 Posted: Thu Aug 23, 2007 2:14 pm Post subject: Monitor refresh rates: xrandr vs. xorg.conf |
 |
|
My monitor can do 85 Hz with 1024x768. This is reported by the xrandr tool and it works without problems. However, the X server always starts up at 75 Hz and I have to change it with xrandr. I was wondering if this could be because in xorg.conf, the refresh rate range does not go up to 85. I copied the values straight from the manual for my monitor, so I know they're correct. Would it be safe to push those values higher to see if it will let 85 Hz be selected automatically?
This is with GeForce4 FX 5500, the nv driver, 17" CRT monitor, latest stable X.org. |

| Can you post your /etc/X11/xorg.conf, because maybe you have insert an invalide hoz refresh or vert refresh rate and X.ORG just ajust to the best possible value. |

Looks like the horizontal sync actually only goes to 70, so who knows why 75 Hz was the actual setting the X server came up in.

#HorizSync 30-70
#VertRefresh 50-180
