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.
Hi Nigel, Thanks for the info. This is desktop computer and I am using 17" samsung SyncMaster 753DFX CRT monitor. Previously I noticed that fedora used to set it to 85Hz at 1024x768. I guess internally its set to right values because I don't have flickering problem in my monitor. Only KDE is reporting a wrong value. May be its just have something to do with KDE Desktop and Power management feature. Thanks again
