I'm running Ubuntu 14.04 with Gnome. Every time I restart my computer I have to manually set the screen resolution to a lower one.

Why it is not being saved automatically?

Some outputs:

lspci

echo $DESKTOP_SESSION

  • Just to confirm...The initial resolution is 1920x1080 and you switch it back manually to 1280x720? – marc Jan 13 '17 at 23:12
  • @mmmint correct, that is the change I have to do every time I turn on my pc – Zumo de Vidrio Jan 13 '17 at 23:51

    Have you tried setting xrandr changes persistently in ~/.xprofile or xorg.conf? – marc Jan 14 '17 at 0:04
  • @mmmint I did not have a xorg.conf, so I created this one and after reboot changes are saved. Thanks!

Fixed after creating the /etc/X11/xorg.conf file with the following content:

Section "Monitor" Identifier "Monitor0" Modeline "1280x720_60.00"
    74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
EndSection
Section "Screen" 
    Identifier "Screen0"  
    Device "Card0"  
    Monitor "Monitor0"
    SubSection "Display"  
        Modes "1280x1024_60.00" "1024x768_60.00" 
    EndSubSection
EndSection 
Section "Device" 
    Identifier "Card0" 
    Driver "i915" 
EndSection
