When this happens you no longer get the mode lines you used to so that you can't just specify a larger resolution in xorg.conf, you also need to define and appropriate mode line. cvt is one program you can use to generate mode lines. You should check the documentation of your monitor and video card to make sure your don't drive to drive the display out of spec or you may damage something. Below is the xorg.conf I ended up using. Don't blindly use it yourself. The mode line may or may not be appropriate for your equipment. # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" # keyboard added by system-config-display Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105+inet" Option "XkbLayout" "us" EndSection Section "Monitor" Identifier "Monitor0" ModelName "NEC MultiSync LCD2010X" HorizSync 31.0 - 80.0 VertRefresh 56.0 - 85.0 Modeline "1280x1024_70.00" 129.00 1280 1368 1504 1728 1024 1027 1034 1069 -hsync +vsync Option "dpms" EndSection Section "Device" Identifier "Videocard0" Driver "nouveau" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Virtual 1280 1024 Depth 24 Modes "1280x1024_70.00" EndSubSection EndSection -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
