is there a command line way to control when screen blanks? fedora 17


when i do backups i boot from a live fedora 16 or 17 cd

i boot to level 1 and use dd and sometimes fdisk

to my frustration while dd is running the screen goes blank - maybe after 5 min

if i were in the graphical mode i know how to tell the system not to do this

i suppose i could boot to the graphical mode (takes a lot of time on a cd) and set the parameter and then use terminal - but more convenient if there is a way to reset this timeout parameter from the command line

any suggestions?

maybe that means that the command line you get when you boot to level 1 is not an X window?

alternatively maybe it means something particular about with my terminal?

I would be surprised if level 1 involved X windows - and from its name I would assume xset is an X windows command- since level 1 is supposed to be a minimal environment - like the old unix environment of 10-20 years ago

I would imagine that in level 1 the shell would be issuing writes to a driver that merely writes to the screen

Any know how would be appreciated

The blanking it due to the monitor's dpms feature, not the screen saver, so you have to use the xset options that control that.
