You said later you are still learning whereas this kernel version number, unless Ubuntu have invented their own numbering scheme, is a development work-in-progress and therefore for people developing the kernel and the brave. The latest stable version is 2.6.28.6.
is IDLE for long enough to turn the monitor "off", the monitor goes into standby fine (green light turns to orange light) but every so often the monitor will boot up again, and flash up on the screen "No Signal" and go back to standby mode... there seems to be no consistency to it, it is very random..
Odd, I have seen cases where the first stage of power saving is activated and then when the next stage activates the monitor briefly gives this message.
However as I dual boot with windows, I was able to identify that the monitor works fine in windows, and I haven't had these problems before..
Do you use GNOME. There was an issue with GNOME and Debian a while back because GNOME moved the monitor DPMS powersaving functionality from gnome-screensaver to gnome-power-manager and for a brief period Debian testing had versions of those two packages where the functionality had disappeared completely, i.e. had the newer gnome-screensaver that had lost the DPMS functionality and the older gnome-power-manager which had not gained it.
I reported this as a debian bug - http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=370692 and since then other related issues have been discussed in this bug report and links to more information provided. It may be worth a look.
