Ubuntu graphics resolution 640x480 fix

I stuck with 640x480 for some time ... so here is 3 easy steps to fix it:

Note: Tested on ubuntu 16.04 / 17.10 / 18.04 (bionic)



1) go to native terminal

ctrl+alt+F1


2) disable windows manager (step 1)

sudo lightdm stop


3) create new xorg config file (step 2)

sudo Xorg -configure


4) backup old xorg file ... (optional step for peace of mind)

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak


5) copy new configuration (step 3)

sudo mv /root/xorg.conf.new /etc/X11/xorg.conf


6) start lightdm (didn't work for me)

sudo lightdm start


7) reboot - this actually works!

reboot


and that's it ;-)
