Hi, I got the solution to reach 120Hz I need to use the following command: xrandr --output DVI-I-1 --set "scaling mode" None Thanks <div class="gmail_quote">2012/7/6 Maarten Maathuis <<a href="mailto:madman2003@gmail.com" target="_blank">madman2003@gmail.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">If you look at "xrandr --verbose" you will see an property that is called "scaling mode", set that to none and that should give the same effect. But i still get the impression that the 120Hz mode doesn't even stick, regardless of whether it's using the native mode or not. <div class="HOEnZb"><div class="h5"> On Fri, Jul 6, 2012 at 9:52 AM, HacKurx <<a href="mailto:hackurx@gmail.com">hackurx@gmail.com</a>> wrote: > For 120Hz with nvidia driver I had to disable the following option: > <a href="http://img15.hostingpics.net/pics/250362Nvidia120Hz.png" target="_blank">http://img15.hostingpics.net/pics/250362Nvidia120Hz.png</a> > > "Force Full GPU Scaling". > > Thanks > > 2012/7/6 HacKurx <<a href="mailto:hackurx@gmail.com">hackurx@gmail.com</a>>: >> Thank you for your reply, I tried but it does not change, here is what >> appears in my log : >> >> [ 428.160] (II) NOUVEAU(0): EDID vendor "SAM", prod id 1258 >> [ 428.160] (II) NOUVEAU(0): Using hsync ranges from config file >> [ 428.160] (II) NOUVEAU(0): Using vrefresh ranges from config file >> [ 428.160] (II) NOUVEAU(0): Printing DDC gathered Modelines: >> [ 428.160] (II) NOUVEAU(0): Modeline "1680x1050"x0.0 119.00 1680 >> 1728 1760 1840 1050 1053 1059 1080 +hsync -vsync (64.7 kHz eP) >> [ 428.160] (II) NOUVEAU(0): Modeline "1680x1050"x0.0 238.46 1680 >> 1728 1760 1840 1050 1053 1059 1080 +hsync +vsync (129.6 kHz e) >> [ 428.160] (II) NOUVEAU(0): Modeline "1680x1050"x0.0 218.59 1680 >> 1728 1760 1840 1050 1053 1059 1080 +hsync +vsync (118.8 kHz e) >> [ 428.160] (II) NOUVEAU(0): Modeline "1680x1050"x0.0 198.72 1680 >> 1728 1760 1840 1050 1053 1059 1080 +hsync +vsync (108.0 kHz e) >> >> Thanks >> >> 2012/7/5 Maarten Maathuis <<a href="mailto:madman2003@gmail.com">madman2003@gmail.com</a>>: >>> On Thu, Jul 5, 2012 at 8:38 PM, HacKurx <<a href="mailto:hackurx@gmail.com">hackurx@gmail.com</a>> wrote: >>>> Hello, >>>> >>>> Can you help me? >>>> I cannot use 120Hz on my Samsung 2233RZ with nouveau. >>>> >>>> My xorg.conf : >>>> <a href="https://forums.gentoo.org/viewtopic-t-929124.html" target="_blank">https://forums.gentoo.org/viewtopic-t-929124.html</a> >>>> >>>> Thanks >>>> >>>> Best regards, >>>> >>>> HacKurx >>>> <a href="http://www.hackurx.info" target="_blank">www.hackurx.info</a> >>>> _______________________________________________ >>>> <a href="mailto:xorg@lists.x.org">xorg@lists.x.org</a>: X.Org support >>>> Archives: <a href="http://lists.freedesktop.org/archives/xorg" target="_blank">http://lists.freedesktop.org/archives/xorg</a> >>>> Info: <a href="http://lists.x.org/mailman/listinfo/xorg" target="_blank">http://lists.x.org/mailman/listinfo/xorg</a> >>>> Your subscription address: <a href="mailto:madman2003@gmail.com">madman2003@gmail.com</a> >>> >>> Have you tried "xrandr --output DVI-I-1 --mode 1680x1050 --rate 120"? >>> >>> -- >>> Far away from the primal instinct, the song seems to fade away, the >>> river get wider between your thoughts and the things we do and say. >> >> >> >> -- >> Best regards, >> >> HacKurx >> <a href="http://www.hackurx.info" target="_blank">www.hackurx.info</a> > > > > -- > Best regards, > > HacKurx > <a href="http://www.hackurx.info" target="_blank">www.hackurx.info</a> -- Far away from the primal instinct, the song seems to fade away, the river get wider between your thoughts and the things we do and say. </div></div></blockquote></div> -- Best regards, HacKurx <a href="http://www.hackurx.info" target="_blank">www.hackurx.info</a>
