hello everyone, i must miss something easy here... fresh fedora 15 install: i can't get my monitor to switch to 120 Hz (it did with fedora 14 though). the gnome "Displays" app (system settings) doesn't display any refresh rate. i tried some xrandr commands without success... gtf 1920 1080 120.0 gives the corresponding modeline xrandr --newmode "1920x1080_120.00" 368.76 1920 2072 2288 2656 1080 1081 1084 1157 -HSync +Vsync xrandr --addmode DVI-D-1 1920x1080_120.00 screen goes grey for half a second and returns to normal ; now there is a * next to the new mode xrandr --output DVI-D-1 --mode 1920x1080_120.00 doesn't switch to 120Hz ; OSD effectively reports the refresh rate is still 60Hz the hardware is a lenovo t61p with docking station using dvi output. video card: nvidia quadro 570M. monitor: viewsonic v3d 241 wm led 120 hz. thanks for this very nice linux distribution by the way ! have a great day ! pierre -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
