How to set video resolution permanently in Fedora 22?

[David Aldrich]

Hi

I want my Fedora 22 box to run at a video resolution of 1680x1050.

I added and selected that resolution by doing:

$ xrandr --newmode "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
$ xrandr --addmode VGA-0 1680x1050_60.00
$ xrandr --output VGA-0 --mode 1680x1050_60.00

That worked, but when I reboot the resolution reverts to 1280x1024.

I tried creating file:

/etc/X11/xorg.conf.d/40-monitor.conf

and putting in it:

Section "Monitor"
  Identifier  "VGA-0"
  Option      "PreferredMode" "1680x1050_60.00"
EndSection

but that had no effect (perhaps because the resolution was not found after the reboot).

How can I set the resolution to 1680x1050 permanently?

Best regards

David

Back in the day, the following script resided in my ~/.config/autostart:
#!/bin/bash

# add a new mode using xrandr
# works with Lubuntu 14.04 on Pyrope

screen=$(xrandr | grep \ connected | awk '{print $1}')
xrandr --newmode 1680x1050 147.14  1680 1784 1968 2256  1050 1051 1054
1087  -HSync +Vsync
xrandr --addmode $screen 1680x1050
xrandr --output $screen --mode 1680x1050

That won't take effect till you login though, right?

I think I have a virtual machine at home I could never get resolution
to stick on, and I put the xrandr call in a script under /etc/X11/xinit/xinitrc.d/
(if I'm remembering correctly). I believe those get invoked when
X starts, so the resolution will be correct in the login screen as well
(or if that isn't the place, there is some place where scripts get
invoked at X start time :-).
