Hello Folks
I've upgraded a server to f20 that was running f14. There was no issue
with screen geometry/ resolution in f14, but now the only resolution
available via gnome is 640x480. That makes the machine virtually
impossible to use in a graphic environment.
I've followed these links here:

But, all to no avail...
I'd really appreciate anybody pointing me in the right direction(s) - I
suspect I've just not done something really straight forward as it seems
I went through tha same kind of issue. Check for the modeline for your
monitor at

There are some other URLs also which you may be interested in, like:

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:(
