Hello Thank Thomas for your reply and thanks to everyone else. So, here's my output from running xvidtuner: Vendor: Monitor Vendor, Model: ViewSonic PF790 Num hsync: 1, Num vsync: 1 hsync range 0: 30.00 - 97.00 vsync range 0: 50.00 - 160.00 "1280x1024" 157.50 1280 1332 1492 1728 1024 1025 1028 1072 +hsync +vsync So I try and add this to my /etc/X11/XF86Config file: Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "ViewSonic PF790" DisplaySize 360 270 HorizSync 30.0 - 97.0 VertRefresh 50.0 - 160.0 Option "dpms" #"1280x1024" 157.50 1280 1328 1488 1732 1024 1025 1028 1072 +hsync +vsync EndSection Of course the line I added is commented out because if I were to add it gives me a message saying that it didn't understand the line that I added. Am I suppose to add something like "option" somewhere. In the windows system it seems like the refresh rate is set at the max which is 85Hz but in linux I dunno what it's set at. Linux was really nice and it already knew my monitor type and set up all the settings for it already. Thanks a bunch Regards Desmond -----Original Message----- From: xfree86-list-admin@xxxxxxxxxx [mailto:xfree86-list-admin@xxxxxxxxxx] On Behalf Of Thomas Dodd Sent: Thursday, September 04, 2003 1:37 PM To: xfree86-list@xxxxxxxxxx Subject: Re: tweaking desktop.... xvidtune?

But I tried this in > redhat 9.0 and got no love. instead it couldn't even run the Xserver. Can you post the Modeline you got from xvidtune and you XF86Config file? Also, the log file when X won't start would help too. Best to start X form runlevel 3, so gdm doesn't keep trying to start X. It should work, but the Modelines are a but different in XF86 4+. I have one in my XF86Config file that works fine. -Thomas _______________________________________________ xfree86-list mailing list xfree86-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/xfree86-list IRC: #xfree86 on irc.redhat.com _______________________________________________ xfree86-list mailing list xfree86-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/xfree86-list IRC: #xfree86 on irc.redhat.com
