Figuring out how to control screen blanking is a common problem for me,
depending on hardware. I think I recall several ways screen
blanking/power saving can be set: in the BIOS, on the monitor OSD, in the
graphics device settings, in a .conf for X, or with xset as you mentioned,
and also in some of the gui power saving management center operations
headquarters.
Also, there was a discussion here lately about console-setup IIRC, but I
never got much into it. I think that only applies when you are in a TTY
outside of the X session.
The thing you'll have to do is find out what is blanking the screen. If
moving a mouse, or hitting space won't wake the monitor, try turning the
monitor power off and on to start. On my older machines, I have sometimes
disabled all the BIOS settings for power savings, but then again some
machines seem to pass on some of those settings to the OS, so I often just
load setup defaults and try that first.
