Ok, I'll admit I'm not much of a genius when it comes to modifying xorg.conf. Every time I get a newish piece of hardware I am reminded of this. My setup includes a Biostar board with an onboard nVidia Geforce 8200. My LCD is an Acer 22" with native resolution of 1400x1050. Distro is Debian Lenny, if that matters. Whenever I get into a bind with my xorg.conf, I pop in Knoppix to let its auto-configurator tool generate me a nice xorg.conf. Then I take and modify that for my system, as Knoppix doesn't always pick the best settings, but they at least work and give me a template to start hacking. I want to add 1400x1050 as a resolution, but for some reason it just won't accept it. SubSection "Display" Depth 16 Modes "1600x1200" "1400x1050" "1280x1024" "1024x768" "800x600" "640x480" Defaults to 1600x1200 when I start X (duh). If I remove the 1600x1200 line: SubSection "Display" Depth 16 Modes "1400x1050" "1280x1024" "1024x768" "800x600" "640x480" It defaults to 1280x1024. I have Modelines configured for 1400x1050: ModeLine "1400x1050" 122.61 1400 1488 1640 1880 1050 1051 1054 1087 -HSync +Vsync ModeLine "1400x1050" 149.34 1400 1496 1648 1896 1050 1051 1054 1094 -HSync +Vsync ModeLine "1400x1050" 155.85 1400 1496 1648 1896 1050 1051 1054 1096 -HSync +Vsync ModeLine "1400x1050" 179.26 1400 1504 1656 1912 1050 1051 1054 1103 -HSync +Vsync ModeLine "1400x1050" 214.39 1400 1512 1664 1928 1050 1051 1054 1112 -HSync +Vsync But no go. Any ideas? I've posted my xorg.conf on Pastebin: http://pastebin.com/m4db91abc Thanks, Brian
