[SOLVED] make refresh rate persistent, nvidia GT9600 card

coyopil · 08-17-2012, 04:38 PM

I'm using an xorg.conf file that worked until about a month ago when I made a couple changes, 3.2 kernel and new nvidia driver version. Wanted to see if newer kernel could handle a new Huawei dongle, which it could not --

Anyway, now I can no longer get 85 hz refresh rate to stick between reboots.

I tried the gtf command.
That gave me a different modeline.

gtf 1280 960 85

# 1280x960 @ 85.00 Hz (GTF) hsync: 85.68 kHz; pclk: 149.43 MHz
Modeline "1280x960_85.00" 149.43 1280 1376 1512 1744 960 961 964 1008 -HSync +Vsync

Now setting the Automatic refresh rate in KDE settings/Nvidia settings results in 85 hz refresh rate.
