Hi Deepak. To stop the monitor going into standby, and I presume this is on a
PC, not a laptop, you can comment out the DPMS line in /etc/X11/xorg.conf.
su to root in a terminal, open a text editor, gedit, kwrite, or something,
then go to /etc/X11/xorg.conf . You'll find the "dpms" line in the monitor
section. Just put a # at the start of the line. Save the change, and exit
the text editor.
ctrl+alt+backspace will shutdown the Xserver, and bring you back to your
log-in screen. Login, and the monitor should now stay up.
Not sure about the odd large "X" screensaver. I too have seen that and
sometimes when I move the mouse it goes away to be replaced by another
screensaver, presumably the default KDE one.
Not sure about your post about the 50hz refresh rate. I did read that LCD
screens run at 60hz. Perhaps if your using a crt screen, X is wrongly
identifying it as an lcd one.
While your in xorg.conf sorting out the dpms thing, check whether you have 2
lines in the monitor section showing something like, and this is mine on FC5
below.
HorizSync 30.0 - 92.0
VertRefresh 48.0 - 120.0
Don't just use those values above. You need to check your monitors values, but
those above set my Compaq P700 CRT monitors to 68.6kHz, and 85Hz at a
resolution of 1024x768. (17" monitor).
dpms=display power management signalling
Hope some of that helps.
Nigel.
