The last is above the maximum 50 for your monitor, so it gets removed, and you get lines like: > (--) SVGA: Mode "640x480" needs hsync freq of 53.01 kHz. Deleted. Now, your card sez: > Section "Device" > Clocks 25.18 Which means that it only supports a "dot clock" rate of 25.18. Since the first 3 modelines require minimum dot clocks of 31.5, 31.5, and 36 respectively, none of them are valid, and get thrown out. Then, the system falls back to a builtin 320x200, which is probably within your device/monitor capabilities. If your video card really does support high res mode, then you will need to get a correct `Clocks' line for your card. If not, then you might want to look at the `Doublescan' section of the modelines. -- Jonathan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
