Hi, I have got a LCD, too, and I experienced very good results when I entered the *exact* refresh rate(s) supported by the LCD display. As far as I know you can solve your problem in the way that you just type in ONE rate. So X won't look for other rates. (Others may correct me.) The config file is /etc/XF86Config Here you can enter vertical and horizontal rates. And here a show you a part of my /etc/XF86Config file. Note, that I entered just one rate and that I entered it exactly as shown in my LCD manual (as a fraction): #... # ********************************************************************** # Monitor section # ********************************************************************** # Any number of monitor sections may be present Section "Monitor" #must be the same name like in Screen's section below: Identifier "Novita" VendorName "Novita" ModelName "" Option "dpms" # HorizSync is in kHz unless units are specified. # HorizSync may be a comma separated list of discrete values, or a # comma separated list of ranges of values. # NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S # USER MANUAL FOR THE CORRECT NUMBERS. HorizSync 63.981 # HorizSync 30-64 # multisync # HorizSync 31.5, 35.2 # multiple fixed sync frequencies # HorizSync 15-25, 30-50 # multiple ranges of sync frequencies # VertRefresh is in Hz unless units are specified. # VertRefresh may be a comma separated list of discrete values, or a # comma separated list of ranges of values. # NOTE: THE VALUES HERE ARE EXAMPLES ONLY.
