To finally close the topic: There are several solutions to the previous described problem. First off all the BIOS should be checked for the powermanagement settings --- in case this is not already checked (thanx to george, but, this was also my first thing I did :-). DOS/Windows seems not to be an indicator for the powermanagement settings, as "Kal." told me. 1) terminal-mode (i.e not under X11): setterm -blank 0 ## thanx to Tomek OR 2) starting X11: xinit -s 0 ## thanx to Christophe ## not tested by me, but I'm sure it'll work OR 3) while running X11: xset s off ## thanx to man xset ;-) ## (damned I didn't mentioned this before starting this mail-lawine :-) ## seems to be a clean solution because it may be placed into $HOME/.xinitrc ThanX again to everybodies quick response and help!
