Created attachment 76277 [details] boot - change to 60Hz - change to 75Hz but my monitor is still at 60 Hz Hi, I'm using Linux Mint 14 MATE x64 kernel 3.5.0-25 with a NVIDIA GeForce GTX 460 video card and a ViewSonic VG1921wm monitor. Using the NVIDIA privative driver I can set the monitor resolution to 1440x900 @ 75Hz in Menu > Preferences > Display. Then with the monitor buttons I look in Information and it says that vertical frequency is 74.8Hz, and when I set it to 1440x900 @ 60Hz, the monitor says that vertical frequency is 59.9Hz, namely: all works well. But when I'm using Nouveau it has no effect, whatever I set in Menu > Preferences > Display the information of my monitor always shows a vertical frequency of 59.9Hz. What can I do in order to get the real 1440x900@75Hz resolution with Nouveau?

You should be able to select the right ones by sticking stuff in your xorg.conf or by doing something like xrandr --output DVI-I-1 --mode 1440x900 --refresh 75 (or maybe --mode "1440x900"x75) If you're still having trouble, feel free to re-open and provide the output of "xrandr -q".
