Check for the modeline for your monitor at http://www.mythtv.org/wiki/Modeline_Database There are some other URLs also which you may be interested in, like: http://wiki.xbmc.org/?title=Xorg_Modelines http://xtiming.sourceforge.net/cgi-bin/xtiming.pl I tried the xorg.conf way but could not solve the problem, so I went a bit of a different way with the help of some HowTos I have forgotten the links to. So the other way is: Execute xrandr The output might be something like: [root@localhost ~]# xrandr Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192 DisplayPort-0 disconnected (normal left inverted right x axis y axis) HDMI-0 disconnected (normal left inverted right x axis y axis) DVI-0 connected primary 1280x1024+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0 800x600 60.3 56.2 848x480 60.0 640x480 59.9 Check for which output is connected. Here it is DVI-0 Now execute the following commands in sequence. <Sample> xrandr --newmode "1280x1024_60.00" 107.981 1280 1344 1456 1688 1024 1025 1028 1066 +hsync +vsync ^^Name Of New Mode^^ ^^ New Modeline^^ xrandr --addmode DVI-0 "1280x1024_60.00" ^^Your Output Channel^^ ^^Name Of New Mode^^ xrandr --output DVI-0 --mode 1280x1024_60.00 ^^Your Output Channel^^ ^^Name Of New Mode^^ So, without comments, it may look like: xrandr --newmode "1280x1024_60.00" 107.981 1280 1344 1456 1688 1024 1025 1028 1066 +hsync +vsync xrandr --addmode DVI-0 "1280x1024_60.00" xrandr --output DVI-0 --mode 1280x1024_60.00 You have to set the modeline & Output as per your setup in the above lines. If it succeeds then you can put it in a file & execute it as root after every boot. I tried to put it in rc.local but does not work:( HTH -- vikram... |||||||| |||||||| ^^'''''^^||root||^^^'''''''^^ // \\ )) //(( \\// \\ // /\\ || \\ || / )) (( \\ -- Data, n.: An accrual of straws on the backs of theories. -- _ ~|~ = -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
