I am new to FreeBSD and installed the 6.0-RELEASE on an AMD64 with a Nvidia GeForce 6600 GT graphics card and a Samsung SyncMaster 930BF 19" TFT. My problem is that the vertical refresh rate seems stuck at 60Hz and the horizontal sync rate at 63.8kHz. This causes serious eye strain and I can't use the system for very long before I get a headache. The optimal settings for this monitor is 1280x1024 with hor. 80kHz and vert= . 75Hz which I can get when I plug it into a win2k box and load the Samsung drivers. I am using the open-source nv drivers for the gpu.(can't find nvidia proprietary that support 6.0-RELEASE on AMD64) My X-server setup works fine but the xorg.conf configurations don't have an impact on the refresh and sync rates. I have tried the following settings in xorg.conf: ---------------------------------------------------------------------------= -------------------------- Section "Monitor" Identifier "Monitor0" VendorName "SAM" ModelName "SyncMaster" HorizSync 80-81 VertRefresh 75-75 EndSection Section "Modes" Identifier "1280x1024" ModeLine "1280x1024" 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync EndSection ---------------------------------------------------------------------------= -------------------------- I've also tried without the "Modes" section and HorizSync values of 30-81 and VertRefresh values of 56-75 when I Xorg -config xorg.conf.new X works fine and but the OSD still shows the HorizSync to be 63.8 and VertRefresh 60 (on the windows box the OSD displayed the correct rates after driver setup) my /var/log/Xorg.0.log has the following lines of output: (--) NV(0): Virtual size is 1280x1024 (pitch 1280) (**) NV(0): *Default mode "1280x1024": 135.0 MHx, 80.0 kHz, 75.0 Hz (II) NV(0): Modeline "1280x1024" 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync there is also a section in the log: (II) NV(0): Supported VESA Video Modes: .. (II) NV(0): 1280x1025@75Hz .. My "screen" configuration in the xorg.conf file is as follows: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1280x1024" EndSubSection EndSection I would greatly appreciate it if someone can point me in the right directio= n on this since with the current settings my system is unusable to me.
