [GRUB_CMDLINE_LINUX_DEFAULT] and add to the end:

acpi=off apm=off

Update Grub:

sudo update-grub

Reboot:

sudo shutdown -r now

I forgot to mention, when the system boots the screen is also blank. It does that half the time and I have to enter through recovery mode which works marvelously.

I did what you proposed, can't test it till I get to boot by trial and error.

Is there something to do with my screen being blank on startup?

Can you provide more information about your hardware? My guess would be that it is a problem with the graphics card.

You can try it in recovery mode, you just don't need sudo cause you should be root.

Thanks a lot wojox.

I added nomodeset, recommended for blanks screen on boot along with the acpi=off and apm=off settings for the screen going blank to the grub file and all works like a charm now.
