I have a similar issue with a 2nd monitor on my system that refuses to
come up in its (native) 1280x1024 mode and will come up as 1024x768 --
the system utility for setting the display resolution doesn't list
1280x1024 as valid for this monitor.
I wrote a script to force this that I run once when I reboot -- I used
to include it in a system start up script (/etc/gdm/Init/Default), but
Fedora 20 has moved stuff around and I haven't found the right place to
include it...
--------------------------------------
# cat set_vga0.sh
#!/bin/bash
#
if [ $( id -u ) -ne 0 ]; then
echo "This has to be run as root"
exit 1
fi
#
xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024
1027 1034 1063 -hsync +vsync
xrandr --addmode VGA-0 1280x1024_60.00
xrandr --output VGA-0 --mode 1280x1024_60.00
-------------------------------------------------------------------
I got the parameters for the 1st xrandr command by running:
cvt 1280 1024
The 2nd xrandr command adds 1280x1024 to the list of valid screen
resolutions for VGA-0
The 3rd one actually sets it into effect.
Disclaimer -- these are dangerous commands! Don't use them unless you
KNOW that your monitor can support the resolution to which you're
setting it! I understand bad things (blown hardware) can happen if you
ignore this.
Hope that helps,
Richard Wilson
