Brian Chabot Posted October 11, 2007 Report Share Posted October 11, 2007 Just adding this as a tip, as it took me a while to get it to work, and even then it's not 100%... With an nVIDIA MCP61V chipset mobo (on-board GeForce 6100) and an Acer AL1716W LCD, Mandriva 2008, I tried to get it to run in the monitor's advertized 1440x900 resolution. The screen is ugly in that mode and the monitor rwesets to some wierd 1152x870 resolution with the desktop in 1440x900 making it stretched wrong and vertically beyond the edge of the monitor. I got it to work right in 1280x800 with the following xorg.conf: # File generated by XFdrake (rev 228555) Section "Extensions" Option "Composite" EndSection # ********************************************************************** # Refer to the xorg.conf man page for details about the format of # this file. # ********************************************************************** Section "ServerFlags" #DontZap # disable <Ctrl><Alt><BS> (server abort) AllowMouseOpenFail # allows the server to start up even if the mouse does not work #DontZoom # disable <Ctrl><Alt><KP_+>/<KP_-> (resolution switching) EndSection Section "Module" Load "dbe" # Double-Buffering Extension Load "v4l" # Video for Linux Load "extmod" Load "type1" Load "freetype" Load "glx" # 3D layer EndSection Section "InputDevice" Identifier "Keyboard1" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" Option "XkbOptions" "compose:rwin" EndSection Section "InputDevice" Identifier "Mouse1" Driver "mouse" Option "Protocol" "ExplorerPS/2" Option "Device" "/dev/mouse" EndSection Section "InputDevice" Identifier "Mouse2" Driver "evdev" Option "bustype" "0x0011" Option "product" "0x0006" Option "vendor" "0x0002" Option "HWheelRelativeAxisButtons" "7 6" EndSection Section "Monitor" Identifier "monitor1" VendorName "Acer" ModelName "Acer AL1716W" HorizSync 31-83 VertRefresh 56-76 # modeline generated by gtf(1) [handled by XFdrake] ModeLine "1280x800_120" 181.21 1280 1376 1520 1760 800 801 804 858 -HSync +Vsync # modeline generated by gtf(1) [handled by XFdrake] ModeLine "1280x800_100" 147.89 1280 1376 1512 1744 800 801 804 848 -HSync +Vsync # modeline generated by gtf(1) [handled by XFdrake] ModeLine "1280x800_85" 123.38 1280 1368 1504 1728 800 801 804 840 -HSync +Vsync # modeline generated by gtf(1) [handled by XFdrake] ModeLine "1280x800_75" 107.21 1280 1360 1496 1712 800 801 804 835 -HSync +Vsync # modeline generated by gtf(1) [handled by XFdrake] ModeLine "1280x800_60" 83.46 1280 1344 1480 1680 800 801 804 828 -HSync +Vsync # modeline generated by gtf(1) [handled by XFdrake] ModeLine "1280x800_50" 68.56 1280 1336 1472 1664 800 801 804 824 -HSync +Vsync EndSection Section "Screen" Identifier "screen1" Device "device1" Monitor "monitor1" DefaultColorDepth 24 Subsection "Display" Depth 8 Virtual 1280 800 EndSubsection Subsection "Display" Depth 15 Virtual 1280 800 EndSubsection Subsection "Display" Depth 16 Virtual 1280 800 EndSubsection Subsection "Display" Depth 24 Virtual 1280 800 EndSubsection EndSection Section "Device" Identifier "device1" VendorName "nVidia Corporation" BoardName "NVIDIA GeForce FX - GeForce 8800" Driver "nv" Option "DPMS" EndSection Section "ServerLayout" Identifier "layout1" InputDevice "Keyboard1" "CoreKeyboard" InputDevice "Mouse1" "CorePointer" InputDevice "Mouse2" "SendCoreEvents" Screen "screen1" EndSection Hopefully this will help someone else out there. And if anyone knows how to get this combination working in 1440x900 I'd love to hear it. [moved from Hardware by spinynorman] Quote Link to comment Share on other sites More sharing options...
scarecrow Posted October 11, 2007 Report Share Posted October 11, 2007 I think I have a better tip: The GPL "nv" driver is a big failure. Use the proprietary "nvidia" instead, and I can bet your 1440x900 will show up just great. Regards. Quote Link to comment Share on other sites More sharing options...
adamw Posted October 12, 2007 Report Share Posted October 12, 2007 Was the monitor detected as an AL1716W by Mandriva? Quote Link to comment Share on other sites More sharing options...
Brian Chabot Posted October 13, 2007 Author Report Share Posted October 13, 2007 Was the monitor detected as an AL1716W by Mandriva? Nope. The "Plug-n-Play" detection failed. But as scarecrow said above, the proprietary nvidia driver also solves the issue. Quote Link to comment Share on other sites More sharing options...

Looks like nv doesn't like 1440x900 with those refresh/sync rates. Quote Link to comment Share on other sites More sharing options...
scarecrow Posted October 13, 2007 Report Share Posted October 13, 2007 The "nv" driver is a PITA - this isn't a secret! Factly, the generic "vesa" driver is faster for me than "nv" in pretty much any puter with an old nvidia card... But if you are serious about your linux installation and want decent video performance, then you DO have to use the proprietary nvidia driver. Installation is rather easy, if you know what you're doing, and the performance boost is HUGE. Quote Link to comment Share on other sites More sharing options...
adamw Posted October 14, 2007 Report Share Posted October 14, 2007 Brian: can you run this command as root at a console: monitor-edid --MonitorsDB and paste the output here? I can then get it added to the detection database for future releases. Quote Link to comment Share on other sites More sharing options...
