http://ubuntuforums.org – Hi, First of all ,I know this is about the binary driver so it's not supported. I am just asking for your experience with it maybe someone can help me. My new ATI Radeon HD 4350 is having some problems in Ubuntu 9.04. My CRT monitor supports 1024x768@85Hz and 1152x864@70Hz but they are not auto detected by the catalyst control center. On windows, I had an option to override the detection and use the refresh rates I specify. I can't find such an option in ubuntu. I tried entering the values manually in the xorg.conf but apparently they only take effect in the gdm. As soon as I login display is back to 60Hz which is the maximum auto detected value. I need to know how I can force ATI CC to use the higher refresh rates or at least not change what I have specified in xorg.conf. Thanks in Advance, Joe Here's how my xorg.conf looks: Code: Section "ServerLayout"         Identifier    "aticonfig Layout"         Screen      0  "aticonfig-Screen[0]-0" 0 0 EndSection Section "Files" EndSection Section "Module" EndSection Section "ServerFlags"         Option            "Xinerama" "off" EndSection Section "Monitor"         Identifier  "aticonfig-Monitor[0]-0"         HorizSync    30.0 - 69.0         VertRefresh  50.0 - 120.0         ModeLine    "1152x864_70.00" 96.8 1152 1224 1344 1536 864 865 868 900 -hsync +vsync         Modeline    "1024x768_75.00"  81.80  1024 1080 1192 1360  768 769 772 802  -HSync +Vsync         Option            "VendorName" "ATI Proprietary Driver"         Option            "ModelName" "Generic Autodetecting Monitor"         Option            "DPMS" "true" EndSection Section "Monitor"         Identifier  "0-CRT2"         Option            "VendorName" "IBM"         Option            "ModelName" "E74"         Option            "DPMS" "true"         Option            "PreferredMode" "1152x864"         Option            "TargetRefresh" "70"         Option            "Position" "0 0"         Option            "Rotate" "normal"         Option            "Disable" "false" EndSection Section "Device"         Identifier  "aticonfig-Device[0]-0"         Driver      "fglrx"         Option            "Monitor-CRT2" "0-CRT2"         BusID      "PCI:1:0:0" EndSection Section "Screen"         Identifier "aticonfig-Screen[0]-0"         Device    "aticonfig-Device[0]-0"         Monitor    "aticonfig-Monitor[0]-0"         DefaultDepth    24         SubSection "Display"                 Viewport  0 0                 Depth    24                 Modes    "1152x864" "1024x768"         EndSubSection EndSection (Hardware)
