I am running f22 on a Dell laptop. I have a 23" monitor plugged in and I always use just the external monitor. Everytime I boot it reverts to 1024 X 680 and I have to go to the dispay settings, uncheck the box for both screens the same, turn off the laptop screen & set the external monitor to 1920 X 1080.
there is no xorg.conf file. Here is the xrandr outout:

$ xrandr

   720x400       70.08

how do I get this to boot into this mode everytime??


My previous laptop had a similar issue with Fedora 21, I solved it like this... I created a script named 99-xrandr.sh, placed it in/etc/X11/xinit/xinitrc.d and made it executable by all (owned by root), the script looked like this:

---------------------------------------------------------------------------
#!/bin/bash

/bin/xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync
/bin/xrandr --addmode eDP1 1600x900_60.00
/bin/xrandr --output eDP1 --mode 1600x900_60.00

---------------------------------------------------------------------------


You would want to set it up to force VGA1 to be 1920x1080 like so:

-- run cvt to get the needed string
# cvt 1920 1080
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

Then create your script:

#!/bin/bash

/bin/xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
/bin/xrandr --addmode VGA1 1920x1080_60.00
/bin/xrandr --output VGA1 --mode 1600x900_60.00



Not sure if this will work since your external monitor may not be connected at boot time, but worth a shot


didn't work.. when I rebooted & logged in, xrandr said this:
