Hi,
I have reinstalled Debian, and visibly
my Monitor turns off.
Similarly to the DPMS OFF.
I can still do SSH, and I typed:
vbetool dpms on
as indicated here, but the monitor does not turn ON again..

What would you suggest?
thanks in advance
edit: if I do over ssh (su): echo 3 > /proc/acpi/sleep
then the all pc is crashed !
cold reset
Code:
(2) systems where it is possible to call the video BIOS during S3
resume. Unfortunately, it is not correct to call the video BIOS at
that point, but it happens to work on some machines. Use
acpi_sleep=s3_bios.
(3) systems that initialize video card into vga text mode and where
the BIOS works well enough to be able to set video mode. Use
acpi_sleep=s3_mode on these.
(4) on some systems s3_bios kicks video into text mode, and
acpi_sleep=s3_bios,s3_mode is needed.
(5) radeon systems, where X can soft-boot your video card. You'll need
a new enough X, and a plain text console (no vesafb or radeonfb). See
http://www.doesi.gmxhome.de/linux/tm800s3/s3.html for more information.
Alternatively, you should use vbetool (6) instead.
(6) other radeon systems, where vbetool is enough to bring system back
to life. It needs text console to be working. Do vbetool vbestate
save > /tmp/delme; echo 3 > /proc/acpi/sleep; vbetool post; vbetool
vbestate restore < /tmp/delme; setfont <whatever>, and your video
should work.
